Dietitian Organisations Endorse Vegetarian Vegan Diets As Healthy for All Stages of Human Life.
From the U.S. Journal of the Academy of Nutrition & Dietetics (2016): “It is the position of the Academy of Nutrition and Dietetics that appropriately planned vegetarian, including vegan, diets are healthful, nutritionally adequate, and may provide health benefits for the prevention and treatment of certain diseases.
These diets are appropriate for all stages of the life cycle, including pregnancy, lactation, infancy, childhood, adolescence, older adulthood, and for athletes…
Vegetarians and vegans are at reduced risk of certain health conditions, including ischemic heart disease, type 2 diabetes, hypertension, certain types of cancer, and obesity.
Low intake of saturated fat and high intakes of vegetables, fruits, whole grains, legumes, soy products, nuts, and seeds (all rich in fiber and phytochemicals) are characteristics of vegetarian and vegan diets that produce lower total and low-density lipoprotein cholesterol levels and better serum glucose control. These factors contribute to reduction of chronic disease…
Plant-based diets are more environmentally sustainable than diets rich in animal products because they use fewer natural resources and are associated with much less environmental damage.”

Dietitians of Canada 2014: “A healthy vegan diet has many health benefits including lower rates of obesity, heart disease, high blood pressure, high blood cholesterol, type 2 diabetes and certain types of cancer… A healthy vegan diet can meet all your nutrient needs at any stage of life including when you are pregnant, breastfeeding or for older adults… A vegan diet includes grains, vegetables, fruit, legumes (dried beans, peas and lentils), seeds and nuts. It excludes meat, fish, poultry, dairy and eggs and products containing these foods…”

Science Journal Reports on Multiple Health Benefits from Plant-based (Vegetarian Vegan) Diets.
From a 2014 report in the Nutrients science journal, that reviewed studies of the Seventh Day Adventists, involving more than 150,000 participants, some excerpts:
“Vegetarian diets confer protection against cardiovascular diseases, cardiometabolic risk factors, some cancers and total mortality. Compared to lacto-ovo-vegetarian diets, vegan diets seem to offer additional protection for obesity, hypertension, type-2 diabetes, and cardiovascular mortality.”
As compared to non-vegetarians the specific findings include:
Mortality (Death Rates): “vegetarians experienced a 10% to 20% decreased [incidence] in all-cause mortality…” & for veganism “14% lower risks of all-cause mortality in males.”
Cardio/Heart Disease: “vegetarians had 26% to 68% lower risks of mortality from ischemic heart disease, cardiovascular disease [CVD], & cerebrovascular disease.” For vegan males, “42% risks reduction in CVD mortality… a 55% risk reduction for ischemic heart disease.”
Hypertension: “vegetarians had 55% lower odds of developing hypertension” while “vegans had 75% risks reduction…”
Cancer: “Vegetarians experienced a 48% risk reduction in mortality from breast cancer…” & “half the risk of developing colon cancer… 23% risk reduction for cancer of the gastrointestinal tract… 35% risk reduction for prostate cancer… lower risk for cancer of the respiratory tract & overall-cancer.”
Type-2 Diabetes: “25% to 49% lower for vegetarians…” & “risks reduction” of “47% to 78% for vegans.”
Body Mass Index (BMI): “vegetarians were approximately 2-4 points lower… vegans had respectively, 3 & 5 points lower BMI…”
And “The odds of developing metabolic syndrome (MetS) for vegetarians were about half compared to non-vegetarians…”
They state they “summarized available evidence from three prospective cohorts of Adventists in North America: Adventist Mortality Study [22,940 participants], Adventist Health Study [34,198 participants], and Adventist Health Study-2 [96,000 participants]…”

A 2015 report in the Public Health Nutrition science journal states that “Compared with non-vegetarians, the vegetarian/vegans had” the following “odds ratios” of:
– 0.56 for hypertension
– 0.48 for diabetes
– 0.42 for high blood total cholesterol
– 0.54 for high blood LDL-cholesterol
– 0.43 for obesity
– 0.54 for abdominal obesity…
“when adjusted for age, gender, education, physical activity and sub-study… Further adjustment for BMI (body mass index) suggested that BMI acts as an intermediary variable between diet and both hypertension and diabetes.”
The authors conclude: “As with non-blacks, these results suggest that there are sizeable advantages to a vegetarian diet in black individuals also…”

From The American Journal of Clinical Nutrition: “There is convincing evidence that vegetarians have lower rates of coronary heart disease, largely explained by low LDL cholesterol, probable lower rates of hypertension and diabetes mellitus, and lower prevalence of obesity. Overall, their cancer rates appear to be moderately lower than others living in the same communities, and life expectancy appears to be greater…
It is probable that using the label “vegetarian” as a dietary category is too broad and that our understanding will be served well by dividing vegetarians into more descriptive subtypes. Although vegetarian diets are healthful and are associated with lower risk of several chronic diseases, different types of vegetarians may not experience the same effects on health.”

Journal of Geriatric Cardiology: “Plant-based diets are associated with lowering overall mortality and ischemic heart disease mortality; reducing medication needs; supporting sustainable weight management; reducing incidence and severity of high-risk conditions, such as obesity and obesity-related inflammatory markers, hyperglycemia, hypertension, and hyperlipidemia; and even reversing advanced cardiovascular disease and type 2 diabetes.
These advantages are likely the result of both the consistent consumption of innate health-promoting compounds found in whole plant foods and the reduction of exposure to harmful substances found in animal products and highly processed foods.”

From a 2016 study published in the journal of Critical Reviews in Food Science and Nutrition: “This comprehensive meta-analysis reports a significant protective effect of a vegetarian diet versus the incidence and/or mortality from ischemic heart disease (-25%) and incidence from total cancer (-8%). Vegan diet conferred a significant reduced risk (-15%) of incidence from total cancer… Eighty-six cross-sectional and 10 cohort prospective studies were included… The overall analysis among cross-sectional studies reported significant reduced levels of body mass index, total cholesterol, LDL-cholesterol, and glucose levels in vegetarians and vegans versus omnivores… Beneficial effects of vegetarian and vegan diets on health outcomes have been supposed in previous studies…”

A 2003 report in the Forum of Nutrition journal states: “Numerous studies show important and quantifiable benefits of the different components of vegetarian diets, namely the reduction of risk for many chronic diseases and the increase in longevity. Such evidence is derived from the study of vegetarians as well as other populations.
While meat intake has been related to increased risk for a variety of chronic diseases, an abundant consumption of vegetables, fruits, cereals, nuts, and legumes all have been independently related with a lower risk for several chronic degenerative diseases, such as ischemic heart disease, diabetes, obesity, and many cancers.
Hence, whole foods of plant origin seem to be beneficial on their own merit for chronic disease prevention… from the public health viewpoint the health benefits of a well-planned vegetarian diet far outweigh the potential risks.”

A 2013 article published in the Permanente Journal is titled “Nutritional Update for Physicians: Plant-Based Diets” The Abstract states: “The objective of this article is to present to physicians an update on plant-based diets. Concerns about the rising cost of health care are being voiced nationwide, even as unhealthy lifestyles are contributing to the spread of obesity, diabetes, and cardiovascular disease. For these reasons, physicians looking for cost-effective interventions to improve health outcomes are becoming more involved in helping their patients adopt healthier lifestyles.
Healthy eating may be best achieved with a plant-based diet, which we define as a regimen that encourages whole, plant-based foods and discourages meats, dairy products, and eggs as well as all refined and processed foods. We present a case study as an example of the potential health benefits of such a diet.
Research shows that plant-based diets are cost-effective, low-risk interventions that may lower body mass index, blood pressure, HbA1C, and cholesterol levels. They may also reduce the number of medications needed to treat chronic diseases and lower ischemic heart disease mortality rates. Physicians should consider recommending a plant-based diet to all their patients, especially those with high blood pressure, diabetes, cardiovascular disease, or obesity.”

From a 1999 study printed in the American Journal of Clinical Nutrition: “Results associating diet with chronic disease in a cohort of 34192 California Seventh-day Adventists are summarized…
Multivariate analyses showed significant associations between beef consumption and fatal ischemic heart disease (IHD) in men…
significant protective associations between nut consumption and fatal and nonfatal IHD in both sexes…
and reduced risk of IHD in subjects preferring whole-grain to white bread.
The lifetime risk of IHD was reduced by ≈31% in those who consumed nuts frequently and by 37% in male vegetarians compared with nonvegetarians.
Cancers of the colon and prostate were significantly more likely in nonvegetarians [ie. cancer is more frequent in the meat eaters]…
and frequent beef consumers also had higher risk of bladder cancer.
Intake of legumes was negatively associated with risk of colon cancer in nonvegetarians and risk of pancreatic cancer.
Higher consumption of all fruit or dried fruit was associated with lower risks of lung, prostate, and pancreatic cancers.
Cross-sectional data suggest vegetarian Seventh-day Adventists have lower risks of diabetes mellitus, hypertension, and arthritis than nonvegetarians.
Thus, among Seventh-day Adventists, vegetarians are healthier than nonvegetarians…”

From a 2016 report titled “The long-term health of vegetarians and vegans” – excerpt: “Vegetarians have a lower prevalence of overweight and obesity and a lower risk of IHD [ischemic heart disease] compared with non-vegetarians from a similar background…
For cancer, there is some evidence that the risk for all cancer sites combined is slightly lower in vegetarians than in non-vegetarians… Vegetarians have also been found to have lower risks for diabetes, diverticular disease and eye cataract.
Overall mortality is similar for vegetarians and comparable non-vegetarians, but vegetarian groups compare favourably with the general population. The long-term health of vegetarians appears to be generally good, and for some diseases and medical conditions it may be better than that of comparable omnivores…”

From a report in Medical Hypotheses titled “Vegan proteins may reduce risk of cancer, obesity, and cardiovascular disease by promoting increased glucagon activity”, some excerpts: “a vegan diet has documented clinical efficacy in rheumatoid arthritis.
Low-fat vegan diets may be especially protective in regard to cancers linked to insulin resistance–namely, breast and colon cancer–as well as prostate cancer; conversely, the high IGF-I activity associated with heavy ingestion of animal products may be largely responsible for the epidemic of ‘Western’ cancers in wealthy societies.
Increased phytochemical intake is also likely to contribute to the reduction of cancer risk in vegans. Regression of coronary stenoses has been documented during low-fat vegan diets coupled with exercise training…
An unnecessarily high intake of essential amino acids–either in the absolute sense or relative to total dietary protein–may prove to be as grave a risk factor for ‘Western’ degenerative diseases as is excessive fat intake.”

Medical Journal of Australia: “A vegetarian diet can easily meet human dietary protein requirements as long as energy needs are met and a variety of foods are eaten. Vegetarians should obtain protein from a variety of plant sources, including legumes, soy products, grains, nuts and seeds… There is no need to consciously combine different plant proteins at each meal as long as a variety of foods are eaten from day to day, because the human body maintains a pool of amino acids which can be used to complement dietary protein. The consumption of plant proteins rather than animal proteins by vegetarians may contribute to their reduced risk of chronic diseases such as diabetes and heart disease…”

A 2012 article in the American Journal of Lifestyle Medicine states: “There is now a significant amount of research that demonstrates the health benefits of vegetarian and plant-based diets, which have been associated with a reduced risk of obesity, diabetes, heart disease, and some types of cancer as well as increased longevity.
Vegetarian diets are typically lower in fat, particularly saturated fat, and higher in dietary fiber. They are also likely to include more whole grains, legumes, nuts, and soy protein, and together with the absence of red meat, this type of eating plan may provide many benefits for the prevention and treatment of obesity and chronic health problems, including diabetes and cardiovascular disease.
Although a well-planned vegetarian or vegan diet can meet all the nutritional needs of an individual, it may be necessary to pay particular attention to some nutrients to ensure an adequate intake, particularly if the person is on a vegan diet. This article will review the evidence for the health benefits of a vegetarian diet and also discuss strategies for meeting the nutritional needs of those following a vegetarian or plant-based eating pattern.”

A 2005 report in the Forum of Nutrition journal states: “A growing body of scientific evidence indicates that wholesome vegetarian diets offer distinct advantages compared to diets containing meat and other foods of animal origin.
The benefits arise from lower intakes of saturated fat, cholesterol and animal protein as well as higher intakes of complex carbohydrates, dietary fiber, magnesium, folic acid, vitamin C and E, carotenoids and other phytochemicals.
Since vegetarians consume widely divergent diets, a differentiation between various types of vegetarian diets is necessary. Indeed, many contradictions and misunderstandings concerning vegetarianism are due to scientific data from studies without this differentiation.
In the past, vegetarian diets have been described as being deficient in several nutrients including protein, iron, zinc, calcium, vitamin B12 and A, n-3 fatty acids and iodine. Numerous studies have demonstrated that the observed deficiencies are usually due to poor meal planning.
Well-balanced vegetarian diets are appropriate for all stages of the life cycle, including children, adolescents, pregnant and lactating women, the elderly and competitive athletes.
In most cases, vegetarian diets are beneficial in the prevention and treatment of certain diseases, such as cardiovascular disease, hypertension, diabetes, cancer, osteoporosis, renal disease and dementia, as well as diverticular disease, gallstones and rheumatoid arthritis.
The reasons for choosing a vegetarian diet often go beyond health and well-being and include among others economical, ecological and social concerns.”

A 2009 report in the American Journal of Clinical Nutrition states: “A vegetarian diet is associated with many health benefits because of its higher content of fiber, folic acid, vitamins C and E, potassium, magnesium, and many phytochemicals and a fat content that is more unsaturated. Compared with other vegetarian diets, vegan diets tend to contain less saturated fat and cholesterol and more dietary fiber. Vegans tend to be thinner, have lower serum cholesterol, and lower blood pressure, reducing their risk of heart disease. However, eliminating all animal products from the diet increases the risk of certain nutritional deficiencies. Micronutrients of special concern for the vegan include vitamins B-12 and D, calcium, and long-chain n-3 (omega-3) fatty acids.* Unless vegans regularly consume foods that are fortified with these nutrients, appropriate supplements should be consumed. In some cases, iron and zinc status of vegans may also be of concern because of the limited bioavailability of these minerals.”

Medical Journal of Australia: “Research has shown that a well planned vegetarian diet can meet nutritional needs for good health and may reduce the risk of cancer, cardiovascular disease, metabolic syndrome, insulin resistance, type 2 diabetes, hypertension, and obesity. Choosing plant-based meals is also environmentally beneficial.
Vegetarian diets are generally lower in saturated fat and cholesterol and higher in dietary fibre, antioxidants and phytochemicals than non-vegetarian diets.
It is likely that the combination of these factors provide vegetarians with a significant health advantage…
nutrient-dense vegetarian diets are more likely to provide additional health benefits, particularly with respect to prevention and treatment of many chronic diseases.”

The Longest Living People in the World? Californian Adventist Vegetarians Live Around 10 Years Longer than the Rest of the Population.
A journal of the American Medical Association reported in 2001 that “Adventist vegetarian men and women have expected ages at death of 83.3 and 85.7 years, respectively. These are 9.5 and 6.1 years, respectively, greater than those of the 1985 California population… To our knowledge, the life expectancies of California Adventist men and women are higher than those of any other well-described natural population…”
The “analysis of 34,192 California Seventh-Day Adventists” was reported in the Archives of Internal Medicine.
The report further states: “High physical activity, frequent consumption of nuts, vegetarian status, and medium body mass index each result in an approximate 1.5- to 2.5-years gain in life expectancy compared with the corresponding high-risk values. The sum of these independent effects (9.7 years in men and 10.4 years in women)…
These results strongly suggest that behavioral choices influence the expected age at death by several years, even as much as a decade…
The extra years of life predicted in these analyses are… quite similar to comparisons between Adventists and others in Norway and the Netherlands… and account for a 10-year difference in life expectancy...
Substantial gains in life expectancy would only be worthwhile if they were also accompanied by a longer period of good-quality life… it was previously shown that the vegetarian Adventists took less medication and had fewer overnight hospital stays, surgical procedures, and x-ray examinations during the previous year. Vegetarians also had a reduced prevalence of several chronic diseases that may degrade the quality of life… persons who choose lower-risk health habits postpone disability…
In conclusion, California Adventists live longer than other Californians, and indeed longer than most, if not all, other formally described populations.”

A 2012 article titled “Why Do Vegetarians Live Longer?” – some excerpts “Nearly a decade of extra life – that’s what you get when you move away from eating animal foods and toward a plant-based diet. This is really exciting science for anyone seeking healthy longevity (and who isn’t?)!
According to a recent report on the largest study of vegetarians and vegans to date, those eating plant-based diets appear to have a significantly longer life expectancy. Vegetarians live on average almost eight years longer than the general population, which is similar to the gap between smokers and nonsmokers. This is not surprising, given the reasons most of us are dying. In an online video, “Uprooting the Leading Causes of Death,” Michael Greger, M.D. explores the role a healthy diet can play in preventing, treating, and even reversing the top 15 killers in the United States.

Science Journal Reports on the Association of Plant-based Diets with Lower Mortality/Death Rates.
A study published in JAMA Internal Medicine in 2013 concludes: “Vegetarian diets are associated with lower all-cause mortality and with some reductions in cause-specific mortality.”
The study was based on “96,469 Seventh-day Adventist men and women recruited between 2002 and 2007”.
The specific results include: “The adjusted hazard ratio (HR) for all-cause mortality in all vegetarians combined vs nonvegetarians was 0.88… The adjusted HR for all-cause mortality in vegans was 0.85… in lacto-ovo-vegetarians, 0.91… in pesco-vegetarians, 0.81… and in semi-vegetarians, 0.92… compared with nonvegetarians. Significant associations with vegetarian diets were detected for cardiovascular mortality, noncardiovascular noncancer mortality, renal mortality, and endocrine mortality…”
Compared to omnivores (or non-vegetarians) “Vegans had significantly reduced risk” with these hazard ratios of:
– 0.45 in men for ischemic heart disease mortality; 55% less.
– 0.58 in men for cardiovascular disease mortality; 42% less.
– 0.70 in women for “other mortality”; 28% less.
– 0.72 in men for all-cause mortality; 28% less.
– 0.74 for “other mortality” in both sexes; 26% less.
– 0.81 in men for cancer mortality; 19% less.

The Epidemiology journal published a report in 1992 titled “Mortality pattern of German vegetarians after 11 years of follow-up.” Excerpts: “mortality from all causes was reduced by one-half compared with the general population…
The lowest mortality was found for cardiovascular diseases (SMR = 0.39 for men, 0.46 for women); in particular, for ischemic heart diseases, mortality was reduced to one-third of that expected.
Cancer mortality was reduced by one-half in men (SMR = 0.48), but only by one-quarter in women (SMR = 0.74). The deficit in cancer deaths was mainly observed for lung cancer and gastrointestinal cancers in males and for gastrointestinal cancers in females.
Deaths from diseases of the respiratory and digestive systems were also reduced by about 50%...”

Vegans had the lowest occurrence of breast cancer from “a prospective cohort of 96,001 subjects” as reported in 2016 in The British Journal of Nutrition. An excerpt: “As compared with non-vegetarians, all vegetarians combined did not have a significantly lower risk (hazard ratio (HR) 0·97…). However, vegans showed consistently lower… point estimates when compared with non-vegetarians (all cases: HR 0·78…). In summary, participants in this cohort who follow a vegetarian dietary pattern did not experience a lower risk of BC as compared with non-vegetarians, although lower risk in vegans is possible…”

A 2011 report in Cancer Management and Research states: “Most large prospective observational studies show that vegetarian diets are at least modestly cancer protective (10%–12% reduction in overall cancer risk)…
a broad body of evidence links specific plant foods such as fruits and vegetables, plant constituents such as fiber, antioxidants and other phytochemicals, and achieving and maintaining a healthy weight to reduced risk of cancer diagnosis and recurrence.
Also, research links the consumption of meat, especially red and processed meats, to increased risk of several types of cancer.
Vegetarian and vegan diets increase beneficial plant foods and plant constituents, eliminate the intake of red and processed meat, and aid in achieving and maintaining a healthy weight. The direct and indirect evidence taken together suggests that vegetarian diets are a useful strategy for reducing risk of cancer.”

Regards coronary heart disease (CHD) a 2018 report in the American Journal of Clinical Nutrition concluded, from study of 63,442 women and 29,942 men: “plant-based foods are the preferable sources of [monounsaturated fatty acids] MUFAs for CHD prevention.”
Specifically they found that when MUFAs from plant sources (MUFA-Ps) “were modeled to isocalorically replace other macronutrients” the Hazard Ratios (HRs) of CHD were as follows:
– 0.83 for saturated fatty acids (SFAs); representing 17% less CHD for MUFA-Ps.
– 0.86 for refined carbohydrates; 14% less CHD.
– 0.80 for trans fats; 20% less CHD.
Regards MUFAs from animals sources (MUFA-As) they found higher HRs of:
– 1.04 for SFAs; representing 4% more CHD for MUFA-As.
– 1.11 for refined carbohydrates; 11% more CHD.
– 0.88 for trans fats; 12% less CHD.
They state: “we further estimated CHD risk when the sum of MUFA-As and SFAs… was replaced by MUFA-Ps, and found that the HR was 0.81… for this replacement.”
In other words consuming monounsaturated fatty acids from plant foods is associated with a 19% lower rate of coronary heart disease (CHD) as compared to animal sources.

Regards cardiovascular disease this 2015 report in Permanente Journal:
“A plant-based diet is increasingly becoming recognized as a healthier alternative to a diet laden with meat. Atherosclerosis associated with high dietary intake of meat, fat, and carbohydrates remains the leading cause of mortality in the US…
Polyphenols derived from dietary plant intake have protective effects on vascular endothelial cells, possibly as antioxidants that prevent the oxidation of low-density lipoprotein.
Recently, metabolites of L-carnitine, such as trimethylamine-N-oxide [TMAO], that result from ingestion of red meat have been identified as a potential predictive marker of coronary artery disease (CAD).
Metabolism of L-carnitine by the intestinal microbiome is associated with atherosclerosis in omnivores but not in vegetarians, supporting CAD benefits of a plant-based diet.
Trimethylamine-N-oxide may cause atherosclerosis via macrophage activation…
This review provides a mechanistic perspective of the evidence for protection by a plant-based diet against atherosclerotic CAD.”

In 2017 Circulation journal reported a study regards plant-based diets reducing the risks of atherosclerosis. That is the build up of plaque inside arteries that raises the risks of heart attack, stroke and other cardiovascular disease.
Notes from the report: “Lipoprotein(a) [Lp(a)] is a highly atherogenic lipoprotein and is minimally effected by lifestyle changes.”
The report’s conclusion states: “A defined, plant-based diet has a favorable impact on Lp(a) and other atherogenic lipoproteins and particles. Lp(a) concentration was previously thought to be only minimally altered by interventions. In this protocol however, a defined plant-based diet was shown to have a significant impact on this biomarker.”
Specifically, within just 4 weeks on “a defined, plant-based diet… Significant reductions were observed for serum Lp(a), total cholesterol, LDL-C, HDL-C, triglycerides, apolipoprotein B, LDL particles, small-dense LDL-C, HDL2-C and apolipoprotein A-1.

Regards dietary fats and cardiovascular disease the American Heart Association reports on a 2018 study: “Mono-unsaturated fats from plants, not animals may reduce risk of death from heart disease and other causes.”
Further notes: “The largest reductions in the risk of death were found when healthy fats from plant sources replaced saturated fats, trans fats and refined carbohydrates.”
Analyzing the diet information related to 20,672 deaths over an average 22 years of follow-up, “the researchers found:
+ Participants with a higher intake of mono-unsaturated fatty acids from plants had a 16 percent lower risk of death from any cause compared to those with lower intakes.
+ Participants with a higher intake of mono-unsaturated fatty acids from animals had a 21 percent higher risk of death from any cause.
+ Replacing saturated fats, refined carbohydrates (like simple sugars) or trans fats with an equal number of calories (2 percent – 5 percent of the total) from mono-unsaturated fatty acids from plants might lower the risk of heart disease deaths and death from any cause between 10 percent and15 percent.
+ Replacing mono-unsaturated fatty acids from animals with an equal amount of calories (5 percent of the total) of mono-unsaturated fatty acids from plants might lower the risk of heart disease deaths and deaths from any cause between 24 percent to 26 percent…”

The International Journal of Epidemiology published a study in 2018 regards cardiovascular disease (CVD). They found that those who consume higher amounts of meat protein had a 60% increased death rate from cardiovascular disease (CVD). In contrast, people who obtain a high intake of protein from nuts and seeds had a 40 % reduction in CVD mortality.
The study covered 81,337 men and women with 2276 CVD deaths during a mean follow-up time of 9.4 years. The hazard ratios they found for CVD mortality were:
– 1.61 for the ‘Meat’ protein factor.
– 0.60 for the ‘Nuts & Seeds’ protein factor.
These being “highest vs lowest quintile of factor scores”.
Further notes: “No significant associations were found for the ‘Grains’, ‘Processed Foods’ and ‘Legumes, Fruits & Vegetables‘ protein factors. Additional adjustments for the participants’ vegetarian dietary pattern and nutrients related to cardiovascular disease outcomes did not change the results.”

Regards coronary heart disease (CHD) the Journal of the American College of Cardiology reported in 2017: “Higher intake of a plant-based diet index rich in healthier plant foods is associated with substantially lower CHD risk, whereas a plant-based diet index that emphasizes less-healthy plant foods is associated with higher CHD risk.”
The study included more than 200,000 people.
Regards definitions: “healthy plant foods (whole grains, fruits/vegetables, nuts/legumes, oils, tea/coffee)… whereas less-healthy plant foods (juices/sweetened beverages, refined grains, potatoes/fries, sweets)…”
Regards specific results they found that higher adherence to a plant-based diet overall “was independently inversely associated with CHD” with a hazard ratio [HR] of 0.92; meaning 8% lower incidence of CHD.
Furthermore the “inverse association was stronger” for the healthy plant-based diet with HR of 0.75; meaning 25% less CHD.
In contrast the unhealthy plant-based diet “was positively associated with CHD” with an HR of 1.32; meaning a 32% higher rate of CHD.

A 2017 report in Nutrients science journal states: “Cardio-metabolic disease, namely ischemic heart disease, stroke, obesity, and type 2 diabetes, represent substantial health and economic burdens. Almost one half of cardio-metabolic deaths in the U.S. might be prevented through proper nutrition.
Plant-based (vegetarian and vegan) diets are an effective strategy for improving nutrient intake. At the same time, they are associated with decreased all-cause mortality and decreased risk of obesity, type 2 diabetes, and coronary heart disease.
Evidence suggests that plant-based diets may reduce the risk of coronary heart disease events by an estimated 40% and the risk of cerebral vascular disease events by 29%.
These diets also reduce the risk of developing metabolic syndrome and type 2 diabetes by about one half.
Properly planned vegetarian diets are healthful, effective for weight and glycemic control, and provide metabolic and cardiovascular benefits, including reversing atherosclerosis and decreasing blood lipids and blood pressure. The use of plant-based diets as a means of prevention and treatment of cardio-metabolic disease should be promoted through dietary guidelines and recommendations.”

From the British Journal of Nutrition: “The prevalence of the metabolic syndrome (MetS) in the USA is approximately 20 % and is currently increasing in developing countries in line with the obesity epidemic. The health care costs associated with the MetS are on a magnitude of 1.6 overall compared with healthy individuals, which makes it an important public health problem.
Current evidence from several cross-sectional and case-control studies shows an association between consumption of a vegetarian dietary pattern and a reduced prevalence or risk of developing the MetS.”

From a 2015 report in the British Journal of Nutrition: “Several previous cross-sectional studies have shown that vegetarians have a better metabolic profile than non-vegetarians, suggesting that a vegetarian dietary pattern may help prevent chronic degenerative diseases…
We studied how several sub-types of vegetarian diets affect metabolic traits, including waist circumference, BMI, systolic blood pressure (SBP), diastolic blood pressure, fasting blood glucose, total cholesterol (TC), HDL, LDL, TAG and TC:HDL ratio…
In the cross-sectional comparisons, all sub-types of vegetarians had lower likelihoods of abnormalities compared with non-vegetarians on all metabolic traits (P<0·001 for all comparisons), except for HDL and TAG.
The better metabolic profile in vegetarians is partially attributable to lower BMI. With proper management of TAG and HDL, along with caution about the intake of refined carbohydrates and fructose, a plant-based diet may benefit all aspects of the metabolic profile.
In the longitudinal follow-up, each additional year of vegan diet lowered the risk of obesity by 7 %… whereas each additional year of lacto-vegetarian diet lowered the risk of elevated SBP by 8 %… and elevated glucose by 7 %… and each additional year of ovo-lacto-vegetarian diet increased abnormal HDL by 7 %… compared with non-vegetarians.”

Science Journal Reports on the Association of Plant-based Diets with Lower BMI & Improved Weight Management.
Regards BMI, weight management & obesity issues a Dr Greger clip reports on a study in Diabetes Care that found “only the vegans are on average a healthy weight.” And even though “the vegans exercised less” they were on average 40 pounds lighter than meat-eaters.
The study compared the body mass index of vegans, vegetarians, flexitarians and omnivores.
Further excerpts: “A BMI over 30 is considered obese; between 25 and 30, overweight; and they used to call under 25 “normal” weight—but it’s no longer the norm. The average BMI in this country is now 28.8…
A flexitarian is a “flexible vegetarian,” who in this study is defined as someone who eats meat once or twice a month, but is basically vegetarian… even the flexitarians are overweight… even the vegetarians are overweight… they are a significantly healthier weight than those who eat meat even only a few times a month…
only the vegans are, on average, a healthy weight. And that’s like a 40-pound spread between vegans and meat-eaters, which is pretty dramatic.
But maybe it’s not their diet; maybe vegans just tend to exercise more? No. They carefully measured activity levels, and if anything, the vegans in this study exercised less than the meat-eaters. Lazy vegans! But still, on average, 40 pounds lighter.”
From a journal of the American Diabetes Association: “Mean BMI was lowest in vegans (23.6 kg/m2) and incrementally higher in lacto-ovo vegetarians (25.7 kg/m2), pesco-vegetarians (26.3 kg/m2), semi-vegetarians (27.3 kg/m2), and nonvegetarians (28.8 kg/m2)…
The 5-unit BMI difference between vegans and nonvegetarians indicates a substantial potential of vegetarianism to protect against obesity.”

Vegetarian diets should be recommended for weight management; however, care should be taken to optimize food intake to provide adequate intakes of nutrients of concern when energy restriction is used in conjunction with a vegetarian dietary pattern.
At any caloric amount, vegetarians should optimize intakes of vitamin B12, zinc, and protein; and both vegetarians and nonvegetarians need to increase intakes of calcium, magnesium, fiber, and vitamins A, C, and E”

Regards inflammation, fibromyalgia and arthritis, notes from a study testing a vegan “living food” diet, as published by the Hungarian Academy of Sciences:
“We have performed a number of studies including dietary interventions and cross-sectional studies on subjects consuming uncooked vegan food called living food (LF) and clarified the changes in several parameters related to health risk factors.
LF consists of germinated seeds, cereals, sprouts, vegetables, fruits, berries and nuts. Some items are fermented and contain a lot of lactobacilli. The diet is rich in fiber. It has very little sodium, and it contains no cholesterol. Food items like berries and wheat grass juice are rich in antioxidants such as carotenoids and flavonoids.
The subjects eating living food show increased levels of carotenoids and vitamins C and E and lowered cholesterol concentration in their sera. Urinary excretion of sodium is only a fraction of the omnivorous controls. Also urinary output of phenol and p-cresol is lowered as are several fecal enzyme levels which are considered harmful.
The rheumatoid arthritis patients eating the LF diet reported amelioration of their pain, swelling of joints and morning stiffness which all got worse after finishing LF diet. The composite indices of objective measures showed also improvement of the rheumatoid arthritis patients during the intervention…
Rheumatoid patients subjectively benefited from the vegan diet which was also seen in serum parameters and fecal analyses…
The fibromyalgic subjects eating LF lost weight compared to their omnivorous controls. The results on their joint stiffness and pain… their quality of sleep… all improved.
It appears that the adoption of vegan diet exemplified by the living food leads to a lessening of several health risk factors to cardiovascular diseases and cancer.”

From a related report in Toxicology journal, on the benefits of vegan living food (LF) diet: “The shift of fibromyalgic subjects to LF resulted in a decrease of their joint stiffness and pain as well as an improvement of their self-experienced health.
The rheumatoid arthritis patients eating the LF diet also reported similar positive responses and the objective measures supported this finding. The improvement of rheumatoid arthritis was significantly correlated with the day-to-day fluctuation of subjective symptoms.
In conclusion the rheumatoid patients subjectively benefited from the vegan diet rich in antioxidants, lactobacilli and fibre, and this was also seen in objective measures.”

Science Journal Reports on the Association of Plant-based Diets with Improved Microbiota & Gut Health.
Regards inflammation and diabetes risk, a 2017 study in the journal Diabetology & Metabolic Syndrome is titled “Worse inflammatory profile in omnivores than in vegetarians associates with the gut microbiota composition.”
The conclusion: “There are differences in gut microbiota composition of individuals with distinct dietary habits, who differ according to their inflammatory and metabolic profiles. Based on the findings relative to bacteria abundances and on their recognized actions in the metabolism, we suggest that exposure to animal foods may favor an intestinal environment which could trigger systemic inflammation and insulin resistance-dependent metabolic disorders.”

Science Journal Reports Comparing & Showing Plant-based Diets Have Superior Nutritional Quality.
A study published in the Journal of the American Dietetic Association examined: “the relationship between prototype popular diets and diet quality as measured by the healthy eating index (HEI), consumption patterns, and body mass index (BMI).
The prototype diets included vegetarian (no meat, poultry, or fish on day of survey) and non-vegetarian.
The nonvegetarian group was further subdivided into low carbohydrate (less than 30% of energy from carbohydrate), medium (30% to 55%), and high (greater than 55% of energy)…
10,014 adults, aged 19 years and older… were included in the analyses of extant data…
Review of the literature suggests that weight loss is independent of diet composition. Energy restriction is the key variable associated with weight reduction in the short term…
Findings include: “Diets that are high in carbohydrate and low to moderate in fat tend to be lower in energy. The lowest energy intakes were observed for those on a vegetarian diet. The diet quality as measured by HEI was highest for the high carbohydrate groups and lowest for the low carbohydrate groups. The BMIs were significantly lower for men and women on the high carbohydrate diet; the highest BMIs were noted for those on a low carbohydrate diet.”

A 2014 article in The Atlantic titled “Science Compared Every Diet, and the Winner Is Real Food.”
Excerpts: “Researchers asked if one diet could be crowned best in terms of health outcomes. If diet is a set of rigid principles, the answer is a decisive no. In terms of broader guidelines, it’s a decisive yes…
Scientific publisher Annual Reviews asked Katz to compare the medical evidence for and against every mainstream diet…
Katz and Yale colleague Stephanie Meller published their findings in the current  issue of the journal in a paper titled, “Can We Say What Diet Is Best for Health?” In it, they compare the major diets of the day…
A diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention…
Among the salient points of proven health benefits the researchers note, nutritionally-replete plant-based diets are supported by a wide array of favorable health outcomes, including fewer cancers and less heart disease. These diets ideally included not just fruits and vegetables, but whole grains, nuts, and seeds…
If you focus on real food, nutrients tend to take care of themselves…
Exaggerated emphasis on a single nutrient or food is inadvisable…
“The evidence that with knowledge already at our disposal, we could eliminate 80 percent of chronic disease is the basis for everything I do,” Katz said. Just as he was finishing his residency in internal medicine in 1993, influential research in the Journal of the American Medical Association (“Actual Causes of Death in the United States”) put diet on a short list of the lifestyle factors blamed for half of deaths in 1990. “Here we are more than 20 years later and we’ve made just about no progress.”…
in a notable blow to some interpretations of the Paleo diet, Katz and Meller wrote, “if Paleolithic eating is loosely interpreted to mean a diet based mostly on meat, no meaningful interpretation of health effects is possible.” They note that the composition of most meat in today’s food supply is not similar to that of mammoth meat, and that most plants available during the Stone Age are today extinct…”

Regards bone health a 2015 report in the Nutrients science journal states: “These data suggest that plant-based diets are not detrimental to bone in young adults. Moreover, diet prescriptions for bone health may vary among diet groups: increased fruit and vegetable intake for individuals with high meat intakes and increased plant protein intake for individuals who follow a vegetarian diet plan.”

Regards bone health a 2016 report in Swiss Medical Weekly states: “Vegetarian and vegan diets contain low amounts of protein and calcium. For this reason they are supposed to cause low bone mineral density (BMD) and osteoporosis.
But this is not the case, except for vegans with a particularly low calcium intake. The absence of osteoporosis or low BMD can be explained by the low acid load of these diets.
Nutritional acid load is negatively correlated with bone mineral density (BMD) and positively with fracture risk. Low acid load is correlated with lower bone resorption and higher BMD. It is linked to high intake of potassium-rich nutrients, such as fruits and vegetables, as found in vegetarian diets.
The total nutritional acid load, which not only depends on the potassium content of the nutrition, was recently assessed in several studies on vegetarian and vegan diets and was found to be very low or absent, while the diet of Western-style omnivores produces daily 50 to 70 mEq of acid. This might be an important factor for the protection of vegetarians from osteoporosis.”

Regards bone health a 2014 report in the American Journal of Clinical Nutrition states: “Vegan diets are not associated with an increased fracture risk if calcium intake is adequate.

European Journal of Clinical Nutrition: “In this population, fracture risk was similar for meat eaters, fish eaters and vegetarians. The higher fracture risk in the vegans appeared to be a consequence of their considerably lower mean calcium intake. An adequate calcium intake is essential for bone health, irrespective of dietary preferences…
Among subjects consuming at least 525 mg/day calcium the corresponding incidence rate ratios were 1.05 (0.90–1.21) for fish eaters, 1.02 (0.90–1.15) for vegetarians and 1.00 (0.69–1.44) for vegans.”
In other words vegans who consume that amount have risk that is equal to the meat eaters and slightly better than the vegetarians and fish eaters. Some vegans even had the lowest incidence rates (0.69) of all groups, representing a 31% reduced incidence. Although some had the highest at 1.44.
The study covered 7,947 men and 26,749 women.

Taken together, findings suggest that ultimately, vegans do not differ much from omnivores in their eating attitudes and behaviors, and when they do, differences indicate slightly healthier attitudes and behaviors towards food. Similarly, vegans closely resembled omnivores in non-eating related health behaviors.”

Video & Article Reports from Medical Doctors on the Health Benefits of Vegetarian & Vegan Diets.
Dr Michael Greger’s NutritionFacts.org has 2000+ video clips (most are short) based on science journal reports about: i) the impressive health benefits of plant-based eating (ie. veganism, vegetarianism); and ii) the higher rates of disease and death associated with eating red meat, dairy, chicken, eggs and fish.
Two of the more comprehensive presentations are:
1] “Food as Medicine: Preventing and Treating the Most Common Diseases with Diet” (2015) at https://www.youtube.com/watch?v=d0IhZ-R1O8g
Summary: “Dr. Greger has scoured the world’s scholarly literature on clinical nutrition and developed this new presentation based on the latest in cutting edge research exploring the role diet may play in preventing, arresting, and even reversing some of our most feared causes of death and disability.”
For the text transcript see: https://nutritionfacts.org/video/food-as-medicine/
2] “Uprooting the Leading Causes of Death” (2012) at https://www.youtube.com/watch?v=30gEiweaAVQ
Summary: “Death in America is largely a foodborne illness. Focusing on studies published just over the last year in peer-reviewed scientific medical journals, Dr. Greger offers practical advice on how best to feed ourselves and our families to prevent, treat, and even reverse many of the top 15 killers in the United States.”

Dr T. Colin Campbell, PhD: “The data from the China Project suggest that what we have come to consider as “normal” illnesses of aging are really not normal. In fact, these findings indicate that the vast majority perhaps 80 to 90% of all cancers, cardiovascular diseases, and other forms of degenerative illness can be prevented, at least until very old age, simply by adopting a plant-based diet.”
“T. Colin Campbell, PhD has been at the forefront of nutrition research for over forty years. His legacy, the China Project, has been acknowledged as the most comprehensive study of health and nutrition ever conducted. Dr. Campbell is the Jacob Gould Schurman Professor Emeritus of Nutritional Biochemistry at Cornell University.”

From an article titled “7 Things That Happen When You Stop Eating Meat” by Dr Michelle McMacken MD – summary of points: “1. You’ll reduce inflammation in your body… 2. Your blood cholesterol levels will plummet… 3. You’ll give your microbiome a makeover… 4. You’ll change how your genes work… 5. You’ll dramatically reduce your chances of getting type 2 diabetes… 6. You’ll get the right amount—and the right type—of protein… 7. You’ll make a huge impact on the health of our planet and its inhabitants…”

Excerpts from a 2017 article titled “Vegetarian diets and health: the voice of science needs to be heard” by Professor of Nutrition, Francois Mariotti:
“Based on the scientific literature available, it is clear that a diet predominantly based on plants is associated with many health benefits for the general population…
A scientific approach offers an opportunity to separate such questions from the surrounding debates, and address them rigorously and in their entirety. To achieve this goal, approximately 100 international academics came together to produce 45 chapters of what would become ‘Vegetarian and Plant-Based Diets in Health and Disease Prevention’.
The book looks at the subject from all analytical angles, positive and negative, and considers the whole spectrum of vegetarian diets. It discusses their overall benefits with respect to health and disease risk and also the nutritional problems that can potentially arise for those who adopt them…
One such shortcut is “just eat less meat and other animal products”. No. First, there is no “just do it” in the complex field of nutrition. Second, if you eat less of one thing, you will eat more of something else. And if you simply eat more of what now constitutes your diet, it is very unlikely that this will lead you in the right direction.
For example, a marked reduction in animal-product consumption must be accompanied by an increase in protein-rich plant foods, such as legumes.
Another shortcut is “Just eat plant-based foods”. But a diet made up of potato chips, ketchup, sodas, sugar-packed breakfast cereals and processed white bread covered with hazelnut spread is predominantly plant-based. Indeed, these foods could even be labelled “vegan”. But it’s self-evident that such a diet shouldn’t be adopted, particularly given that it will not be associated with any health benefits.
On the other hand, a diverse and predominantly plant-based diet made up of fruits and vegetables, legumes, nuts, seeds and whole grains and rich in raw products will be good for you…”
