If you’re here because of the “drama”, congratulations, I am too apparently. If you’re also here with the position that a vegan diet is unhealthy in humans, I’m begging you for a toilet break’s worth of your time. The contents of this post are wholly divorced from ethics or environmental concerns, are not here to “own you with facts and logic”, and are focused solely on human health through the quoting of scientific literature. For as many of these as I can, I have provided links to the full text on the NCBI’s PubMed Commons in the interest of transparency.

  • 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 […] 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. —Journal of the Academy of Nutrition and Dietetics (2016)
  • Based on this systematic review of randomized clinical trials, there is an overall robust support for beneficial effects of a plant-based diet on metabolic measures in health and disease. —Translational Psychiatry (2019)
  • In most countries a vegan diet has less energy and saturated fat compared to omnivorous control diets, and is associated with favourable cardiometabolic risk profile including lower body weight, LDL cholesterol, fasting blood glucose, blood pressure and triglycerides. —PLoS One meta-analysis (2018)
  • 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. —Critical Reviews in Food Science and Nutrition (2017)
  • The present systematic review and meta-analysis showed a 15% and a 21% reduction in the relative risk of CVD and IHD, respectively, for vegetarians compared to nonvegetarians, but no clear association was observed for total stroke or subtypes of stroke. In addition, an 18% reduction in the relative risk of IHD was observed among vegans when compared to nonvegetarians, although this association was imprecise. —European Journal of Nutrition (2023)
  • Adequate intake of dietary fiber is associated with digestive health and reduced risk for heart disease, stroke, hypertension, certain gastrointestinal disorders, obesity, type 2 diabetes, and certain cancers. According to consumer research, the public is aware of the benefits of fiber and most people believe they consume enough fiber. However, national consumption surveys indicate that only about 5% of the population meets recommendations, and inadequate intakes have been called a public health concern […] The IOM defines total fiber as the sum of dietary fiber and functional fiber. Dietary fiber includes nondigestible carbohydrates and lignins that are intrinsic and intact in plants; functional fiber includes isolated, nondigestible carbohydrates that have beneficial physiological effects in humans. Common sources of intrinsic fiber include grain products, vegetables, legumes, and fruit. —American Journal of Lifestyle Medicine (2017)
  • [R]ecommendations to increase fruit and vegetable consumption, while decreasing saturated fat and dairy intake, are supported [for asthma] by the current literature. Mediterranean and vegan diets emphasizing the consumption of fruits, vegetables, grains, and legumes, while reducing or eliminating animal products, might reduce the risk of asthma development and exacerbation. Fruit and vegetable intake has been associated with reduced asthma risk and better asthma control, while dairy consumption is associated with increased risk and might exacerbate asthmatic symptoms. —Nutrition Reviews (2020)
  • Over the past two decades, a substantial body of consistent evidence has emerged at the cellular and molecular level, elucidating the numerous benefits of a plant-based diet (PBD) for preventing and mitigating conditions such as atherosclerosis, chronic noncommunicable diseases, and metabolic syndrome. —Nutrients comprehensive review (2023)
  • Consumption of vegetarian diets, particularly vegan diets, is associated with lower levels of plasma lipids, which could offer individuals and healthcare professionals an effective option for reducing the risk of heart disease or other chronic conditions. —Nutrition Reviews systematic review and meta-analysis (2017)
  • After adjusting for basic demographic characteristics, medical specialty, and health behaviours (smoking, physical activity) in model 2, participants who followed plant-based diets had 73% lower odds of moderate-to-severe COVID-19 (OR 0.27, 95% CI 0.10 to 0.81) compared with participants who did not follow plant-based diets. Similarly, participants who followed either plant-based diets or pescatarian diets had 59% lower odds of moderate-to-severe COVID-19 (OR 0.41, 95% CI 0.17 to 0.99) compared with those who did not follow these diets. —British Medical Journal (2021)
  • Current research suggests that switching to a plant-based diet may help increase the diversity of health-promoting bacteria in the gut. However, more research is needed to describe the connections between nutrition, the microbiome, and health outcomes because of their complexity and individual heterogeneity. —Nutrients systematic review (2023)
  • [T]his systematic review shows that plant-based diets and their components might have the potential to improve cancer prognosis, especially for breast, colorectal and prostate cancer survivors. —Current Nutrition Reports (2022)
  • The data discussed in this systematic review allow us to conclude that plant-based diets are associated with lower BP and overall better health outcomes (namely, on the cardiovascular system) when compared with animal-based diets. —Current Hypertension Reports (2023)
  • The present systematic review provides evidence that vegan and vegetarian diets are associated with lower CRP levels, a major marker of inflammation and a mediator of inflammatory processes. —Scientific Reports (2020)
  • Evidence strongly suggests that plant-based dietary patterns that are abundant in fruits, vegetables, nuts, seeds, legumes, and whole grains with less emphasis on animal foods and processed foods are a useful and a practical approach to preventing chronic diseases. Such dietary patterns, from plant-exclusive diets to plant-centered diets, are associated with improved long-term health outcomes and a lower risk of all-cause mortality. Given that neurodegenerative disorders share many pathophysiological mechanisms with CVD, including oxidative stress, inflammation, and vascular damage, it is reasonable to deduce that plant-based diets can ameliorate cognitive decline as well. —Advances in Nutrition (2019)
  • This umbrella review offers valuable insights on the estimated reduction of risk factors for cardiometabolic diseases and cancer, and the CVDs-associated mortality, offered by the adoption of plant-based diets through pleiotropic mechanisms. Through the improvement of glycolipid profile, reduction of body weight/BMI, blood pressure, and systemic inflammation, A/AFPDs significantly reduce the risk of ischemic heart disease, gastrointestinal and prostate cancer, as well as related mortality. —PLoS One (2024)
  • In this community‐based cohort of US adults without cardiovascular disease at baseline, we found that higher adherence to an overall plant‐based diet or a provegetarian diet, diets that are higher in plant foods and lower in animal foods, was associated with a lower risk of incident cardiovascular disease, cardiovascular disease mortality, and all‐cause mortality. —Journal of the American Heart Association (2019)
  • In this meta-analysis of prospective observational studies, we found that greater adherence to a plant-based dietary patterns was inversely associated with the risk of type 2 diabetes. These findings were broadly consistent across subgroups defined by various population characteristics and robust in sensitivity analyses.—JAMA Internal Medicine (2019)
  • Our findings suggest that a shift in diet from a high consumption of animal-based foods, especially red and processed meat, to plant-based foods (e.g., nuts, legumes, and whole grains) is associated with a lower risk of all-cause mortality, CVD, and T2D. Thus, a change in dietary habits towards an increment of plant-based products appears to be important for cardiometabolic health. —BMC Medicine systematic review and meta-analysis (2023)
  • Not only is there a broad expansion of the research database supporting the myriad benefits of plant-based diets, but also health care practitioners are seeing awe-inspiring results with their patients across multiple unique subspecialties. Plant-based diets have been associated with lowering overall and ischemic heart disease mortality; supporting sustainable weight management; reducing medication needs; lowering the risk for most chronic diseases; decreasing the incidence and severity of high-risk conditions, including obesity, hypertension, hyperlipidemia, and hyperglycemia; and even possibly reversing advanced coronary artery disease and type 2 diabetes. —The Permanente Journal (2016)

      You might as well say modern men are men by every scientific definition (and subsequently evolved to be able to dominate women). Regardless if that’s true, that doesn’t mean that men inherently need to dominate women. Just like omnivorous humans don’t inherently need to dominate non-human animals. They can choose to be respectful and ethical instead since we’re moral agents capable of rising beyond our basal, animalistic instincts and even our evolutionarily-programmed nature. We’re also able to make more rational and informed choices about what benefits ourselves, other animals, and the planet the most, regardless of what’s natural. Natural doesn’t automatically equal better, in a lot of cases it’s worse. This (your argument) is just an appeal to nature fallacy.

      To be clear, us being omnivores means we’ve evolved to be able to eat from plant- or animal-based (as well as fungal, algal, etc) sources. That doesn’t mean we need to eat all of them, we’re capable of surviving on either, and evidence shows we actually thrive on a plant-based diet. It’s also worth acknowledging that we originally evolved from frugivorous herbivores before we started hunting animals (yes, really), and our bodies, while they have developed some omnivorous adaptations, are still closer to that of herbivores than carnivores and lean more towards the herbivorous side even compared to most other omnivores. But that’s mostly irrelevant to what we’re actually able to do, what we’re shown to be healthiest (and most longevous/long-lived) when doing today, what’s most ethical, sustainable, etc. Just some food for thought.
