    • A widespread lie is that the vegan diet is “clinically proven to reverse heart disease”. The studies by Ornish and Esselstyn are made to sell their diet, but rely on confounding factors like exercise, medication or previous bypass surgeries (Esselstyn had nearly all of them exercise while pretending it was optional). All of them have tiny sample size, extremely poor design and have never been replicated in much larger clinical trials, which made Ornish suggest that we should discard the scientific method. Both diets included dairy.

    • Vegan diets are devoid of many nutrients and generally require more supplements than just B12. Some of them (Vitamin K2, EPA/DHA, Vitamin A) can only be obtained because they are converted from other sources, which is inefficient, limited or poor for a large part of the population. EPA+DHA from animal products have an anti-inflammatory effect, but converting it from ALA (plant sourced) does not seem to work the same. Taurine is essential  for many people with special needs, while Creatine supplementation improves memory only in those who don’t eat meat.

    • The US supplement industry is poorly regulated and has a history of spiking their products with drugs. Vitamin B complexes were tainted with anabolic steroids in the past, while algae supplements have been found to contain aldehydes. Supplements and fortified foods can cause poisoning, while natural products generally don’t. Even vegan doctors caution and can’t agree on what to supplement.

    • There is an extremely strong link between meat abstention and mental disorders. While it’s unknown what causes what, the vegan diet is low in or devoid of several important brain nutrients.

      Stop citing random blogs

      and this time a random pastebin look at a few YouTuber comments?

      It seems your view of scientific evidence is very based on individuals. You’re now focusing on focus on the claims of a very specific type not even plant-based diet and using that to disregard the claims of other evidence about heart disease. There have been RCT studies on it, for instance

      Nevertheless, several RCTs have examined the effect of vegetarian diets on intermediate risk factors of cardiovascular diseases (Table 1). In a meta-analysis of RCTs, Wang et al. (22) found vegetarian diets to significantly lower blood concentrations of total, LDL, HDL, and non-HDL cholesterol relative to a range of omnivorous control diets. Other meta-analyses have found vegetarian diets to lower blood pressure, enhance weight loss, and improve glycemic control to greater extent than omnivorous comparison diets (23-25). Taken together, the beneficial effects of such diets on established proximal determinants of cardiovascular diseases found in RCTs, and their inverse associations with hard cardiovascular endpoints found in prospective cohort studies provide strong support for the adoption of healthful plant-based diets for cardiovascular disease prevention
