This list contains all the studies I’ve collected over time. It is not a complete list as the mountain of evidence supporting a vegan lifestyle is huge and growing rapidly.


The British Dietetic Association and the American Dietetic Association, both the largest bodies of nutrition professionals in their countries state that a well-planed vegan diet is safe, healthy and nutritionally adequate for all stages of life including pregnancy. Furthermore the Academy of Nutrition and Dietetics states that 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. 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.

WHO on the cancer risk of meat:  “The consumption of processed meat was associated with small increases in the risk of cancer in the studies reviewed. In those studies, the risk generally increased with the amount of meat consumed. An analysis of data from 10 studies estimated that every 50 gram portion of processed meat eaten daily increases the risk of colorectal cancer by about 18%. The cancer risk related to the consumption of red meat is more difficult to estimate because the evidence that red meat causes cancer is not as strong. However, if the association of red meat and colorectal cancer were proven to be causal, data from the same studies suggest that the risk of colorectal cancer could increase by 17% for every 100 gram portion of red meat eaten daily.” The IARC Working Group, consisting of 22 experts from 10 countries, considered more than 800 different studies on cancer in humans.
