cancer rates among vegans

Vegans (n=753) had a heart disease rate of 0.74 (0.46, 1.21) and a mortality rate of 1.00 (0.70, 1.44). In a 2016 paper from EPIC-Oxford (Appleby, 2016), there was no difference in all cancer mortality between vegetarians (including vegans) and regular meat-eaters (0.93, 0.82-1.05).

A new study just out of Loma Linda University funded by the National Cancer Institute reported that vegans have lower rates of cancer than both meat-eaters and vegetarians. Vegetarians, as shown in Table 20 below, had significantly lower rates of oral cancer in this study of Indian vegetarians. A vegan diet is surely a healthier diet, and scientific studies show that diseases such as diabetes, cardiovascular disease, rheumatism and allergies, also considered chronic diseases, are seen much less in vegans, said cardiology and internal medicine doctor.

Table 1 shows that the 2014 study from EPIC-Oxford is the first to show vegetarians to have a lower cancer rate than non-vegetarians (not including pesco-vegetarians). After excluding participants who changed diet categories during the study, vegetarians had a lower risk of all cancer (0.82, 0.72-0.94), and similar findings as above for the other cancers. Vegans suffered from 67 deaths from cancer, with a rate not significantly different from regular meat-eaters (1.14, 0.88-1.47). 2003 Sep;78(3 Suppl):533S-538S. 2015 Mar 9.

In fact, vegans — those who don't eat any animal products including fish, dairy or eggs — appeared to have the lowest rates of cancer of any diet.

Lifelong vegetarianism and breast cancer risk: a large multicentre case control study in India. When analyzing the association of specific vegetarian dietary patterns, vegan diets showed statistically significant protection for overall cancer incidence (HR, 0.84; 95% CI, 0.72-0.99) in both genders combined and for female-specific cancers (HR, 0.66; 95% CI, 0.47-0.92). In this group of men, vegan diets were the only form of vegetarian diet linked with lower prostate cancer, and this association remained even after adjusting results of the analysis for weight. That study did not adjust for having children which is protective against breast cancer, and vegetarian women tend to have fewer children. Not cited. Nutr Cancer.
