We updated our article on Type 2 Diabetes and Vegan Diets with a 2019 study of the EPIC-Oxford cohort examing the association between vegetarianism and risk of hospitalization or death from diabetes.
Compared with regular meat-eaters and after adjusting for age, ethnicity, education level, material deprivation, smoking, alcohol, and physical activity, vegetarians (n=13,645) and vegans (n=1,781) had a lower risk of developing diabetes over a mean of 17.6 years of follow-up (HR 0.65, CI 0.55-0.76 for vegetarians; HR 0.53, CI 0.36-0.79 for vegans). However, when further adjusted for body mass index, the association was attenuated (HR 0.89, CI 0.75-1.05 for vegetarians; HR 0.99, CI 0.66-1.48 for vegans).
