Macro partitioning
Adopting a vegetarian or vegan diet is associated with a significantly reduced risk of ischemic heart disease incidence and mortality compared to an omnivorous diet.
If you switch to a vegetarian or vegan diet, you may lower your risk of heart disease by about 25% compared to eating meat. This is based on large observational studies. Ensure your diet is balanced to maintain health.
GoodSupportsHIGH confidence
vegetarian diet was found to be significantly (p < 0.001) associated with the outcome, with a reduced risk of ≥25% (RR 0.75, 95% CI 0.68 to 0.82)... vegan diet conferred a significant reduced risk (≥15%) of incidence from total cancer.
Why this rating
Meta-analysis of prospective cohort studies with large sample sizes (72,298 vegetarians), though risk of bias was moderate-to-high in many studies.
