Colorectal cancers are a leading cause of cancer mortality the study in JAMA showed that vegetarian diets are associated with an overall lower incidence of colorectal cancers.
Study revealed interesting patterns.
Vegetarians tended to be older than non vegetarians,have higher education levels,exercise more,use calcium supplements,less likely to have ever smoked,to drink alcohol,to have had a colonoscopy or sigmoidoscopy,to have Diabetes or have been treated for peptic ulcers or to have used statins or aspirin.
Vegetarians had lower BMI,lower intake of fat,saturated fat,higher intake of fiber.
The Pescovegetarians in particular have a much lower risk compared with non vegetarians.
Ther may be a possible protective association for fish consumption and rectal cancer.
This article I read also proved that vegetarian not only reduces risk of colon. Cancer but even evidence of potential reduced risk of obesity,hypertension,diabetes and overall mortality.
