Compared to omnivores, vegetarians, which include fish, have a lower risk of colorectal cancer, according to a large study in a cohort of Seventh-day Adventists.
The second deadliest cancer in the United States, colorectal cancer is influenced by nutritional factors. Researchers at Loma Linda University in California conducted a study of 77,659 Seventh-day Adventist men and women. Among these participants, the authors distinguished different types of vegetarian diets, and compared them to the diet of omnivores.
Up to – 43% risk
The results show that vegetarians, all types combined, have a 22% reduced risk of colorectal cancer compared to omnivores. And this varies according to the type of vegetarianism: the semi-vegetarian sees his risk of colorectal cancer reduced by 8%, the vegan by 16%, the lacto-ovo vegetarian by 18% and the reduction even reaches 43% for the pesco-vegetarian .
vegetables and fish
These results indicate that vegetarianism, in all its forms, is associated with a reduced risk of colorectal cancer, with particularly interesting results for pesco-vegetarianism. The diet therefore benefits from having a strong vegetable component, but it looks even better with the presence of fish.
