9. Pescatarian Diet
When we are talking about a person who follows the pescatarian diet, his/her main source of animal protein is fish or other seafood. Pescatarian diet enthusiasts also consume vegetables, legumes, fruits, whole grains, and other plant-focused foods.
Several studies show that this type of diet is linked to lower overall risk of cancer compared to other diets that include meat and fish more than once a week. As a matter of fact, in a U.S. study, pesco-vegetarians showed a particularly low risk of colorectal cancer, compared to people following other types of vegetarian diets.
“This eating pattern is likely to have higher levels of omega-3 fatty acids (the type of fat found in fish), but so far this type of fat has not been tied to lower cancer risk, so it’s not clear what might explain this association,” Collins says. “Limited evidence suggests a potential association between fish and lower colorectal cancer risk, according to AICR.”
