Fruits, vegetables and fish can greatly lower your risk
Research has shown that what you eat can play a large role in your risk for developing colorectal cancer. A recent study also shows that a diet of mostly fruits, vegetables and a moderate amount of fish appears to offer the most protection against developing colorectal cancer.
The study, published in the journal JAMA Internal Medicine, found a pesco-vegetarian diet — dominated by fruits and vegetables and including a moderate amount of fish — is associated with a 45 percent reduced risk for colorectal cancers compared to people whose diets include meat.
Researchers at Loma Linda University analyzed the diets of nearly 78,000 people and then compared the diets to cancer incidence rates to estimate the number of people who might develop colorectal cancer.
They found vegans had a 16 percent lower risk for all colorectal cancers compared to non-vegetarians. Vegans do not eat any foods derived from animals, including dairy products such as cheese, milk and eggs.
The researchers also found that vegetarians had 22 percent lower risk of colorectal cancer compared to meat-eaters. In general, vegetarians avoid eating meat, but do eat dairy products or certain dairy products such as eggs.
But, the researchers found, the pesco-vegetarian diet appears to offer the most protection against colorectal cancer. A pesco-vegetarian is a vegetarian who also consumes fish and seafood.
