MONDAY, March 9, 2015 (HealthDay News) -- A vegetarian diet might cut your risk of colorectal cancer by 20 percent, a new study finds.

For fish-eating vegetarians, the protective link was even stronger, researchers said.

Colorectal cancer is the second leading cause of cancer death in the United States. Screening efforts, including colonoscopy, have helped save many lives by detecting precancerous polyps, said the study's lead researcher, Dr. Michael Orlich.

"However, it is even better to prevent cancers from forming in the first place. We call this primary prevention," said Orlich, who is an assistant professor of preventive medicine at Loma Linda University in California. "Diet is a potentially important approach to reduce the risk of developing colorectal cancer."

The new study, which involved more than 77,000 adults, found that people consuming healthy vegetarian diets may have a lower risk of colon and rectal cancers than non-vegetarians, Orlich said.

"Our vegetarians not only ate less meat than the non-vegetarians, but also less sweets, snack foods, refined grains and caloric beverages," he said. And they ate more fruits, vegetables, whole grains, beans and nuts, he added.
