Follow one vegetarian diet is associated with a reduction of up to 22% in the risk of suffering Colorectal cancer , according to new research.
The study of University of Loma Linda in California, it also reveals that vegetarians that only eat fish meat and other sea animals, they presented 43% less likely to suffer this type of Cancer , compared to those who are omnivores.
Less meat, more health
The study involved more than 77,000 people, who were followed up by the scientists for seven years. More than half were classified as omnivores , and the others were divided into 4 groups, explains Michael Orlich , lead author and assistant professor of medicine at the institution.
The semi vegetarians, who ate meat less than once a week; vegetarians who consumed fish and other seafood, but avoided other meats; the lacto-ovo-vegetarians, who evaded meat but ate eggs or dairy; and the complete vegans, "he adds.
The results indicate that the vegetarians together they presented a 22% reduction in the risk of suffering Colorectal cancer , compared to the omnivores. Individually, that's equivalent to 19% less risk of colon cancer and 29% less rectal.
The vegetarians who consumed fish and seafood, they had 43% less risk of suffering from omnivores Colorectal cancer . While in vegans and lacto-ovo-vegetarians the probability was reduced from 16 to 18%, and in semi-vegetarians only 8%.
Although the study does not show that the vegetarian diet is the cause of this minor risk, it is associated, Edward Giovannucci , professor of nutrition and epidemiology of the Harvard School of Public Health , states that:
These dietary patterns can decrease the growth factors of insulin and similar substances, hormones that are related to colorectal cancer, compared to the traditional diet that includes red meat. "
For their part, the scientists point out that the Omega-3 fatty acids, potent anti-inflammatory and anticancer , are the key to low risk in the Pescetarian group. In addition, fish provides vitamin D, whose high dose is associated with less risk of suffering Colorectal cancer .
The Colorectal cancer is the second cause of death from tumors in the United States, so the National Cancer Institute recommends colonoscopies for adults over 50, with follow-up every 10 years.
