Diet Rich In Whole Grains Protects Against Liver Cancer

According to a recent study report, the researchers found that a diet rich in whole grains protects against liver cancer by reducing the risks of developing this form of cancer by 40%. However, a higher intake of fruits and vegetables with a high content of fibers do not have the same beneficial effects, according to US scientists.

In recent research, those participants who ate whole grains, regularly, presented a lower risk of developing liver cancer by 40%. On the other hand, diets rich in bran reduce liver cancer risks by 30 percent, while germ lowers the risks by 11 percent. The study was conducted on 77,241 women and 48,214 men in their 50s and 60s throughout a follow-up period of 24 years.

According to the study, a diet rich in whole grains reduces insulin resistance, hyperinsulinemia, and inflammation, all of which are known causes of cancer. The results of the research might prove useful in preventing liver cancer, a disease that affects more than 40,000 Americans each year.

Diet Rich In Whole Grains Protects Against Liver Cancer

“Increased intake of whole grains and possibly cereal fiber and bran could be associated with reduced risk of HCC [hepatocellular carcinoma] among adults in the United States,” said Dr. Xuehong Zhang from Harvard Medical School.

“Whole grains are a major source of dietary fiber and consist of bran, germ, and endosperm, compared with refined grains that contain only the endosperm. The whole grains are good sources of dietary fiber, vitamins, minerals, phytonutrients, and other numerous nutrients, which are removed during the refining process,” explained Zhang.

“Consumption of whole grains and dietary fiber, especially cereal fiber, has been associated with lower risk of obesity, type 2 diabetes, and nonalcoholic fatty liver disease, which are known predisposing factors for [liver cancer]. In addition to improving insulin sensitivity and metabolic regulation and decreasing systemic inflammation, intake of whole grains and dietary fiber may improve gut integrity and alter gut microbiota composition, thereby leading to increased production of microbiota-related metabolites, including short-chain fatty acids, particularly butyrate,” concluded Dr. Xuehong Zhang.
