Eating walnuts allegedly gives the body the essential fatty acids omega-3, anti-oxidants, and phytosterol, a substance that reduces the risk of breast cancer, according to a study presented at the 100th Annual Meeting The 2009 Association for Cancer Research America.
Phytosterol (also called plant sterols) are a group of steroid alcohol, phytochemicals naturally found in plants.
Phytosterol -shaped white powder with a distinctive aroma that can not sting is not soluble in water and soluble in alcohol. These substances has many benefits, such as food additives to reduce cholesterol levels, as well as in medicines and cosmetics.
Elaine Hardman, assistant professor of medicine at Marshall University School of Medicine ", said that although studies conducted on laboratory animals and not humans, people should pay attention to advice to eat more walnuts.
"Walnuts are better than cake, fresh fruit, or potato chips when you need a snack," said Hardman.
Hardman and his colleagues studying mice that were fed food that they expect the same with the human portion, two ounces of walnuts per day. A separate group of rats were given food that is monitored.
Standard examination showed walnut consumption is noticeably lower incident breast tumors, total gland tumors and tumor size.
"This laboratory mice in particular has a 100% tumor events in five months; walnut consumption inhibits tumor growth until at least three weeks," said Hardman.
Molecular analysis showed, increased consumption of omega-3 fatty acids contribute to the decrease in tumor event, but some other part of walnut also contribute.
"With the intervention of food, you will see many mechanisms when dealing with a whole food," said Hardman. "It is clear that the walnuts contribute to healthy foods that can reduce breast cancer." (ant / cax)
