Eating walnuts allegedly gives the body the essential fatty acids omega-3, anti-oxidants and phytosterols, substances that reduce the risk of breast cancer, according to a study presented at the Annual Meeting 100 2009 American Association for Cancer Research.
Phytosterol (which also called plant sterols) are a group of steroid alcohol, phytochemicals naturally found in plants.
Phytosterol-shaped white powder with a distinctive aroma that does not sting does not dissolve in water and soluble in alcohol. The substance 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 although the studies conducted on laboratory animals and not humans, people should pay attention to suggestions for eating more walnuts.
"Walnuts are better than cake, fresh fruit, or potato chips when you need a snack," said Hardman.
Hardman and his colleagues study the 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.
Examination showed standard walnut consumption is noticeably lower incident breast tumors, the number of gland tumors and tumor size.
"This laboratory mice in particular have 100% of the tumor within 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 a decrease in the tumor, but some other part of walnut also gave donations.
"With the intervention of food, you 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."
