A research study found that eating a handful of walnuts on a regular basis may reduce women’s risk of developing breast cancer. Researchers from the Marshall University observed in mice that consuming 2 ounces of walnuts each day reduced the growth of breast cancer tumors.
More specifically, they compared the risk of breast cancer among two groups of mice, one group with a regular diet and one group with walnut component of diet. In conclusion, the mice who ate walnuts everyday developed breast cancer at half the rate of the normal diet mice. The tumor size and number of the mice with the walnut diet were smaller and fewer than the mice with the normal diet.
As a result, it appears that walnuts reduce the risk of breast cancer. Additionally, walnuts are rich in omega-3 fatty acids, antioxidants and phytosterols, which may be involved in reducing the risk of breast cancer.
