1. They can reduce the risk of breast cancer
Eating walnut halves daily provides antioxidants and phytosterols that may help reduce the risk of breast cancer, according to a study at the Marshall University School of Medicine in West Virginia. Mice were fed a daily diet with the human equivalent of two ounces (60 g) of walnuts. Compared to mice fed a control diet, the walnut eaters had significantly decreased breast tumor incidence and a slower rate of tumor growth.
2. They’re packed with omega-3 fatty acids
A diet rich in omega-3s is beneficial in reducing depression, attention-deficit hyperactivity disorder (ADHD), cancer and Alzheimer’s disease and there’s also strong evidence that omega-3s counter inflammatory diseases such as rheumatoid arthritis and Crown’s disease.
3. They can reduce risk of diabetes
Women who reported eating one ounce (30 g) of nuts at least five times per week reduced their risk of type 2 diabetes by almost 30 percent compared to those who rarely or never ate nuts, say researchers at the Harvard School of Public Health. The mono- and polyunsaturated fats in nuts are good for insulin sensitivity.
4. They contain antioxidants that boost heart health
A new study from the University of Scranton in Pennsylvania shows walnuts have higher quality antioxidants and a mix of more healthful antioxidants than any other nut.
