Eating a handful of walnuts can protect against prostate cancer

Researchers from the School of Medicine at The University of Texas Health Science Center in San Antonio have shown that eating a modest amount of walnuts can protect against prostate cancer (Cancer Investigation).

Chris Woollams covers the benefits of walnuts in his book The Rainbow Diet and how it can help you beat cancer. Walnut trees are common along the Mediterranean.

After giving mice prostate cancer and then providing walnut-rich diets, the numbers protected rose from 18 per cent to 44 per cent. The serving was equivalent to a handful of nuts a day (about 14). At the same time the average tumour size was only a quarter of those in the non-walnut eating group.

Dr. Russell Reiter the lead researchers said, ‘The data to date suggest that using walnuts on a regular basis in the diet may be beneficial to defer, prevent or delay some types of cancer, including breast and prostate’.

Walnuts have high levels of ‘good’ fats and antioxidants and have previously been shown to reduce levels of heart disease, cognitive decline, men’s reproductive health and many forms of cancer while helping to optimize blood lipids and weight management. (
