One particular type of nut has been in the news recently. It is the Brazil Nut They’re a rich source of selenium, a trace mineral that convinces cancer cells to commit suicide and helps cells repair their DNA. A Harvard study of more than 1,000 men with prostate cancer found that those with the highest blood levels of selenium were 48 percent less likely to develop advanced disease over 13 years than men with the lowest levels.
And a dramatic five-year study conducted at Cornell University and the University of Arizona showed that 200 micrograms of selenium daily—the amount in two unshelled Brazil nuts—resulted in 63 percent fewer prostate tumors, 58 percent fewer colorectal cancers, 46 percent fewer lung malignancies, and a 39 percent overall decrease in cancer deaths
I also advocate for patients with the autoimmune disease, Hashimoto’s thyroiditis to have one brazil nut per day for its content of selenium.
