Brazil Nuts Certified Organic 10 oz. by NOW Foods
Eating one or two Brazil Nuts per day is better than taking a selenium supplement according to researchers. Selenium may reduce the odds of prostate cancer. Selenium boosts one of the body's most important antioxidant enzymes, glutathione peroxidase. This may be of interest to glaucoma patients for offsetting the oxidative stress that underlies glaucoma.

Brazil Nuts may not be as popular as other nuts, but don’t be fooled – these little fellas are packed with just as much nutrition. Native to the Amazonian rain forests of South America, Brazil Nuts are one of the richest known natural food sources of selenium, an important dietary mineral. They’re also a good source of magnesium.

New Zealand researchers compared Brazil nuts' efficacy to that of selenomethionine supplements in increasing selenium status in 59 New Zealand residents with low selenium (plasma selenium concentrations < 1.27 micro mol/L).
Participants were randomly assigned to one of three groups. One group ate two Brazil nuts each day (estimated to provide approx. 100 micrograms Se). A second group took a supplement providing 100 micrograms of selenium as selenomethionine per day, and the third group, who served as controls, were given a placebo pill. Blood levels of selenium and glutathione peroxidase (GPx - a selenium containing enzyme that is one of the body's most important antioxidants) activities were measured at the beginning of the study and at 2, 4, 8, and 12 weeks.
By week 12, blood levels of selenium had increased by 64.2%, 61.0% and 7.6%, respectively, in the Brazil nut, selenomethionine, and placebo groups. Plasma levels of GPx increased by 8.3%, 3.4% and -1.2%, and whole blood GPx by 13.2%, 5.3% and 1.9% in the Brazil nut, selenomethionine and placebo groups, respectively.
Not only was consumption of two Brazil nuts each day as effective for increasing selenium status and enhancing GPx activity as 100 micrograms of selenomethionine per day, but just one Brazil nut per day would have been sufficient to raise dietary selenium intake to within recommended intake levels for the mineral.
The researchers pointed out that food sources are always preferable to supplementation for improving the nutritional status of a population because they are sustainable, less expensive and have a lower risk of toxicity.
The authors did, however, warn that Brazil nuts are not uniform in their selenium content and may contain much more or much less than the estimated 50 micrograms per nut. No more than one or two Brail nuts should be consumed daily to avoid excessive accumulation of selenium in tissues.
Practical Tip: Enjoy just one Brazil nut each day and help ensure that you get your daily requirement for selenium.

NOW Foods is an award-winning and highly respected manufacturer of vitamins, minerals, dietary supplements and natural foods. In 1948, with the natural food and supplement industry in its infancy, entrepreneur Paul Richard paid $900 for the purchase of Fearn Soya Foods—a Chicago based manufacturer of grain and legume-based products. This began a six-decade legacy of providing health-seeking consumers with high-quality, affordable nutrition products.
