So how many nuts are too many nuts? According to Healthline, although selenium in small amounts is beneficial, too much selenium can become toxic and begin to have adverse effects on the human body. While a little can go a long way when it comes to Brazil nuts and the selenium they contain, eating too many Brazil nuts at one time can be dangerous and harmful to your health. Selenium, which can be found in Brazil nuts and on the periodic table, ensures a healthy thyroid gland and therefore improves the immune system. Brazil nuts are one of the highest natural sources of selenium: they contain 1,917 µg of selenium in 100 g.
Brazil nuts are actually very healthy for you and introduce a lot of essential nutrients into your body. In recent years, large, bulky nuts from Brazil have slowly but surely been introduced to the American palette. But did you know that these seemingly harmless and unpretentious nuts can actually endanger your health? Nuts for Life is funded by the Hort Frontiers & Food Security Fund for Health and Nutrition, which is part of the Hort Frontiers strategic partnership initiative developed by Hort Innovation, with co-investment from the nut industry and contributions from the Australian Government. Studies conducted on native populations in the Brazilian Amazon region have found blood levels of selenium ranging from 103 to 1500 µg with no signs or symptoms of selenium toxicity.
The tree produces comparatively large hard shell fruits that look like coconuts and contain 10 to 24 edible seeds. There is no doubt that brown rice has a desirable nutritional profile, but one should not live on it. In fact, the FDA advises us not to consume it more than twice a week, in addition to recommending that we cook brown rice in six times the normal amount of water to reduce arsenic levels by half. However, due to gaps in the test suite, a safety factor is applied, resulting in an upper limit of 400 µg (equivalent to 21 g or approximately seven Brazil nuts).
You can find them in the aisles of Trader Joe's jam-packed bundles of mixed nuts and in the elaborate acai bowls at your favorite breakfast cafe. In the case of Brazil nuts and their selenium content, it is recommended that adults eat no more than 5 nuts at a time, as this will reach the maximum amount of selenium they should consume.
