Brazil nuts sometimes scare people away due to their somewhat overwhelming appearance. While they are big and dark and can be intimidating, as far as food goes, they are loaded with minerals, including calcium, iron, copper, magnesium, potassium, and phosphorus. And while Brazil nuts contain high amounts of all these minerals, they are absolutely packed with selenium, an antioxidant that helps filter out free radicals from your system. Selenium is also crucial to maintaining your immune system and regulating your thyroid gland.
Brazil nuts also contain high amounts of zinc, which make them an ideal food for those with acne problems. Zinc, after all, is believed to offer acne relief, as demonstrated in a 2013 French study published in Dermatology, among others. Brazil nuts may offer additional benefits to the skin due to the high amounts of selenium, which triggers the antioxidant glutathione. When this antioxidant gets to work, it helps fight wrinkles and keep skin looking young and healthy.
