Benefit: thyroid function

Brazil nut is the richest known source of selenium, containing up to almost 100 times more selenium than most other nuts. Selenium makes it an excellent choice for proper thyroid function, immune system and cell growth. However, while low levels of selenium are linked to neurodegenerative diseases like Parkinson’s and Alzheimer’s, consuming too many brazil nuts on daily basis (more than 5), can lead to selenium toxicity and overdose. Brazil nut is also rich in antioxidants like polyphenols gallic and ellagic acid and vitamin E, fighting inflammation. Finally, it is loaded with healthy polyunsaturated fats, reducing bad cholesterol and keeping heart healthy.
