Brazil nuts are the richest food in selenium, an essential trace mineral, which is important for hair growth. Just a Brazil nut a day can prevent hair loss, due to selenium deficiency.
Selenium benefits for hair growth
Selenium is an essential trace element. We have to take it from food. Above all, selenium is required for the synthesis of more than 35 proteins. Also, selenium is vital for the synthesis of glutathione peroxidase, a powerful antioxidant enzyme.
Selenium protects your hair as it has antioxidant actions and fights oxidative stress, which is a common cause of hair loss. You can see the whole list of necessary vitamins and minerals for hair growth here.
Brazil nuts are the richest food in selenium
The recommended daily intake of selenium is 55 mcg. Just one Brazil nut contains more than the recommended daily intake, though. A Brazil nut contains 95 mcg of selenium.
Eating too many Brazil nuts is bad for hair growth, though. We shouldn’t consume more than the maximum safe dose. Eating a handful of Brazil nuts (only 6-8 nuts) provides more than the allowable daily intake!
