Can One Sweet Potato Give 400% of Daily Vitamin A?
Sweet potatoes are a type of vegetable that grows in the ground.
They are full of something called beta-carotene, which gives them their orange colour.
Our bodies can turn beta-carotene into vitamin A, a nutrient we need to stay healthy.
Just one medium sweet potato can give an adult more than the whole day's amount of vitamin A. Vitamin A helps our eyes see well, keeps our skin healthy, and helps our bodies fight germs.
Sweet potatoes come in different colours, like orange, purple, and white.
Orange sweet potatoes have the most vitamin A, and white ones have the least.
It is almost impossible to get too much vitamin A from sweet potatoes, but eating too many might upset your tummy because of fibre.
Baking, steaming, or roasting sweet potatoes keeps their nutrients, and they taste good with healthy fats.
A medium-sized sweet potato provides 961 mcg RAE of vitamin A, more than 100% of the daily requirement for most adults.
Sweet potatoes are dense in beta-carotene, a provitamin that the body converts into vitamin A as needed.
Among varieties, orange sweet potatoes have the highest vitamin A content, white varieties the least, and purple varieties contain anthocyanins.
The article closes by crediting purple sweet potatoes with about 400% of the daily vitamin A requirement, despite earlier stating purple varieties have low vitamin A compared with orange ones.
Vitamin A from sweet potatoes supports eye health, immunity, skin, and reproductive health, and toxicity from the vegetable is extremely rare.
