Sweet potato, Ipomoea batatas / Convolvulaceae
Benefits for the health
The coloration of sweet potatoes is due to the content of carotenoids, reason why farmers are encouraged to cultivate varieties rich in pro-vitamin A carotenoids in countries where there is a deficiency of produce containing vitamin A. Regarding nutrition, sweet potatoes contain around 100 kcal/100 g, mainly thanks to carbohydrates (starch and sugar, 20-25 g/100 g). They are basic food in many populations, contributing to a great extent to the consumption of a great part of nutrients, particularly vitamin C (23 mg/100 g), for which the daily recommended consumption is around 60 mg/day. It is also good for children and widely accepted thanks to its sweet taste.
