Did you know Sweet Potatoes are loaded with Vitamin A?
Vitamin A is a fat soluble vitamin. Vitamin A deficiency can cause a multitude of issues including- Night blindness, xerophthalmia- dry eyes, keratomalacia- softening and ulceration of the cornea of the eye, Bitot spots- buildup of keratin on the conjunctiva, or follicular hyperkeratosis- blockages of the hair follicles. Vitamin A is also important for eye function, reproduction, skin health, bone growth, and immune function.
There are 2 forms of Vitamin A- provitamin A carotenoids and preformed vitamin A. Provitamin A carotenoids are found in plants (green leafy vegetables, sweet potatoes and carrots). These are metabolized by mammals into Vitamin A. The most common form of provitamin A is beta-carotene. Preformed vitamin A is the most active form of Vitamin A and is found in animal sources (liver, kidney, egg yolk, butter) or supplements. Preformed vitamin A is called retinol.
Vitamin A is an important fat soluble vitamin, it’s vital for optimal health, but you can have too much of a good thing. You CAN overdose on Vitamin A and cause toxicity. This usually occurs from over-supplementation of synthetic preformed Vitamin A. It is very unlikely to overdose on provitamin A carotenoids from plants because it's highly regulated. You may even literally turn orange from eating an abundance of beta-carotene, but not suffer from Vitamin A toxicity. It is recommended that men consume 900 micrograms Vitamin A daily and females should consume 700 micrograms Vitamin A daily.
So again, sweet potatoes are a great source of provitamin A carotenoids. I hope you try these twice baked sweet potatoes! Enjoy!
