According to Laura Flores, a San Diego-based nutritionist, sweet potatoes are high in vitamin A, vitamin B5, B6, thiamin, niacin, riboflavin, and, due to their orange color, are high in carotenoids.
Findings from latest research have also shown that sweet potato contains a low glycemic index and can help reduce the level of blood sugar and insulin resistance in diabetes patient, as the magnesium in the purple-peel plant can help to control the level of our blood sugar in our blood.
In addition, sweet potato has been shown to have an unusual ability to raise our blood levels of vitamin A and was found to contain between 100-1,600 micrograms (RAE) of vitamin A in every 3.5 ounces. (Enough, on average, to meet 35% of all vitamin A needs, and in many cases enough to meet over 90% of vitamin A needs).
However, it is important to note that some of the nutritional benefits from sweet potatoes maybe achieved with ease if you use steaming or boiling as your cooking method.
Recent studies show excellent preservation of sweet potato anthocyanins with steaming, and several studies comparing boiling to roasting have shown better blood sugar effects (including the achievement of a lower glycemic index, or GI value) with boiling.
With that being said, read on to see some of the mind-blowing health benefits of sweet potato.
