Sweet potatoes are delicious, nutritious and easily available that even NASA chooses them for their space missions. Some people consider them super food, which isn’t strange knowing that they contain the most nutrients per dollar value.
Besides being delicious, sweet potatoes are praised for their anti-cancer properties. Almost a century ago, it was found that the vegetable contains a unique protein, which was later discovered to possess anti-cancer properties. In the beginning, the protein was tested against leukemia, and the results showed that it can hinder the growth of leukemia cells in petri dishes.
When proteins enter the stomach, they are immediately digested, so in order to avoid this problem, scientists tested the sweet potatoes’ protein against tongue cancer cells. Tongue cancer patients are usually treated with chemotherapy which has harmful side-effects.
