During recent years the sales of sweet potatoes (also known as yams) have grown by about 20 percent per year. The product is a staple in food magazines, cookbooks and on television shows.
According to the U.S. Food & Drug Administration the orange flesh sweet potato is the only major vegetable that contains four nutrients that exceed 10 percent of the recommended daily amount.
These four nutrients are vitamin A (beta carotene), vitamin C, fiber and potassium.
Researchers at the University of Ulm in Germany recently released a study stating serum concentration of the antioxidants vitamin C and beta carotene were shown to be significantly lower in patients with mild dementia than in control persons. This opens the door to the possibility of influencing Alzheimer’s dementia by a person’s diet or dietary antioxidants.
It also has been reported previoiusl that the orange fleshed sweet potato is the most nutritional fresh produce item on the planet.
The Center for Science in the Public Interest names sweet potatoes the No. 1 most nutritious food because they are loaded with carotenoids, vitamin C, potassium and fiber.
Sweet potatoes also are city as a leading food item in ending world hunger? Apparently, they are. A grassroots advocacy and campaigning organization that fights extreme poverty and preventable disease, particularly in Africa, has a campaign in action now that aims to do just that.
The project demonstrates how, by providing much-needed nutrients like vitamins C, A and B6 to undernourished children, sweet potatoes are helping to avert stunting and ensuring proper growth. In addition, sweet potatoes are cheap to produce and they are easy to grow in uncertain conditions: perfect for regions prone to drought and famine.
