Yan'an Sweet Potatoes

Yan'an Sweet Potatoes

　　Sweet potatoes are rich in starch, dietary fiber, carotene, vitamins A, B, C, and E, as well as more than ten kinds of trace elements such as potassium, iron, copper, selenium, and calcium, along with linoleic acid. They are highly nutritious and are regarded by nutritionists as one of the most balanced health foods. These nutrients help maintain vascular elasticity and are very effective in preventing habitual constipation in the elderly. Unfortunately, many people avoid eating sweet potatoes because they believe they can cause weight gain. In fact, the opposite is true: not only do sweet potatoes not lead to weight gain, but they can also aid in weight loss, improve fitness, prevent sub-health conditions, and promote bowel movements and detoxification. Each 100 grams of fresh sweet potato contains only 0.2 grams of fat and provides 99 kilocalories of energy, about one-third that of rice, making it an excellent low-fat, low-calorie food. At the same time, sweet potatoes effectively prevent carbohydrates from turning into fat, which is beneficial for weight loss and fitness. Sweet potatoes are also high in dietary fiber, which cannot be digested or absorbed in the intestines but can stimulate the gut, enhance peristalsis, and aid in bowel movements and detoxification—especially effective against age-related constipation. When eating sweet potatoes, make sure they are thoroughly steamed or boiled. Avoid overeating sweet potatoes, and individuals diagnosed in Traditional Chinese Medicine with dampness obstructing the spleen and stomach or qi stagnation and food stagnation should consume them with caution.
