Health & Life Newspaper quoted Traditional Medicine Practitioner Tran Dang Tai - Vice President of the Oriental Medicine Association of Thai Hoa Town - Nghe An as saying that sweet potatoes are rich in fiber and pectin, which can promote intestinal motility, help the digestive tract digest and absorb food better, help the intestines metabolize substances to be eliminated from the body better and prevent constipation.
In addition, for people with potential cardiovascular and cerebrovascular diseases, sweet potatoes are a healthy food. Mucilage protein, trace element potassium and other nutrients in sweet potatoes can remove cholesterol and triglycerides accumulated on blood vessel walls and other impurities, thereby preventing the occurrence of cardiovascular and cerebrovascular diseases.
Although sweet potatoes are good for health, not everyone can eat them. VnExpress newspaper quoted physician Bui Dac Sang, Vietnam Academy of Science and Technology, Hanoi Oriental Medicine Association, saying that the following people should not eat sweet potatoes:
People with kidney disease
Sweet potatoes contain a lot of fiber, potassium, and vitamin A. People with kidney disease have limited ability to eliminate excess potassium, so eating sweet potatoes can cause arrhythmia and heart failure.
Sweet potatoes are good for health but not everyone can eat them.
People with poor digestive system
People with poor digestive systems who eat a lot of sweet potatoes can lead to increased gastric juice secretion, causing heartburn, heartburn, and bloating. Eating sweet potatoes at night can easily cause reflux, especially for people with weak stomachs or the elderly with poor digestion, prone to bloating. In addition, at night, the body's metabolism is often low, so eating sweet potatoes is difficult to digest, leading to insomnia.
To avoid this, you should cook, boil, or grill the food thoroughly or add a little alcohol to destroy the yeast. If you have bloating, you can drink ginger water to cure it.
Notes when eating sweet potatoes
Do not eat persimmons with sweet potatoes. The reason is that when eaten together, the sugar in sweet potatoes ferments in the stomach, causing more gastric juice to be secreted, reacting with the tannin and pectin in persimmons, causing precipitation.
Sweet potatoes contain the same amount of carbohydrates as rice. Therefore, if you eat sweet potatoes, you should reduce the amount of rice to avoid excess starch.
Do not eat sweet potatoes with black spots. If black spots appear, it means that the potatoes are contaminated with bacteria, which will cause liver poisoning. Whether baked or boiled, this toxin is not easily destroyed. Therefore, you should absolutely not eat these contaminated sweet potatoes.
Do not eat sweet potatoes with the skin on, because the skin of sweet potatoes contains a lot of alkaline substances, which will affect the peristalsis of the digestive system.
You should combine green vegetables and fruits, foods in the protein group to ensure a nutritious meal. For example, when eating potatoes, you can add pork to increase absorption, promote absorption of fat-soluble carotenoids and vitamin E. Eating potatoes with some salty dishes can adjust the flavor, good for the stomach.
