✵2. Promote gastrointestinal peristalsis: the purple potato contains a lot of cellulose, it will increase the volume of stools, thus accelerate the peristalsis of the stomach, mucus in the intestine of and corruption material will be out of the body, which contains some toxic and carcinogenic substances, thereby make defecate unobstructed, the intestinal environment can be improved, prevent the occurrence of gastrointestinal diseases.

Nutritional value of purple potato.
✵1. High levels of selenium and zinc, antioxidant, cancer prevention: The content of selenium and zinc in purple potato is 3 ~ 8 times higher than that of sweet potato, which is the key to its ranking in the list of anti-cancer foods. Selenium is an essential component of some antioxidant enzymes, which can prevent cancer. By eliminating lipid peroxides and blocking the pathogenic effects of reactive oxygen species and free radicals, we can delay aging, prevent the occurrence of some chronic diseases, and have an anti-AIDS effect.
Zinc is also a component or activator of many antioxidant enzymes, which can prevent the damage to free radicals and maintain normal immune function. Zinc can also maintain the stability of cell membranes, reducing the absorption of toxins and tissue damage. Zinc plays a regulatory role in tissue metabolism, regulating protein synthesis and metabolism, regulating immune function, and regulating hormones. For example, zinc is involved in the synthesis and release of insulin and the secretion of prostaglandins. Zinc is also essential for DNA synthesis and is involved in the division and proliferation of all cells, promoting growth and tissue regeneration.
✵2. Rich potassium and iron, oxygen for the body, stable blood pressure: In addition to the nutritional advantages of general tubers, purple potatoes are rich in micronutrients such as potassium and iron, which significantly improve their health effects. It is very important for modern people to prevent and cure chronic noncommunicable diseases. Potassium is one of the most important nutrients in the human body and plays a vital role in maintaining the normal metabolism of sugar and protein. Meanwhile, potassium plays an indispensable role in the process of stabilizing blood pressure due to its functions of relaxing blood vessels and promoting sodium excretion. Iron is involved in the formation and maturation of cells in the body to maintain normal hematopoietic function. Iron binds to proteins in the body to form hemoglobin and myoglobin; Delivers oxygen to the body's tissues and viscera.
✵3. Rich in anthocyanins prevent many diseases: Anthocyanins have high health benefits and no side effects. Purple potatoes get their color from anthocyanins, which are naturally powerful free radical scavenging agents(natural antioxidant). Numerous studies have confirmed that anthocyanins have preventive and therapeutic effects on more than 100 diseases, and their ability to scavenging free radicals is 20 times that of vitamin C and 50 times that of vitamin E. Anthocyanins protect brain tissue by clearing free radicals through the blood-brain barrier and reduce the side effects of antibiotics.
✵4. High content of cellulose, promote digestion: Purple sweet potato has a high content of cellulose, which can increase the volume of feces, promote gastrointestinal motility, clean up the stuck mucus, gas and decaying substances in the intestinal cavity, discharge toxic substances and carcinogenic substances in feces, maintain smooth defecation, improve the environment of digestive tract, and prevent the occurrence of gastrointestinal diseases.
