The main value of shrimp:
1, shrimp should not be eaten with some fruits. Shrimp is rich in nutrients such as protein and calcium. If fruits containing tannic acid, such as grapes, pomegranates, hawthorn and persimmons, are used for treatment, not only will the nutritional value of protein be reduced, but when tannic acid is combined with calcium salt to form calcium tannic acid, it will also stimulate the stomach and cause human discomfort, with symptoms such as vomiting, dizziness, nausea, abdominal pain and diarrhea. Seafood should be eaten with these fruits at least 2 hours apart.
2. Shrimp skin is rich in calcium, and it also contains an animal fiber called chitin, which is a polysaccharide and cannot be digested and absorbed by human body. After chemical treatment, it can be dissolved in water to make health food chitosan.
3. Shrimp is nutritious, soft and easy to digest, and it is food for people who are weak and need to be nursed back to health after illness.
4. Shrimp is rich in magnesium, which plays an important role in regulating heart activity and protecting cardiovascular system. It can reduce the cholesterol content in blood, prevent arteriosclerosis, dilate coronary artery, and help prevent hypertension and myocardial infarction.
