nutritional ingredient

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 the combination of tannic acid and calcium salt to form calcium tannic acid will stimulate the stomach, cause human discomfort, and cause vomiting, dizziness, nausea, abdominal pain, diarrhea and other symptoms.

Seafood should be eaten with these fruits at least 2 hours apart.

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.
