1 Nutritionists say that seafood can provide high-quality protein, polyunsaturated fatty acids, vitamins such as vitamin A, vitamin D, vitamin E, riboflavin and nicotinic acid, and minerals such as calcium, phosphorus, selenium, magnesium, iron and zinc. Middle-aged and elderly people, especially women, should eat more seafood. Unsaturated fatty acids in seafood can reduce low-density cholesterol in blood and resist blood coagulation, thus reducing the chances of coronary heart disease, hypertension and stroke in the elderly. Experts believe that pregnant women and lactating women should eat less seafood, up to1-2 times a week, each time100g or less, and do not eat tuna, swordfish and other marine fish with high mercury content.

The disadvantages of eating seafood:

First: affect the quality of male sperm. Because modern marine pollution is serious, the content of heavy metals in seafood is generally high, and the human body ingests more heavy metals, which will reduce the number of sperm in the body, and the accumulation of heavy metals in the body will also cause great losses.

Second: the development of the fetus or newborn is affected. Because of marine pollution, the content of heavy metals in seafood is generally high. If pregnant women or lactating women eat it, it will indirectly affect the development of young children. Therefore, lactating women and pregnant women should eat less or not eat seafood.

Third: it is easy to cause damage to the spleen and stomach. Seafood is only suitable for occasional consumption. If eaten in large quantities, it will cause great damage to people's stomach and intestines. Because seafood is cold, if eaten too much, symptoms such as allergies and diarrhea will occur.
