If adults are short of zinc, first consider foods with high zinc content, such as lean beef, pork, mutton, chicken heart, fish, oysters, egg yolk, skim milk powder, wheat germ, sesame seeds, walnuts, beans, peanuts, millet, radish and so on. Zinc mainly exists in marine products and animal offal, and is less in other foods. There is almost no zinc in water, staple food and eggs, and there are not many vegetables and fruits containing zinc. Lean meat, pork liver, fish and egg yolk contain zinc, among which oysters contain the highest zinc.

According to the laboratory test, the zinc content of animal food is generally high, and the zinc content per 100g of animal food is about 3-5mg. The amino acids produced after the decomposition of animal protein can promote the absorption of zinc. Plant food contains less zinc, about 1mg per 100g plant food, while various plant foods such as beans, peanuts, millet, radish and Chinese cabbage contain higher zinc. Of course, zinc deficiency and excessive zinc supplementation will also have a certain impact.

When zinc deficiency is not serious, medicine is not as good as food supplement. Eat more zinc-containing foods such as animal liver, lean meat, egg yolk and fish. There are many health products containing zinc now. Whether it is a developing child, a pregnant mother, a busy white-collar worker, or an elderly person who is not as good as before, they all want to supplement zinc, so various drugs and health products for supplementing zinc are constantly being refurbished. Children or the elderly sell zinc supplements the fastest, accounting for 60-70% of sales, but few people really lack zinc, and most people don't need additional zinc supplements. Excessive zinc supplementation in children can not only promote growth, but also cause poisoning and affect growth and development. Keep normal eating habits, and you won't be short of zinc. Whether zinc is deficient depends on the comprehensive judgment of the doctor.
