Zinc is a trace element in the human body and has important physiological functions. It is mainly found in seafood and animal offal, and the amino acids produced by the decomposition of meat after consumption can also promote the absorption of zinc in the human body, thus improving the absorption and utilization of zinc more efficiently. Generally animal food is the main source way of zinc supplementation, while staple food, eggs, fruits and vegetables contain very low zinc. 1. seafood: the food with the highest zinc content is oyster, other seafood such as sea shells, clams, abalone and sea fish contain zinc. 2. animal liver and lean meat: such as pork liver, lean lamb and lean beef are the main source way of food zinc supplementation. 3. dairy products: dairy products contain relatively low zinc. But the human body has a high absorption rate of zinc in dairy products; 4, dried fruits: common walnuts, cashews, almonds, peanuts, hazelnuts, pistachios, sunflower seeds, etc. contain zinc; 5, staple foods: millet contains relatively high zinc, in addition to oats, barley, buckwheat contain zinc; 6, fruits: fruits contain less zinc, if you must supplement zinc through fruits, zinc-containing fruits include apples, oranges, lemons, oranges, lychees, kiwis, bananas, strawberries, sweet apricots, etc.; 7. Vegetables: such as spinach, carrots, cabbage, leeks, celery contain zinc, but they contain very little zinc. If zinc deficiency is confirmed, the effect of zinc supplementation through food is limited and zinc supplements can be taken if necessary.
