Apples have the highest zinc content among fruits. Foods with high zinc content: lean beef, lean pork, yellow croaker, peanuts, lychees, etc. The raw grains of other cereals are also high in zinc, but they are high in phytic acid, which must be fermented before they can be absorbed and utilized (e.g., steamed cornmeal buns, evaporated cakes, glutinous rice wine, sesame paste, etc. can be eaten).

The main sources of zinc are foods rich in zinc, such as oysters, animal livers, peanuts, fish, eggs, milk, meat and fruits.

Myopia patients are generally deficient in zinc and chromium. Soybeans, oatmeal, almonds, seaweed, kelp, mutton, steak, yellow croaker, sea anchovies, oysters, milk powder, cocoa powder, tea, etc. contain more zinc; Yeast, beef, cereals, meat, liver and cheese contain more chromium.

Animal foods not only have a high content of zinc, but also have a higher absorption rate than plant foods. For example, the absorption rate of zinc in meat is as high as 30~40%, while the absorption rate of plant foods is generally only 10~ 20%. Various beans and nuts in plant foods contain more zinc, and vegetables such as Chinese cabbage, white radish, purple radish, and eggplant contain higher amounts of zinc.

Brown rice has a high zinc content, but if it is processed too finely, a large amount of zinc will be lost. This is because zinc mainly exists in the embryo and husk. Therefore, it is not advisable to eat refined rice and noodles for a long time to prevent zinc deficiency
