Wei Zi hurts when she cuts her nails.

What happened to your nails? I don't know.

But I know what trace elements are: there are many kinds of trace elements, such as iron, zinc, magnesium, iodine and so on.

How to get these elements:

Iron deficiency: You can eat some black fungus, laver, animal liver, day lily, mushrooms, rape, sesame and so on.

Zinc deficiency: you can eat some fish, lean pork, beef, mutton, animal liver and kidney, eggs, dairy products, peanuts, sesame seeds, bean products, walnuts and so on. In severe cases, zinc supplements such as Nixibao can be taken.

Magnesium deficiency: you can eat kelp, seaweed, sesame, soybean, corn, spinach, day lily, black dates, bananas, pineapples and so on.

Iodine deficiency: you can eat kelp, seaweed, sea fish, sea shrimp and so on.
