According to experts in nutritional immunology, peaches are rich in vitamins, minerals and fruit acids, and their iron content ranks first among fruits. Iron is the main raw material for human hematopoiesis, which is quite beneficial to health. Peach plays an important role in many herbs.

Grape is the fruit with high iron content, and spinach is the vegetable with high iron content. Foods high in iron are animal liver and lean meat, as well as chicken and duck eggs and milk.

Foods rich in iron include animal liver (containing 52 mg of iron per 100 grams) and animal whole blood (containing iron per 100 grams 15 mg). Others, such as meat, mussels, dried shrimps, egg yolk, auricularia auricula (dried), kelp (dried), sesame, sesame paste, soybean, pumpkin seeds, watermelon seeds, celery, amaranth, spinach, leeks, lettuce, millet, red dates, purple grapes, red fruits and cherries, are all rich in iron. If you eat it regularly, you can supplement the iron you need. Secondly, cooking food in an iron pan can also supplement the iron source. It has been determined that in Zhajiang Noodles cooked in glassware,100g of Zhajiang Noodles contains only 3mg of iron; However, the iron content in iron pot cooking is as high as 87.5 mg per100g. Others have done such an experiment. After frying100g onion in an iron pan and heating with oil for 5 minutes, the iron content in the fried onion increased by1~ 2 times. If salt and vinegar are added and heated for 5 minutes, the iron content will increase to15 ~19 times. According to the calculation, in a person's life, he needs to get the iron equivalent to a kitchen knife from food.
