Children are in the stage of growth and development in their daily lives. At this time, if they lack some calcium elements, it may lead to poor physical development. Therefore, children’s bodies are prone to deficiencies of calcium, iron, and zinc elements. Therefore, they should eat some beef and eggs, as well as fish and shrimp, appropriately in their daily lives. These foods have a good effect on replenishing calcium, regulating the body, and promoting digestion and absorption.

Foods with a high calcium content include: dairy products, eggs, fish, shellfish, tofu, legumes, sesame paste, pumpkin seeds, etc. (Vitamin D, Vitamin C, lactose, etc. all help in the absorption and utilization of calcium.)

Chicken, beef, fish and shrimp meat, eggs, milk, and tofu are all rich in protein.

Foods rich in iron: Animal liver and other internal organs, beef, lamb, egg yolks, fish, red beans, spinach.

Foods rich in zinc: Oysters and animal liver.

How to prevent a deficiency of trace elements?

Iron: In animal foods, such as liver, animal blood, meats, and fish, the iron is heme iron, also known as ferrous iron, which can be directly absorbed by the intestines. In plant foods, such as grains, fruits, vegetables, legumes, and animal foods like milk and eggs, the iron is non-heme iron, also known as ferric iron, which exists in the form of complexes. The organic part of the complex is protein, amino acids, or organic acids. This type of iron must be separated from the organic acid part under the action of gastric acid to become ferrous ions before it can be absorbed by the intestines. Therefore, iron from animal foods is easier to absorb than that from plant foods. To prevent iron deficiency, animal foods should be the first choice.

Zinc: Animal foods, such as beef, pork, lamb, fish, and oysters, have high zinc content. Plant foods, such as vegetables and flour, have less zinc content and are difficult to absorb.

Copper: The food that contains the most copper is liver, with most seafood products, such as shrimps and crabs, containing a significant amount of copper. Legumes, fruits, and dairy products contain less copper.

Iodine: Since seawater is rich in iodine, seafood naturally contains iodine, with kelp and seaweed having the highest iodine content.

Selenium: Grains, meats, and seafood contain high levels of selenium, and in areas that are not deficient in selenium, the general diet does not lack selenium.

Due to the varying amounts of trace elements in different types of food, to prevent a deficiency of trace elements, one should consume a mixed diet made from a variety of foods and avoid being picky or partial to certain foods.
