Zinc for Immunity: Unexpected Foods That Cover the Daily Requirement.

Why Zinc Is Important for the Body

According to ТСН: Zinc is one of the key trace elements necessary for supporting the immune system, healing wounds, and normal cellular activity. It can be obtained from everyday foods, some of which may surprise you.

Sources of Zinc

The highest amounts of zinc can be found in oysters and other shellfish. For example, three oysters can provide about 24 mg of zinc, which exceeds the daily requirement. Zinc can also be found in king crab, mussels, and shrimp, though in smaller amounts. The recommended daily intake for adults is 8–11 mg, and for pregnant and nursing women up to 13 mg.

Meat products, including beef, pork, and chicken, are also good sources of this trace element. For example, a serving of beef contains nearly 4 mg of zinc, while a turkey breast has about 1.4 mg. However, plant-based foods can also provide the necessary amount of zinc.

Plant Sources of Zinc

Legumes, such as beans, lentils, peas, peanuts, and soy products, are good sources of zinc and other beneficial substances. Half a cup of cooked lentils or firm tofu contains about 2 mg of zinc. Although legumes contain phytates that reduce the absorption of the trace element, proper cooking—soaking, boiling, or fermenting—can minimize this effect.

Zinc is also found in dairy products. A glass of cow's milk or a slice of cheddar cheese provides about 1 mg of the mineral. As an alternative, soy-based plant drinks are often enriched with zinc.

Nuts and seeds can also increase zinc content in the diet. Hemp seeds, pumpkin or sunflower seeds, as well as almonds contain between 1 to 2.3 mg of zinc per serving. An unexpected source of zinc is dark chocolate: a bar with 70–80% cocoa content contains over 3 mg of this mineral.

Other Sources of Zinc

Small amounts of zinc can be found in whole grain products, such as oatmeal, brown rice, and whole grain bread. Although fruits and vegetables do not contain it in large amounts, potatoes, leafy greens, kiwis, and grapefruits can also contribute.

Experts emphasize the importance of consulting a doctor or nutritionist if your diet does not provide enough zinc. Prolonged self-administration of supplements can be harmful, as excess zinc can interfere with the absorption of other minerals and cause side effects.

It is worth noting that many people are accustomed to leaving a glass of boiled water by their bed at night to drink it in the morning. We reported whether it is really safe to drink water that has been left out for a few hours.
