What fruits are good for immunity

Various reasons can lead to a weakened immune system. But most often the body's protective barrier is reduced due to a deficiency of vitamins A, B, E, C. These substances, necessary for strengthening the immune resource of any person, are found in large quantities in fresh fruits, berries and vegetables. Therefore, to restore the normal balance of substances in the body it is enough to add fruits to the daily menu. But it is in this question that most consumers have difficulties, because everyone wants to know which fruits bring more health benefits. Let's try to understand the twists and turns of this question.

The role of fruit in the formation of the immune system

It should be noted immediately that absolutely all the gifts of nature are beneficial to the human body. This property of fruits was known in antiquity, and modern scientists have proven their positive effect on the immune system through clinical studies. But the fact is that this group of products does not act directly on the human defense system, but indirectly. It is known that the main task of the immune system is the ability to respond to any foreign stimulus by activating special cells (lymphocytes). To reproduce these important structures we need "building" material, i.e. vitamins, mineral elements.

Since almost all fruits contain such substances in large quantities, they are considered a valuable source of nutrition for cells working for the immune system. Therefore, to say that any type of fruit works better in this area would be wrong. In the daily diet of a person should necessarily be fresh fruits, which will ensure good health and strong immunity.

What fruits increase immunity

We have already said that any fruit is good for the health of adults and children. But if you dig a little deeper into this question, then the most valuable precisely for the immune system are products that are high in the following vitamins:

1. Retinol (vitamin A) is famous for its powerful antioxidant activity. This substance cleanses cells from free radicals and helps phagocytes to fight against foreign structures, including bacteria, viruses and other pathogens. The following fruits are rich in vitamin A content: peaches, plums and persimmons.
2. Ascorbic acid is the unchallenged leader of all vitamin rankings. The substance also has antioxidant properties, stimulates the synthesis of collagen, that is, rejuvenates the cells of the body. But the main advantage of this vitamin is that it is involved in the production of antibodies. The human body alone can not synthesize vitamin C, so it is very important to include in your diet such fruits: kiwi and lemons.
3. Vitamin B group is involved in the formation of antibodies, so it has a strengthening effect on the immune system. Fruits mainly contain thiamine (vitamin B1) and riboflavin (B2). Bananas and oranges contain the most of these substances.
4. Fiber also plays a significant role in strengthening the immune system, because it ensures the rapid removal of toxins from the body. It is abundant in apples and all citrus fruits.
5. Phytoncides in fruits and berries also provide immune protection, creating a barrier to fungal flora and bacteria. Grapes have plenty of them.
