Vitamin C

It is one of the ingredients with the greatest nutritional value for the body's natural defenses. In fact, the lack of this vitamin is directly linked to vulnerability to infections. You will find vitamin C in orange, grapefruit, tangerine, strawberry, sweet red pepper, spinach, kale and broccoli. Remember that you have to take vitamin C daily through your diet, as your body cannot synthesize it on its own.

Vitamin B6

It supports the biochemical reactions involved in the immune response. Some of the foods with the highest concentration of vitamin B6 are chicken, green vegetables and chickpeas.

Vitamin E

It has a strong antioxidant effect and helps the body fight infections. Foods rich in vitamin E are nuts, seeds and spinach.

Of course, hydration also plays an important role in the function of the immune system, so in combination with the above foods, make sure you drink enough water during your day!
