A diet that boosts your immune system is key to maintaining a strong and healthy immune system. The nutrients we consume every day help our body fight viruses, bacteria and other harmful agents. In this article, you will discover how foods can boost your immune system, based on scientific data and practical advice.
How does nutrition help strengthen the immune system?
The relationship between what we eat and our immune system is direct. Our body needs specific nutrients to produce the cells and substances that are part of the natural defenses. In addition, a balanced diet helps fight free radicals, which damage our cells and affect the immune response. Fruits and vegetables are our best friends when it comes to taking care of our immune system, since they are foods that help strengthen it, being natural sources of antioxidants, a property that helps reduce oxidative stress.
On the other hand, unbalanced diets or those with excessive saturated fats and sugars can weaken the immune system, increasing susceptibility to infections. As we said, excess sugar, salt and even caffeine and saturated fats, as well as alcohol consumption and abuse, weaken the immune barrier of the intestine and allow pathogens to enter.
Essential nutrients to boost defenses
Some nutrients play a key role in the immune system. Below, we explain which ones they are and how they contribute to your defenses:
- Vitamin C
A powerful antioxidant that improves the immune system’s ability to fight infections. Found in citrus fruits such as oranges, tangerines and kiwis, as well as vegetables such as peppers and broccoli, taking vitamin C regularly can reduce the duration of colds. - Vitamin D
Helps regulate immune response and prevent respiratory infections. Sources include fatty fish such as salmon and sun exposure. - Zinc
This mineral is key to the production and activation of immune cells. It is found in lean meats, fish, nuts and legumes. - Antioxidants
Nutrients such as vitamin E and flavonoids protect cells from oxidative damage. They are found in red fruits, nuts and spices such as turmeric. - Proteins
Necessary for cell regeneration and antibody production. The best sources include white meat, fish, eggs and legumes.
