Foods to Increase Your Child's Immune System

Last update: 11 August, 2018

There are certain foods that can help naturally boost your children’s immune system. They also protect them against school viruses and allow them to grow up healthy.

Nutritional deficiencies regarding proteins, carbohydrates and healthy fats – such as olive oil, fruits and vegetables rich in vitamins A, C, E and D – cause children to have low defenses and not be able to counteract diseases.

With this in mind, we’ll provide you with a complete list of foods to increase your child’s immune system. We’ve also included some very effective and simple recipes.

A balanced diet

Eating a balanced and healthy diet ensures that children have an excellent state of health. Their immune system will be able to effectively fight diseases, especially common viruses going around at school.

When talking about a balanced diet, nutritionists say that consuming all food groups is imperative. Of course, exceptions will be present in children who have particular pathologies, food allergies or food intolerances.

However, a frequently asked question is: what happens to children’s immune systems when they aren’t getting enough nutrients in their diet?

Lack of protein

When children don’t eat enough protein – found in meat, chicken and fish – they show a decrease in the formation of lymphocytes. These are responsible for the optimal functioning of the immune system.

Lack of carbohydrates

Carbohydrates are present in products such as rice, pasta, flour, cereals and potatoes. These foods are responsible for providing energy, so they’re necessary for the body’s defenses.

Lack of fat

When nutritionists recommend that children eat fat, they always clarify the type of fat they can ingest. While the absence of a certain food can harm children’s immune system, eating a poor-quality product can also threaten them. 

This is what happens regarding fats. If the child eats saturated fats that come from pastries, sausages or trans fat, there will be an almost immediate and considerable decrease in the child’s immune system.

The only fats recommended for children are those containing omega 3. This is found in olive oil or in fruits such as avocado.

Lack of vitamins from fruits and vegetables

Of all the food groups, the one that provides the most vitamins and minerals are fruits and vegetables. When a child doesn’t ingest them in a large enough amount, his or her health is affected in all aspects, and the immune system cells are oxidized.

While the lack of a certain food can harm children’s immune systems, eating a poor-quality product can also threaten them.
