7 Foods to Boost Your Immune System
Maybe strengthening your immune system only crosses your mind in the winter. However, you need a strong, healthy immune system all year round. Along with staying away from stress and sleeping better, what you eat plays an important role.
As a study published in The American Journal of Clinical Nutrition states, nutrition is critical to immune responses, while malnutrition and obesity reduce immunity. In this article, we’ll tell you about the foods you should add to your diet to keep your immune system in top shape.
Food and your immune system
The food you eat has a big impact on your immune system, for better or for worse. If you eat a diet that’s too high in refined flour, fat, and sugar, your body’s defenses are probably weak, allowing viruses and bacteria in.
On the other hand, if you eat healthy foods like in-season fruit or vegetables, your body will be preparing itself to fight illness-producing microorganisms. Besides controlling your weight, eating less fat will make your immune system function better.
According to information published in the European Journal of Clinical Nutrition, some of the essential nutrients to boost defenses are:
- Vitamin C
- Vitamin E
- Folic acid
- Vitamin B6
- B12 vitamin
- Fatty acids
- Vitamin A or beta carotene

In a study published in Food Science & Nutrition, royal jelly showed positive immunomodulatory effects. It specifically helps to induce an effective immune response of the intestinal mucosa.

Your grandmother has probably told you to drink ginger tea to help with the symptoms of the flu or nasal congestion. She wasn’t wrong!
This root is often used in Asian gastronomy, and it’s very good for you. This is why ginger has been a part of natural medicine for centuries and is recommended to boost the immune system.
According to the journal Herbal Medicine: Biomolecular and Clinical Aspects, ginger fights infections and improves cellular health due to its antioxidants and anti-inflammatory effects.
To reap the benefits of this root, you can sprinkle it in your meals or make a ginger infusion.

Propolis for the immune system
Propolis is a food that’s very high in amino acids, vitamins, essential oils, and bioflavonoids. Although more evidence is needed, a recent study published in the Journal of Family & Community Medicine found that this ingredient, alone or combined with others, can improve immune response and induces immunomodulation.
- Propolis is recommended in cases of frequent respiratory conditions or when your defenses are low due to a certain situation (it can be a family problem, a lot of stress, depression, etc.) and you’re more vulnerable to getting sick.
Yogurt contains different “good bacteria” in charge of regulating intestinal flora while also protecting your immune system. According to a study published in Current Opinions in Gastroenterology, this and other probiotics have shown beneficial effects in the prevention of various diseases.
