The Best Superfoods You Can Eat to Strengthen Your Immune System

Health is a matter that affects everyone. Germs do not discriminate based on race, religious preference, or social class. Likewise, the ability to fight diseases and build up the immune system is one that anyone can accomplish. Good hygiene is paramount at staving off germs and bacteria. However, the food that is absorbed by the body may be the best course of preventive action.

Green, Leafy Vegetables

Vitamin C is often touted as a great immune system booster. Citrus fruits are well known to be high in vitamin C. However, leafy green vegetables are high in that vitamin while also being rich in B vitamins, folate, Vitamin E, Vitamin A, and copper. Kale receives much praise for its powerful nutrients. However, there are many other choices that are just as healthy. Try collard greens, turnip greens, Swiss chard, spinach, or romaine lettuce. Watercress is often argued to be the healthiest vegetable of all.

Whole Grains

A gluten-free lifestyle is all the rage, but this new trend could be detrimental to the immune system. While some people must avoid gluten for health reasons, others should stick to a whole grain diet for whole body health. A study on oats, published by the National Institutes of Health found that the beta-glucans in oats lower cholesterol while helping the body stave off disease and infection. Another study on beta-glucans found a link between the absorption of this protein and cancer-fighting properties. Beta-glucan is found in oats, barley, wheat, and rye.


According to Harvard Health Publications, garlic could be an important immune system stimulant. Research shows that garlic fights fungus, bacteria, and viruses. Studies have shown that garlic is high in selenium, a proven friend of the immune system.


Blueberries, elderberries, cranberries: These are all foods that have properties that aid the immune system. Elderberries are commonly used to fight influenza. Blueberries are high in vitamins A and C. They are also full of antioxidants, which may help to prevent cancer. Strawberries are likewise an excellent choice. A berry salad filled with the different all different types may be the best immune system boosting food choice of all.

A healthy, whole foods approach to eating is arguably the best for boosting the immune system. As long as most of the food groups are covered, the body can fight most diseases. The opposite is also true. Avoid foods that are high in saturated fat, sugar, sodium, and unnecessary chemicals to have the healthiest body. Still, eating foods that are known to boost the immune system keeps the body stronger for longer.
