Feeding your body with certain foods may help keep your immune system strong and prevent you from getting infected with diseases. 

A healthful, balanced diet plays a vital role in staying well. The following foods may help to boost the immune system:

1.Ginger 

Upping your intake of antioxidant-rich foods and beverages like ginger shots may combat inflammation and keep your immune system healthy. Many test-tube and animal studies suggest that ginger can enhance immune response. What’s more, ginger has powerful antiviral and antibacterial properties. 

2.Green tea 

One of the beneficial compounds found in green tea has a powerful ability to increase the number of “regulatory T cells” that play a key role in immune function and suppression of autoimmune disease, according to new research in the Linus Pauling Institute at Oregon State University.

3.Turmeric 

Turmeric is a natural way to help bolster the immune system by increasing the immunomodulating capacity of the body. Other benefits such as helping prevent cancers, Alzheimer’s disease or even easing arthritis symptoms will come from turmeric intakes. 

4.Blueberries 

In addition to having plenty of vitamins (vitamin C, vitamin A, potassium, dietary fibre etc.), blueberries contain flavonoids which is a type of antioxidant that may help reduce the damages done to the cells and boost your immune system. Other berries have similar benefits such as cranberries, blackberries and strawberries etc. 

5.Oily fish 

Eating oily fishes such as salmon, herrings or mackerels is associated with many health benefits. It can improve your skin, contribute to preventing heart disease and even support your immune system

6.Citrus fruits 

Oranges and kiwis are an excellent source of vitamin C, which is the vitamin that many people turn to when they feel a cold developing.

7.Red bell peppers 

Red bell peppers are a good alternative if you want to stay away from sugar from fruits but enjoy the benefits of vitamin C they contain. 

Stir fried or roasted is best to keep the nutrients rather than boiling or steaming them as studies confirm.
