Foods That Boost The Immune System

Yogurt/Kelfir-Packs a healthy dose of good bacteria that can protect the body against harmful bacteria and infections.

Turmeric- It is found in every yellow curry, and its golden color is the result of curcumin, a polyphenol with strong cold and flu-fighting properties.

Garlic- Much of the immune-boosting properties of garlic come from its sulfur-containing compounds, which also give the bulb its aroma, particularly one called allicin. These compounds are effective against bacterial, viral, fungal and parasitic infections. They also enhance the immune system and have anti-tumor and antioxidant features, which help guard cells from everyday wear and tear.

Oregano- The antioxidant activity in oregano is due to its high content of phenolic acids and flavonoids, color compounds that are also anti-inflammatory. When eaten, oregano can protect against the common cold, influenza, fevers and indigestion.

Red Bell Peppers- Bell peppers are both low in calories and dense in nutrients. They are a good source of phytochemicals as well as beta carotenes and vitamin C.

Green Tea- Tea is rich in polyphenols -- plant antioxidants -- as well as a number of other chemicals that can help protect the body against cold or flu.

Pumpkins-Their rich, orange flesh is packed with beta carotene, a nutrient that the body breaks down to make vitamin A.

Ginger- Ginger has also been shown to reduce nausea and vomiting, making it a very useful food to have around when you have the flu.

Oysters- Has a great amount of zinc. Zinc enhances the function of helper T cells, which are important in identifying foreign antigens and alerting other cells of the immune system to invaders. Even a mild zinc deficiency can have adverse effects on the immune system, particularly in children and the elderly.

Broccli- Excellent source of vitamins A, C and E. In addition, broccoli is high in glucosinolates which stimulate the body's immune system. Broccoli is a powerful food because of its high concentration of sulforaphanes, which are potent anti-cancer agents.
