Fruits And Vegetables That Boost the Immune System

Fruits And Vegetables That Boost the Immune System

All fruits and vegetables provide essential vitamins and minerals. The FDA recommends five to 10 servings a day. Certain fruits and vegetables also offer additional benefits to the human body, including boosting the immune system.

Vegetables in the allium family include garlic, onions, scallions, leeks, chives and shallots. Garlic is the most powerful of the family, though all alliums contain antibacterial and antifungal sulfuric compounds, according to WebMD. Sulfuric compounds and flavonoid phytochemicals even give alliums cancer-fighting properties.

Leafy Greens
Spinach, Swiss chard and mustard, collard and turnip greens all contain vitamin E, which prevents free-radical cell damage. Vitamin E also strengthens cell walls and increases heart health. Most greens, especially kale and spinach, contain vitamin A, which works with vitamin E, making it more powerful. Kale and mustard greens even contain vitamin C, an immunity-boosting vitamin.

The vitamin C in oranges, grapefruit, tangerines, pomelos, citrons, lemons and limes fortifies the immune system by preventing free-radical damage and carcinogens, destroying bacteria, increasing white blood cells and boosting vitamin E. According to WellFX, vitamin C also reduces histamines, which possibly prevents colds.

Berries, especially blueberries, cranberries, gojiberries and raspberries, fight free-radicals, possess anti-viral properties and come packed with phytochemicals, flavonoids and antioxidants, as well as beneficial vitamins.

Prevention is the best medicine, and everyone can benefit from eating immunity-boosting foods. However, diet should not ignore modern medicine. An orange cannot cure pneumonia.
