Five Fruits That May Help to Bolster Your Immune System

As the upcoming cold and flu season quickly approaches, it is the best time to start thinking about new methods to boost immune system functioning and stay healthy this winter. To prevent catching the latest germs going around, be sure to stock up on these five healthy fruits to give your immune system a jump start.  No, they won’t cure what ails you, but they can certainly help you avoid ailments in the first place.

1. Grapefruit

Although grapefruit are commonly associated with weight loss and diets, the citrus fruit is also an exceptional source for boosting the immune system. Just one-half of a grapefruit contains 100 percent of the essential daily value of Vitamin C. Even better, grapefruit are also shockingly low in calories too, with one-half equaling only 60 calories. Grapefruit can be eaten plain with a tad of sweetener, or they can be easily juiced for a refreshing juice beverage.

2. Kiwis

Despite being just 90 calories, two medium-sized kiwis deliver an astonishing 240 percent of the daily value for Vitamin C in your diet. From such a tiny fruit, there are also a whopping 450 milligrams of potassium and four grams of fiber for loads of health benefits. Kiwi is an excellent snack choice to be eaten on its own, diced up in a fruit salad, or sprinkled atop yogurt.

3. Mangosteen

Often referred to as a “super fruit,” the mangosteen has been proven to pack a punch full of healthy benefits. Not only does the tropical fruit help out with Alzheimer’s disease and even acne, it has been correlated to improvements in immune system response in a recent study. It also helps reduce high levels of C-reactive proteins that are indicators of inflammation in the body. Mangosteen is widely found in juice products, like those made by Xango.

4. Strawberries

As yet another powerhouse for the immune system boosting Vitamin C, only eight strawberries provides 160 percent of the needed daily value. In addition, this same amount of strawberries packs 170 milligrams of potassium at just 50 calories. Strawberries can be eaten on their own, or mashed into a sauce to drizzle over a dessert.

5. Blueberries

Recent research findings discovered that blueberries contain Vitamin B and stilbenoids, which are compounds that work with Vitamin D to increase the expression of the CAMP gene. Since this gene plays a vital role in being the first line of defense against bacterial infections, blueberries are considered to be a highly favorable immune system booster. Blueberries can be popped plain or be added to yogurts and cereals.

In order to ensure your body and immune system are protected, round out your diet with a healthy dose of these five colorful and delicious fruits. While it certainly takes more than eating an apple a day to keep the doctor away, eating these immune boosting fruits on a regular basis will help keep your system in top shape for battle.
