7 Powerful Fruits that Boost your Immune System
Many fruits (and vegetables) contain excellent amounts of vitamin C which is a well-known immunity booster because of its antibacterial and anti-inflammatory properties.
Vitamin C also helps keep your skin healthy, ensuring a more protective barrier against infection. 
And, from World’s Healthiest Foods, “Vitamin C is the primary water-soluble antioxidant in the body disarming free radicals and preventing damage in the aqueous environment both inside and outside cells. Inside cells, a potential result of free radical damage to DNA is cancer. Especially in areas of the body where cellular turnover is especially rapid, such as the digestive system, preventing DNA mutations translates into preventing cancer. This is why a good intake of vitamin C is associated with a reduced risk of colon cancer.
Free radical damage to other cellular structures and other molecules can result in painful inflammation, as the body tries to clear out the damaged parts. Vitamin C, which prevents the free radical damage that triggers the inflammatory cascade, is thus also associated with reduced severity of inflammatory conditions, such as asthma, osteoarthritis, and rheumatoid arthritis.” 
These 7 fruits contain high amounts of vitamin C as well as other important vitamins and nutrients. And these fruits can be eaten in a salad, blended in a smoothie, juiced, or just eaten by themselves!
So, if you need to boost your immune system, these 7 powerful fruits will certainly help!
