One thing most doctors and nutritionists would tell you: Eating right is important but it's not nearly enough. In fact, one of the first things they would recommend you do is to improve your diet by including a good variety of all-natural, vitamin-rich foods and supplements that improve your immune system, cleanse your system, and help you fight off infection. In addition, you should make sure that you are getting plenty of exercise (at least 30 minutes daily) and cutting out smoking, stress, drinking alcohol and reducing your use of any medications that could negatively affect your immune system.
Of all the fruits and vegetables on which to build your nutritious diet, oranges have been proven to contain the richest amounts of antioxidants - specifically Vitamin C - of any fruit or vegetable. And just like any other vitamin, citrus fruits are also beneficial to your overall health because they are packed with powerful antioxidants that fight off free radicals and diseases such as cancer, heart disease, Alzheimer's, arthritis, depression, high cholesterol, and even diabetes. So what's the reason for this? Well, citrus fruits have been shown to help fight infection by cleansing the digestive tract, neutralizing free radicals, and preventing inflammation from common diseases like asthma and diabetes.
Orange juice is also rich in powerful immune system booster foods. There are many different orange juice benefits. For one thing, citrus juices are naturally very sweet, so some orange juice drinks can actually provide a mild form of energy and is a great boost to your metabolism. Citrus juices also have ingredients like beta-carotene that help boost the body's immune system. However, the best way to get maximum benefits from orange juice is to use freshly squeezed oranges. You should refrain from using citrus juices that have been processed as those foods lose more vitamins and nutrients than when they are fresh.
