The immune system is one of the most important features of the human body. Without it, our bodies would be vulnerable to disease and ailments. The immune system can be strengthened even more through daily supplements and certain foods and drinks. Fruits are very nutritious and are often used as an immune booster to help overcome illness. Here are a few fruits that strengthen the immune system:
Oranges
Oranges are one of the most common fruits to aid in strengthening the body’s immunity. This fruit is packed with Vitamin C, containing over 100% of the daily amount needed. On top of that, its supply of vitamins prevent cell damage, encourages collagen production, and lowers cortisol, a stress hormone. Oranges are super versatile and can come in the form of cut fruit, juices, and other kinds of foods.
Apples
The saying, “an apple a day keeps the doctor away” is totally true! Apples are filled with natural sugars and fiber. What’s surprising is that the nutrition doesn’t come from the inner apple itself. The most nutrition comes from the skin, which contains a plant pigment flavonoid called quercetin. Quercetin not only boosts the immune system, but also reduces inflammation.
Blueberries
Despite being one of the smaller fruits, a handful of blueberries are just as helpful. These tiny fruitlets contain antihistamines, aiding in reducing inflammation and minimizing various sickness symptoms like a runny nose. Also, they are packed full of antioxidants which boost one’s general health.
