Prevent Getting Sick by Supporting Your Immune System Naturally

Having a basic understanding of how nutrients support your immune system will help strengthen a healthy lifestyle and may help fight off a cold or flu. Some of the important immunity supporters to know include vitamin C, hesperidin, zinc, garlic, and vitamin D.

Vitamin C: Vitamin C is a nutrient most people are very familiar with. One serving of Florida orange juice is an excellent source of vitamin C, which is a key player in supporting a healthy immune system and may shorten the duration and harshness of cold and flu symptoms.11,12 Make sure to include Florida Orange Juice as a regular part of your healthy diet to help support your immune system overall. Interested in finding new ways to consume vitamin C? See our Homemade Vitamin C Gummies recipe.

Hesperidin: Hesperidin is a plant compound within the family of flavonoids. Flavonoids have been researched for their extensive health properties. For example, a systematic review reported a 33% decrease in upper respiratory tract infections with flavonoid intake.13 Orange juice is a unique source of the flavonoid hesperidin since it is rarely found in other foods.14 Studies have shown hesperidin from orange juice consumption exerted positive effects on the immune system, including altering proteins and lowering the imbalance between free radicals and antioxidants in your body.15

Zinc: One of the not-so-commonly thought of immunity supporters is zinc. Zinc can be found in cells throughout your entire body. Studies have shown zinc to be – helpful for several different aspects of a healthy body including skin care, cognitive functions, improved sensory and overall immune system health. One of zinc’s most vital functions is the production of white blood cells, which are integral in the healing process and can defend your body against a number of infections. As far as the common cold goes, a zinc preparation can be sprayed in the nostrils for helping treat common cold symptoms. Foods high in zinc include beef, lamb, beans and yogurt. Try our Slow Cooker Florida Orange Juice Chili that includes a dose of zinc from beef, vitamin C from Florida Orange Juice, and the added benefits from garlic.

Vitamin D: Did you know that vitamin D also supports a healthy immune system? Vitamin D is needed for bone growth and bone strength, and may help reduce inflammation along with supporting immune system health.17 Vitamin D is produced in the skin by UV rays from sunlight and is only naturally found in a few foods. Most Americans do not get enough vitamin D in their diet.18 Here is some good news though, vitamin D can be found in fortified Florida Orange Juice as well as fatty fish, fortified dairy, and eggs. If you’re looking for a new recipe to help increase your vitamin D intake, check out our Cedar Planked King Salmon Recipe with a Florida Citrus glaze. Use calcium- and vitamin D fortified Florida Orange Juice in this recipe to up your intake of vitamin D.
