7 Immune-Boosting Foods You’ll Want To Eat

Citrus Fruits and Berries

First up on our list of immune-boosting foods are citrus fruits and berries which are packed with Vitamin C.  This essential vitamin, which is believed to support the production of white blood cells to help fight illness, is not produced in the body. Vitamin C must, therefore, be acquired from food, which makes citrus fruits and berries an excellent source of Vitamin C:

• Popular citrus fruits include: oranges, grapefruit, tangerines, and lemons.
• Excellent berry choices include strawberries, blackberries, raspberries, and kiwi.

The Recommended Dietary Allowance (RDA) for Vitamin C is 50-60 mg. 1 orange has about 50 mg and 1 cup of strawberries has around 90 mg.

 Red Bell Peppers

Another great immune-boosting food is red bell peppers.  Although not a citrus fruit, red bell peppers are packed with Vitamin C, with 1 cup of red bell peppers actually having twice as much vitamin C as citrus fruits, containing about 120 mg of vitamin C, which is 200 percent of the RDA. 

Red bell peppers are also packed with many antioxidants, some of which have been shown to help fight disease and cancer. Such nutrients make red bell peppers another excellent option among our immunity-boosting foods to add to your plate. 

Broccoli 

Next on our list is broccoli. Known as one of the superfoods, broccoli is low in calories, yet high in nutrients. It is supercharged with Vitamins A, C, and E; all of which work together as antioxidants to help fight off disease. One cup of raw broccoli provides 567 IU of Vitamin A, 81 mg of Vitamin C, and .7 mg of Vitamin E.

Broccoli also provides fiber and potassium, a mineral and electrolyte essential for the functioning of the nervous system. Together, these nutrients make it another excellent option among our immune-boosting foods. 

Spinach

Another superfood among our immune-boosting foods is spinach. Spinach is high in both Vitamin C and folate, which helps the body make new cells and repairs DNA. Like broccoli, spinach is its healthiest when it is cooked as little as possible; however, light cooking activates vitamin A and releases other nutrients.

Recommended daily intake is 2 cups, which can be easily added to your salads, smoothies, and sandwiches.

Garlic

Next on our list of immune-boosting foods is garlic, another superfood used in cooking virtually everywhere across the globe today. Garlic’s immune-boosting properties come from its many sulfur-containing compounds like allicin. It is a low-fat, low sodium way to add flavor to your recipes.

The recommended daily intake for garlic is 1 to 2 cloves per day. However, it’s important to note that in order to get the benefits of garlic you have to eat the real thing; garlic powder does not have the same benefits.

Chicken Soup

Chicken soup is next on our list, and there’s hard science behind this homemade, classic favorite. In addition to protein, which is an essential part of boosting immunity, the ingredients in chicken soup are often high in vitamins K and C. The soup also contains a chemical, carnosine, that helps protect your body from the flu.

Additionally, the warmth and steam from the soup that can help open up your airways and improve airflow when you’re sick, makes it a great option for easing symptoms of such illnesses as the common cold, helping you feel better sooner.

Oysters

Although a bit unconventional, oysters contain essential nutrients with immune-boosting properties, including high levels of vitamin D and C. Oysters are also known for their zinc content, a nutrient with virus-fighting powers, which helps create and activate white blood cells to fight viruses.

Just 1 oyster provides 5.5 mg of zinc which is over half the RDA of 8-11 mg for most adults. Since a little goes a long way, be sure not to eat too many oysters, as this could increase your risk of getting a bacterial infection.

Diet is a cornerstone for great health. Education is therefore important to ensure you have the knowledge to make healthy eating decisions. Now that we’ve covered immune-boosting foods, learn more about healthy eating habits such as essential foods that lower cholesterol or protein-rich recipes for seniors.
