Citrus Fruits: Powerhouses of Vitamin C

Citrus fruits like oranges, grapefruits, and lemons are great for boosting the immune system. They are full of vitamin C. This nutrient is key for supporting the body’s natural defenses.

Oranges, Grapefruits, and Lemons

Vitamin C helps make white blood cells, which fight infections⁵. Citrus fruits like oranges give you a lot of vitamin C. For example, one orange has about 75 mg⁵. Grapefruits have around 39 mg per half⁵.

Whether you like the sweet taste of oranges, the slight bitterness of grapefruits, or the zesty lemon flavor, adding these citrus powerhouses to your diet can really help your immune system⁶.

Immune-Boosting Foods with Antioxidant Properties

Foods full of antioxidants are key for a strong immune system. They fight off harmful free radicals that can harm cells and weaken our defenses. Some veggies and fruits are loaded with vitamins and antioxidants that boost the immune⁷.

Red bell peppers have almost 3 times the vitamin C of oranges, which is great for the immune system⁷. Broccoli is full of vitamins A, C, and E, plus fiber and antioxidants that help fight infections⁷. Spinach is packed with vitamin C, antioxidants, and beta-carotene, boosting immune defenses⁷.

Oily Fish: Rich in Omega-3 Fatty Acids

Oily fish like salmon, tuna, and mackerel are packed with omega-3 fatty acids. These fats are great for fighting inflammation and boosting the immune system⁹.

Eating oily fish often can bring many health perks. It may lower the risk of rheumatoid arthritis, a chronic condition⁹. Omega-3s might also cut down the risk of breast and colorectal cancer⁹.

Omega-3s do more than fight inflammation and support immunity. They might help prevent age-related eye problems and diseases⁹. Some studies also link them to a lower risk of Alzheimer’s disease and dementia⁹.

To get enough omega-3 fatty acids, aim for one to two seafood servings a week, as advised by the Dietary Guidelines for Americans⁹. If you have heart disease, your doctor might suggest about 1 gram of EPA and DHA daily⁹.

Omega-3 Sources and Considerations

Oily fish are top sources of omega-3 fatty acids. But, turning alpha-linolenic acid (ALA) into EPA and DHA in the body is hard, less than 15% efficient¹⁰. So, eating whole foods is better than just taking supplements.

For example, mackerel gives you 0.59 grams of DHA and 0.43 grams of EPA per serving¹⁰. Wild salmon has 1.22 grams of DHA and 0.35 grams of EPA¹⁰. Canned sardines offer 0.74 grams of DHA and 0.45 grams of EPA per serving¹⁰.

The FDA says don’t take more than 5 grams a day of EPA and DHA from supplements, as it could affect some medicines, like blood thinners⁹. Pregnant or breastfeeding women and kids should eat 8 to 12 ounces of fish and seafood weekly for the best health of their babies⁹.

“Incorporating oily fish into your diet is a simple and delicious way to boost your omega-3 intake and support overall health.”

“Cruciferous vegetables are packed with an array of essential nutrients and potent antioxidants that can support a healthy immune system and reduce the risk of chronic diseases.”

In 2018, another study found that garlic extract supplements improved immune cell function and reduced cold and flu symptoms¹⁷. Adding garlic and ginger to your meals might give your immune system a natural boost.
