10 Top Superfoods to Support the Immune System During Flu Season

Last Updated on May 16, 2024 by Marjorie R. Rogers

As the flu season approaches, it’s crucial to bolster your immune system. An effective way to do this is through your diet. This article will guide you through ten superfoods to support the immune system, helping you to maintain your health during peak flu periods.

Understanding the Immune System

Your immune system is a complex network of cells, organs, and tissues that work in unison to defend you against pathogens, including viruses, bacteria, and foreign bodies. When your immune system is strong, you have a better chance of fighting off illnesses. Proper nutrition is vital for keeping this system running efficiently.

The Top 10 Superfoods

Citrus Fruits

  1. Citrus fruits like oranges, lemons, limes, and grapefruits are high in vitamin C, a vitamin essential for the growth and repair of all bodily tissues. It helps in the production of collagen, absorption of iron, and the maintenance of cartilage, bones, and teeth. More importantly, during the flu season, vitamin C helps to boost your immune system by increasing the production of white blood cells, which are key to fighting infections.

Garlic

  1. This potent ingredient does more than flavor your food; it’s also recognized for its health benefits, including its immune-boosting properties. Garlic has been used in medicine for centuries. It contains allicin, a compound that may help lower cholesterol and reduce blood pressure. Additionally, garlic has significant antimicrobial and antiviral properties that help ward off illness.

Ginger

  1. Another ingredient famous for its medicinal properties, ginger can help decrease inflammation, which is helpful in reducing a sore throat and other inflammatory illnesses. Ginger also helps with nausea and chronic pain while possessing cholesterol-lowering properties.

Spinach

  1. Spinach is not only rich in vitamin C but also packed with numerous antioxidants and beta-carotene, which may increase the infection-fighting ability of our immune systems. It’s healthiest when cooked as little as possible to retain its nutrients. Light cooking enhances its vitamin A and allows other nutrients to be released from oxalic acid.

Yogurt

  1. Yoghourt can be a great source of vitamin D, which helps regulate the immune system and is thought to boost our body’s natural defenses against diseases. Look for yoghourts that have “live and active cultures” printed on the label, like Greek yoghourt. These cultures may stimulate your immune system to help fight diseases.

Almonds

  1. Nuts, such as almonds, are not only packed with vitamin E, which is key to a healthy immune system, but they also contain manganese, magnesium, and fibre. A half-cup serving, which is about 46 whole, shelled almonds, provides nearly 100 percent of the recommended daily amount of vitamin E.

Turmeric

  1. Turmeric is a key ingredient in many curries. This bright yellow, bitter spice has also been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. Research suggests that high concentrations of curcumin, which gives turmeric its distinctive color, can help decrease exercise-induced muscle damage.

Green Tea

  1. Green tea is packed with flavonoids, a type of antioxidant. It also has high levels of epigallocatechin gallate (EGCG), another powerful antioxidant. EGCG has been shown to enhance immune function. The fermentation process black tea goes through destroys a lot of the EGCG. Green tea, on the other hand, is steamed and not fermented, so the EGCG is preserved.

Papaya

  1. Papaya is another fruit loaded with vitamin C. You can find 224% of the daily recommended amount of vitamin C in a single papaya. It has a digestive enzyme called papain that has anti-inflammatory effects, and papaya has decent amounts of potassium, B vitamins, and folate, all of which are beneficial to your overall health.

Poultry

  1. When you’re sick, chicken soup is more than just a feel-good food with a placebo effect. It helps improve symptoms of a cold and also helps protect you from getting sick in the first place. Poultry, such as chicken and turkey, is high in vitamin B-6. About 3 ounces of light turkey or chicken meat contains nearly one-third of your daily recommended amount of B-6, which is important for the formation of new and healthy red blood cells. Stock or broth made by boiling chicken bones contains gelatin, chondroitin, and other nutrients helpful for gut healing and immunity.

How to Incorporate These Superfoods into Your Diet

Incorporating these superfoods into your daily diet can be simple and delicious. Start your morning with a citrus fruit smoothie, use ginger and garlic when cooking meals, or replace your afternoon coffee with a cup of green tea. For snacks, opt for a handful of almonds or enjoy slices of papaya.
