It's that time of the year again when flu and colds are rampant. While flu vaccines and regular hand-washing are some of the preventive measures we can take, another way to boost our immune system is to eat healthily. Many foods are excellent sources of nutrients that can help us ward off illnesses. So if you want to give your immune system a boost, here are some food options you should include in your diet:
Citrus Fruits: Oranges, Lemons, and Grapefruits
Citrus fruits are a staple during the flu season, and for a good reason. These fruits are rich in vitamin C that boosts the production of white blood cells, a critical component of the immune system. Additionally, vitamin C is an antioxidant and protects the body from harmful free radicals that can cause damage at a cellular level.
Dark Leafy Greens: Spinach, Kale, and Broccoli
Green leafy vegetables such as spinach, kale, and broccoli are high in antioxidants like vitamin C, as well as, vitamins E and A. These vitamins help in the production of white blood cells and protect the body from oxidative stress. Additionally, kale is also an excellent source of calcium that is essential for building strong bones and teeth.
Ginger
Ginger plays a crucial role in reducing inflammation and is a remedy for nausea. It's also an excellent immune-boosting ingredient that can help prevent viral infections. In traditional medicine, ginger is used for its antiviral properties and is believed to help prevent the onset of colds and flu.
Yogurt
Yogurt is rich in probiotics, which are the good bacteria that help keep your gut healthy. About 70% of our immune system lies in our gut, making a healthy gut integral to optimizing immune function. Probiotics in yogurt boost good bacteria, which can help reduce inflammation, and reduce the risk of bacterial and viral infections.
Almonds
Almonds are a great source of vitamin E, an essential antioxidant for enhancing the immune system. It is believed to improve immune function by stimulating the production of natural killer cells that fight off infections. Additionally, eating almonds also delivers a healthy dose of zinc, an essential mineral that the body needs to fight off infection and disease.
Garlic
Garlic is a popular herb used in cooking for its delicious, pungent flavor. Not many know, however, that it's also an immune-boosting superfood. Garlic contains sulfur compounds that enhance the activity of white blood cells and boost the immune system's response to infections. It's especially helpful in fighting off respiratory infections like colds and flu.
Including these foods in your diet is an excellent way to boost your immune system's natural defenses and keep you healthy during the flu season. Incorporating these foods in your meals doesn't have to be challenging. You can get creative with your recipes and look for ways to incorporate them into your diet to ensure you get all the nutritional benefits. Remember, a strong immune system is your body's first line of defense against any infection or disease.
