5 Superfoods to Eat to Combat Flu Season
As the temperatures get cooler, the days get shorter, and we spend more time indoors, it’s also the start of flu season—not to mention any lingering concerns about any COVID-19 surges that would be possible in the region.
Aside from getting your flu shot (and COVID-19 booster!), one of the best things you can do to prevent illness is to boost up your immune system through superfoods.
Ontario Center for Rehabilitation and Nursing has the details in five superfoods that you can work into your diet to allow your immune system to pack an additional punch.
- Green Tea
Work some green tea into your morning or afternoon coffee routine, as the catechins that are in the beverage provide your system with a huge amount of antioxidants that researchers believe can ward off the flu bug.
Berries are a great source of vitamin C, which helps in the production of white blood cells that fight infection. In addition, blueberries are a great source of antioxidants, and raspberries pack a big punch of fiber, contributing to overall health. Berries can be a great healthy snack, or add them to your morning yogurt or oatmeal, or even serve as a naturally sweet dessert to end the day.
Whether is black beans, kidney beans, chickpeas, or green beans, they will all help in the production of white blood cells through a high amount of zinc that’s contained in the legumes. In addition to having beans with soup, chili, and rice, also have hummus as a snack or roast chickpeas in olive oil for a delicious snack.
- Sweet Potatoes
Sweet potatoes help your body produce vitamin A, which increases the number of immune cells in your body and also helps the respiratory system do its job. Just be careful not to use too much butter or brown sugar, which are common in sweet potato dishes.
Salmon is one of the best natural sources of vitamin D, and it’s also packed with heart-healthy omega-3 fatty acids that also benefit the immune system. Studies conducted last year also found that people deficient in vitamin D were twice as likely to contract COVID-19 as those who have the proper amount in their system.
