Staying healthy, especially in winter months, means doing everything you can to keep your immune system functioning optimally. What you eat can significantly impact how your immune system operates. And while your immune system doesn’t necessarily keep your mouth healthier, nutrient-rich foods can ensure both your overall and dental health don’t suffer.

So how do you ensure you’re getting all the nutrients you need? There are always mineral supplements and multivitamins to help fill in the gaps, but the best way to make sure your immune system has a fighting chance is to incorporate the right foods into your daily diet.

From specific fruits and vegetables to nuts, fatty fishes, seeds, teas and more, your body’s immune system will thank you for all the goodies it’s going to get. These foods have everything you need.

Many foods contain nutrients that can help your body fight off viruses, including the following.

Foods to eat when sick with flu or cold

20 foods that are good—and good for your immune system

Life can be pretty miserable when you’re constantly coughing, sneezing, fighting a fever, or trying to soothe a sore throat. There’s a good reason that generations have turned to hot drinks and soups to ease discomfort. The steam and heat from hot fluids can have a decongestant effect that loosens mucus. So, break out the broth, chicken soup and hot teas.

In addition to the tried and true foods, don’t forget foods and drinks containing ginger. Ginger has potent medicinal properties. Ginger can help soothe sore throats and reduce inflammation and congestion. Ginger can even soothe an aching tummy or calm nausea. 

And ginger has all the great “anti” qualities that are a must for treating colds and touches of flu, including antibacterial, antiviral, antioxidant and anti-inflammatory.
