One of the best ways to keep the immune system strong is to eat a diet rich in a variety of fruits, vegetables and whole grains – all of which contain phytonutrients that boost immunity and help fight off flu and other viruses, she said. Green and white tea, shiitake mushrooms, unsweetened yogurt and fermented foods containing probiotics are also great foods to boost immunity, as are garlic and ginger.
You can also help your body ward off viruses by staying hydrated, staying rested, washing your hands diligently and by exercising 30-60 minutes a day.
Green also recommends asking your doctor to check your vitamin D levels. This nutrient is essential to maintaining a healthy immune system and is commonly deficient.
