It’s hard to believe summer has already begun to wane and that cold and flu seasons are waiting in the wings. Sick people spend piles of money on doctor’s visits and prescriptions medications every year. Others cut illness off at the pass through the use of preemptive measures. A strong immune system is better at coping with an influx of viruses.

A few simple dietary adjustments can improve your chances of successfully fighting off infections during the colder months. White blood cells work as your body’s primary protectors against illness, so any food that can strengthen them will benefit you in the long run. Mushrooms and green tea are just two examples. Foods and drinks rich in vitamin C are similarly beneficial to help boost immune system.
