The best foods to boost your immune system

Having a strong immune system is crucial to protect the body and keeping it free of infections, diseases and illnesses. Dietary deficiencies can lead to a weakened immune system, making the body vulnerable to various health problems, especially during cold season.

The immune system is not a single entity. To function well, it requires balance and harmony. Researchers are exploring the effects of diet, exercise, age, psychological stress, herbal supplements and other factors on the immune system’s response to them.

Experts from the Harvard Medical School's teach others that following general good-health guidelines is the best step to keep immune systems strong and healthy. Every part of the body functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these:
