10 Immune Boosting Foods to Keep You Healthy

As Coronavirus (COVID-19) continues to impact our communities and the larger world around us, staying healthy is on the forefront of everyone’s minds. Simple hygiene practices such as washing hands and administering to social distance rules can go a long way, but the food we choose to eat may also have a strong effect on our continued health.

In a recent interview for The New York Times, Dr. Dariush Mozaffarian, dean of the Freidman School of Nutrition Science and Policy at Tufts University, cites a national report describing poor diet as “now the leading cause of poor health in the U.S.” and the cause of more than half a million deaths per year. The problem is only exacerbated now, with “poor diet contributing to high blood pressure, high cholesterol, diabetes or pre-diabetes, which pose the biggest risk, beyond age, for illness and death from Covid-19.”

Incorporate the following foods into your quarantine diet, packed with antioxidants and vitamins, to boost your immune system.
