In the last two years, Americans have become more interested in “functional foods” to boost their immune systems. Unfortunately, there is no one magic food that will make you invincible to colds, flu, and COVID. Over the long run, though, two eating habits can cut your risk of catching contagious illnesses.
Limit foods high in sugar, salt, and/or saturated fat. Too much of these can keep your white blood cells from
working as well as they should. Drink water, unsweetened tea, or milk more often instead of pop. Snack on fruits or
vegetables; choose baked chips over regular; enjoy whole grain granola bars over cookies. Eat baked or grilled meats
instead of fried.
Aim for at least 4–5 cups of fruits and vegetables a day. Fruits and vegetables are the main source of the vitamins
and minerals you need to resist illnesses. For example, the tomatoes and kale in this month’s soup recipe give you lots
of the antioxidant vitamins A and C. The lentils are rich in zinc, which is also important to immune health.
