Beta Glucan is considered to be a powerful immune system booster. It is also good for your heart health and regulates blood sugar.
It is naturally in some food, however, no single food will fend off viruses. So be sure to have a balanced diet.

Beans and soy contain zinc— a mineral that helps produce more of your infection-fighting white blood cells. Seafood (especially oysters and crab), as well as lean cuts of beef and pork, also contain zinc. Zinc deficiencies can make you more susceptible to infections.
