As the coronavirus situation intensifies, you might be wondering: how can I keep myself healthy? And will swallowing a pill protect me from getting sick?
First, there's the not-so-great news. Despite claims you may have seen on the Internet, there's no magic food or pill that is guaranteed to boost your immune system and protect you against coronavirus.
But there's uplifting news, too: There are ways to keep your immune system functioning optimally, which can help to keep you healthy and give you a sense of control in an uncertain time.
Blueberries contain a type of flavonoid called anthocyanin, which has antioxidant properties that can help boost a person’s immune system.
A 2016 study noted that flavonoids play an essential role in the respiratory tract’s immune defense system.
Researchers found that people who ate foods rich in flavonoids were less likely to get an upper respiratory tract infection, or common cold, than those who did not.
