Can certain foods boost my immune system and prevent me from contracting COVID-19?

Dietitians of Canada Statement regarding COVID-19

No specific food, supplements, detoxes or cleanses will prevent you from catching COVID-19.
You can however support normal functioning of the immune system with a well-balanced diet following recommendations of Canada’s Food Guide.  Include protein-rich foods, nuts and seeds, fruits, vegetables and whole grains in your diet. 

If you are self-isolating and especially if you have symptoms, it is important to maintain good nutrition and hydration.  Make sure you are eating and drinking regularly, even if you have a low appetite.

At this time, it makes sense to stock up on non-perishable food items so that you do not need to go shopping if you become sick, but avoid panic buying.  Use frozen and canned foods to help reduce the number of visits you need to make to the grocery store.  Having these supplies on hand will ensure you do not need to leave your home at the peak of the outbreak or if you become ill.
