Overall, your immune system does an excellent job of defending you against harmful substances, germs and cell changes that could make you ill. However, being mind­ful of the food and bev­er­ages you con­sume can also help sup­port your immune sys­tem and keep you well.

Kelly Springer, a registered dietician and owner of Kelly’s Choice Nutritional Company says the immune system is very complex and a huge proportion of your immune system is actually in your gastrointestinal tract. The human digestive system has over 100 trillion bacterial cells swimming around and the gut microbiome plays a very important role in benefiting your immune system.
