If you are experiencing any of the situations, then you might want to try these six types of food to help boost your immune system.

The Immune System

The immune system is the body’s defense mechanism that provides a robust anatomical barrier.  The gastrointestinal tract is one of the barriers. It has many defense mechanisms such as peristalsis, gastric acid, bile acids, digestive enzymes, flushing, thiocyanate, defensins, and gut flora in the body. The gut flora is the critical focus for many health professionals; however, all the essential defense mechanisms rely heavily on the gastrointestinal tract to function efficiently.

There are ways to benefit the immune system as one of the ways is to plan meals that are filled with necessary nutrients that can fight off infections. Prebiotic and probiotic-rich foods help enhance microbial diversity in the gut, while vitamin C-rich foods can mop up the free radicals that have entered the body. Another benefit is to avoid foods that promote infections like heavily processed foods, added sugars, and sodas. When it is not consumed in the body, it can help boost immunity and enrich the gut microbiome. Here are the six foods to help boost the immune system in the body.
