Your immune system works hard to protect you from injury, illness, and disease. This process usually involves inflammation, a natural response to stress, tissue damage, and harmful stimuli like viruses, bacteria, and toxins. Inflammation functions similarly to an engine warning light, alerting you to the presence of a problem through symptoms such as heat, pain, redness, swelling, and/or loss of function. 85% of the immune system is located in our gut. An anti-inflammatory diet rich in vitamins A, C, and E and the mineral selenium provides your gut with the ingredients it needs to bolster immunity and achieve optimal mental and physical health.
