An alert immune system is ready to respond to anything that may be a danger to your health. Both under and overreactive states of the immune system can create issues. A deficient immune system may not be as vigilant in the face of a threat. An overreactive system may respond to situations it shouldn’t respond to or create runaway inflammation. The immune dance involves a constant delicate balance of communication and cellular response. Proper nutrition, a healthful microbiome and a balanced inflammatory response all contribute to a properly functioning immune system.
