Immune health is impacted by stress, lack of sleep, chronic viral or bacterial infections, nutrient deficiencies, and consumption of processed foods. Roughly 70% of the immune system is located in the gut, which makes the connection between diet and immune health vitally important.
The diverse populations of bacteria in the G.I. tract interact with immune cells to mount proper immune responses to threats (bacteria, viruses, stress). Thus, adequate amounts of phytonutrients, fibers, antioxidants, vitamins, and minerals are essential to sustain populations of beneficial bacteria and support a healthy immune system.
