Throughout human evolution, you couldn’t help but have a properly calibrated immune system. It got trained by a diverse gut flora in infancy, and then challenged with frequent exposures. These days, there are so many aspects of modern life, from antibiotics, to excessive hygiene, to pesticides that cause leaky gut, that leave our race car immune systems very confused, speeding in all the wrong directions. A dysregulated immune system might attack the self (autoimmune disease), and fail to keep an infection in check. I think we should do what we can to maintain strong terrain and a balanced, calibrated immune system. How? Longer conversation, but it starts with eating fermented foods, avoiding interventions that damage our guts, gardening, and managing stress.
