Medical matters have consumed much of our attention over the past months and brought us all to a new level of both concern and care for our health. There has been one very positive message, We can, to a large extent, control our level of risk when confronted by a seemingly relentless health threat such as Covid-19. Pre-existing conditions such as diabetes and obesity have been cited by health officials worldwide in contributing to serious illness and death in Covid patients. The healthier people were when the SARS-CoV-2 coronavirus threatened, the more likely they were to have mild symptoms and survive the disease, or in fact to avoid getting sick altogether. That is one reason why we are expanding the scope of this text beyond musculoskeletal conditions and their associated inflammation to include inflammation in general, and how we can manage it. Proper nutrition emerges as the answer to many of our ills, and with this edition we examine and recommend how to treat ourselves by understanding inflammation and its causes. Along the way we draw on the emerging science of the microbiome, especially the beneficial collection of bacteria, fungi and other microorganisms that inhabit our gut, helping us both process food and fight disease. Naprapathy treats inflammation at the musculoskeletal level. Nutrition is often the anti-inflammatory answer that our other systems need. Please join us on this enhanced journey to good health.
