Right up until the early 20th century, infectious diseases were always the most important cause of illness and death. Improved sanitation, vaccination and then antibiotics briefly tipped the scales in our favor but in the 21st century, the infectious diseases are making a comeback. Antibiotic and anti-fungal drugs are losing so much of their effectiveness that if current trends continue, many elements of modern medicine, from anticancer drugs to intensive surgeries, will become unusable. And new viruses are entering the human population at an increasing rate.
Fortunately, we have powerful immune systems that have an amazing ability to keep the bugs at bay. Unfortunately, modern lifestyles have harmed those immune systems. They have not only become less able to protect us, they are increasingly turning against us. We see this in the growing epidemics of allergy and autoimmune disease, and our increased vulnerability to infection.This book shows how to undo the damage. It contains a set of simple, science-based steps you can use to rebuild your immune system, strengthen your defenses and live a healthier life.
