Heart disease, cancer, diabetes metabolic syndrome, inflammatory bowel disease, obesity - the diseases of western civilisation. What's gone wrong? The Industrial Revolution and our staggering technological and economic development have provided us with unprecedented amounts of food, but is it any good? Renowned nutrition specialist David Farrell is convinced that much of it is not. Evolutionary, we are much the same hominid as our ancestors who first strode the plains of Africa, spear in hand. Our abundant but deficient diet (insufficient roughage, omega-3 fats, too much salt) is inconsistent with our evolutionary heritage.In this common sense and easy-to-ready treatise, David explains where we have gone wrong, and how we can get back on the right track. We have developed marvellously efficient agricultural techniques, such as factory farming of animals and genetically-engineered crops, but do they produce unhealthful, deficient food? Using a few simple dietary changes suggested by David Farrell, we can adapt our modern diet to reclaim the good health benefits enjoyed by our fit forebears.
