What we eat now will determine the disease patterns in our future. Most of the chronic illnesses from which we suffer today were either rare or unheard of just 100 years ago - and still don't exist in many countries where traditional diets are widely followed. The scientific literature about this is abundant and clear. This information shows how changes in lifestyle and diet can not only reduce the chance of these chronic diseases but also, in many cases, reverse these conditions without the use of prescription drugs.
