This book explains with the use of more than 1000 scientific references why most people should be taking supplements. It shows that not only are they extremely safe but eating a balanced diet all of the time and absorbing the required nutrients all of the time are almost unobtainable for people. It shows that it is no longer possible to get all the nutrients that should be in our food. Through modern cropping, growing and harvesting techniques, transport, storage and marketing, not to mention processing and cooking, it is possible to lose 100% of the nutrient value of the food and, in its place, add toxins. Meanwhile, most people rarely consume their full share of nutritious foods. Then add to this the many new stressors, including environmental toxins and modern day stress that increase the body's need for nutrients. The science is overwhelming on the benefits of supplementing, not only for the general population but also for specific illnesses and disease conditions such as heart attack, stroke, cancer, diabetes, asthma, Alzheimer's and many more which are covered in this book.
