This series was absolutely eye-opening and amazing! This series takes a scientific approach (the best type) to the entire world of nutrition. It is very easy to follow and understand. Prof. Andling is compelling and her attitude is very open and realistic. I have recently become a strict vegetarian on an entirely plant-based vegan diet (no eggs, cheese, milk, animal products). This series even helped me to better understand how our body works, how food is digested, why getting your vitamins and minerals from whole foods is better than supplements, as well as how to create complete proteins, very essential for a plant-based diet. My Husband is a meat eater and I learned why it is so important to use meat as a side dish in a sea of whole foods and have implemented that in his diet as well. This book also discusses many diseases and other dietary issues that you may experience including real life examples and it will definitely make you assess what types of meds, vitamins, supplements, etc. that you are currently on. It also discussing "dieting" and how our body responds. Towards the end there is an assessment to help you reach your goals or better understand your future nutrition. I am listening to it again! I am also ordering the DVD to send to my inlaws and will keep it handy for the future as each section may apply to your life in different stages or for different people you support. The only downside is she talks about a reference book throughout that we would normally have a copy of, I tried to find that book on Amazon with no luck thus far. I would love to have this entire series in a textbook form. I must say, science has changed so much in the last 10-20 years and I am sure that many things we believe are healthful may indeed drastically change in the future thanks to the progression of science and studies. So I look forward to the updated version one day! P.S. thanks to this course I have a newfound interest in doing more research, as nutrition and fitness which she does talk in great detail about as well, is really our only insurance! Health = Wealth!!!!!
