I have wanted to write this book for a long time. It started off with a description of the importance of vitamins and minerals, I then added a section on what each vitamin and mineral is, what are good food sources and then what the Recommended Daily Allowance is for the USA and UK. I then decided to expand the book by adding Essential Fatty Acids (EFA) which are critically important for good health. You have to get these from your diet - the body cannot manufacture them. Enzymes are often forgotten or misunderstood, so I added a section on these as well. Enzymes are the "workers" - they make things happen in the body. Without them, you would not digest your food; in addition, they are involved in so many body processes, that without them, your body would cease to function. After this I then included Amino Acids - the building blocks of proteins in the body. There are two types - Essential Amino Acids (which must be provided from the diet) and Non-Essential Amino Acids which the body can manufacture itself. Next, I included a large section on herbal products. Some herbs have been used medicinally for thousands of years - especially in China. I finished this section off with a comprehensive A-Z of herbal products, explaining what they do. And finally, I have included a section on all the body systems - what they are and what their function is, together with a selection of suggested products to help support these systems. I have enjoyed writing this book. In my more than 30 years of doing natural health research, I have never found one book that contained all the information that I needed. It has always been the case that I would have to research many books and articles as well as searching on the Internet. Now I have got everything together in one place, and I will use this book a lot myself - and I hope you will enjoy reading it too and will gain a greater understanding of natural health and the importance of looking after your body.
