I have found this book to be one of the most helpful in getting better health. I have coeliac disease for 50 years before being diagnosed and fybromialgia for the last 25 years this book has helped me feel a lot better i have now been having green smoothies for the last 8 weeks i have more energy and feel less reactions to food as im very sensitive even to some glutenfree food but gradually im improving. it has lead me to reading the CHINA STUDY and dr doug grahams 80/10/10 all three have given me a better outlook on food and diet and feel a noticable difference when eating the diets these books recommend. I just wish i had found this out when i was much younger im now 61 years so that i could have had a much easier course through life i can only recommend these books and particularly green smoothies.
