Having studied catering and nutrition at college , I have had an interest in food science for the best part of 40 years. Recently nearing retirement I went to work in a supermarket and was stunned by the amount of junk food and ready meals people bought. I have strongly suspected a link between processed rubbish and obesity but didn’t have the scientific background to prove it. This book was a revelation and I am so glad I read it , packed with facts and information, absolutely fascinating from cover to cover. So glad I read it and would highly recommend it. My son has Colitis so I have just got him to download it.
