NUTRITION & SCIENCE
WHAT'S THE EVIDENCE?
This book is designed to give a completely up-to-date summary of Nutritional Medicine as it applies to front line medical professionals, medical students and the interested layperson. Newspapers often give contradictory and confusing reports on issues such as alcohol intake, dietary sugars versus fats and the value or not of taking supplements. In addition, many GPs are as confused as their patients on these matters as they get very little education in nutrition either at medical school or afterwards. But nutritional medicine is not really that confusing. There is some disagreement among experts but there is a consensus on the most important issues, albeit with slight variations.
I have summarised these generally agreed opinions but explained where there are differences of opinion and the reasons for these. This book is written in a style I use to communicate with patients and GP colleagues, using minimal scientific jargon.
I am a Fellow of The Royal College of General Practitioners and have been a GP for 42 years. Most of my research is in this area and includes research on trace elements in the diet, dietary advice and the heart, diverticular disease and the role of probiotics in primary care.
There are two medical opinions on Nutritional Medicine and the use of nutrition supplements that go back to my student days that are both wrong:
1) You don't need to take vitamin and mineral tablets if you eat a well balanced diet.
2) You can take vitamin and mineral tablets if you really want to. They may not do you any good but they can't do you any harm.
The truth of the matter is rather complicated. For instance, taking folic acid vitamin tablets is officially recommended when trying to get pregnant. To find out why both statements are wrong, you might have to buy my book!
