At first glance, I really liked this book. The nutritional advice seemed clear, scientifially driven, and made a great deal of sense - it gave me hope and inspired me to look after my health more proactively. However a few alarm bells led me to do some further research on Mr. Holford's advice. And when I dug a little deeper a whole lot of problems arose.
My first problem with this book is that Patrick Holford doesn't have any qualifications that are relevant in the field of nutrition, and a great number of his claims are disputed by others who do. Many offer evidence as to why Holfold's work is not scientifically driven at all. My particular worry is the sheer number of supplements he recommends taking, as well as the high dosages.
For example, he recommends that everyone take 2000mg vitamin C daily, which is 1000% above the RDA. I found plenty of opinions and research on the internet that suggested this level of dose could actually be dangerous at worst, or at best, ineffective. Mr. Holford also recommends that I take 3 supplement packs daily containing a combined 90mg of vitamin B6 (well over 4000% of my RDA), however when I went to order these on the website which sells his own-brand vitamins, the following warning appeared: "10mg of vitamin B6 daily may lead to mild tingling and numbness". Hmmm...
On that basis I bought Ben Goldacre's book "
Bad Science" which to my surprise had an entire chapter devoted to Patrick Holford's dodgy teachings. And from there I found the website http://holfordwatch.info/. Having poured over a number of different sources both pro and against Holford's advice, I would now implore anyone wanting to take on this advice to carefully balance against other research. Don't simply take this book at face value.
My second problem with this book is almost always includes a sales pitch for the author's other products. For example, you can buy a 100% health report for £24.95, and a range of his own branded vitamin supplements from a number of different online stores. He even uses some pressure sales techniques - you can buy a monthly subscription to his 100% Health site for £9.95 per month (min 3 months), but if you don't purchase at the same time as your initial report you will need to pay another £24.95 joining fee.
I actually purchased the 100% Health Report and would strongly advise against it - there is nothing in there that you can't find by reading the book. And the advice is dodgier than ever. However if you do decide to purchase the report, here's a tip: if you don't order the report straight away, after about a week you will start getting promotional codes by email encouraging you to give it a try.
Here's another tip which I picked up from reading Goldacre's book - often PR companies will find ways of getting free publicity to promote their products which are not backed up by scientific research. On that basis I was a bit suspicious about some of the other glowing reviews of this book here on Amazon. And so I clicked on the "See all my reviews" link for each and every other reviewer, and while I found no evidence these other reviews were posted by Holford's people, it was both interesting and informative to see the reviewing patterns of 2 out of the 4 other reviewers.
However I do agree with Hayley that
How Not to Get Fat is a good read.
