This screams low carbohydrate fad to me
In fact he states that maintaining a low carbohydrate diet is healthiest
Having a quick flick through his references, they are all individual studies and a lot of them done in coeliac patients who have diagnosed therefore have diagnosed gluten intolerance. For the general population gluten isn't harmful or dangerous. You can't extrapolate results done in a group of patients with a known gluten allergy to the general population. Not to mention a lot of his studies are old, some dating back to the 1960's.
Some of the claims made are that when people remove wheat from their diet, they lose weight and their 'wheat belly'. Well duh... removing an entire food component from your diet is bound to make you lose weight. I bet in the standard american population when people remove wheat from their diet they don't replace it with other healthy carbohydrate foods, e.g. legumes, beans, pulses, rice, fruit. They simply remove wheat from their diet (cereals, bread, pasta etc), all foods which provide energy and carbohydrate, yes. So the subjects are therefore eating a standard low carbohydrate diet and restricting their energy intake, of course they will lose weight. But it's not sustainable nor healthy.
The problem I see with this book is it blanketly says wheat is bad, will make you fat and give you diabetes, which again sounds like low carbohydrate preaching. Yes a diet high in refined, processed and low fibre wheat products like white bread, bagels, hot-dog bus, pastry etc have been shown increase the of risk heart disease and overweight. There is some very good evidence for this. But these products are generally high in sugar and fat as well, so which is the culprit? Regardless highly refined carbohydrate products are not good for your health, yes.
There is no good evidence that wholegrain wheat products cause heart disease, diabetes and obesity. In fact there is a lot of evidence to show quite the opposite. Wheat products which are high in wholegrains and fibre can help to reduce cholesterol and protect against cancer particularly colon cancer. Because they are low GI they don't cause a large glycemic response in the body and therefore are suitable choices for people with diabetes.
However after moving here from Australia, I have seen these aforementioned options are pretty scarce in the US supermarket. There are a lot (mostly) refined wheat products on the shelves. Not to mention the US portion sizes, whoah! I think if anything the portion sizes eaten of these foods is more pertinent. I was in France recently and they eat white baguettes for breakfast, lunch and dinner... yet you hardly ever see any overweight people. They also eat very small meals by american standards and are more active...
With overweight and obesity it has to be a multifactorial problem... a diet too high in sugar, fat, processed carbs and alcohol. Combine that with very little exercise and drive through ATM's and BAM... obesity. I don't think you can make the claim that wheat is the one main causative factor.
Lastly I wouldn't trust a guy (cardiologist or not) who is saying to avoid a wholegrain wheat cereal but advocates the use of artificial sweeteners, mayonnaise, sour cream and parmesan cheese in his recipes in the back. Yes i'm sure it's the All-bran that will make you fat, not the sour cream! I wonder what his stance on meat is?
Having said all that I haven't read the whole book, just flicked through what is visible on Amazon. So open to objection...
