Why are we waging a war on wheat? - Health

There is a growing movement afoot to demonize one of the staples of the Canadian harvest: wheat.



An increasing number of books, blogs and celebrities have fingered wheat as the cause of a variety of conditions, from obesity to heart disease, as well as a host of digestive problems.


One of the most talked-about health books right now is Wheat Belly: 


Lose the Wheat, Lose the Weight and Find Your Path Back to Health, a New York Times bestseller by U.S. cardiologist Dr. William Davis.


'I think people are willing to do anything to alleviate their digestive concerns and try anything to resolve their weight issues.'— Susan Watson, registered dietitian


"I think people are willing to do anything to alleviate their digestive concerns and try anything to resolve their weight issues," says Susan Watson, a registered dietitian in Winnipeg, about the growing anti-wheat movement.


"From a general health standpoint, unless you're celiac or have a diagnosed wheat intolerance, cutting any food group or any food product completely out of your diet is not generally recommended,"
says Watson.



The antipathy to wheat is partly attributable to a growing awareness of celiac disease, an autoimmune condition that affects approximately one in every 133 people in Canada. 


Celiac disease occurs when the small intestine is unable to properly digest gluten, a protein that appears in wheat as well as other grains such as barley, rye and spelt.


For celiacs, eating gluten-rich foods can make it difficult for the body to absorb nutrients, which can lead to everything from anemia to osteoporosis.



There is also another subset of people who suffer "non-celiac gluten sensitivity," which can include an allergy to wheat.



Although celiacs and the wheat allergic may experience similar symptoms, such as cramps and diarrhea, "a wheat allergy does not damage the intestine, whereas celiac disease does," explains Novella Lui, a Toronto-based dietitian.



In any event, doctors and naturopaths generally counsel celiacs and those with non-celiac gluten sensitivity to go gluten-free.


But the current anti-wheat trend isn't simply a response to celiac disease. In fact, it is increasingly being pitched as a healthy choice for everyone, which is what Davis argues in Wheat Belly.


Davis says he discovered the harmful effects of wheat several years ago, "when I made myself diabetic by accident."

Despite being on a low-fat, vegetarian diet and jogging up to eight kilometres a day, Davis found that his blood sugar was inexplicably spiking.


It didn't become clear to him what was going on until he began doing research into how to prevent heart disease. Then he learned that it was impossible to control the risks of heart disease – such as coronary atherosclerosis – if the patient was diabetic or pre-diabetic.


And one of the things that raises blood sugar is wheat, which is the basis of everything from bread to pasta to pastries.

"The glycemic index of wheat is very high, and wheat products dominate the diets of most Canadians and Americans," Davis said during a phone interview from his office in Milwaukee, Wis.



Not only does wheat raise blood sugar, but Davis says that in the digestion process, one of the proteins contained in wheat — gliadin — becomes "degraded to a morphine-like compound" that creates an appetite for even more wheat.


A little harsh?


Davis contends that significant wheat consumption leads to the development of "deep visceral fat" in the stomach area, and that cutting it out of a person's diet can yield significant weight loss.



But Susan Watson, who runs the nutrition counseling firm A Little Nutrition, says that while the general message of Davis's book is good, the prescription is a little harsh.


"If you avoided white bread and white rice, and switched it with whole-grain bread and whole-grain rice, you're getting a way better health benefit than cutting out [all] wheat."



Watson says that any celebrity touting a particular diet might well be getting some sort of financial kickback.
 


Furthermore, she says it's confusing to consumers.

"So what if so-and-so has found all these health benefits – their health concerns are not necessarily the same as the individual that's reading it or seeing it on TV," Watson says.
Market share

Even so, it's clear that gluten-free products are commanding an ever-increasing market share.


A July 2011 report by Agriculture and Agri-Food Canada said that the gluten-free market in the U.S. reached about $1.3 billion US in sales in 2011, and was expected to achieve a growth rate of 31 per cent from 2011 to 2014.



Newell says that if you add celiacs and those with a gluten sensitivity, you're looking at six per cent of the population.

"Six per cent of the population is a non-trivial amount, and these people are not going to go back to eating wheat," she says.


Furthermore, she says that among general consumers, the term gluten-free has come to have positive connotations.


"It's perceived as better-quality food, and it's perceived as healthier and better for your family," Newell says, likening it to kosher food, which enjoys a similarly positive brand identification.


Nutritionists agree, however, that gluten-free eating is not inherently healthier. 


Many of the ingredients that are substituted for wheat – such as rice flour or potato starch – are just as rich in carbohydrates.


Davis, too, is wary of people quitting wheat only to embrace gluten-free foods, "which send your blood sugar and insulin sky-high, even more so than wheat."
