Gluten is most often associated with wheat and wheat-containing foods that are abundant in our food supply. Negative media attention on wheat and gluten has caused some people to doubt its place in a healthful diet. There is little published research to support these claims; in fact published research suggests the opposite.

The gluten-free food industry has grown 136% from 2013 to 2015 with almost $12 billion in sales in 2015. Interestingly, studies show that people who do not have celiac disease are the biggest purchasers of gluten-free products. [11] Consumer surveys show that the top three reasons people select gluten-free foods are for “no reason,” because they are a “healthier option,” and for “digestive health.” [12] For those who are not gluten-intolerant, there is no data to show a specific benefit in following a gluten-free diet, particularly if processed gluten-free products become the mainstay of the diet. In fact, research following patients with celiac disease who change to a gluten-free diet shows an increased risk of obesity and metabolic syndrome. This could be partly due to improved intestinal absorption, but speculation has also focused on the low nutritional quality of processed gluten-free foods that may contain refined sugars and saturated fats and have a higher glycemic index.
