What used to be prescription-only food is now a global health fad. But for how much longer? New research from Harvard University has found a link between gluten-free diets and an increased risk of developing type 2 diabetes.
Gluten is a protein found in cereals such as wheat, rye and barley. It is particularly useful in food production. For example, it gives elasticity to dough, helping it to rise and keep its shape, and providing a chewy texture. Many types of foods may contain gluten, including less obvious ones such as salad dressing, soup and beer.

Coeliac disease is an autoimmune disorder in which the body mistakenly reacts to gluten as if it were a threat to the body. The condition is quite common, affecting one in 100 people, but only a quarter of those who have the disease have been diagnosed.
There is evidence that the popularity of gluten-free diets has surged, even though the incidence of coeliac disease has remained stable. This is potentially due to increasing numbers of people with non-coeliac gluten sensitivity. In the Continue reading
