Gluten is found in wheat, rye and barley and gives food a chewy texture and elasticity during the baking process. The popularity of the diet is thought to have been encouraged by celebrities such as Victoria Beckham, Gwyneth Paltrow and Miley Cyrus, who have promoted their ‘wheat-free’ lifestyles. The researchers said increasing numbers of people believe gluten may increase the risk of obesity, cardiovascular disease, psychiatric problems and metabolic issues. In fact, less gluten in the food will produce heart problems. “The promotion of gluten-free diets among people without coeliac disease should not be encourage, “ is what they say. Separate research, also by experts at Harvard, concluded in March that people with a low-gluten intake were also at greater risk of developing type two diabetes.
