Gluten-free diets are becoming more and more popular. One percent of the USA population is diagnosed with intolerance to gluten, but there are 1.6 million who are on a gluten-free diet in the belief that it is healthier for them.
The truth is that if you do not have the Celiac disease, consuming or excluding gluten from your diet makes no difference. The element itself acts like a glue in the composition of bread or pasta, helping the products to keep their shape. That is why when you order a gluten-free pizza it does not look as appetizing as the ordinary one. Intolerance to gluten can cause the patients to feel bloated and nauseous, it even leads to headaches and diarrhea. People at Bulletproof Coffee (wikipedia.com) understand that the food factories are taking advantage of the increasing interest towards gluten-free diets and release a wide number of products, pricing them accordingly.
The good side of this is that the people who really have the intolerance can vary their menu. The bad side is that a lot of others keep a diet that leads to no benefit for their health but simply preoccupy themselves with the avoidance of gluten for the sake of it.
