Gluten-free diet had been recommended for people who had celiac disease. Celiac disease refers to condition where ingesting gluten can result to damaged small intestines. As a result, gluten-free diet became popular even to non-celiac disease sufferers.

There are several disadvantages in sticking to a gluten-free diet when one does not suffer from gluten-intolerance. Non-gluten diet is quite expensive. This might add to the expense of people who live on a tight budget. In fact, students who choose to go for non-gluten diet were advised to find cheaper substitutes. Avoiding products such as gluten free pasta or noodles would really help stretch a student's budget, according to University Herald. It would be cheaper to shift from non-gluten foods to gluten free products. It would be cheaper and healthier to eat foods with gluten as well.

In fact, a recent study by researchers in Harvard University revealed that a gluten-free diet had negative effects. Based on a study conducted in the last 30 years, people who stayed away from foods with gluten faced increased risk of type 2 diabetes. The findings were based on data from 200,000 participants, according to ABC News.

The research, however, focused on comparing effects of low and high consumption of gluten and not the effects of gluten-free diet.

This means that although a positive association between lack of gluten and Type 2 diabetes was established, the reason was never explained. There were some researchers who believed that it was the high fiber content of foods with gluten that reduces the risk of having Type 2 diabetes, not just the consumption of a gluten-rich diet, according to Popular Science.

It will be best for people with celiac disease to add foods free of gluten but rich in fiber to their diet. Eating apples, almonds, chocolates, broccoli, garbanzo beans and buckwheat will provide them with fiber they missed because of the restrictions on their diet. Daily gluten-free diets might result to some health issues.
