Should you go gluten-free?

By Hannah Buckland, Healthy Hearts Care Planner

Going gluten-free has become a common trend; in the UK, 1 in 10 people now avoid gluten and 15% of households prefer not to buy foods containing gluten and wheat. But why? Many people perceive that a gluten-free diet is a healthier way to eat. They make the switch in the hope that it will lead to weight loss, increased energy and a general feeling of improved health. Clever marketing and testimonials in the media reinforce this perception. So, should you go gluten-free? Let’s explore the evidence.


Gluten is a protein found in wheat, barley and rye. A gluten-free diet avoids any foods or drinks made from or containing these grains, including pasta, bread, cereals, and some sauces and ready meals. For those diagnosed with coeliac disease (around 1% of the UK population), a gluten-free diet is vital. Coeliac disease is an autoimmune condition where the body’s immune system attacks its own tissues when gluten is consumed, damaging the lining of the small intestine. Non-coeliac gluten sensitivity can also generate symptoms similar to coeliac disease (bloating, diarrhoea, cramping) and is thought to affect between 6-8% of the UK population. However, for anyone not diagnosed with these conditions, there is no robust or convincing evidence to support gluten avoidance.

In fact, substantially reducing or eliminating gluten-containing foods from your diet could have negative health, social and economic effects. There is some evidence to suggest that gluten-free diets may be higher in sugar and saturated fat, lower in fibre, and may lead to nutritional deficiencies, since gluten-free bread and cereals are not always fortified with the same micronutrients as their counterparts. A gluten-free diet could also have negative social implications; for example, it makes dining with friends or family more complicated and often leads to avoidance of such situations. Finally, the cost of a gluten-free diet can be high, since gluten-free products tend to be more expensive.

On the other hand, there are a lot of benefits to gluten-containing foods. They are relatively easy to cultivate and prepare, they are readily available, and they are cost friendly. So, unless you are a coeliac or have non-coeliac gluten sensitivity, you can enjoy gluten-containing foods as part of a healthy, balanced diet.
