Gluten Intolerance

Up to 6% of the global population suffer from Gluten Intolerance.

If you experience stomach cramps, bloating or other similar symptoms every time you eat food containing gluten, then you may have a gluten intolerance.

But exactly what is gluten? It’s the name of the protein found in cereals and grains, including wheat, barley and rye, that acts like a binder in food and gives it that springy feel. That means if you do have an intolerance you’re likely to feel symptoms every time you eat food that contains cereals or gains, such as bread, pasta, cakes and many commonly eaten foods. This can make shopping and eating out tricky, but thankfully there are plenty of options out there that mean it’s manageable.

What is gluten intolerance?

A gluten intolerance, also known as gluten sensitivity or non-celiac gluten sensitivity, is when your body struggles to digest or metabolise gluten, which results in unpleasant, uncomfortable or painful symptoms.

There is some crossover with celiac disease, which can have similar symptoms to an intolerance. However, the key difference is that celiac disease is caused by the immune system and can have a long-lasting impact on the body.

Gluten Intolerance vs gluten allergy

While it’s often possible for someone to have an intolerance or an allergy to certain types of food, this isn’t the case when it comes to gluten. You most definitely can have a gluten intolerance, but you can’t have an allergy to it. If your symptoms are more in line with an allergy rather than an intolerance, you may have an allergy to another type of food, such as wheat. A wheat allergy or intolerance is commonly mistaken for a gluten intolerance, but there are key differences.

How common is a gluten intolerance?

Gluten is actually a fairly common intolerance, with up to 6% of people around the world thought to have it. This is in addition to those who have celiac disease or wheat intolerance.

Gluten allergy test

Because you can’t have a gluten allergy, there isn’t a test to find out. However, if you experience allergy symptoms after eating certain foods, a blood allergy test can be taken at home and sent to our lab to confirm exactly what foods you have an allergy to in under a week.

How does a gluten intolerance impact your diet?

Because so many different types of food contain gluten – from bread to sauces – it can have a big impact on your diet, including eating out. However, because gluten intolerance is so common, there’s a huge range of alternatives available which means you can continue to enjoy all your favourites.

The important change to make is that you’ll need to pay close attention to product labels to ensure what you buy doesn’t contain gluten. You might be surprised by just how easy making that change can be.
