What does a gluten-free diet do and are there any side effects? How can you switch to a gluten-free diet? Find out more about gluten-free nutrition and gluten-free foods.
A gluten-free diet cuts out all foods that contain gluten. Gluten is a protein found in certain grains such as wheat, rye and barley. It makes certain types of flour suitable for baking and is mainly to be found in products made from grains.
However, gluten can also be contained in products that, at first glance, have nothing to do with grains. Gluten is a good emulsifier and carrier of flavourings. It gels, binds water and stabilises. As a result, the food industry often uses it as an auxiliary ingredient in ready-made products and highly processed foods.
What are the advantages of a gluten-free diet? Following a strict life-long gluten-free diet is the only treatment option available to people with coeliac disease. Even small traces of gluten can damage the mucous membrane of the small intestine again. Specific benefits of a gluten-free diet for those affected are:
Living gluten-free has no benefits for people who are not affected by coeliac disease or gluten sensitivity. Healthy people sometimes report an increased sense of well-being due to a gluten-free diet. However, researchers point to a placebo effect whereby those who believe they’re eating a healthy diet feel healthier too.
Does a gluten-free diet have side effects? A gluten-free or low-gluten diet does not automatically pose a health risk. However, avoiding gluten without consuming an equivalent substitute can lead to nutrient deficiencies. This is because gluten-containing foods such as whole wheat are important sources of fibre, vitamins and minerals. In addition, a gluten-free diet can also cause constipation. That said, this can be prevented with a sufficient intake of fibre and fluids.
If you are unsure about the risks of a gluten-free diet, talk to your doctor or health care professional before making any dietary changes. They will tell you whether this type of diet is suitable for you and, if necessary, arrange for testing. A change in diet should always be overseen by a nutritionist to avoid any mistakes.
Note: some people want to lose weight using a gluten-free diet, but this diet does not automatically lead to weight loss. What matters is a balanced diet combined with enough exercise.
If you have to switch to gluten-free food, you should check each foodstuff systematically. Foods containing gluten include:
If you are on a gluten-free diet, you should always check the ingredient list when buying processed products. Gluten is often used in the food industry as an auxiliary ingredient (e.g. as an emulsifier, carrier or binder).
When switching to gluten-free foods, there are several alternatives available to you. You can use the following list as a guide when buying gluten-free foods:
Unprocessed foods such as meat, fish, eggs, milk and dairy products, vegetables, fruit, vegetable oils and sugar are also gluten-free. Gluten is an allergen and therefore must be labelled. Gluten-free foods can usually be recognised by the symbol of a crossed-out ear of corn.
