Gluten-free diet – benefits, products & tips

In a world where more and more people are rethinking their eating habits and looking for healthier alternatives, the gluten-free diet is becoming increasingly important. But what exactly does it mean to eat gluten-free and why is it more than just a trend for some people? Gluten, a protein found in many grains, can cause serious health problems for people with coeliac disease or gluten intolerance. For them, a gluten-free diet is not a choice, but a necessity to avoid ailments such as gastrointestinal discomfort, skin rashes and fatigue. But a gluten-free diet is not only important for people with gluten intolerance. More and more people are consciously choosing to eliminate gluten from their diet to improve their overall health, reduce digestive problems or boost their energy levels.

What is gluten?

Gluten is a protein found in various cereals, especially wheat, barley, rye and their derivatives. It consists of two main protein groups: Gliadin and glutenin. These proteins are responsible for the elastic structure of dough and give baked goods such as bread, cakes and pasta their characteristic consistency.

For most people, gluten is harmless and an important source of protein in their diet. However, gluten can cause serious health problems for people with coeliac disease, an autoimmune disorder, or gluten intolerance.

In people with coeliac disease, eating gluten triggers an immune response that leads to inflammation in the intestines. This can lead to damage to the intestinal wall and impair the absorption of nutrients. In the long term, untreated coeliac disease can lead to serious health complications such as nutritional deficiencies, osteoporosis and even bowel cancer.

Gluten intolerance, also known as non-celiac gluten sensitivity, is a less severe form of gluten intolerance. People with gluten intolerance experience symptoms similar to those of coeliac disease, but without the characteristic immune reactions and damage to the intestinal wall. The exact causes and mechanisms of gluten intolerance are not yet fully understood, but many people report an improvement in their symptoms on a gluten-free diet.

In the next sections, we will take a closer look at how gluten-free diets can help people with coeliac disease and gluten intolerance to improve their health, and why more and more people are choosing a gluten-free diet even without a diagnosed gluten intolerance.

Coeliac disease and gluten intolerance

Celiac disease and gluten sensitivity are two distinct disorders caused by intolerance to gluten, but they have different effects on the body.

Celiac Disease: Celiac disease is an autoimmune condition in which the body’s immune system perceives gluten as a threat and triggers an immune response. This reaction results in inflammation of the lining of the small intestine, which can damage the intestinal villi. This impairs the body’s ability to absorb nutrients from food, leading to a range of symptoms and long-term complications. Symptoms of celiac disease include:

• Abdominal pain
• Bloating
• Diarrhea
• Weight loss
• Fatigue
• Anemia
• Skin rash (Dermatitis herpetiformis)

Gluten Sensitivity: Gluten sensitivity, also known as non-celiac gluten sensitivity, is a less severe condition in which people experience symptoms similar to those of celiac disease without exhibiting the characteristic intestinal damage or immune response. Symptoms of gluten sensitivity include:

• Abdominal pain
• Bloating
• Diarrhea
• Headaches
• Fatigue
• Joint pain

It’s important to note that some people with celiac disease or gluten sensitivity may have no symptoms, which can make diagnosis challenging.

Diagnosis and Testing

Diagnosing celiac disease and gluten sensitivity typically requires a combination of clinical evaluations, blood tests, and a small intestine biopsy. Blood tests include the tissue transglutaminase antibody (tTG-IgA) test and the endomysial antibody (EMA-IgA) test. A small intestine biopsy can help confirm damage to the intestinal villi, which is characteristic of celiac disease. For gluten sensitivity, other tests may be conducted to rule out other possible causes of the symptoms.

Foods that contain gluten

Gluten is present in many types of grains that are commonly found in our diet. Here is an overview of the main grains containing gluten, as well as examples of foods and products that may contain gluten:

1. Grains containing gluten:

• Wheat
• Barley
• Rye
• Spelt
• Kamut
• Triticale (a hybrid of wheat and rye)

2. Foods and products that may contain gluten:

• Bread and baked goods: White bread, whole wheat bread, baguettes, rolls, croissants, pastries, cakes, cookies, cereal bars
• Cereal products: Oats (if not explicitly labeled as gluten-free), muesli, breakfast cereals, couscous, bulgur, barley groats

The benefits of a gluten-free diet

A gluten-free diet can offer various health benefits, especially for people with celiac disease, gluten intolerance, or certain health conditions. Here are some of the potential benefits of a gluten-free diet:

Health benefits of a gluten-free diet:

• Reduced risk of gastrointestinal discomfort: For people with celiac disease or gluten intolerance, avoiding gluten can help alleviate symptoms such as abdominal pain, bloating, diarrhea, or constipation, and improve digestive system health.
• Anti-inflammatory effects: Some studies suggest that a gluten-free diet may have anti-inflammatory properties, which can be particularly beneficial for people with inflammatory conditions such as rheumatism, arthritis, or inflammatory bowel disease.
• Potential improvement of autoimmune diseases: In some people with autoimmune diseases such as Hashimoto’s thyroiditis or rheumatoid arthritis, a gluten-free diet may help reduce inflammation and alleviate symptoms, although further research is needed to confirm this association.

Improvement of digestive problems and gastrointestinal discomfort:

• Reduced discomfort in people with celiac disease or gluten intolerance: Avoiding gluten can help alleviate digestive problems such as abdominal pain, bloating, diarrhea, or constipation, and improve quality of life.
• Better nutrient absorption: People with celiac disease or gluten intolerance often suffer from impaired nutrient absorption due to damage to the intestinal villi. A gluten-free diet can repair this damage, leading to improved absorption of nutrients such as iron, calcium, vitamin B12, and other essential nutrients.

Potential effects on energy levels, skin health, and weight management:

• Increased energy levels: Some people report an increase in energy levels and improved overall vitality after transitioning to a gluten-free diet.
• Better skin health: For some individuals, a gluten-free diet may help reduce skin problems such as acne, eczema, or psoriasis, and improve skin health.
• Support for weight management: For some people, a gluten-free diet may help with weight loss or maintaining a healthy weight, especially if they have previously suffered from digestive problems caused by gluten.

However, it is important to note that a gluten-free diet is not suitable for everyone and is not automatically healthier than a balanced diet that includes gluten. People considering a gluten-free diet should discuss this with a doctor or dietitian to ensure they receive all necessary nutrients and avoid deficiencies or health issues.
