Gluten is a protein found in wheat, barley, and rye. While it does not pose a problem for most people, those with celiac disease, gluten intolerance, or sensitivity need to follow a gluten-free diet to avoid health problems.
In this article, we take a closer look at the link between gluten-free diets and health.
Celiac Disease, Gluten Intolerance, and Sensitivity
Celiac disease is an autoimmune disorder triggered by the ingestion of gluten. The immune system attacks the small intestine, damaging the villi that absorb nutrients.
The symptoms of celiac disease are varied and can include diarrhea, abdominal pain, bloating, weight loss, and fatigue. It is estimated that 1% of the population has celiac disease.
Gluten intolerance or non-celiac gluten sensitivity is a condition that causes similar symptoms to celiac disease, but without the damage to the small intestine. The symptoms are less severe, but can still interfere with daily life.
It is estimated that up to 6% of the population has non-celiac gluten sensitivity.
The Gluten-Free Diet
A gluten-free diet eliminates all products that contain gluten, including bread, pasta, cereals, beer, and baked goods. Gluten-free alternatives are available but can be more expensive and have a different taste and texture.
A gluten-free diet requires careful label reading and meal planning.
The gluten-free diet is the only treatment for celiac disease and gluten intolerance.
When followed strictly, it can lead to a significant improvement in symptoms, the healing of the intestine, and a reduced risk of complications such as cancer or osteoporosis.
Health Benefits of a Gluten-Free Diet
Improved Digestive Health
For people with celiac disease or gluten intolerance, a gluten-free diet can relieve digestive symptoms such as bloating, gas, and diarrhea. It can also improve nutrient absorption and prevent malnutrition caused by the damage to the small intestine.
Reduced Inflammation
Gluten is believed to trigger an inflammatory response in some people, even those without celiac disease or gluten intolerance. Inflammation is linked to many health problems, including arthritis, autoimmune disorders, and cardiovascular disease.
A gluten-free diet can reduce inflammation and improve overall health.
Reduced Risk of Type 2 Diabetes
A gluten-free diet may reduce the risk of developing type 2 diabetes, especially in people with celiac disease or gluten intolerance.
A study published in the Journal of Diabetes Science and Technology found that a gluten-free diet improved glycemic control and insulin sensitivity in people with type 1 diabetes.
Weight Loss
A gluten-free diet can lead to weight loss, especially in people with celiac disease or gluten intolerance who had unexplained weight gain.
When the intestine is damaged, the body cannot absorb nutrients properly, leading to malnutrition and weight gain. A gluten-free diet can improve nutrient absorption and promote weight loss.
Possible Risks of a Gluten-Free Diet
Nutrient Deficiencies
A gluten-free diet can lead to nutrient deficiencies if not followed carefully. Gluten-free products are often low in fiber, iron, calcium, and B vitamins.
This can be especially problematic for people with celiac disease or gluten intolerance, who may already have nutrient deficiencies due to malabsorption.
Higher Costs
Gluten-free products are often more expensive than their gluten-containing counterparts. This can make it difficult for people on a budget or people who live in areas without access to gluten-free products.
Conclusion
A gluten-free diet is essential for people with celiac disease or gluten intolerance. It can improve symptoms, prevent complications, and improve overall health.
For people without gluten-related disorders, a gluten-free diet is unnecessary and may even be harmful if not followed carefully. It is always important to talk to a healthcare provider or registered dietitian before making any significant dietary changes.
