Understanding Celiac Disease and Gluten Sensitivity
Navigating the complexities of celiac disease and gluten sensitivity is critical for adopting a successful gluten-free Mediterranean diet. Understanding these conditions and their symptoms can lead to better dietary choices and improved health.
What Is Celiac Disease?
Celiac disease is an autoimmune disorder where the ingestion of gluten leads to damage in the small intestine. Gluten, a protein found in wheat, barley, and rye, triggers an immune response in people with celiac disease. This response damages the microvilli, which are tiny hair-like projections in the small intestine responsible for nutrient absorption. A definitive diagnosis often requires a combination of serologic tests for specific antibodies and a biopsy of the small intestine.
Non-Celiac Gluten Sensitivity
Non-celiac gluten sensitivity (NCGS) involves a negative reaction to gluten that is not autoimmune like celiac disease. Individuals with NCGS experience symptoms similar to celiac disease but typically without the intestinal damage. Unlike celiac disease, there are no specific biomarkers, like antibodies or intestinal damage, that can reliably diagnose non-celiac gluten sensitivity.
Identifying Symptoms of Gluten Intake
Symptoms of both celiac disease and gluten sensitivity can include, but are not limited to, gastrointestinal issues such as diarrhea, constipation, and bloating, as well as non-GI symptoms like headaches and fatigue. These symptoms can vary greatly in presentation and severity. A gluten-free Mediterranean diet, avoiding gluten-containing grains such as wheat, barley, and rye, can help manage these symptoms and promote gut health.
Basics of a Gluten-Free Diet
Adopting a gluten-free diet primarily involves eliminating gluten, a protein complex found in certain grains, to manage health issues like celiac disease. This section will provide an understanding of what constitutes a gluten-free diet and guidance on foods to include and avoid.
Defining Gluten-Free
A gluten-free diet excludes all forms of gluten, typically found in wheat, barley, and rye.
