A Review of the Gluten-Free Diet
The gluten-free diet eliminates all forms of gluten, a protein found in wheat, barley, rye, and their derivatives. It is essential for certain medical conditions and increasingly popular as a lifestyle choice. Here’s an in-depth look:
Who Needs a Gluten-Free Diet?
- Celiac Disease
- An autoimmune condition where gluten triggers intestinal damage.
- Requires complete elimination of gluten to prevent complications.
- Non-Celiac Gluten Sensitivity (NCGS)
- Individuals experience symptoms like bloating, fatigue, and brain fog after consuming gluten but do not have celiac disease or a wheat allergy.
- Wheat Allergy
- A true food allergy to wheat proteins (not limited to gluten).
