Gluten-free diets involve avoiding foods containing gluten, a protein found in wheat, barley, rye, and their derivatives. People with celiac disease, gluten sensitivity, or wheat allergy often adopt gluten-free lifestyles. These diets typically include naturally gluten-free foods like fruits, vegetables, lean proteins, and gluten-free grains like quinoa or rice. Gluten-free alternatives such as almond or coconut flour are common in baking. While crucial for those with specific conditions, it’s essential to ensure a well-balanced diet, as gluten-free products may lack certain nutrients. Consultation with a healthcare professional or dietitian is advisable before making significant dietary changes.
