Which of the following grains is allowed in a gluten-free diet?

Rice is allowed in a gluten-free diet because it does not contain gluten, a protein found in wheat, barley, rye, and some oats that can trigger adverse reactions in individuals with celiac disease or gluten sensitivity. Rice, being naturally gluten-free, can be a staple carbohydrate source for those avoiding gluten. Additionally, it is versatile and found in many culinary traditions, making it an excellent choice for gluten-free recipes and meals.

Wheat, oats, and rye all contain gluten, making them unsuitable for individuals who must adhere to a gluten-free diet. While oats are often considered gluten-free when processed correctly, they can frequently be cross-contaminated with gluten during processing, which can pose a risk for those with gluten sensitivities.
