Which of the following is a common dietary restriction?

Gluten intolerance is a common dietary restriction primarily due to health concerns related to the consumption of gluten, a protein found in wheat, barley, and rye. For individuals with celiac disease or non-celiac gluten sensitivity, ingesting gluten can trigger adverse reactions, leading to digestive issues, inflammation, and other health problems. This condition necessitates a strict avoidance of gluten-containing foods, making it a well-recognized dietary restriction in both medical and social contexts.

While veganism is also a significant dietary choice based on ethical or environmental beliefs, it is less commonly a restriction related to health issues. Ketosis is a metabolic state often achieved through a low-carbohydrate, high-fat diet which is more of a dietary strategy than a restriction. A high-protein diet focuses on macronutrient intake but does not restrict entire food groups like gluten or animal products. As a result, gluten intolerance stands out as a prevalent dietary restriction that affects many individuals’ food choices to maintain their health and well-being.
