Dietary options refer to the various types of food choices available to individuals based on their health needs, preferences, and ethical beliefs. Common dietary options include vegetarian, vegan, gluten-free, and paleo diets. Each of these options has specific guidelines about what foods can be consumed, often focusing on whole, unprocessed foods. People may choose a dietary option for various reasons, such as health benefits, weight management, or environmental concerns. For example, a vegan diet excludes all animal products, while a gluten-free diet eliminates foods containing gluten, which is important for those with celiac disease.
