Dietary needs refer to the specific nutritional requirements of an individual based on factors such as age, health status, and lifestyle. These needs can vary widely; for example, children require more calories and nutrients for growth, while older adults may need fewer calories but more vitamins and minerals. Certain medical conditions, like diabetes or celiac disease, can also dictate specific dietary restrictions. People with diabetes may need to monitor their carbohydrate intake, while those with celiac disease must avoid gluten. Understanding and addressing these dietary needs is essential for maintaining overall health and well-being.
