Step-by-step explanation:
Food exchange systems are tools designed for managing dietary intake, especially for individuals with diabetes. They categorize foods into groups based on similar nutrient content, allowing for flexible meal planning while maintaining consistent carbohydrate, protein, and fat intake for better blood sugar control.
Food exchange systems were originally developed for people with specific health issues or dietary restrictions, such as those with diabetes, cardiovascular disease, or food allergies. These systems help people manage their diets by providing a framework for balancing nutrients from different food groups. Additionally, food exchange systems are used by vegetarians, vegans, and individuals who choose to avoid certain food groups for personal or ethical reasons.
