Final answer:
Nutritionists developed AMDRs to optimize health and prevent chronic diseases in the context of modern lifestyles, providing quantitative nutrient intake guidance and promoting a balance between food intake and energy expenditure.
Step-by-step explanation:
Nutritionists developed Acceptable Macronutrient Distribution Ranges (AMDRs) to provide guidance on the intake of carbohydrates, proteins, and fats to optimize health and prevent chronic diseases. With changes in lifestyle and the advent of food abundance, concerns have shifted from undernutrition to overnutrition, leading to an increase in obesity and related health issues such as type-2 diabetes and cardiovascular diseases. The development of AMDRs is part of evidence-based nutrition that aims to balance food intake, energy storage, and expenditure through a diet rich in nutrients while also addressing the importance of maintaining an overall healthy lifestyle including exercise and stress reduction.
AMDRs are part of Dietary Reference Intakes (DRIs), providing quantitative advice to professionals about the amounts of nutrients or food components that benefit health. They help people make better dietary choices in the context of a balanced diet and are tailored to suit various life stages and conditions, ensuring that all individuals receive adequate nutrition according to their specific needs.
