Nutritional practices have evolved significantly throughout history. Ancient civilizations, such as the Egyptians and Greeks, recognized the importance of food in sustaining life and health. Early dietary philosophies often intertwined with cultural and religious beliefs, shaping regional diets and culinary traditions.
Origins of Modern Dietary Guidelines
The concept of dietary guidelines began to formalize in the early 20th century, influenced by pioneering nutritionists and scientists. Key figures like Dr. Wilbur Olin Atwater in the United States and Dr. Max Rubner in Germany laid the foundation for understanding macronutrients and caloric intake.
