According to nutrition guidelines, what should the majority of your daily energy intake come from?

The majority of daily energy intake should come from carbohydrates, as they are the primary source of energy for the body. Carbohydrates break down into glucose, which is the preferred fuel for the brain and muscles during physical activity. Guidelines from health organizations support a diet where carbohydrates, primarily from whole grains, fruits, and vegetables, constitute a significant portion of total caloric intake. This is because carbohydrates not only provide energy but also offer essential nutrients, fiber, and phytochemicals that promote overall health.

In contrast, while fats and proteins are important macronutrients, they play different roles in the body. Fats are crucial for hormone production and nutrient absorption, but they are more calorie-dense and should make up a smaller percentage of total caloric intake compared to carbohydrates. Proteins are vital for tissue repair and growth but also do not serve as the main energy source for the body in the same way carbohydrates do. Vitamins, while essential for various bodily functions, do not provide energy themselves. Therefore, the correct answer emphasizes the importance of carbohydrates as the foundation of a balanced diet according to nutrition guidelines.
