Which group of nutrients is primarily responsible for providing energy?

Carbohydrates and fats are the primary sources of energy for the body. Carbohydrates are the body's preferred source of fuel, as they can be quickly broken down into glucose, which is then used by cells for energy. Fats, on the other hand, provide a concentrated source of energy, giving the body more than double the energy per gram compared to carbohydrates and proteins. This makes both carbohydrates and fats essential in a balanced diet for maintaining adequate energy levels.

While proteins can also provide energy, their primary role is to support growth and repair of tissues. Minerals and vitamins are crucial for various bodily functions, but they do not provide energy in the way that carbohydrates and fats do. Thus, the correct grouping that indicates the main source of energy is carbohydrates and fats.
