1. Which of the following are energy foods?(a) Carbohydrates and fats(b) Proteins and mineral salts(c) Vitamins and minerals(d) Water and roughage

To determine which of the options are energy foods, let's analyze each option:

(a) Carbohydrates and fats: Carbohydrates and fats are indeed energy foods. When consumed, they are broken down by the body into glucose and fatty acids, respectively, which are then used as a source of energy.

(b) Proteins and mineral salts: While proteins are essential for building and repairing tissues, they are not primarily considered energy foods. Mineral salts, on the other hand, do not provide energy.

(c) Vitamins and minerals: Vitamins and minerals are important for various bodily functions, but they do not directly provide energy.

(d) Water and roughage: Water and roughage, such as dietary fiber, are not energy foods. However, they play a crucial role in maintaining proper digestion and overall health.

Based on the above analysis, the correct answer is (a) Carbohydrates and fats.
