What are the three major nutrients essential for the body?

1. Vitamins, Minerals, Proteins

2. Carbohydrates, Fats, Proteins

3. Fats, Sugars, Water

4. Carbohydrates, Vitamins, Fats

The correct answer is: Carbohydrates, Fats, Proteins

The three major nutrients essential for the body are carbohydrates, fats, and proteins. These macronutrients play vital roles in maintaining overall health. Carbohydrates serve as the body's primary source of energy. They are found in foods such as grains, fruits, and vegetables, and are broken down into glucose, which is utilized by the body for energy to fuel physical activity and support vital functions. Fats are another crucial source of energy and are necessary for absorbing certain vitamins (A, D, E, and K) and providing essential fatty acids that the body cannot produce on its own. They play a key role in hormone production and the maintenance of cell membranes, contributing to overall health and well-being. Proteins are vital for building and repairing tissues, as well as for the production of enzymes and hormones. They are made up of amino acids, some of which are essential and must be obtained through diet. In contrast, while vitamins and minerals (mentioned in the first option) are important for various bodily functions, they are not classified as major nutrients since they are needed in smaller amounts compared to the macronutrients. Similarly, sugars and water (included in another option) are important for health, but sugars are actually a type of carbohydrate and water
