Which nutrient class makes up the greatest proportion of body weight?

The correct answer is water.

Nutrients are minerals, vitamins, proteins, carbohydrates, water, and fats. These six essential nutrients are important for each and every individual for energy, growth, and for repair and maintenance of the cells. Consuming a well-balanced diet with a broad variety of foods offers one the right amount of all the nutrients.

Water is the nutrient that forms about 60 percent of the weight of the body. It is essential for each cell in each of the tissue in the body. Water mediates other nutrients to each part of the body, it transports waste out of the body and it assists in monitoring the temperature of the body.
