Which nutrient is often referred to as the forgotten nutrient and plays crucial roles in bodily functions?

Water is often referred to as the "forgotten nutrient" because, while it is essential for survival, it is frequently overlooked in discussions about nutrition. Unlike macronutrients such as proteins, carbohydrates, and fats, which are commonly emphasized in dietary guidelines, water's critical roles in the body are sometimes underestimated.

Water is vital for numerous bodily functions, including temperature regulation, transporting nutrients and oxygen to cells, aiding in digestion, and removing waste products. It also contributes to maintaining blood volume and pressure, lubricating joints, and acting as a shock absorber for organs. Given that the body comprises approximately 60% water, its importance cannot be understated.

In contrast, other nutrients like proteins, carbohydrates, and fats are often the focal point in nutrition discussions, as they directly provide energy and building blocks for the body's tissues. However, without adequate hydration, the body cannot effectively utilize these macronutrients, underscoring why water deserves as much attention as the other nutrients.
