Over 99% of blood is composed of water, a substance with zero calories that is not considered a nutrient, yet is vital for survival. Understanding what isn't a nutrient is key to appreciating the complex interplay of all the substances in our food, both nutritive and non-nutritive, that support our bodily functions.

Over 20 amino acids serve as the building blocks for proteins in the human body. This fundamental biological fact is key to understanding the difference between the essential and non-essential amino acids in Quizlet study sets, a popular method for memorizing these important classifications. The core distinction lies in whether the body can synthesize them or if they must be obtained through your diet.

By definition, an essential nutrient is one that the body cannot produce sufficiently on its own and must obtain from food. However, when asking if glucose is an essential nutrient, the answer is more complex due to the body's remarkable ability to synthesize it from other sources. This process, called gluconeogenesis, is critical for survival.

Bioactive compounds, like those found in plants, can improve human health by modulating biological processes, even though the body can function without them, unlike essential nutrients. While both offer health benefits, their core roles, requirements, and sources differ significantly, a distinction that is key to understanding modern nutrition.

The human body can synthesize the majority of fatty acids it requires from other nutrients, such as carbohydrates and proteins. These internally produced fats, unlike their dietary counterparts, are classified as the fatty acids that are not essential.
