What term is used for nutrients that must be obtained from food because the body cannot produce enough on its own?

The term that refers to nutrients the body cannot produce in sufficient quantities and must therefore be obtained through the diet is essential nutrients. These nutrients play critical roles in various bodily functions, including growth, metabolism, and overall health. Essential nutrients include certain amino acids, fatty acids, vitamins, and minerals that the body requires for optimal functioning but cannot synthesize in adequate amounts on its own.

In contrast, macronutrients encompass carbohydrates, proteins, and fats, which are needed in larger quantities to provide energy and support physiological functions. Micronutrients, on the other hand, refer to vitamins and minerals that the body needs in smaller amounts but are still crucial for maintaining health. Non-essential nutrients are those that the body can produce independently; therefore, they are not required to be consumed through the diet. Understanding the distinction between these terms is fundamental in nutrition science, as it highlights the importance of dietary intake for maintaining health and preventing deficiencies.
