Define essential nutrients in nutrition

Nutrients (including vitamins) that the body cannot synthesize endogenously, or cannot synthesize in sufficient quantities, and therefore must be obtained through dietary intake are classified as "essential."

Evaluate the given options

• "vital" and "necessary" are general descriptors but not the formal nutritional classification term.
• "essential" is the standard scientific term for nutrients that must be consumed because the body cannot synthesize them.
• "extraneous" means irrelevant or external, which is incorrect.
