A macronutrient and concentrated source of dietary energy that also carries the fat-soluble vitamins; found in oils, nuts, seeds, dairy, and meats.

Commonly noted

Commonly noted: Fat is a macronutrient that provides a concentrated source of energy, helps the body absorb the fat-soluble vitamins A, D, E, and K, and forms part of every cell membrane; dietary fat is a mix of saturated, monounsaturated, and polyunsaturated types.
Low intake: Very low fat intake is commonly discussed in relation to trouble absorbing fat-soluble vitamins and, over time, dry skin, though a shortfall is uncommon on a typical diet.
Higher intake: Because fat is the most energy-dense macronutrient, large amounts are commonly discussed in relation to overall daily energy intake.
