 (măk′rō-no͞o′trē-ənt, -nyo͞o′-)
A substance required in relatively large amounts for the normal growth and development of an organism. Macronutrients for animals include fat, carbohydrate, and protein, while for most plants they include chemical elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus.


(Biochemistry) any substance, such as carbon, hydrogen, or oxygen, that is required in large amounts for healthy growth and development


(ˌmæk roʊˈnu tri ənt, -ˈnyu-)

1. any of the nutritional components required in relatively large amounts: protein, carbohydrate, fat, and the essential minerals.
2. any of the chemical elements required by plants in relatively large amounts: nitrogen, phosphorus, and potassium.

Food addiction was assessed using the Yale Food Addiction Scale and the macronutrient intake was determined from the Willet Food Frequency Questionnaire.
A variety of medical specialists from the US and Canada, working in fields like cardiovascular disease, psychiatry, and nutrition, discuss the metabolic factors and related diseases that contribute to cardiovascular disease; key metabolic pathways including lipid and lipoprotein metabolism, macronutrient fuel partitioning, insulin action, and body weight regulation; the mechanisms that relate to obesity, maintenance of the obese state, the dyslipidemias, and glucose intolerance/diabetes; and interventions that can reduce metabolic risk factors.
The unique macronutrient profiles are supplemented with vitamins and minerals to ensure adequate intake, while supporting protein synthesis, energy production and fat utilization.
