A macronutrient is a dietary component needed in relatively large amounts, while micronutrients are needed by the body in small quantities. Dietary sources of macronutrients include vegetable oils, fats, meat and poultry. Examples of micronutrients include vitamins, minerals and antioxidants that may be obtained from a diet high in fruits and vegetables.
The three primary macronutrients contained within food are fat (lipids), carbohydrate (or sugars), and protein. The human body includes all three macronutrients on its list of things it needs to survive, but individual people have different sensitivities to each type on the nutrient distribution scale from 5% for people with celiac disease who avoid gluten-containing food items. https://borates.today/boron-supply-developing/
