Macronutrients

Macronutrients (/mækroʊˈnjuːtriənts/) are the nutrients that the human body needs in large amounts for energy and growth. They include carbohydrates, proteins, and fats. The term "macronutrients" is derived from the Greek words "makros" meaning large and "nutrient" meaning nourishing.

Carbohydrates

Carbohydrates (/kɑːrboʊˈhaɪdreɪts/) are the body's main source of energy. They are broken down into glucose, which is used by the body's cells for energy. The term "carbohydrate" comes from the Greek words "saccharon" meaning sugar and "hydor" meaning water.

Proteins

Proteins (/ˈproʊtiːnz/) are essential for growth and repair of body tissues. They are made up of amino acids, which are the building blocks of the body. The term "protein" is derived from the Greek word "proteios" meaning primary or holding the first place.

Fats

Fats (/fæts/) are a concentrated source of energy and are necessary for the absorption of certain vitamins. They also provide insulation and protection for organs. The term "fat" comes from the Old English "fætt" meaning crammed or stuffed.
