Nutrients

Nutrients (/njuːˈtriːənts/) are substances used by an organism to survive, grow, and reproduce. The term "nutrient" comes from the Latin word nutrire, meaning "to feed, nourish".

Types of Nutrients

There are six major types of nutrients that the body needs to function properly: carbohydrates, proteins, fats, vitamins, minerals, and water.

  • Carbohydrates (/kɑːrboʊˈhaɪdreɪts/) are the body's main source of energy. They are broken down into glucose, which can be used immediately for energy or stored in the body's cells for later use.
  • Proteins (/ˈproʊtiːnz/) are essential for building and repairing tissues, making enzymes, and supporting immune function.
  • Fats (/fæts/) are a concentrated source of energy and are necessary for absorbing certain vitamins.
  • Vitamins (/ˈvaɪtəmɪnz/) are compounds that are necessary for normal growth and function. They are involved in many processes in the body, including the immune system, nervous system, and metabolic processes.
  • Minerals (/ˈmɪnərəlz/) are elements that are essential for the body's growth, development, and health. They are involved in many processes in the body, including bone health, fluid balance, and muscle function.
  • Water (/ˈwɔːtər/) is essential for many functions in the body, including digestion, absorption, circulation, and maintenance of body temperature.

Importance of Nutrients

Nutrients are essential for the body's overall health. They provide the body with energy, help to repair and build tissues, support the immune system, and aid in the absorption of other nutrients. Without proper nutrition, the body cannot function properly, leading to poor health and disease.

Related Terms

  • Malnutrition (/ˌmalnuːˈtrɪʃən/) is a condition that results from eating a diet in which one or more nutrients are either not enough or are too much such that it causes health problems.
  • Dietary Supplements (/ˈdaɪətɛri ˈsʌplɪmənts/) are products designed to augment your daily intake of nutrients, including vitamins and minerals.
