Nutrients are compounds in foods essential to life and health, providing us with energy, the building blocks for repair and growth and substances necessary to regulate chemical processes. There are six major nutrients: Carbohydrates (CHO), Lipids ( fats ), Proteins, Vitamins, Minerals, Water.
There are seven main classes of nutrients that the body needs. These are carbohydrates, proteins, fats, vitamins, minerals, fibre and water.
nutrient A vitamin, mineral, fat, carbohydrate or protein that a plant, animal or other organism requires as part of its food in order to survive. organism Any living thing, from elephants and plants to bacteria and other types of single-celled life.
Nutrients are the constituents in food that must be supplied to the body in suitable amounts. These include carbohydrates, proteins, fats, minerals, vitamins, water and fibre.
Nutritionists spend a lot of time discussing total digestible nutrients, minerals, crude protein and even various fractions of protein. However, we often take for granted the most important nutrient, the one required in the greatest amount by any class of livestock water.
While there are many essential nutrients, they can be broken into two categories: macronutrients and micronutrients.

Macronutrients include water, protein, carbohydrates, and fats. Keep reading for more information about where to find these nutrients, and why a person needs them. The six essential nutrients are vitamins, minerals, protein, fats, water, and carbohydrates.
|Nutrient||Use in the body|
|Protein||For growth and repair|
|Lipids (fats and oils)||To provide energy. Also to store energy in the body and insulate it against the cold.|
|Minerals||Needed in small amounts to maintain health|

A healthy diet throughout life promotes healthy pregnancy outcomes, supports normal growth, development and ageing, helps to maintain a healthy body weight, and reduces the risk of chronic disease leading to overall health and well-being.
Nutrients have one or more of three basic functions: they provide energy, contribute to body structure, and/or regulate chemical processes in the body. These basic functions allow us to detect and respond to environmental surroundings, move, excrete wastes, respire (breathe), grow, and reproduce.
It is concluded that O2 is an important nutrient, and indeed an essential one, that is required in large quantities and which should be considered in conjunction with what are conventionally regarded as nutrients. As such, O2 should be firmly viewed as being part of the landscape of nutritional science.
Types of Nutrients Macronutrients. Micronutrients.
Vitamins help in protecting our body against diseases. Vitamins also help in keeping our eyes, bones, teeth and gums healthy. Vitamins are of different kinds known by different names. Some of these are Vitamin A, Vitamin C, Vitamin D, Vitamin E and K.
Processes. Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
