NUTRIENTS

“Nutrients are the compounds in food that provide us with energy that facilitates repair and growth and helps to carry out different life processes.”

Not all nutrients provide energy but are necessary for some form or the other.

There are various types nutrients :

Carbohydrates, or carbs, are sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks.
Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs.

Protein are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
Proteins are made up of building blocks called amino acids. There are about 20 different amino acids that link together in different combinations. Our body uses them to make new proteins, such as muscle and bone, and other compounds such as enzymes and hormones. It can also use them as an energy source.

Fats are also called 'fatty acids' or 'lipids. ' Fats in our body are made up of three molecules joined together. This three-molecule structure is called a “triglyceride”.
Most of the fat we need is made by our bodies, but there are some fats our bodies cannot make.

A vitamin is an organic molecule that are essential to an organism in small quantities for proper metabolic function.
Essential nutrients cannot be synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through the diet.
Vitamins are substances that our bodies need to develop and function normally. They include vitamins A, C, D, E, and K, choline, and the B vitamins.

A mineral is a natural substance with distinctive chemical and physical properties, composition, and atomic structure.
Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium.

Dietary fibre is found in wholegrain cereals and fruit and vegetables.
Fibre is made up of the indigestible parts or compounds of plants, which pass relatively unchanged through our stomach and intestines. Fibre is mainly a carbohydrate.
The main role of fibre is to keep the digestive system healthy.

Keep a normal temperature. Lubricate and cushion joints.
Protect your spinal cord and other sensitive tissues. Get rid of wastes through urination, perspiration, and bowel movements.
