When you find a nutritionist or a nutritional therapist it would be useful to understand how it works or can help you. Nutrition is the process of nutrients being taken in (usually as food substances) and the body then making use of them. By identifying the different types and amounts of nutrients needed for growth and health, a balanced diet can be used to promote healthy living and reduce the chances of developing diseases. Nutrients are generally divided into five groups: proteins, carbohydrates, fats, minerals and vitamins, with water as the sixth essential element to a healthy body.
Proteins are essential for repairing tissue and cells and are made up of amino acid combinations. They can be found in meat, eggs and oily fish or as plant protein in cereal, nuts and seeds among others. Carbohydrates are found in foods such as bananas, nuts and potatoes and are used as energy food by the body. Fats are needed for healthy skin and hair, protecting internal organs and preventing heat loss. It is also used for energy and identified by either saturated or unsaturated fat.
Minerals and vitamins are found in food but can be taken as supplements. Minerals, such as calcium and iron, help vitamins to work. Vitamin D for instance is found in foods like milk and eggs and aids the absorption of calcium in the body to strengthen bones and teeth.
As the body is 75% water, it is a vital element needed for the body to exist. Water helps in removing waste products from the body, transporting minerals and oxygen around the body and regulating body temperature. Dehydration from lack of water causes headaches, sickness and over a prolonged period death. The body can't function properly without water for more than a couple of days and as it can't be stored, must be replaced on a regular basis.
