Nutrition is the physiological and biochemical std test kit process by which an organism uses food to support its normal existence. It involves absorption, assimilation, degradation, biosynthesis, metabolization and excretion as well. It is a complete science that considers all these processes and their effects on health. It is practiced by the whole life sciences; it even has a part in medical nutrition therapy. This is also called the discipline of nutrition.
Good nutrition is essential to stay healthy. Some nutritional values include: the nutrients needed to develop and grow; maintenance of the status of the tissues and organs and energy required for activity. All the nutrients are important to the humans and they should be included in the diet as a source of nutrition. Nutritional value of food is measured in terms of nutrients quantity and quality. Nutrient mixture consists of vitamins, minerals, carbohydrates, fat, proteins and fats with selected essential nutrients and in some quantity of water or some other agent.
The main objective of nutrition is to provide the building blocks of life to the body. These building blocks are carbohydrates, proteins, fats and essential fatty acids. Carbohydrate can be considered as the most important nutrient because it is responsible for providing energy to the body. It is present in all foods and the only exception is foods that contain sugar as a main ingredient. It is found in such foods as pasta, cereals, breads, potatoes and various legumes. It is also found in milk and some dairy products like cheese and yoghurt.
In order to understand nutrition terms, we have to know what these building blocks are and how they are formed. Carbohydrates are the main source of energy and supply of carbohydrates to the body. The energy obtained from eating carbohydrates provides the body with the power it requires for carrying out different body functions and activities. Carbohydrates are available in plant foods and in foods that contain them in small quantities. Good nutrition terms for carbohydrates are complex and it is important to understand their structure and usage in order to obtain good nutrition.
Another type of nutrition is called heterotrophs or those that produce energy from the food plant by using complex enzymatic reactions. Heterotrophs are generally categorized as simple carbohydrates, complex carbohydrates and mixotrophs. A mixture of carbohydrates determines the level of overall health a person enjoys. This type of nutrition has to be combined with the appropriate mix of minerals, vitamins and proteins to achieve a balanced diet. Good nutrition will provide you with energy to carry you through the day without getting tired and gives your body with the energy it needs for its normal functioning.
Mixotrophs are present in a natural condition in plants. They form a protective layer on the surface of the cells that protect the cell from damage caused by oxygen and other nutrients. In the case of plant cell walls, heterotrophs act as a guard that stops foreign matters entering the cell. They also help in the absorption of other nutrients in the cell. In the case of the human body, mixotrophs and heterotrophs can be found in the bone marrow where they maintain the balance in the production and release of oxygen in the blood.
