Nutrients For Our Body

Human consumed foods contain various elements. There are elements that are useful and some are not beneficial for health. Various substances in foods can be enzymes, nutrients, or toxins. An element of nutrients contained in foods that provide health benefits for our bodies. Each consumed foods contain different nutrients. The difference may be the type of nutrients contained in food, as well as the amount of each nutrient. One type of specific nutrients may have on type of food, but it could be possible nutrients are not present in other foodstuffs.

For one type of certain nutrients, may be more contained to one type of food, but there could be no at all other foods. Also certain amount of nutrients found in significant amounts in one types of food, but could be found only in very small amounts in other foods. Therefore so that the body is not one of lack of nutrients, then we should not depend on one type of food alone, but should consume a variety of food types.

Nutrients are classified based on several things, which is based on function, based on the amount needed by the body and based on its source:

1. based on the function. Each nutrient has specific functions. Each of these nutrients can not stand alone in body build and run the metabolic process. However, these nutrients have different functions.
• Nutrients as a source of energy. Our body gets energy from nutrients beneficial for our activity and metabolic processes. Nutrient substances belonging to the function gives the energy is carbohydrates, fats and proteins. Food that serves as a source of energy such as: rice, corn, wheat and sweet potatoes are a source carbohydrate; margarine and butter is a source of fat; fish, meat, eggs are a source of protein. These three nutrients provide energy for body donation. These nutrients are producing energy that can be used for movement and physical activity and metabolic activity in the body. But the largest contributor to energy the third element of these nutrients is fat.
• Nutrients for growth and maintain body tissue. These nutrients function as the cells forming the tissue. If the deficiency is to consume the nutrients and the growth of human development will be retarded. Besides these nutrients also serve to replace cells damaged and maintain organ function. Nutrients included in this group are proteins, fats, minerals and vitamins. However, nutrients that have a source dominant in the growth process are a protein.
• Nutrients as regulators / regulatory processes in the body. Metabolic processes in the body needs in order arrangements balance occurs. For that amount of nutrients needed to manage ongoing metabolism in the body. In our bodies also need to balance, to the metabolic processes that occur in the body needs to be set properly. Nutrients that function to regulate metabolic processes in the body are minerals, vitamins, water and protein. But the main function is regulating substances as minerals and vitamins.
  
2. Based on quantity. Raw foods contain nutrients that your body needs based on the quantity divided into two, namely:
• Macro nutrients are nutrients needed in large quantities with unit’s gram. Nutrients including the macro nutrients are carbohydrates, fats and proteins.
• Micro nutrients are nutrients the body needs in small amounts or small but in food. Nutrients including micro nutrients group are minerals and vitamins. Micro nutrient use the unit mg for mineral and vitamin content.
  
3. Based Sources. The food we eat everyday can be distinguished by its source, namely:
• Vegetable sources are nutrients that we get from plants such as vegetables and fruits.
• Animal sources are derived nutrients the body from food of animal origin such as meat, fish, and eggs.
