NUTRITION

Nutrition is the biological process in which organisms assimilate food and fluids necessary for operation, growth and maintenance of its vital functions. Nutrition is the study of the relationship between food and health, particularly in the determination of a diet. Although food and nutrition are often used interchangeably, are different terms as: Nutrition refers to the nutrients that make food and includes a set of involuntary events that occur after ingestion of food, ie digestion, absorption or passage of blood from the digestive tract of its components or nutrients, your metabolism or chemical transformations in cells and excretion or elimination of the organism. Nutrition is the science that examines the relationship between diet and health.Dietitians are health professionals who specialize in this area of study, and are trained to provide dietary advice. The supply includes a set of voluntary and conscious actions that are aimed at the choice, preparation and ingestion of food, phenomena closely related to sociocultural and economic environment (environment) and determine at least in large part, dietary habits and styles of life. Many common diseases and their symptoms can often be prevented or alleviated with good nutrition but things like eating fat, therefore, the science of nutrition attempts to understand how and what are the specific dietary aspects influence health. The purpose of nutrition science is to explain metabolic and physiological response of the body to the diet.With advances in molecular biology, biochemistry and genetics of nutrition science is further developed in the study of metabolism, which seeks to connect to the diet and health through the lens of biochemical processes. The human body is made of chemical compounds such as water, amino acids (proteins), fatty acids (lipids), nucleic acids (DNA / RNA) and carbohydrates (eg sugars and fiber). Proper nutrition is the cover: The requirements of energy through the metabolism of nutrients such as carbohydrates, proteins and fats. These energy requirements are related to basal metabolic expenditure, expenditure by physical activity and diet-induced spending. The non-energy needs of micronutrients such as vitamins and minerals. Proper hydration based on the consumption of beverages, especially water. The adequate intake of dietary fiber. The dietary goals are represented by different artwork, one of them is the food pyramid. Maria Castillo CI: 17,874,402 Section: 4m11E.I Retrieved Material: Encarta 2009

I've been searching about Nutrition and reading your blog, I found your post very helpful. I thought I would leave my first comment. I don't know what to say except that I have enjoyed reading. There are many doctores and hospitals which are working in this. I saw a website which really has some good content about Nutrition, I am pasting the link here http://www.corechiro.com
