SCIENCE THAT STUDIES THE PHYSIOLOGICAL AND METABOLIC PROCESSES IN THE BODY
Dietary represents one of the cornerstones in the treatment of overweight. Obesity is a serious problem that has persisted since the last century, in which the changes in eating habits and life which are currently one of the current causes occurred. In the fight against it the approach at different levels, which is maintained over time, sometimes a definite change of incorrect eating habits is essential. Obesity is the result of an imbalance in time, generally between calorie intake and are spent. Generating a positive balance that accumulates in the body in areas of fatty tissue. |
The purpose of the science of nutrition is to explain metabolic and physiological response of the body to diet. With advances in molecular, biochemical and genetic biology, nutritional science focuses on the study of metabolism, investigating the relationship between diet and health from the point of view of the biochemical processes. The human body is made of chemical compounds such as water, amino acids , fatty acids , nucleic acids and carbohydrates .
All foods contain nutrients. These are: carbohydrate, fat, proteins.
With the help of minerals, vitamins and water, they become chemical compounds that cells use to live. There are 2 types of cellular and multicellular organisms called: Heterotrophs Autotrophic Many common diseases and their symptoms often can be prevented or alleviated with a certain power. therefore, the science of nutrition attempts to understand what specific dietary aspects influence health are.

The human body is made of chemical compounds such as water, amino acids , fatty acids , nucleic acids and carbohydrates . Proper nutrition is the covering:
Power requirements through the metabolism of nutrients like carbohydrates, proteins and fats. These energy requirements are related to the basal metabolic rate, spending on physical activity and diet-induced spending. Non-energy needs micronutrients such as vitamins and minerals. Proper hydration based on consumption of drinks, especially water. Sufficient intake of dietary fiber. |
Types of nutrition in living organisms. Autotrophic Nutrition is the holding bodies produce their own food. The autotrophs are organisms able to synthesize essential substances for their metabolism from inorganic substances. Autotrofo The term comes from greek and means that feeds itself . Autotrophic organisms produce their cell mass and organic matter from carbon dioxide as the sole carbon source, using light or chemicals for energy. Plants and other organisms that use photosynthesis are fotolitoautotrofos. They are utilizing bacteria oxidation of inorganic compounds such as sulfur dioxide or ferrous compounds as energy production are called quimiolitotroficos. Heterotrophic Nutrition is holding organisms that need others to live. Heterotrophic organisms from the greek ,hetero, another, uneven, different and trofo, which feeds, in contrast to autotrophs are those that must be fed with organic substances synthesized by other organisms, either autotrophic or heterotrophic to it turns. Among the crowd is heterotrophic bacteria and animals. |
Heterotrophic beings like animals, fungi, and most bacteria and protozoa depend on autotrophs because they use their energy and matter they contain to make complex organic molecules. Heterotrophs they obtain energy by breaking molecules autotrophs beings who have eaten. Even carnivorous animals rely on autotrophs because the energy and organic composition obtained from their prey comes ultimately from autotrophs beings who ate their prey.
Heterotrophs can be of two types mainly: consumers or saprotrophs and decomposers.
Autotrophic and heterotrophic need each other to exist.
There are many diets that range from the classic low-calorie diet with a balance between different types of nutrients in each meal, to the famous diets dissociated among which diets high protein intake. In these cases the strict monitoring of the patient by a doctor as well as periodic monitoring with blood tests is essential. Currently there is also the option of diets proteinadas support level shakes and pharmacologically to reduce the weight, a medical examination and a gradual change controlled metabolic and nutritional snacks. With significant reductions in weight, no shortness of sugar or depressive states that appear on other weight reduction processes, are being established as an important alternative simple calorie diet. ... read more |
