Within nutrition should emphasize the role of hydration. Eating the right amount of liquid daily, in addition to quench thirst, improve hydration levels, regulates the functioning of cells, favors the transport of nutrients, improves the lubrication of joints and helps maintain body temperature.

Each individual has specific needs hydration, depending on factors such as age, sex, metabolism, physical activity level and environmental conditions. These needs are increasing in certain populations like the elderly, children or athletes.

The elderly, children and adolescents are especially vulnerable to the consequences of dehydration, as in the case of the major mechanism of detection and identification of thirst is impaired, while in a sense children not yet sufficiently developed. Therefore, it is necessary to control these groups ingested a sufficient amount of fluid, even without being thirsty.

It is necessary to drink before you are thirsty. Only the body to lose 1% of liquid appears the feeling of thirst, if this loss is 2%, output decreases and the resistance and from 5% can produce a rapid heartbeat, listlessness, vomiting and muscle spasms.

During the summer, it becomes necessary to accompany the changes to adapt to the high temperatures required by the body with a power chord. Sweating is the main defense mechanism that the body mounts an operation against the elevation of body temperature. Its most obvious is the loss of water, however, this process also loses minerals such as sodium, potassium and magnesium, essential for a balanced body functioning.

It is therefore recommended to include as many drinks as possible to promote the total fluid intake. For healthy people, depending on age and physical activity, besides water, is recommended to consume tea, soft drinks, juices and milk, among others. This can help achieve the necessary daily amount of liquid.

Hydration with water must be accompanied by the consumption of fruits and vegetables to provide this additional requirement of minerals. Potassium is present in the banana and tomato, citrus being an excellent source of magnesium.

Alcoholic beverages, even those of low rank, are not the best choice for good hydration. Alcohol has a diuretic effect, which is why increases water loss through urine.

As a rule for every kilo of body weight required 31.5 ml of water, increasing their consumption slightly increased temperatures (daily pint more would suffice).

For athletes, adequate hydration is essential when developing any type of physical activity and good dehydration during and after it. During exercise may disappear thirst, but this does not mean that the body is hydrated. The lack of fluids can increase fatigue, degrade performance or cause heat stroke by reducing the body’s thermoregulatory capacity. Therefore, a good tip is to weigh you before and after exercise and eat a quantity of liquid equal to 1.5 times the weight off.

An international investigation involving reinvestigations Superior Council (CSIC) has managed to decipher the genome of bifid bacterium bifida, intestinal bacteria with robotic characteristics. The study further shows that this bacterium is able to extract nutrients from the mucking, a glycoprotein present in the intestinal mucosa. The work has been published in the latest issue of the journal ‘PNAS’. As explained by researchers at the CSIC and Borax Margoles Abelard Sanchez, “until now considered that the degradation of intestinal mucus no robotic was desirable because it could damage the mucosa. However, Bifid bacterium bifida PRL2010 is able to acquire nutrients from the degradation of glycols (compounds consisting of one or more sugars) present in the intestinal mucking, a glycoprotein that acts as a lubricant and protector of the gastrointestinal mucosa. “In normal physiological conditions, the human mucking has a high turnover rate.

The study shows how some bifid bacteria such as Bifid bacterium bifida PRL2010 can take advantage of this fact and incorporate catabolism of the degradation products of these polymers so complex without damaging the host, “explains Margoles, the Dairy Institute Asturias. Para conducting the study, researchers have used proteomic techniques and genetic analysis of transcription has identified several groups of genes regulated in a coordinated manner and present in the metabolism of medina.

Posteriormente found that these groups were highly conserved in different strains bacteria of the same species, indicating that the catabolism of these glycols is an important colonization factor for them. “This is one of the few studies that show that some bacteria are able to use mucking as an energy source”, adds Margoles. “It also gives new information about some factors that modulate the microbial ecology and the mechanisms involved in the adaptation of bifid bacteria to the conditions of our gut.” In the study, led by Marco Ventura in collaboration with Douse van Sincere (University of Parma and Cork, respectively) have participated universities of Aberdeen (United Kingdom), California (USA), Siena and Verona (Italy) and Aix- Marseille (France), in addition to the Dairy Institute of Asturias, CSIC.
