Constipation is one of the most common gastroenterological disorders, common among Western populations. We may suffer from both adults and children of both sexes (although it is more among women) and is usually characterized by greater difficulty in evacuating fecal waste and reduced frequency of bowel movements. We have all suffered or suffer from constipation at some point in our lives, but those who suffer this type of intestinal disorder most often know what is uncomfortable and sometimes painful as it may be this situation. Vitamins are not chemicals synthesized by the body, present in small amounts in foods, which are essential for life, health, and daily physical activity.
The vitamins do not produce energy, therefore no calories. These act as a catalyst in biochemical reactions leading to the release of energy. In other words, the function of vitamins is to facilitate the transformation that followed the substrates through metabolic pathways.
Division:
Vitamins are divided into 2 groups, which are:
Soluble vitamins
This group included vitamins A, D, E and K. They are soluble in fatty substances, are little altered, and the body can store them easily. Since the body can store them as a reserve, would be based on its lack bad eating habits.
Vitamin A
This vitamin is involved in vision, growth, development of bones in the maintenance of epithelial tissue (skin, hair, nails, mucous membranes of the eyes and respiratory system, etc.).. immune processes and to avoid infections.
Vitamin A or Retinol is found in animal products and carotenoids infruits and vegetables listed below from highest to lowest amount of this nutrient: liver, carrots, spinach, peaches, milk, broccoli, egg, cheese, pear, butter, orange, apple, etc.. my best song, with two of the greatest, Michael Jackson and which I watch every day on YouTube Here it is worth mentioning that in terms of bioavailability is better absorption and utilization of this nutrient is the best of foods rich in retinol than the carotenes.
Vitamin D
This vitamin is enough energy for the intestinal absorption of nutrients like calcium and protein. Its deficiency is also aggravated because causing a calcium deficiency, as its absorption is poor, leading to rickets in children, a disease that causes malformation and demineralization of bone.

Vitamin E
This vitamin is involved primary function as an antioxidant, is something like a shield of the membranes of cells that do not age or deteriorate by free radicals that contain oxygen and can be toxic and carcinogenic. Participation of vitamin E as an antioxidant is of paramount importance in preventing diseases such as cardiac ischemia, toxemia during pregnancy, thrombophlebitis, fibrosis of the breast and trauma, where there is a significant destruction of cells.
Vitamin K
Vitamin K is liposoluble, and participates in various metabolic reactions, such as coenzyme, and also forms part of an important protein called prothrombin protein that is involved in blood clotting.
Vitamin K is found in many vegetables such as broccoli, pumpkins, lettuce, but is also found in smaller amounts in other vegetables, the fruit in cereals, dairy products, eggs and meat . Another source of vitamin K, which occurs within the organism in the gut bacterial flora are producing a vitamin K which is called menadione.
Water-soluble vitamins
Consists of the B vitamins, as well as the C. Within this group of vitamins, reserves in the body not important, so the diet must provide and meet the daily needs vitamins. This is just to be at its hydrosoluble almacentamiento is minimal. The need for water-soluble vitamins should always take into account the level of physical activity of the individual, since the exercise activates numerous metabolic reactions which vitamins are coenzymes. This will lead to a situation in which the physical activity, there are risks of gaps and therefore appear supplements.
B Vitamins
They are fragile substances, soluble in water, several of which are especially important for metabolizing carbohydrates.
The water-soluble B factor, initially considered as a single substance, proved to contain several active ingredients vitamin.
The individual compounds are designated with the letter B and a numerical subscript. The current trend is to use the names of each substance.
The so-called vitamin B complex includes the following compounds: thiamine (B1), riboflavin (B2), pantothenic acid (B3), nicotinic acid (B5), pyridoxine (B6), biotin (B7), folic acid and cobalamin (B12).
B 1
Thiamine or vitamin B 1, a colorless crystalline substance, acts as a catalyst in the metabolism of carbohydrates, enabling pyruvic acid metabolism and making carbohydrates release their energy.

Passive Tags Passive tags have no power. The signal comes from readers induces a small electric current sufficient to operate the CMOS integrated circuit of the tag, so you can generate and transmit a response. Most passive tags used Backscatter received on the carrier, ie, the antenna must be designed to obtain the energy necessary to operate at the same time to transmit the response Backscatter. This response can be any type of information, not just a code identifier. A tag may include nonvolatile memory, write (eg EEPROM). Passive tags typically have distances of practical use between 10 cm (ISO 14443) and reaching a few meters (EPC and ISO 18000-6), depending on the frequency of operation and the design and size of the antenna. For its conceptual simplicity, are obtainable through a process of printing the antennas. Since not require a power failure, the device can be very small, can be included on a sticker or inserted under the skin (low-frequency tags). In 2006, Hitachi developed a passive device called -Chip with a size of 0.15 to-0, 15 mm without antenna, thinner than a sheet of paper (7.5 m). is used SOI (Silicon-on-Insulator) to achieve this integration. This chip can transmit a unique identifier attached to the 128 bits in their manufacture, which can not be modified and gives authenticity to it. Has a maximum read range of 30 cm. Hitachi in February 2007 presented an even lower 0.05 to-0, 05 mm and thin enough to be able to be integrated into a sheet of paper. These chips have the storage capacity and can operate at distances up to a few hundred meters. Its main drawback is that the antenna must be at least 80 times larger than the chip.

Agriculture and forestry 2:10 PM Wholesale markets of Maracaibo, Barquisimeto, Valencia and Coche, Caracas, become part of a monitoring system. Then control the amount of goods coming into these centers, the volume of distribution and the amount that reaches the final consumer, so inform the Superintendent of Silos, storage and warehousing Agricolas (SADA), Carlos Osorio. After holding a reunion with members of the executive Wholesale Car Market, the center, which distributes 80 percent of the vegetables that are consumed in the country, said Osorio In the Canaries, despite the fact that until a few decades was mainly an agrarian society, at present the weight of agriculture is low, although some products are very famous. Agriculture canaria covers only one fifth of the nutritional needs of the region. Traditional rainfed crops have become, in practice, a part-time farming, for farmers with incomes in other sectors. The upland has virtually disappeared in favor of the irrigation (or other land uses). This allows self-supply and a small inside, but not sufficient for the needs of the region. Cereal has practically disappeared. Now in its soil is cultivated the vine, potatoes and fruit and vegetables. These crops are located in the middle and upper zones of Tenerife, Gran Canaria and La Palma, and almost all the arable land of the rest of the islands. One feature of the area of crop canary is a resource terracing of slopes, and we're in a very mountainous region. Windward slopes, between 500 and 1000 meters, the crops are in need of moisture through the sea of clouds. Downwind crops are less water needs. Traditionally there was a dry polycultural serving local needs: potatoes, cereals, grapes, fruits, legumes, vegetables, etc.. But today profitable crops are directed to the market and none of these products are significant. banana cultivation. The banana is...
