Scientists find new bacterium that lives of caffeine.

Scientists of the University of Iwoa, in the United States, had discovered a new a bacterium that lives of caffeine in a type of flower that had in the campus. The putida Pseudomonas digests the existing caffeine in the ground and some species of plants, as the coffee, grass-kills and the cacao.

Previous research already showed some bacteria that if they fed of the present caffeine in vegetables and served as natural pesticides. But not if wise person as they digested the composition. Now the researchers had discovered that putida the Pseudomonas bacterium uses the N-demethylase enzyme to break the caffeine in dioxide of carbon and ammonia, thus to use to advantage it.

The team isolated the genes of the putida P. that they had distrusted to be the responsible ones for producing the caffeine enzyme digestora. Later they had inserted the genes in a different bacterium and capsize that it also started to digest the composition.

The discovery will be able to help in the treatment of some problems of health. This because the by-products generated for the caffeine in addition are the base for some used remedies to treat asthma, to improve the sanguineous flow and to fight the cardiac arrhythmia. As these products they are difficult to be produced in laboratory, the enzyme of the bacterium could be a simpler form to manufacture them.

The 9 myths of the feeding.


He is false to say that the bread fattening and that who is to make diet does not have to eat it. This food supplies about 250 kcal/100 g and, as any food, must be eaten with moderation. The great problem is not the bread by itself, but yes what we join to it. To have an idea… 10g of butter kcal has 90 approximately. Also it is not truth that the integral bread gets fat less than the white bread, therefore supplies the same calories significantly. But the integral bread (or it mixes, rye, 7 cereals) is nutricionalmente richer of what the white bread, supplying vitamins, minerals and alimentary fiber that, as related, are nutrient basic in our feeding.

It is a common error to say that she is necessary to ingest much meat, of preference a beefburger, to have energy. White Teresa says that “it is necessary to ingest meat, but is not through an ingestion in surplus that I go to have more available energy. This ingestion in surplus alone will serve to store a great amount of saturated fat”. Already Francisco Varatojo remembers that the macrobióticos have vitality without eating meat and that they go to search proteins and other nutrients to the leguminosas as the beans and the grain, for example.

“It does not have nothing that confirms that she is necessary to drink milk to have strong bones”, it underlines Francisco Varatojo. The macrobiótico remembers that it is in the occidental countries, where if consumes lacticínios more, that more ósseas fractures and cases of osteoporose are registam and that the orientals have a more resistant skeleton and consume little milky products. One of the explanations must it the fact of the lacticínios be had much protein that finishes for eliminating calcium in time that holding. To strengthen vitamins, and D also the red food ingestion as vegetal, hortícolas, fruits or oranges are advised to a solar exposition of 15 minutes daily and green leaf, fish fat people and eggs.

Blessed Alexandra demystifies this idea. Although “theoretically to have little calories of what the products not “light”, does not want to say that if can eat the amount that if it desires without getting fat”. E calls the attention for the necessity to be intent to the labels of foods: “Many times, the manufacturers remove the fat, but they substitute it for other ingredients that can present calories and therefore the energy value of the end item can very not be inferior to the one of the conventional product.”

A small banana has the same calories that an apple or an orange, does not have fruit that gets fat more than what to another one, is only necessary to have in attention the amounts. In the fruit, transformed into the highest point, vitamin C is degraded and the natural sugars (frutose) are consumed of more intent form and provoke more dental carieses.

It is said that if it does not have to drink water to the meals or during the physical efforts, but is a myth. Without the nutrient water, a good hidratação does not exist and nothing it functions. However, as it relates Francisco Varatojo, also it does not make sensible none to say that to be healthful we need to drink three liters of water per day. E the water of the tap more is balanced in essential minerals for the health that the bottled mineral.

He is false to say that the fish does not feed. According to Blessed Alexandra, “the fish is more easily digested of what the meat and a protein source of raised quality”, having a reduced text of fat more. Moreover, it adds: “The fats of the fish are more healthful. The fish fat person, as the sardine, the salmon, the herring, presents ómega 3, acid fat people who seem to present many benefits for the health.” One of the forms to delay the digestion of the fish, is to more follow the meal with other foods of delayed digestion, nominated vegetal folhosos, as borecoles and leguminosas as peas, beans, garbanzo bean, lentils…

The oil, although to be a healthful fat, fattening in such a way how much the other fats. Each 100 oil g supplies 900 to us kcal. Therefore the oil must be used with account, weight and measure. But that if it prefers oil other saturated fats as oils. It is that the oil has other nutricionais advantages, since is rich in antirust substances, diminishes the cholesterol levels and contributes for the reduction of the risk of illness cardiovascular and determined types of cancer.

“Of the point of view of the nutrition, it does not have good foods, nor bad foods”, underlines Alexandra Blessed. Any food can be part of a balanced feeding and therefore the advice to have a healthful feeding is to vary most possible. Exactly the rich foods in fats or sugar, that are pointed as little healthful, do not have to be banished of the feeding of a healthful person, but to be ingested with account, weight and measure.

Brazil studies to include insects in the diet of the people

Already it thought to go to the supermarket and, instead of 1 kg of bovine meat, to buy 500 grasshopper g, cricket or larva of ant? Therefore this reality can be part of the life of all the Brazilians very soon!
Owner of a company that creates and commercializes insects, the mining entrepreneur Otávio Luiz You can Gonçalves asked for to the Ministry of Agriculture, Cattle and Supplying that its business recognized as a “producing establishment of insects for human consumption” and finished fomenting, in the government, the debate on the legalization of the entomofagia - that is, the practical one to eat insects - in Brazil.
The Ministry of Agriculture not yet answered to the order of Gonçalves, but it asked for bibliographical indication to the entrepreneur, alleging that if it deals with controversial subject, but that it will be argued, for representing real chance to fight the global heating in Brazil and the world.
This because, in accordance with research of the University of Wageningen, in Holland, the creation of insects emits an amount of gases of the effect very lesser greenhouse of what the cattle one. In the case of grasshoppers, for example, the methane emission arrives to be 10 times lesser and of nitrous oxide, 300 times. Moreover, the production of insects also would help in the preservation of the forests, that they would not need to be destroyed for the advance of the pastures.
Data of the FAO - Organization of United Nations for Agriculture and the Feeding - that also walks arguing the possibility to include insects in the diet human being - still they show that about 80% of the countries they possess insects in its cardápio and 23 of these nations are in the American continent. It will be that the Ministry of Agriculture will legalize the entomofagia and Brazil will be the next one to enter, officially, for this list?
In case that the proposal of Gonçalves is accepted, for the entomofagia, really, to make the difference in the combat to the global heating, the population would have that to change to the bovine meat and suína for the one of insect. You would change?

Top 10 foods that detonate its health

What it does not kill, fattening, said our mothers. Or we ourselves, when we want to eat salgadinho that it fell in the soil. The problem is that some things not only get fat (and very), as well as can kill to the few.

But it does not need to be despaired. This that does not want to say that we cannot more eat that portion of potato fries or that one docinho in the dessert. “Nothing it is forbidden, but these foods must be consumed with lesser frequency. A reasonable measure is to include an one of them in the cardápio time per week. But only one of them. To eat dog-hot with potato fries, for example, never”, it explains Flavia Moral, coordinator of the department of nutrition of the net of natural products Green World. The tip of it is to look at the label of the product to check its ingredients. E is intent: the first item of the list of ingredients, generally, is what it is present in bigger amount in the food. Therefore, if sugar or fat will be in the top of the list in the packing, either better to perhaps look a more healthful option.

With the aid of nutritionists, we list the 10 types of more harmful foods to the health. Care with them!

10 - Sugar

“The sugar, in special the fine one, is 100% calorie, without nutricional value”, affirms the Thais nutritionist. Yes, it becomes the life and foods more candies and all. But, when consumed in excess, he is stored in our body under the form of triglicérides, increasing the risk of the development of cardiovascular illnesses. Moreover, for being caloric, he can lead to the obesidade and, with it, increase the risk of diabetes, hipertensão and dislipidemias. According to nutritionists, as much sacarose (table sugar) how much the sugars of industrial use are related to me the quality of the health. Then, already he saw: nothing to sweeten excessively cafezinho.

9 - Margarina

According to one it searches dutch, some margarinas provoke as much males for the arteries how much the fat of animal origin, known as saturated. Aa margarinas is of vegetal origin, that is, its insaturadas fats do not costumam if to deposit in the sanguineous vases. But the dutches had observed that a component of definitive margarinas, the acid elaídico, even so if does not accumulate in the vases, provoke the reduction of the beneficial lipídios of high density. These receive the nickname from good cholesterol, because they clean the organism of the fat of low density, the bad cholesterol, that obstructs the circulation of the blood. As of the one not to know if definitive mark it contains or not it substance, sends regards that for precaution, if it prevents any type of fat.

8 - Barbecue

Ok, to fry is bad. But it takes care when to decide to also make a barbecue. In this in case that, the problem is in the preparation process, and not with the food: according to Thais nutritionist, the smoke of the coal liberates aromatical tar and policíclicos hydro-carbons, substances with high cancerígeno potential.

7 - Frituras

Exactly that you use vegetal oil of good quality to fry its potatoes or beefburger, to eat foods fritos makes badly. The fritura makes with that chemical alterations in the used oil occur, leaving of being a source of insaturada fat (in the case of vegetal oils), basic for our health, and giving place to the saturated fat, that in excess can cause diverse illnesses. This process can also promote the formation of the fat trans, that directly it is related to the increase of cardiovascular illnesses and the worsening of the picture of health in a general way. Moreover, the extreme heat ruins the chemical structure of the fat molecule, producing a substance potentially cancerígena call acroleína.

6 - Cooling

“Beyond possessing many artificial substances in its composition, the cooling one contains almost null nutricional value”, affirms Thais. The variations glue, in special, have a great amount of fosfatos, that in excess provoke the release of calcium and the consequent weakness of the bones, facilitating the incidence of illnesses as osteoporose. “Beyond being rich in sugar, the drink has the capacity to deceive the related organic systems to the control of the ingested calories, presenting close relation with the extreme profit of weight and the obesidade”, adds Rafael Clearly. E, unless you are diabetic, does not advance to try diet - they are still worse! “Cooling they contain many chemical substances, but at least they are made with sugar, that is something that the body recognizes and can digest. Already cooling diet, beyond all these substances, still contain aspartame as sweetener. Its metabolization generates methanol, toxic substance for the neurons that, in excess, neural degeneration provokes and is related the illnesses as badly of Alzheimer”, explains Flavia Moral.

5 - Salgadinhos

It is this same. Another dangerous delight that we adore to consume at ócio moments. The salgadinhos also are sources of monossódico glutamato, that sódico salt that creates a encorpado flavor to the product. But you already saw back in item 3 of what this composition is capable.

4 - Stuffed biscuit

These small temptations with chocolate filling, strawberry or what it will be are non-separable of idle afternoons in the front of the television attending some film on one galera of the racket preparing high confusions. “Loaded with sugars, these small dainties possess frightful energy density”, say the nutritionist Clearly Rafael Moreira, Researcher of the Department of Nutrition of the College of Public Health of the USP. Beyond the sugar excess, the stuffed biscuits still contain much saturated fat, what it favors the increase of the LDL (the “bad cholesterol”) and the reduction of the HDL, considered the “good cholesterol”. The disequilibrium in the cholesterol taxes is factor of risk for the sprouting of serious cardiovascular illnesses. E, to complete, the used additives to give color to these big cookies also are harmful to the health and are associates to the hiperatividade and deficit of attention.

3 - Industrialized broths and temperos

It decided to cook? Good for you. But another tip goes here: it makes its proper one I temper and I forget the industrialized ones. They possess high sodium texts and monossódico glutamato. Sodium, if consumed beyond the recommended daily limits, can lead to the development of the hipertensão or to get worse the problem if it already exists. The problem of the glutamato is still worse: studies have shown that to our it uses it organism as a transmitter of nervous impulses in the brain and its consumption has been associated with learning difficulties, Badly of Alzheimer, Parkinson and cancer.

2 - Inlaid (sausage, linguiça, mortadela, ham, salame)

Ok, you is not adept of the congealed ones, but lanchinho of mortadela adores one. Or a dog-hot one. We feel to inform, but you are not in a better situation, not. “These foods to the meat base, known as inlaid works, had been invented to facilitate the preparations and to increase the stated period of validity of the food. The problem is that they possess greater text of fat saturated in relation to the natural meat”, explains Thais Souza. This type of fat, found mainly in products of animal origin, brings risks to the health when ingested in excess, therefore it stimulates the increase of the cholesterol levels and the risk of development of cardiovascular illnesses. The inlaid works also contain sodium excess - what it can provoke high pressure - and corantes - that they can cause allergies and problems in the stomach. Finally, still it has there many conservantes, as the nitrito and nitrate. Into our organism, them they are converted into potentially cancerígenas substances.

1 - Congealed ready meals

You arrive in hunger house dying and are tired excessively to cook something. Then, he looks at for the microwaves, one remembers lasanha frozen that he has in bendiz freezer and this pretty technology that facilitates its life. But it is good for not empolgar itself in such a way. This type of half-soon food is rich in saturated fat, that makes to go up the levels of the bad cholesterol and increases the risk to develop cardiovascular illnesses. “Such meals also are rich in sodium that, in excess, can cause increase of the arterial pressure”, it affirms the Thais nutritionist Souza. It decided to change for the pizza? It does not advance. The risk is, basically, the same.
