What is a food additive?

Food additives are substances added to food in a specific technical purpose. They are classified according to the function they perform when added to foods: stabilizers, thickeners, gelling agents, anti-caking agents, coating agents, packaging gases and propellants. Only a substance not normally consumed as a food in itself and not used as a characteristic ingredient of food meets the definition of additive. In the European Union (EU), three directives specify the list of additives permitted for use (excluding any other), the list of foods to which these additives can be added and the maximum quantities permitted. When a food additive is permitted in Europe, it has a number E (E for Europe), which is also a way both simple and convenient to label permitted additives in the various languages of the European Union.

Stabilizers

Many foods contain emulsions of oil and water. The emulsions were prepared using substances called emulsifiers that allow water and oil mix. The stabilizers are used in the manufacture of products such as mayonnaise, salad dressings and ice creams to prevent separation of ingredients and preserve their texture and physical properties. The most common stabilizers are locust bean gum and alginate.

Thickeners

Thickeners are added to foods to increase fluid viscosity, they usually consist of carbohydrates such as hydroxypropylmethylcellulose. Thickeners based on carbohydrates allow heated liquid to thicken as a result of absorption of water by starch granules (which are composed carbohydrates) and therefore, their swelling. This process involves the trapping of water molecules in the starch granules and thickening fluid. The thickeners are added to a wide range of foods and sauces.

Gelling

Gelling agents are used to thicken and stabilize the liquid food, and thus give them more texture. Although their function is very similar to that of thickeners, such agents, as their name suggests, form a gel. Gelling agents are usually proteins or carbohydrates, which when dissolved in liquid foods form a three dimensional crosslinked network. The result is a unique aspect of food consisting of, but which is mainly composed of liquid such as jellies, jams and confectionery. The most common gelling agents are pectin and carrageenan.

Anti-caking

Food powder or pellets readily absorb moisture, causing the clumping of particles and lumps. These clots make it difficult to use food powder or granules because they can not be weighed, toast or mixed uniformly. The anti-caking coat food particles and absorb excess moisture. By preventing moisture from reaching the surface of foods, these agents help prevent clotting and to maintain the fluidity of the product. An anti-caking agent most commonly used is calcium silicate, which is used to prevent clumping of table salt or baking powder.

Coating agents

The coating agents give an appearance of both bright and smooth foods and provide a protective coating. They are used for confectionery, fruit and baked goods. The coating agents are the most common beeswax, carnauba wax and fatty acids.

Gas packaging

The packaging gases are used to change the atmosphere in which food is packaged to control ripening, prevent chemical changes and avoid harm. For this, we use a technique known as the modified atmosphere packaging (CAM) which involves replacing the air in contact with food by a mixture of pure gases such as oxygen, carbon dioxide and nitrogen. According to the feed and the desired effect, different preparations of gas are “powered” in the package. Thus, a mixture of carbon dioxide (30-60%) and nitrogen (40-70%) can inhibit the growth of many micro-organisms and halt microbial spoilage of meat and fish, while a mixture of carbon dioxide (20-30%) and oxygen (70-80%) can prevent the red meat discoloring.

Propellants

The pressurized aerosol containers are used to present food fluids as liquid, foam or droplets (or spray). The use of propellants provides the necessary pressure to expel the liquid from the aerosol container. The propellants most frequently used are nitrogen, nitrous oxide and carbon dioxide. Nitrous oxide and carbon dioxide are usually used for products in the form of droplets or foam like whipped cream, cheese and mustard. This is because these agents are dissolved in the liquid food and expand upon the expulsion of the container, resulting in the formation of droplets or foam. Nitrogen does not have the same properties; it is rather used for liquid foods such as oils and syrups.

A panic attack is an anxiety disorder severe, where mental and physical symptoms seem to feed each other: heart palpitations, difficulty breathing, sweating, dizziness, and combine with a feeling of loss of self control, printing to be dying. If the biological and psychological origins of these crises are often difficult to unravel, it has been shown to be induced, both in humans and in animals by sodium lactate or inhalation of CO2. Drugs are available to the curb, but they are not without disadvantages (risk of dependency). A new study illustrates the role of this hormone in anxiety disorders, may open new therapeutic avenues.

A Swedish-US team has indeed found that certain molecules that inhibit the orexin (also called “hypocretin) could reduce panic behavior observed in rats selected to present these anxiety disorders. Philip Johnson (Indiana University) and colleagues also showed that activation of neurons that synthesize orexin is necessary for the onset of panic in these rats. Finally, they found that patients prone to anxiety panic showed concentrations of orexin in the cerebrospinal fluid higher than in a control group.

The orexin has been widely studied for its role in the awakening and its disorders: some dogs with narcolepsy have mutations of orexin receptors, while humans, the molecule is stimulating these receptors is lacking. Recently, a team led by Jian-Sheng Lin (Inserm Unit 628, Université Claude Bernard, Lyon) showed that mice manipulated to express not the orexin directly entered REM sleep and catalepsy. Regarding panic “Correlation is not causation”, Said Mr. Lin, who wonders whether orexin antagonists used by his colleagues simply do not cause drowsiness in animals.

“Instead, the treated rats and show more social interactions and increased exploratory behavior, which goes against the assumption of sedation”, Write Philip Johnson and colleagues. Antoine Pelissolo (Hospital de la Pitie-Salpetriere) said their study “preliminary, but serious, in an area where the tracks are quite limited therapeutic”.

As part of its weekly review, the French Agency for the Safety of Health Products (AFSSAPS) announced Friday, November 13th only four adverse events “serious”, including Guillain-Barre have been identified among professionals Health vaccinated against influenza A. Investigations are underway to determine whether these effects are either unrelated to the vaccine. Moreover, a young woman of 27 years, carrying the influenza virus A and without medical history, died Tuesday of heart failure after presenting respiratory

What side effects have been reported among persons vaccinated?
Of about 100,000 health professionals vaccinated between October 21 and November 10, four adverse events “serious” were identified by Afssaps two neurological disorders, allergic reactions and respiratory disorders. It was first reported a possible case of Guillain-Barre to moderate, occurred in a woman 37 years after treatment, has recovered well and was able to return home.

The second case is angioedema, an allergic reaction that can, in some cases, cause a serious risk of suffocation. In this case, it occurred within minutes following vaccination in a 26 year old woman whose condition after treatment, improved “without any sequelae. The third case of neurological disorders (numbness of the upper limbs) seen in a man of 34 years, too, is better. Finally, a 30 year old woman with a history of allergy presented a respiratory (bronchial spasms, shortness of breath). “His condition is improving under appropriate treatment,” says Afssaps.

What is Guillain-Barre?
It is an attack of nerves that results in rapid paralysis, usually starting at the legs, then back up the body. In 85% cases, the patient recovery is complete, but 5% of people die and 10% are affected negatively. In France, there are each year between 1 700 and 1 800 cases of Guillain-Barre. The risk of developing this condition after a flu shot is one or two cases per million persons vaccinated. According to experts, in two thirds of cases, this syndrome is triggered after a viral or bacterial infection. The infectious disease stress is therefore more likely to have Guillain-Barre after the flu after vaccination.

These side effects are they related to the vaccine?
In the case of angioedema, it is quite possible. “It is an uncommon side effect, but can occur after vaccination,” says Carmen Kreft-Jais, head of pharmacovigilance Afssaps. For three other cases, she said that investigations are underway to try to decide on possible vaccine accountability. “It is quite possible that there is no link between vaccination and the onset of the cases of Guillain-Barre. But we can never be certain, “says Professor Odile Launay, head of clinical investigation center of vaccinology Cochin-Pasteur in Paris.

Last Monday, Didier Houssin, director general of health, reminding that every day, normally between three and five people were hospitalized in France for Guillain-Barre. “Inevitably, there will be other cases in the coming weeks. Among these patients, some may have been vaccinated in previous weeks. And it will be very difficult to know whether the syndrome is linked to the vaccine or has another origin, says an expert. For Afssaps, these side effects does “not undermine the risk-benefit balance” of the vaccine.

To fight against teenage pregnancy, the president of the Poitou-Charentes wants to help high school students to finance their contraception and regret that the Ministry has not yet approved.

Why is the area she decided to fund contraception to young girls?
In Poitou-Charentes, 455 underage girls were pregnant in 2007 and only 30 to 40% of these pregnancies were carried to term. Furthermore, if the regional rate of voluntary termination of pregnancy (abortion) is below the national average among women aged 15 to 49 years (11.1 per 1 000 women against 14.5 on the whole in France 2006), it is higher among girls 15 to 17 years.

The president of the Poitou-Charentes, Segolene Royal, who is responsible for access to emergency contraception in the schools, wanted to go further in preventing teenage pregnancy. “We conducted an in-depth work with associations, parents, teachers, school nurses and physicians to develop an intelligent tool,” says she Cross.

Specifically, the “check contraception,” an amount of 82 € must allow minor girls to finance a medical consultation, blood tests if needed and the purchase of contraceptives over a period of six months .

This should be implemented in schools by school nurses and training centers for apprentices or rural family homes and through associations. With a budget of 300 000 € by Regional Council, the scheme provides co-funding by the Academy of Poitiers for the mobilization and training of school nurses.

This arrangement aims to facilitate access to contraception for young girls in confidence. “If the prescribing and dispensing of contraceptives are no longer subject to parental authority since 2001, only planning centers and family education permit issued anonymously and free, while consultations with practitioners involve an advance of funding and support by the parents ’social security’, says one of the region, noting that demand for “morning after pill” is steadily increasing in schools. About 1 000 requests from school nurses have been recorded on three school years.

When this device will he put in place?
Voted in March by the standing committee of the region for entry into force in the autumn 2009, the check contraception has not yet been implemented in the schools of the Academy of Poitiers.

According to Segolene Royal, the Ministry of Education refuses to endorse the implementation of this device. “It is outrageous that the Ministry is blocking this issue,” says the president of the regional council, which claims to have conducted a “substantive work with multiple partners in education for many target things.”

Without agreement with the rectory, the Region said that checks and contraception information posters will still be sent to schools next week, “including vocational schools that are particularly affected by the phenomenon.

The education minister, Luc Chatel, expressed its strong opposition: “We’re dealing with juvenile students. Parental authority is something that matters. The National Education does not substitute for family planning, only allowed to prescribe contraceptives to a minor child. ”

“In each school, is a board of health education and citizenship, with our personal health of Education, provides advice to students regarding sexuality,” continued the Minister.

Francis Levi, cancer (1), just to show that we can improve chemotherapy

Cross. You have just published an article (2) showing interest in patients with cancer receiving treatment, taking into account the biological clock of each individual. What is this therapy?
Francis Levi: We have shown that taking into account the biological clock of patients in the administration of drugs can reduce their toxicity on healthy cells. This is called chronotherapy. It aims to determine the ideal time to administer a drug during chemotherapy, taking into account the internal biological rhythms of the body: rectal temperature, rate of secretion of hormones, the rate of activity of detoxification enzymes liver…

What is the initial idea?
Today, most cancers are treated with chemotherapy alone or in combination with surgery or radiotherapy. Side effects of the chemotherapy are many and can sometimes lead to discontinuation of treatment due to a risk-benefit balance against. The chronotherapy is a solution to minimize these possible effects, or improve the effectiveness of treatment.

Has shown your last job?
Within the European project tempo, we tested the chronotoxicite two molecules, irinotecan, used for the treatment of colorectal cancer, and Seliciclib, under development. In humans, the adverse effects of irinotecan are manifested by severe diarrhea in 30% of patients, a decrease in white blood cells in almost half of cases and a state of extreme tiredness. As for Seliciclib, it can also cause severe fatigue and metabolic disorders. In mice, we administered these drugs at different periods of sleep-wake rhythm that lasts about twenty-four hours. Results: The harmfulness of these molecules varies at least from one to three depending on time of administration. Thus, it is likely that, in humans, irinotecan should be administered at about 5 o’clock in the morning and Seliciclib to 2 am. We have also shown that chronotoxicite depends on sex and genetic makeup of animals.

What this will change for patients?
Based on these results, we will adapt the treatment of patients with programmable pumps (chronopompes). Currently, a dozen cancer services in Europe, the chronopompe is set to profile chronobiological means. Now it will be based on chronobiological profile of each patient. This will enable personalized medicine and ambulatory treatment better tolerated psychologically. Furthermore, we are developing a thermometer implanted that will provide physicians the internal biological rhythm of each patient. This will fit even better treatment. Seven teams are European and testing from 2010 therapeutic methods based on these rhythms.

At least thirty minutes of daily exercise are necessary to avoid the risk of stroke or cardiovascular brain. Do together with healthy diet consumption of snuff and not for emotional and mental balance. Physical activity helps strengthen the heart muscle and maintain proper operation.

Changing lifestyle habits can reduce the risk of stroke. It is best not to wait for more than 30 years who want to prevent diseases that may have started growing in the body. Then after that age is starting to become evident excesses of youth.

They are said to people over 50 who are more prone to heart attack today but certainly people are dying younger because of this evil. Lead a sedentary lifestyle because they do not practice any sport, they do not exercise; they eat poorly, consuming liquor and snuff. In recent years it has been said that years die about 15 million people a myocardial infarction.

Walking, an activity less effort and requires only discipline, willingness and little time. With only 30 or 60 minutes of daily walking you are oxygenating your body, strengthen their heart and breathing and regulating metabolism.

Jogging or running, this type of activity or exercise requires more capacity but goes along with walking because after having a routine of constant path will be much easier and fun start to run. Running are encouraged a lot more heart and heartbeat.

Walk up and down stairs. Sometimes humans use escalator or the elevator, go in your car or motorcycle right to chair or bed and devotes little or no physical activity. Walking up stairs, lower, running and walking are simple but safe ways to reduce risk for heart attack. Establish a daily routine is paramount and can do so at their place of residence or work if necessary.

For those who prefer the cardio fitness will be the greatest help to prevent heart attack risk in this type of activity is much movement, coordination, burn calories and stimulation of cardiac and respiratory activity.

Do not exceed capacity

Excessive exercise and physical activity can also lead to a heart attack. So it is vital to be taking heart rate, blood pressure checked and be careful not to exceed one’s limits. There are people who have suffered heart attacks during sports and even died.

Sport is a source of health but must be properly controlled and if possible addressed. For walking, running up and down stairs is not up to you to monitor the limit switch and guard his heart.

The tea especially green and red varieties is a great ally to lose weight. They are beneficial owners of properties and qualities beneficial to the organism. On the one hand detoxify and cleanse the body, promoting diuresis, also stimulate the secretion of digestive glands and facilitate the digestion of fatty foods. In fact many diet pills include them within their basic ingredients.

Green tea for its part is a powerful antioxidant that prevents oxidation of cholesterol.

It has two active ingredients: polyfenoles and tannins, among which stands out caffeine. These substances stimulate the oxidation of fat and slow the absorption of certain nutrients like fats and sugars. For its part, the caffeine helps break down fat in the body into simple elements, which can be easily burned. The action of these substances increases the calorie expenditure through thermogenesis.

Green tea is also hypolipidemic, i.e. has the ability to reduce levels of LDL-cholesterol and plasma triglycerides while increasing HDL-cholesterol, good cholesterol.

Red tea, also known as the “tea of the emperors” or Pu-Erh, is considered by traditional Chinese medicine as “health drink”. It has also been the subject of numerous studies in that country, with results really motivating.

One example is the study by the Institute of Chinese Medicine, Kunming, which showed that people who are slightly overweight, can lose three kilos if you eat three or four cups of red tea a day. And considerably overweight people can lose up to nine kilos and five cups a day. Other tests show that red tea is low in tannic acid, allowing its use to people with weak stomach.

Another of the great benefits of red tea is:
* Has diuretic properties. Favors the regulation of intestinal transit.
* Enables the production of enzymes that accelerate cleansing the liver metabolism and help remove toxins and waste from the body.
* Turns digestion, improve intestinal laziness
* Stimulates the kidney to the elimination of liquids.
* Increases and accelerates fat metabolism and the secretion of digestive glands.
* Reduce fat levels, cholesterol and uric acid.
* This is an excellent liver detoxifier, which helps eliminate toxins and waste from the body.
* Stimulates the gallbladder, emulsifying fats better.
* It is an excellent antioxidant, therefore helps cell renewal.
The red tea can perfectly accompany any diet to lose weight, take 4 cups of red tea per day, and increase the weight loss and detoxification.

It should be noted that although the benefits are many, it is always best to consult a physician before taking any product to ensure fat burning, no matter whether they are herbal or natural. Always anticipate the risks and health care.

You’d thought he’d left those ugly pimples and acne outbreaks at the time of adolescence. Now an adult, after all, and that is why we feel immune to such unpleasant experiences, such as acne outbreaks.

Although a face full of pimples could make it run for medicines to cure this condition, should stay quiet as it is estimated that 50% of adult women experience problems with acne at some point in their lives. On the other hand, might console them by relying on the fact that experience frequent outbreaks of acne during pregnancy not only be perfectly normal, but will be something all too common.

Although there are some lucky women whose problems with acne disappear during pregnancy, most of them are not so lucky. All women who have to deal with acne caused by pregnancy probably will think the worst moment in regard to the appearance of grains is in the first quarter. However, as your pregnancy progresses, your estrogen levels that will increase and your acne will certainly be greatly reduced or could eventually disappear altogether. Although nobody can predict who will experience outbreaks of acne during pregnancy, women who have previously had problems with acne or are more prone to outbreaks just after their periods would have greater difficulties with acne during their pregnancies.

But why she has suddenly decided to make a nostalgic journey back in time to reach their teenage years? Well, like most symptoms of pregnancy, their new grains can be attributed to increase their hormones. As hormone levels increase, the production of oil from your pores will increase, causing your skin to become oily. In some pregnancies, this new oil will cause it to radiate that “glow of pregnancy itself” to have so many women. But for others, oily skins will only be a recipe for disaster causes his face. The worst thing is that you might get to recoating that these grains are not only limited to appear on his face. Along with facial acne, you may also experience body acne.

While many women may think that this is a trivial issue to be taken seriously, you’re going to have a baby after all. The reality is that the grains might actually have a negative impact on self-esteem. As an adult, you will not expect to have to worry about your skin again. And although it might be able to pay for products for skin care market more expensive, will certainly have better things to spend their money at this point in his life. If it were also experiencing outbreaks of acne on his back or chest, then your ability to see yourself as the queen of pregnant women could be completely gone. Read the rest of this entry

How to Clear Acne Scars?

This article is focusing on natural ways to clear the scars acne. Home treatments are one of the best methods possible to erase scars acne.

Clear Acne Scars 1: Lemons

If scars Acne is dark, you can use lemon juice brand to disappear. First, clean the marks of acne with water. Dab a teaspoon of lemon juice into a cotton ball and smooth over the scars acne. Let stand 10 minutes, then rinse. Be careful with the lemon juice because it can make your skin photosensitive. So be sure to use sunscreen on any area you treat with lemon juice before going out in the sun.

Clear acne scar 2: baking soda

Another home treatment to remove the acne scar is using baking soda. Exfoliate your skin with soda. You can give yourself a mini microdermabrasion treatment by mixing one teaspoon of baking soda with two teaspoons of filtered water. Then gently rub the mixture on your acne scar for sixty seconds then rinse.

Clear Acne Scars 3: Olives

After exfoliating your skin with baking soda, massage with olive oil on your face. Acne fear can cause the skin to lose its elasticity and flexibility. The moisturizing nutrients in the olive oil will penetrate into the skin to deeply moisturize the skin and reduce skin texture.

The price range of Fifty-One Trio kits is $22.76 to $174.99.These kits can be seen on display in most of the fuel stations these days. We received this E-cigarette for an unbiased and honest review. The fist thing we observed s we got the kit were its contents.
• Two pieces of Li-Ion rechargeable batteries
• One charger with cable to charge the batteries
• One membership card of Club 51
• One atomizer with 6 cartridges
• One user manual

There are many pluses with Fifty-One Trio E-cigarettes. The first being its attractive and professional packing. 2nd pro obviously is the reputation of the company making it. The company is known for its efficient products and its great after sale service that includes fast shipping and something that consumers only dream of, a life time warranty to replace a faulty product.

To be frank, I was not impressed with the amount of vapors I got with a first few puffs as the atomizer supplied takes some time to get primed. After a few puffs you will get as much smoke as you get from your regular cigarettes. Fifty-One Trio is far ahead of Blu and Luci in this aspect though it is still behind Fifty-One Duo in the amount of vapors produced.

Fifty-One Trio does not hit the throat as much which is a relief for many smokers. Those who are just casual smokers, do not like harsh cigarettes in any case, but those who smoke heavily (and I am certainly one of those) would find this E-cigarette is a little short on this aspect.

Fifty-One Trio tries hard to mimic the taste of a real cigarette, but does not feel quite like a real one. This is because of the difference in ingredients and also because an E-cigarette can never really taste like a real one because there is no fire involved. Good thing about this E-cigarette is the seal of approval from the doctors as they found no carcinogens in this cigarette. What this means is that even if you are not getting the real feel, you are being spared from the harmful effects of 4000+ carcinogens.

If you go out of stock, you can purchase refills from anywhere in the market. However, you have the option of pre-filled cartridges that are available in menthol and tobacco flavors. The reason for selling only 2 flavors is to discourage kids from taking up these-cigarettes. All in all, a great substitute for real cigarettes.
