Food allergies - a very common disease that is manifested by increased sensitivity to certain foods when ordinary harmless-looking food leads to the development of an allergic reaction. Pro food allergy probably heard almost all people, but most of them do not consider it a dangerous disease, and in vain, as the allergy is not as harmless as it seems at first glance.A certain kind of food may contain a sufficiently large amount of allergens are proteins and usually much less carbohydrates and fats.With food allergies the immune defense produces significantly greater than the rate of antibodies, thereby making the body hyperreactivity, which puts quite a harmless protein on a par with the infectious agent.In case of no involvement in the immune system, it is not a food allergy, food intolerance and simple.It may seem strange, but true food allergy is found often in the order of 2% of the population, it is most often the cause is heredity.
Food allergies in children usually occurs in the first years of life, the most common allergen is egg white.Then, most of her children "outgrow."
food allergy in adults in 80% of cases, is a condition that the researchers called "pseudo-allergy food."This condition is very similar to symptoms of a true food allergy, while the real reason lies in the normal intolerance of certain foods.In addition, some people develop a food psychosomatic reactions, and they are therefore begin to consider some food allergen for themselves
Food allergy - Causes
Nowadays food allergy is much more common than a few decades ago.Many researchers attribute this to the use of pesticides, pollution, many chemicals to which people are facing and enjoyed throughout life.It is estimated that within a year a person is exposed to about three thousand of all kinds of chemicals, so it is not surprising that the number of allergic reactions increases with each passing year.Every day our immune system is exposed to received drinks and food of various chemicals and inhaled potentially toxic molecules.This never-ending battle significantly overload the liver, there has been increasing as a result of allergic reactions.
Food allergy to cereals, or to be more precise, an allergy to gluten, the most dangerous form of allergy and is caused by barley, oats, rye and wheat.Affected celiac people can not tolerate in any way these cereals.Sometimes food allergy gluten may directly threaten human life, due to the fact that such people gluten causes erosion of the inner walls of the digestive tract, thereby preventing the absorption of essential nutrients.
in some way from the concepts of food allergy and food intolerance there is some confusion and if their manifestation, they are similar to each other, the causes of them are quite different.Food allergies - this immediate reaction of the immune system to any stimulus, which manifests the production of antibodies against foreign agents, in her opinion.Food intolerance - a delayed reaction to a certain food, usually develops after a few days and is manifested in a variety of unrelated symptoms.Most of the symptoms to food intolerance are generally very difficult to tie, so they are often confused with symptoms of other diseases entirely.
most common food allergy develops under the influence of hereditary predisposition.The risk of developing the disease doubles if any of allergic parents, and if it is observed in both - the risk increases even doubled.However, the substance is an allergen for the child, may differ from the parent allergens.Food allergies are not a priority and can develop absolutely any kind of food, but the most common allergens include nuts (especially peanuts), wheat, soy, shellfish, fish, eggs and milk.There is also a so-called cross-allergy, which usually develops after a reaction to a specific allergen.For example, people who are allergic to peanuts, often become allergic against other legumes (lentils, soybeans, peas and so on.).
Often people have seen the development of allergies to chemicals such as the sulfites used to preserve the color of food (vegetables, dried fruit).Allergic reaction to sulfites appears irregular breathing and allergic shock after eating the food of their contents.Often sulfites cause severe bouts of serious illness such as asthma
Food allergies - symptoms
Since the adoption of food allergy-provoking food directly to an allergic reaction to it the body can go from a few minutes before hours.In case of severe allergy, odor, or a simple touch to eating cause acute allergic response.
Symptoms of food allergy include itching and swelling of the throat, mouth and lips.Annoying when food enters the digestive system causing symptoms such as diarrhea, nausea, vomiting, renal colic.Often there is redness of skin, hives, eczema, itchy skin.Some patients are likely to develop allergic rhinitis, which are peculiar to such phenomena as shortness of breath, cough and runny nose.
In some cases, a so-called delayed allergic reaction when symptoms after ingestion of the allergen begins to manifest itself through the hours or even days.When compared with immediate allergic response, the symptoms of delayed allergic reaction expressed not so much, and can include asthma, hives and eczema.
most dangerous, but fortunately a very rare condition with food allergies is anaphylactic shock.This condition includes allergic reaction several systems and organs of the human body.Symptoms of anaphylactic shock - decreased blood pressure, shortness of breath, swelling of the mucous membrane of the throat, sweating, rash, intense itching.If anaphylactic shock is not treated properly and quickly, the state is progressing very quickly, usually leads to loss of consciousness and sometimes death.
In the case of recurring allergic symptoms, you should carefully consider your daily diet and record everything eaten in a day, not forgetting to mark the cooking method and the amount of consumption of food.You should also record the time of occurrence and nature of allergy symptoms (nausea, urticaria, headache, itching and so on.).After an appeal to the allergist, to explore with him the recording data for the last two or three weeks, are more likely to turn out to identify dangerous products
products, often causing food allergies
One of the most potent allergensThey are nuts.For people prone to food allergies may serve as little consolation that food allergy is usually selective and allergic reaction can be only one kind of nuts.Sometimes sensitivity to nuts so strong that even a minor finding them in chocolate or cake can cause strong reactions.
potential allergens include berries, fruits and vegetables.The most active of them: black currants, blackberries, raspberries, strawberries, lemons, tangerines, peaches, melons, onions, peas, tomatoes.
Meat, even despite the high content of protein is rarely causes an allergic reaction, and lamb and beef less often, but the horse meat, chicken and pork - more often.Because of different protein composition, patients with food allergy to pork and mutton can safely eat beef.
also food allergies can be caused by fish and seafood, which is especially common in people living in coastal areas.Some patients thus have a heightened sensitivity when even the smell of the fish they develop asthma.For marine fish allergy develops much more often.There are cases of intolerance crayfish, prawns, eggs and products from them prepared.
very often leads to the use of food allergy chicken eggs, the body's sensitivity to an allergen can be so high that occasionally conventional bun or pastry, which is present in the test egg can cause bright allergic symptoms.Soft-boiled eggs cause food allergies more frequently than omelette and boiled eggs.In some cases, food allergies to egg can be combined with an allergic reaction to chicken.
most frequent cause of food allergy children - cow's milk.With age, a decrease in sensitivity to milk as an allergen.Sensitizing properties of milk reduces the boiling
Food allergies - treatment
If the treatment of food allergy did not start on time, with the passage of time can be observed phenomenon allergodermatita strongest.In addition, the range of allergens is constantly expanding.After two or three years to the possible accession of food allergy pollen allergy, and after that, home (for cosmetics, animal dander, dust, etc.).Often, the disease affects the respiratory system, leading to asthma, affects other systems and organs.
Treatment of food allergies in the first place is to reduce intoxication, which are used sorbents (eubikor, laktofiltrum, filtrum, enterosgel) and allergy (antihistamines) do not cause the side effects of medications (Telfast, Claritin, Kestin).These drugs must be taken exactly as prescribed physician.
Food allergy involves desirable complete exclusion from the diet of a dangerous allergen.If this is not possible, it is possible to adapt to the allergen.So, for example, one and a half years old baby, it is desirable not to give known allergenic foods (seafood, honey, nuts, chocolate, eggs, cow's milk).After reaching this age, you can use them, but should start with minimal doses (partial teaspoon).As a result - the body begins to gradually get used to the potential for a dangerous food and the presence of allergens not respond.
Unfortunately, allergic mood remains in the body for a lifetime, and will later manifest food allergy depends on nutrition, lifestyle, state of immune protection, residence.Up to three years, children with allergies should be fed exclusively with natural products.With timely lifting of immunity and nutrition, from allergic reactions can be eliminated.
