The truth about food allergies
You eat one of your favorite foods, as usual. You feel funny after 20 minutes. Not always. A look in the mirror shows that your lips are swollen beyond proportions, Angelina Jolie is certainly not common.
As shocked as you might, perhaps, the truth is that “you could wake up tomorrow morning with an allergy to something you ate the whole life,” said Melinda M. Rathkopf, MD, Faaa, FACA, FAAP, of Allergy, Asthma and Immunology Center of Alaska and assistant clinical professor at the University of Washington.
Although, according to the FDA, and adult food allergy occurs in only 2 percent of the population that is growing. The reasons for this are unclear, but experts have theories. The first is that negative reactions to pollen allergy in stock: Rathkopf said that if you are allergic to birch pollen, and ragweed or eating fruits and vegetables that you or a protein similar to that found in pollen, your body can confuse fruits and vegetables to environmental allergens. An allergic reaction then follows, the origin of his mouth for the itching and tingling.
Another theory is that the increase of food allergies in adults is a byproduct of better hygiene. “Our daily life now includes many ways to keep healthy germs, such as the use of many antibiotics and be free from the farm or jungle living with exposure to germs” Scott H. said drying section, MD, associate professor of pediatrics at the Jaffe Food Allergy Institute Mount Sinai School of Medicine. “As such, our immune system to fight germs is ill at less busy and probably wrong to attack the protein in food safety, animal dander, pollen, etc.”
Despite the vagueness of its causes, what happens in the body during a reaction is not a mystery. “A food allergy occurs when a class antibody called immunoglobulin E (IgE) or other immune cells, called T cell encounters a protein food, is recognized and triggers an immune response,” said Matthew Jason Greenhawt , MD, MBA, clinical professor at the University of Michigan School of Medicine, Division of Allergy and Clinical Immunology. In other words, the body mistakes proteins from certain foods for something harmful and immune system wage an attack.
“Part of this attack is the creation of antibodies against food, which means that the next time you eat food, even in very small amounts, the antibodies are on alert to inform the immune system to react,” said Willow Jarosh MS , RD, CDN, C & J Nutrition in New York City. “Is this the immune response that leads to the symptoms of an allergic reaction.”
Identifying allergies
The persistent urticaria and pruritus are the most common annoying the most visible and most immediate adverse reactions to food. And it can take six to eight weeks, even with treatment. “You need that time to stop what is going on internally that trigger the allergic reaction,” says dermatologist Audrey Kunin, MD. Kunin plan of treatment is oral antihistamines, Benadryl prescription options such as Atarax, especially for women, like syrup versions for children, which allow patients to monitor more easily their strength and balance with drowsiness they cause. At times I also prescribe a topical cortisone cream. “Hot baths also help.” Aveeno oatmeal bath or baking soda baths can be very refreshing, “said Kunin.
Other symptoms of food allergy are nasal congestion, wheezing, cramps, vomiting and / or low blood pressure, says Rathkopf. Reactions can range from mild to severe with most of anaphylaxis more dangerous, where “blood pressure falls dangerously low and the throat swells, it is difficult to breathe,” Jarosh said. Approximately 150 people die every year from an allergic reaction, is essential to consult a doctor if you think you’ve reached a food allergy. Blocking the cause of adverse reactions can be a tedious process, for example, can con-reactive allergy and the torch when it comes into contact with two specific things at once, but a board certified allergist can go following the problem through the skin test or blood and throwing things out of your diet one by one through a food challenge.
