Food Allergy Doctor in NYC

Safe, Effective Treatment for Food Allergies

Food allergies affect 32 million Americans. More than 50% of adults with food allergies and more than 40% of children with food allergies have experienced a severe reaction. In fact, data suggests that the prevalence of food allergy may be increasing with a large percentage of school-age children at risk for anaphylaxis. And there are NEW exciting treatments that can greatly improve the life of anyone with food allergies.

There Has Never Been an Effective or Safe Treatment for Food Allergies Until Now!

Our NY allergy practice specializes in solving difficult cases through the latest technology in testing and compassionate care. That’s why we are known as The Allergy Detectives. There has been an increase in food allergies as people, in general, are becoming more allergic. Food allergies can cause very serious symptoms including anaphylaxis, seizures, comas and even death.

Dr. Dean Mitchell, M.D., board-certified allergist, specializes in food allergies, including difficult cases, and can help you manage your food allergy so that you are less likely to have an allergic reaction or suffer from severe symptoms.

Food Allergy Treatment

Food allergies are the most urgent problem in the field of allergy today. They cause anguish, embarrassment and in some cases heartbreak to families. Until very recently, whenever a patient told me they had a food allergy the best I could recommend was avoidance – not anymore!

Now there is a treatment available to patients with dangerous food allergies!

  • Sublingual immunotherapy or SLIT
  • Oral allergy immunotherapy or OIT

Sublingual Immunotherapy – Allergy Drops Treatment

Sublingual immunotherapy or allergy drops treatment desensitizes patients to their allergy over time using liquid drops. The allergy drops are placed under the tongue and gradually build up a tolerance to the allergen in the body. The beauty of this treatment is that it is very safe and patients can do this at home. And now studies have come out showing that sublingual immunotherapy (SLIT) works for food allergies.

Oral Allergy Immunotherapy

Another option for patients with severe food allergies is oral allergy immunotherapy. This treatment method involves the patient ingesting high doses of peanut flour protein capsules over time (this can be done with other foods as well).

Understanding Food Allergies & What Causes Food Allergies

Food allergies can cause very serious symptoms, including anaphylaxis, seizures, coma, and even death. In fact, every 3 minutes a food allergy reaction sends someone to the emergency room. Food allergies happen when your immune system overreacts to a harmless food protein – an allergen.

And these reactions don’t necessarily happen the first time your body is exposed to a food protein. Over time and by repeated exposure the body’s immune system can become “sensitized” so that the body will no longer tolerate a certain agent even though it was fine when it was exposed to that agent before.

Signs and Symptoms of Food Allergies

  • Skin rashes such as hives or eczema
  • Itching in the mouth
  • Vomiting or diarrhea during or shortly after a meal
  • Shortness of breath, wheezing, or swelling that develops during a meal or shortly afterward

Among all the reactions to food that can occur, the respiratory responses are the most dangerous and frightening.

How We Diagnose Food Allergies

Take a Detailed History

Look for genetic and lifestyle risk factors for food allergies. Your history takes into account foods you are eating—because that’s where the culprit is likely to be. For example, in the United States, wheat allergy is much more common than in China, because we eat so much pizza, pasta, and bread. In China, the number one food allergy is, you guessed it, rice.

Rule out Sensitivity to Food

This is different than a true allergy and often confused. There are various common food sensitivities including lactose intolerance, gluten sensitivity (in severe cases, it’s called Celiac disease) and gastrointestinal reflux (GERD). The symptoms tend to be different and can include digestive problems like gas and pain, nausea, as well as itching, or even joint pain, headaches, rashes, and anemia.

New Advances in Testing

The innovative way to test for food allergies is through blood testing. The most precise tests available, called ImmunoCAP and ISAC by Phadia, measure the specific allergen components. The blood is drawn and sent to a lab to be analyzed for levels of individual protein components of the allergen. This is important because being allergic to some protein components is more dangerous than others.

The advantages of blood tests are that they are accurate and safe. You’re not exposed to the allergen, so there’s no risk of having a severe reaction to the test. The ISAC test, in particular, does precise component testing of specific food and environmental allergens. This gives the advantage of avoiding false cross-reacting positive test and gives a quantified level of specific allergen.

Testing for Food Allergies

This can be done in two ways. One of the older ways is called skin-prick testing. This is where a drop of a liquid allergen is placed on the surface of the skin and gently pricked with a plastic tooth-pick device. If your skin develops an itchy, red wheal (bump), then this could mean you’re allergic to the particular allergen. This does come with a small risk of having a severe reaction to the allergen.

Traditional Food Allergy Treatments

Until recently there are no real cures for food allergies. The best treatment advice for food allergies was always avoidance and keeping an EpiPen on hand in case you accidentally ingested the food allergen you are allergic to.


Even with the most diligent parents, avoidance is not 100% protection. One of my patients was a five-year-old boy named Timmy. He was allergic to peanuts, and his mother was always careful and hyper-vigilant. But one day she took Timmy to an ice cream shop and ordered him a sundae specifying no nuts. After his second spoonful, Timmy said, “Mommy, I don’t feel good.” He began to break out in hives all over his body and was wheezing loudly. She quickly checked the sundae and saw bottom Reese’s Pieces at the bottom, which contains peanuts. She raced him to the nearest hospital, where I met them. He immediately received a dose of adrenalin and his symptoms subsided.

Avoidance means that parents and the patients themselves have to be careful about what they eat.

The tragedies of stories of patients with peanut allergies who died because they ate a food unknowingly containing peanut are too numerous to detail. The Food Allergy & Anaphylaxis Network is a great organization that puts out alerts when a food product has been contaminated with a potential allergen and offers excellent updates of new laws protecting food allergy patients.


If you or your child has a severe food allergy, you should carry an injectable epinephrine known as an EpiPen or Twin-Jet. This medication can be purchased with a physician’s prescription, and the patient should be shown when and how to use it in the office. If you do need to use it, seek medical attention afterward for observation. If your food allergy is less severe, and you develop hives, for example, you can take an oral antihistamine like Claritin.

Get Tested

The new blood-testing technology we use in our NYC and Long Island offices can pinpoint the specific food allergy you are sensitive to. Knowing what the source is and how sensitive you are can help to avoid exposure. To get tested, contact us today.

High-Risk Factors of Having Food Allergies

  • Genetics: A child with one allergic parent has a 33% chance of developing allergies. With both parents having allergies, 70%.
  • Environmental Factors: The way a food is prepared can make it more or less allergenic. For instance, dry-roasted peanuts are more allergenic than raw or boiled peanuts. Skin exposure to food like peanuts can raise your risk (many soaps, shampoos or other products have peanut oil in them). Stomach acidity and bacteria flora in the gut are also important factors in food allergies.
  • Antibiotics: New studies show that taking antibiotics early in life can “clean out” helpful gut flora, making a child more susceptible to developing food allergies. A number of studies have found that taking probiotics can restore good flora and decrease the chances of developing food allergies. Long-term antibiotic use can also result in Candida overgrowth.
