While vegetable oils may actually represent peanut oil, soybean oil, sunflower seed oil, corn oil or palm oil, in many cases prepared foods may list this ingredient simply as "vegetable oil. Generally, vegetable oils are highly refined, meaning that they are processed in such a way to remove the majority of the protein present in the crude raw form. The refining of vegetable oils decreases the amount of protein by approximately fold, which significantly decreases the chance of vegetable oils causing allergic reactions. Unfortunately, crude and some refined vegetable oils do contain some vegetable proteins, which may cause allergic reactions in very sensitive people with food allergies.
Avoidance of peanut is quite difficult and is it often a hidden ingredient in many prepared foods. The refining process of peanut oil virtually eliminates the presence of peanut protein; although even crude peanut oil contains a very small amount -- micrograms per milliliter — of peanut protein. None of the 62 patients studied reacted to refined peanut oil. Another study published in sought to determine if allergic antibodies to peanut in blood samples from people with peanut allergy would react to peanut protein found in peanut oil in a test called an immunoblot.

Reactions did occur, but only in blood samples with extremely high levels of allergic antibody to peanut. It is important to realize that this study looked at a blood test, rather than a test to see if a person with peanut allergy would experience an allergic reaction after eating peanut oil. Less information is available regarding soybean oil and allergic reactions, although there are a number of cases of allergic reactions reported in the medical literature to foods, as well as medications, that contained soybean oil.
It is likely that, similar to peanut, crude soybean oil contains more protein than refined soybean oil. While soy is considered to be a common food allergy, it is more of an issue in young children, and adults frequently outgrow peanut allergy.
Sunflower seed allergy is not particularly common, although I have seen a handful of patients in my practice recently with this type of food allergy. There are a few reports in the medical literature of people experiencing allergic reactions to sunflower seed oil, although a study published in found no reaction to crude or refined sunflower seed oil in two patients with known anaphylaxis after eating sunflower seeds. Sesame is becoming a more common food allergy in recent years, and like peanut allergy, severe allergic reactions are quite common as a result of sesame allergy.
Sesame seed oil is different than many of the other vegetable oils in that it is used as a flavoring for foods. For this reason, sesame seed oil is typically crude, and therefore contains significant sesame proteins. Allergic reactions to sesame seed oil have been reported in the medical literature. Therefore, a person with a sesame seed allergy should strictly avoid sesame seed oil. There are a number of other vegetable oils used in cooking and prepared foods.
These include corn oil, safflower oil, canola oil, palm oil, palm kernel oil, and coconut oil. With the exception of a single report of coconut oil allergy contained in a baby formula published in , there are no reports of food allergy to these vegetable oils published in the medical literature.
It is likely that these oils are refined and therefore contain little, if any, protein that could trigger an allergic reaction. Therefore, if a person is allergic to a particular food from which a vegetable oil is obtained such as peanut, soybean or sunflower , the crude oil should be avoided. Given that the refined oil contains little or no protein, it should be safe for this type of oil to be consumed.
In the case of sesame seed oil, or any other vegetable oil that is used to flavor a food, a person with sesame seed allergy should avoid consuming sesame seed oil.

Soybean Oil. Sunflower Seed Oil. Since then, milk has been the hardest to avoid. You're scared to let your child out of your sight. Like other kids with severe food allergies, Reagan would sit, often by herself, at the milk-free table during school lunch and snacktime. She'd tote her own cupcakes to parties, and restaurants were off-limits. That was then. Today, Reagan, now 11, can have all the milk and ice cream she wants.
The best day of her life? When she could finally eat pizza -- with real mozzarella cheese -- thanks to a revolutionary treatment for food allergies being developed at Johns Hopkins Childrens' Center, in Baltimore, by Robert A. Wood, M. A few other medical centers in the U.
Still in clinical trials, this so-called oral immunotherapy involves slowly desensitizing the immune system of highly allergic children by feeding them gradually increasing amounts of whatever they're allergic to, such as milk, peanut, or egg proteins, and slowly boosting their ability to tolerate the foods. Each week for a year, Roberts took her daughter to Dr. Wood's office. There, under close supervision, Reagan was given slowly increasing amounts of milk protein mixed with a chocolate or strawberry drink. She also got another premixed dose every evening, upping the amount in carefully calibrated increments.
From time to time, the doctor checked her blood levels for antibodies to milk; if they dropped, that was a good sign.
Though shots for seasonal allergies also known as immunotherapy are standard practice, the approach has proven risky for food allergies because reactions to the shots were too severe to justify continuing experiments. That's why the success of the oral approach is such big news. The treatment is at least ten years away from widespread use -- and not something to be tried at home -- but food-allergy experts haven't been this excited in a long time.
The drug is targeted at those age years old with a peanut allergy. It exposes kids to a small amount of peanuts every day, which should help build a tolerance and lessen the severity of symptoms after exposure. Five years ago, there wasn't a lot of research on preventing or treating food allergies. Thanks to groups such as the Food Allergy Initiative, which aims to find a cure by funding major studies, researchers know more than ever.
We're cautiously optimistic. One recent breakthrough comes from Parents advisor Hugh Sampson, M. What's more, when kids eat these items they also develop a tolerance to all milk products. Sampson is now conducting another study to confirm this.

If the finding turns out to be true, "it will change the current paradigm for treating milk-allergic children," he says. But the urgency for research has been driven by unsettling statistics. One study found that nearly 8 percent of children under age 18 have food allergies.
Another reported an 18 percent jump in food allergies in kids of the same age over a period of a single decade. Doctors aren't sure what accounts for the spike in cases, though everything from environmental pollutants to society's obsession with hygiene has been blamed.

Having a child with a food allergy exacts a huge emotional toll. That discovery changes everything: birthday parties, school trips, grocery shopping, and holidays with your family.
I was petrified and in denial. I didn't think I was up to the task of monitoring every morsel of food that came near my child. Kids have an allergic response when their immune system overreacts to foods that are usually harmless.
Symptoms often appear within minutes, though it can take as long as two hours. They range from a mild rash, tingling in the mouth, and diarrhea, cramps, and bloating, to anaphylaxis, a potentially fatal reaction in which several systems of the body lungs, stomach, skin, heart react simultaneously. You use the EpiPen and then rush to the hospital," says Lenner, referring to the device with a dose of the drug epinephrine. Injected through a child's clothing into his thigh, it can stop anaphylaxis.
Doctors suggest having two EpiPens to be safe. Isaac wears his on his belt; his teacher and the school nurse each have one too. While just about any food can trigger an allergic reaction in children who are predisposed to it, roughly 90 percent of reactions are caused by the foods known as The Big 8: milk, eggs, peanuts, tree nuts pecans, almonds, walnuts, cashews, pistachios , fish, shellfish, soy, and wheat. Burks, a member of FAAN's medical advisory board.
And as our palate becomes more sophisticated, the list of foods kids are allergic to is growing too.
