Peanuts often take center stage in conversations about food allergies. That's because the nuts are a common food that’s hard to avoid—and allergies to it are severe and usually lifelong, says Scott Sicherer, M.D., director of the Jaffe Food Allergy Institute at the Icahn School of Medicine at Mount Sinai in New York. Peanut allergies cause more cases of anaphylaxis—a severe allergic response that can restrict one’s airway and cause nausea, low blood pressure, and cardiac arrest—than any other food allergy in kids.

What Are Peanut and Tree Nut Allergies ? Peanuts are among the most common allergy -causing foods, and they often find their way into things For this reason, people who are allergic to peanuts can also be allergic to tree nuts, such as almonds, Brazil nuts, walnuts, hazelnuts, macadamia nuts

There’s no cure for this increasingly common condition. But Sicherer says researchers have been looking for ways to reduce its severity to make it less dangerous.

A new study published last month revealed that one treatment researchers were trying, called oral immunotherapy—where patients take tiny doses of peanut protein in an attempt to “desensitize” them to the allergen—may help to reduce the severity of the allergy. However, the study also found that the treatment is risky, and can trigger an anaphylactic reaction—the severe allergic response that can restrict one’s airway and cause nausea, low blood pressure and cardiac arrest.

“It means that there could be limitations to pursuing peanut oral immunotherapy, and it might not be for everyone,” says study author Derek Chu, a clinical immunology and allergy resident at McMaster University in Ontario, Canada.

20 Genius Ways to Use Peanut Butter That Aren't PB&J

20 Genius Ways to Use Peanut Butter That Aren't PB&J Step away from the crustless white bread. These peanut butter hacks and recipes aren’t just nutty—they’re delicious. According to the USDA, the average American ate 7.5 pounds of peanuts last year, which is a higher amount than ever before. And from the approximate 2.5 million metric tons of peanuts that the United States consumed, over 60% of those peanutscame in the form of peanut butter. Clearly, Americans love peanut butter. It’s a childhood favorite that we’ll just never get over. What we have gotten sick of, though, are peanut butter and jelly sandwiches.

Allergy experts are reversing their position on how best to treat and prevent peanut allergies in kids: don't avoid peanuts . In one, the rate of peanut allergies was about 10 times lower for children who ate peanuts from an early age, compared to kids whose parents avoided giving their infants peanuts .

Talk to your allergist about how to stay safe in the school cafeteria. Also ask about how you should handle other peanut encounters, like at restaurants or stadiums where people are opening peanut shells. People with nut allergies usually won't have a reaction if they breathe in small particles.

In the meantime, researchers have also been studying ways to prevent peanut allergies in the first place, prompting both the American Academy of Pediatrics and National Institute of Allergy and Infectious Diseases to issue new recommendations for parents on when to feed children peanuts to prevent the allergy from developing.

Why the Peanut Problem?

In 1999, a study published in the Journal of Allergy and Clinical Immunology found that less than half of 1 percent of children under the age of 18 were allergic to peanuts. But by 2010, a follow-up study revealed that the number had risen to 2 percent, which translates to over 3 million adults and children in the U.S. Researchers don’t know why peanut allergies have become more common, though some speculate that the increased use of antibiotics or living in environments that don’t expose kids to enough germs and dirt might play a role.

If approved, a new treatment for peanut allergy may enable kids to eat small amounts of peanuts without a severe allergic reaction. Exposure to trace amounts of peanuts in cookies, cakes, or other foods from cross contamination can end with a severe allergic reaction and even hospitalization.

At the moment, kids with peanut allergies generally must avoid foods that contain any trace of peanuts. To prevent accidental exposure, some schools in the U.S. have implemented peanut-free policies, and airlines such as Southwest and American have stopped serving packaged peanuts on flights. In case they do come into contact with peanuts, allergic people must always carry an auto-injector of the hormone epinephrine (such as the EpiPen or Auvi-Q) to use if an anaphylactic reaction occurs. Epinephrine reverses the symptoms of a reaction by constricting blood vessels (raising blood pressure) and relaxing the muscles in the airway (to help a person breathe).

However, even though many allergic people experience reactions at some point during their lives, very few die from one. People without allergies are more likely to suffer an accidental death than people with allergies are to die from a food allergy, according to a 2013 analysis. Only 11 people in the U.S. died from peanut or other food allergies in 2005, the last year data are available.

Reducing the Severity of the Problem

Allergists and researchers see immunotherapy as a promising way to reduce that dangerous reaction to peanuts. It has been used for years by people who are allergic to pollen or bee venom, Chu says. In those cases, they get shots that deliver tiny doses of the allergen.

The No-Bake Peanut Butter Pie That Made Me Stop Hating Peanut Butter

The No-Bake Peanut Butter Pie That Made Me Stop Hating Peanut Butter For as long as I could remember, I abhorred peanut butter. To me it tasted harsh, almost metallic, and I hated the texture. Peanut butter felt more like a prank than a food. It reminded me of how my dad—a lifelong practical joker—would tell his unknowing friends that wasabi was “Japanase avocado” when they went to sushi bars. My Texan mother really tried hard to assimilate me through food when we moved to the United States from Peru. I grew to love certain things, like fresh milk (as opposed to the more traditional canned). Others I’d merely accept or suffer starvation for the night, like her thrifty tuna casserole.

But when it comes to peanuts, immunotherapy treatment is still experimental, he stresses. Chu and his colleagues analyzed 12 studies of the treatment to gauge its effectiveness and safety, and published their findings in The Lancet.

The good news is that their analysis found that immunotherapy could successfully desensitize patients to peanuts—meaning they could begin to include peanut products in their diet without a reaction after treatment. But during immunotherapy treatment, there were risks: While those with allergies who just avoided peanuts had a 7 percent risk of having an allergic reaction over the course of the trial, that number jumped to 23 percent for those who were receiving immunotherapy.

At the moment, the National Institute of Allergy and Infectious Diseases doesn't recommend oral immunotherapy for peanut allergies, and the therapy isn't approved by the Food and Drug Administration. However, it's offered by some allergists in the U.S.

“Patients considering immunotherapy should first know the facts, not just the claims or anecdotes,” Chu says. “The unfortunate reality is that there is some predatory behavior out there targeting patients seeking guidance.” Carefully review the claims made by doctors, particularly if they claim to have a “foolproof” oral immunotherapy method, he says, and determine if they have any financial conflicts of interest.

A Patient's Guide to Allergies

A Patient's Guide to Allergies Tens of millions of Americans suffer from allergies, whether the problem is pollen or peanuts.

There are clinical trials of oral immunotherapy, Chu says. They're carefully controlled, and the results might benefit people with allergies. You can find a list of clinical trials at clinicaltrials.gov. Doctors may know of others than aren't publicly posted.

If you're considering oral immunotherapy, make decisions in partnership with your allergist and other health professionals, says Michael Pistiner, M.D., director of food allergy advocacy, education, and prevention in the Food Allergy Center at Massachusetts General Hospital. “We need this shared decision-making because we’re at a time of uncertainty,” he says.

There’s much more to learn about oral immunotherapy. “We need to understand its safety, we need to know what is the best dose, who is the best candidate, why do some kids do better than others, and what’s the best age,” Pistiner says.

Can You Prevent Peanut Allergies?

While researchers aren’t sure what causes peanut allergies, they have identified a few risk factors and are studying how to prevent allergies in the first place in people at high risk. For example, infants who suffer from eczema, a skin condition thought to be caused by a combination of genetic and environmental factors, may be more likely to develop a peanut allergy. And infants who are allergic to eggs are also at an increased risk, according to the National Institute of Allergy and Infectious Diseases (NIAID).

For these babies at high risk, the American Academy of Pediatrics now recommends that parents begin feeding them peanut products by 4 to 6 months of age to reduce their chances of developing a peanut allergy.

The Reason Anxious People Often Have Allergies

The Reason Anxious People Often Have Allergies There might be a hidden link between seasonal sniffles and mood disorders.

The recommendations are based on a 2015 study known as the LEAP trial, or Learning Early About Peanut Allergy. The theory is that eating peanut products early on helps the body learn that it’s a food that’s safe. “The immune system sees it, but doesn’t attack it,” Sicherer says.

NIAID used the LEAP study to develop guidelines, endorsed by the American Academy of Pediatrics, on the best way to prevent allergies. There are different recommendations for babies at high and moderate risk of allergies and those who aren’t at an elevated risk.

High-risk infants should be tested for peanut allergies before the first introduction of food, either with a blood test or skin-prick test, to see whether they have already developed the allergy. If the tests don’t show a peanut allergy, the nuts can be introduced either at home or—if a parent is concerned—in a doctor’s office. If a skin-prick test shows that the infant might have an allergy, the guidelines recommend that he or she should still be fed peanuts, but only in a doctor’s office.

Infants who have mild or moderate eczema and therefore have some risk of developing a peanut allergy—but not as high—should start eating peanut-containing foods around 6 months of age. If an infant doesn’t have eczema, peanuts should be treated like any other food; they can be added to a diet when the family prefers.

And last, babies shouldn't be fed whole peanuts or plain peanut butter straight from the jar, because they're choking hazards for those younger than 1 year old, Sicherer says. Instead, they can be fed foods cooked with peanuts, such as peanut butter mixed into oatmeal.
