Rare and unusual food allergies — learn about what they are, what causes them, and the associated symptoms red itchy hives on skin

Allan was enjoying a family dinner of T-bone steak, mashed potatoes, and steamed vegetables. Different hives Shortly after the meal, his palms began to sweat and his body broke out in hives. Hives on face only His wife called the emergency nurse hotline associated with his medical insurance, who then suggested Allan go to the nearest emergency department. Hives urticaria treatment But Allan took an antihistamine, decided he felt better, and stayed home.


Two weeks later, Allan began experiencing the same symptoms after eating a porterhouse steak, baked potato, and half a bottle of wine. Contagious hives like rash He drove himself to the nearest emergency department. Painful hives on body Following a series of tests, the physicians couldn’t pinpoint the cause of the reaction.

However, after experiencing several more—although less severe—reactions, Allan visited an allergist. Hives painful When asked whether he spends much time outdoors, Allan said yes and that he enjoys hiking and camping in the spring and summer. Skin hives and rashes His allergist said he may have gotten a tick bite—the type that causes allergic reactions whenever you eat red meat.

Millions of people in the United States experience food allergies and adverse food reactions. Severe hives The “big eight” allergens—milk, eggs, peanuts, tree nuts, shellfish, fish, wheat, and soy—cause about 90% of reactions. Hives on neck and arms However, according to the Centers for Disease Control and Prevention, more than 160 foods have caused food allergy reactions,1 demonstrating that many people react to foods that seem well outside the realm of the usual suspects. Fever with hives Are they true food allergies? Is there something else going on?

Red meat allergy, as in Allan’s case, has captured the attention of the media over the past couple of years as researchers have worked to identify its cause. What is hives rash Because this type of allergy is so rare, it’s often overlooked and therefore underdiagnosed.

Typically, a red meat allergy involves a delayed reaction that can occur many hours after ingestion, although this isn’t always the case.2 In fact, in a study involving 24 subjects who tested positive for sensitivity to the carbohydrate alpha-galactose, symptoms were confirmed three to six hours after eating beef, lamb, or pork.2 Among these participants, common symptoms included nausea, vomiting, and diarrhea, with the most common being itching. Why do you get hives on your face Anaphylaxis was common in all 24 patients, which was exacerbated by exercise in at least two cases.

Diagnosing a red meat allergy can be challenging because of the delay between ingestion and symptom onset. What causes hives on the face However, a detailed history can be an important part of the puzzle. How to get rid of hives from stress In addition, individuals with a true red meat allergy will test positive following an immunoglobulin E skin prick test. Hives caused by Working with an allergist is an important part of obtaining an accurate diagnosis.

Interestingly, in the above study, 80% of patients had been bitten by ticks before the onset of symptoms.2 In a different study of children between the ages of 4 and 17, nearly all who tested positive for sensitization to alpha-galactose, beef, and pork (among other potential allergens) also had been bitten by ticks.3 Researchers now believe that exposure to ticks may be the cause of this unusual food allergy. Chronic hives in children Those most likely to be affected include individuals who live in the Southeast; however, tick-induced red meat allergy has been described in locations such as Australia, too.2

Like other severe food allergies, the only treatments at this time are avoidance and symptom management with antihistamines for mild symptoms and epinephrine for anaphylaxis.

Dietitians should provide counseling on the importance of abstaining from eating the offending food as well as appropriate substitutions. Causes of hives in adults stress Clients may need help identifying hidden sources of the food and understanding that even small amounts can provoke a serious and/or life-threatening allergic response.

Marianne Smith-Edge, MS, RD, LD, FADA, senior vice president of nutrition and food safety for the International Food Information Council & Foundation, recalls working with a client who had soy and red meat allergy and who didn’t want to believe he was allergic to beef. Bruising hives photos “He told me, ‘I can’t be allergic to red meat. Skin allergy hives I eat hamburger every day,’” she says.

The patient had visited the emergency department twice for reactions before he finally was diagnosed with the allergy. Hives on lower body only The patient’s allergist instructed him to see a dietitian and stop eating beef and soy-based foods. Hives and hormones His dietitian worked with him and his wife, who was the primary shopper and cook, to help them understand that his food allergy was real and potentially severe. Red hives on chest By focusing on his overall health and the benefits he’d reap by omitting red meat from his diet, he finally complied.

A patient once reported itching in her mouth and throat when she ate most fruits and vegetables, so she stopped eating the ones she thought were causing this reaction. Allergic reaction with hives Raw fruits and vegetables caused much more discomfort than cooked. Hives and allergies It turns out the patient had severe pollen allergies for which she took prescription medication and was advised to visit an allergist to rule out food allergy.

For many people, environmental allergies such as this can masquerade as food allergies. What to do when you have hives For example, individuals with an allergy to birch tree pollen can have symptoms that mimic food allergies when they eat raw fruits and vegetables. Types of hives The pollen is present in or on the skin of the fruits and vegetables. Hives on eyelids They’re either cross-contaminated with birch tree pollen or contain proteins that are similar in structure to birch tree pollen that can cause sensitive individuals to experience intense itching in the mouth and throat in the case of the above patient, known as oral allergy syndrome (OAS) or pollen food syndrome.

Cross-reactivity, such as between birch tree pollen and apples, is the term used when antibodies are released in response to a protein or constituent that’s similar to the protein responsible for the true allergy. Alcohol hives treatment Proteins that are similar to one another can confuse the immune system, causing it to react to the wrong substance. Hives fever nausea People who experience this syndrome often aren’t taken seriously, since some clinicians assume that they’re just trying to avoid eating fruits and vegetables.

Typically, symptoms are contained in the oral cavity and are self-limiting, quickly resolving on their own once the individual stops eating the offending food. Baby with hives and fever Severe reactions are possible, particularly if epiglottal swelling is involved, since this can cause breathing difficulty.4 Those who believe they have OAS should be evaluated by an allergist to rule out food allergy.

It’s common for many individuals who experience OAS to believe they’re allergic to fruits and vegetables, but they don’t have to avoid them. Painful hives on palms of hands Dietitians should instruct clients to wash raw fruits and vegetables well or remove their skin, experiment with cooked vs. What helps hives raw, and avoid the ones that continue to cause reactions. Skin hives pics RDs can help clients choose fruits, vegetables, and other foods that are both nutritious and acceptable for regular consumption.

Dietitians know that spices not only help make foods taste better but also add various health benefits. Itchy hives on hands However, for a small percentage of people, spices can cause dangerous allergic reactions if ingested. Treatment of hives Coriander is in the family of spices that includes caraway, fennel, and celery—all of which have been implicated in allergic reactions in recent years, and they’re not alone. Nervous hives pics Cinnamon, saffron, and mustard also have been noted for causing reactions. Pictures of stress hives Depending on the country in question, spices have become some of the most common food allergens.

For instance, a study in Spain showed that a group of 38 subjects had a clinically significant allergy to mustard.5 Like OAS, allergy to spices appears to be related to cross-reactivity to birch tree pollen but also may be associated with mugwort and ragweed pollen allergy.6 In fact, the researchers in Spain believe mustard allergy likely is linked with sensitization to mugwort pollen and other members of the Brassicaceae family (to which mustard belongs) or possibly to other unrelated plant species. Symptoms of hives from stress Several subjects experienced food-induced anaphylaxis after eating mustard-containing foods.

In Europe, celery allergy is relatively common and therefore considered a top allergen. Getting hives at night According to The Anaphylaxis Campaign, 30% to 40% of allergic individuals are sensitized to celery.7 Sensitization doesn’t necessarily indicate a clinical food allergy, but the potential for anaphylaxis is present. Leg hives Similar to other spice allergies, celery allergy is thought to be associated with mugwort allergy.

Spice allergy symptoms are similar to hay fever, but they can be much more severe. Medicine for hives itching And since spices are ubiquitous in foods, it can be difficult to identify the source of the reaction and avoid the offending spices. Antihistamines for hives adults Dietitians must be able to help clients understand the importance of reading labels each time they purchase a product and avoid foods that may not indicate which spices have been added. What can trigger hives Indian and Asian foods can present the most danger since they include common spices that cause allergy, so recommending that clients prepare meals at home will be helpful. Hives cure home remedies The only treatment for spice allergies is to avoid the offending foods and symptom management.

According to the American Latex Allergy Association, a natural rubber latex allergy often results when sensitized individuals are exposed to one or more proteins that occur naturally in raw latex preparations. Hives on babies About 8% to 17% of health care workers, 68% of spina bifida patients, and less than 1% of children or adults in the general population have a latex allergy.8 Latex allergy can be severe and cause anaphylaxis.

What does latex have to do with food allergies? As much as 50% of those with an allergy to natural rubber latex also will have cross-reactivity to certain foods, according to Isabel Skypala, BSc, RD, and Carina Venter, BSc, PhD, RD, authors of the book Food Hypersensitivity: Diagnosing and Managing Allergies and Intolerance.6 Individuals with latex allergy have an increased risk of developing food allergy reactions, most commonly to avocados, bananas, chestnuts, and kiwis, but sensitivity to apples, carrots, celery, melons, papaya, potatoes, tomatoes, and various other foods has been recorded. Rash hives toddler Many proteins are found in natural rubber latex, so food proteins that are structurally similar to one or more of these proteins have the potential to cause cross-reactivity.

People with sensitivity to these foods based on a latex allergy usually experience symptoms within minutes of ingestion. Is hives serious Reactions to natural rubber latex allergy can be life threatening; however, food allergy related to latex allergy usually is less severe. Remedies for hives Treatment involves avoiding these foods once a diagnosis has been confirmed. Hives reaction time In some hospitals, latex allergy protocol includes avoiding these commonly allergenic foods for this at-risk population.

The subject of chocolate allergy often is debated. Hives itchy skin rash The fact that chocolate typically is processed in such a way as to extensively dilute or remove potentially allergenic proteins indicates that most people won’t be clinically allergic to chocolate. Hives disease However, Skypala and Venter suggest that this may not be the case with gourmet chocolates, which contain more of the whole cacao bean.6 In reality, it’s much more likely that individuals will be sensitive or allergic to one or more constituents of chocolate, such as milk or nuts.

Allergic reactions vary based on the true nature of the food allergy. What can cause hives on skin An allergy to milk or nuts in the chocolate can result in anaphylaxis. Skin hives pictures It’s essential for dietitians to take a complete and accurate food history to determine whether someone is sensitive to chocolate or some other substance in it. Cure for hives on skin If necessary, dietitians should encourage avoidance along with additional testing with a qualified allergist.

The scientific community still has much to learn about food allergies, including these rare and unusual ones. Facial hives and leukemia Basic questions continue to go unanswered, such as what causes food allergies? Can they be prevented? Are rare reactions the result of food allergy, cross-reactivity, or some other complex immune reaction yet to be defined? For now, it’s important to remember that a true food allergy is an immune system reaction that can have severe consequences if not managed.

Since clients can have adverse food reactions to any food, dietitians shouldn’t assume that because it sounds unusual, it isn’t a real medical issue. Autoimmune hives treatment Food allergies, like all others, can be unpredictable, so work with a qualified allergist and help clients take the necessary precautions to stay safe. What causes hives on skin Suggest they carefully read product labels and carry epinephrine with them at all times in case of anaphylaxis. Have hives And help clients put food allergy into its proper context, focusing on an overall diverse, nutritious, and liberal diet to maintain good health and a high quality of life.
