The American Dietetics Association offers these tips for dealing with foodallergies when your family is eating away from home:

  • Let your server know from the beginning about your child’s food allergy. He or she should know how each dish is prepared and what ingredients are used. Ask about preparation and ingredients before you order. If your server does not know this information or seems unsure of it, ask to speak to the manager or the chef.

  • Avoid buffet-style or family-style service, as there may be cross-contamination of foods from using the same utensils for different dishes.

  • Avoid fried foods, as the same oil may be used to fry several different foods.

Egg Allergy: Someone With An Egg Allergy Can Get A Flu Shot

The American College of Allergy, Asthma and Immunology estimates as many as 2 percent of children are allergic to eggs. They also estimate as many as 70 percent of children with an egg allergy outgrow the condition by age 16. Egg is a common ingredient in many foods, so people with an egg allergy must always remain vigilant and carefully read food labels, Andrew said.

In the past, the flu vaccine contained a small amount of egg protein. Now, the flu vaccine contains no egg, so individuals with an egg allergy can and should get the vaccination.

What Are Some Walnut Allergy Symptoms

Food allergies occur when the immune system identifies the proteins in a particular food as harmful to the body, subsequently reacting to try to “fight off” the “harmful” proteins . Tree nuts, among which walnuts are included, are one of the “big eight” allergens that cause 90 percent of all food allergies. While people sometimes outgrow food allergies, tree nut allergies are almost always life-long. Nut allergies can be severe and even life-threatening.

Some symptoms of a walnut allergy include:

  • Itching or swelling of the mouth, tongue or lips
  • Skin reactions
  • Gastrointestinal symptoms
  • Respiratory symptoms
  • Cardiovascular symptoms

If you experience symptoms of anaphylaxis, which include nausea, vomiting, weak or rapid pulse, difficulty breathing, confusion and loss of consciousness, seek immediate medical attention, as this can be fatal.

  • non-IgE-mediated food allergy these allergic reactions arenât caused by immunoglobulin E, but by other cells in the immune system. This type of allergy is often difficult to diagnose as symptoms take much longer to develop .

A milk allergy is when the immune system does not recognize dairy and attacks it by releasing histamines. Someone with a milk allergy can develop severe symptoms, such as breathing complications or an uneven heartbeat.

A milk allergy is not to be confused with lactose intolerance, Andrew said. When someone is lactose intolerant, lactosea type of sugar found in dairy productsmoves through the large intestine without being properly digested. It can lead to uncomfortable symptoms such as gas, bloating or indigestion. When someone is allergic to milk and dairy products, the symptoms affect more than the digestive tract.

Diagnosis Of Nut Allergy

Patients medical history and physical exam are done. The patient is asked a lot of questions, such as the quantity and type of food consumed and how soon the symptoms started, the severity and duration of the symptoms.

Skin prick test is done to confirm allergy. Patient is instructed not to take antihistamines on the day of this test, as it can interfere or subdue any allergic response to the test. A drop of nut extract solution is applied to the patients skin then a needle prick is made through this drop. This will cause a small amount of the solution to enter into the skin. Patients having an allergy to nuts will experience an allergic reaction within 20-30 minutes. When the skin under the drop becomes itchy and red, then the skin prick test is considered positive. There also may be a raised, white colored swelling known as weal around the red area which takes about 15-20 minutes to reach its maximum size, and recedes over a few hours. If the skin remains normal then the skin prick test is considered to be negative.

Blood Tests such as ELISA test or a RAST test can be done to measure IgE antibody, which is a protein produced as a result of an allergic reaction.

The immune system overreacts when it comes in contact with the nuts or any other allergen. The allergic reaction from the nuts can be mild or severe. Anaphylaxis is a severe allergic reaction to nuts, which is a potentially life-threatening situation. Patient has symptoms usually within a few minutes or an hour after coming into contact with a nut.

Patient with nut allergy should always avoid nuts and foods that contain nuts to prevent an allergic reaction. However, if there is an allergic reaction after accidently coming in contact with the nuts, then treatment should be started immediately to decrease the risks.

How Long Does Allergy Season last? — From the makers of ZYRTEC®

Most food allergy related symptoms often start within minutes of ingestion, but some first symptoms can occur within two hours. Sometimes food allergy symptoms come in a second wave, which is called a biphasic reaction. The second wave of allergy symptoms can occur four to six hours after the ingestion of the allergen, so people, especially young children, need to be kept under close observation until then.

How To Avoid A Reaction

If you know you have a severe peanut allergy, the best way to prevent anaphylaxis is to avoid them. Here are a few tips:

  • Every time you shop, read food labels carefully. Packaged foods that contain peanuts are required to include them in the ingredients list.
  • When you order food in restaurants, always let the server know that you have a peanut allergy. Ask for your food to be prepared without peanuts, peanut oil, and other peanut-based products.
  • When traveling by plane, contact the airline and alert them to your allergy ahead of time. You can request that your flight be peanut-free and ask to have your seat cleaned.

As a precaution, always keep an epinephrine auto-injector nearby. This medication can reverse the symptoms of an anaphylactic reaction, but you have to use it quickly for it to be effective.

During a delayed reaction, you may need to administer a second and possibly third dose of epinephrine. See your allergist to learn how to use the auto-injector correctly.

After you inject epinephrine and your symptoms stabilize, go to an emergency room for treatment. Always get medical help to prevent another reaction.

How Do You Know If Know If You Have A Food Intolerance

The simplest way to know if you have a food intolerance is by looking for cues in your body. If you are intolerant to any food, your body is likely sending you clues and symptoms that you may not have been paying attention to.

Or things that are so strange that you would have never attributed them to being from a food.

There are so many things that we think of when we think of symptoms of dealing with food related issues, but there are some things that pop up that are so strange or so unexpected to be related to your diet that might surprise you.

One story I have of strange food intolerance symptoms, but not knowing how to identify what caused them is when I was gluten and dairy-free for about a year and a half. Even though I wasnt eating gluten or dairy, I was still having extreme brain fog and fatigue all the time.

Even though I felt a lot BETTER overall, I still felt like I needed to take a nap in the middle of the day. No matter how much exercise I had, the supplements I took, or the joy in my life I still wanted to just lay down and close my eyes sometimes for no real reason.

It got to be a big burden when I was driving or having a nice day out doing whatever couples with no kids do. I cant remember that anymore , but I do remember how much time we had to just have fun!

The results from this food sensitivity test came back, and I found out I was intolerant to eggs. Eggs!! Not gluten not dairy but EGGS!

How Do You Treat A Tree Nut Allergy

If your child has a mild reaction to a tree nut for the first time, such as itchy skin, Kim says its safe to stay home and watch them closely. If the reaction doesnt progress, you should make an appointment with your doctor as soon as possible. If the reaction involves more than mild symptoms, you should call 911.

At the hospital, your child may be treated with epinephrine, a life-saving drug that stops the reaction. Other drugs, such as antihistamines and steroids, may also be given. If your child is diagnosed with a tree nut allergy, you should always have an epinephrine auto-injector on hand and make sure everyone who is caring for your child knows how to use it. At the first sign of a serious reaction, you should call 911 and give the child the autoinjector.

If your child has mild symptoms that are not progressing but are bothersome, such as itchy, watery eyes and hives, you can give them a non-drowsy antihistamine. Kim says its important to wait at least 30 minutes to ensure that the reaction isnt escalating, as an antihistamine can mask the progression of symptoms.

How The Body Fights An Allergy

The brain and heart are the body’s rock stars when it comes to survival, but a functioning immune system is just as important. Our immune systems keep us healthy by warning us about dangerous substances that enter our bodies and can make us very sick. Viruses, bacteria and fungus lurk on every surface we touch and even on our own skin.

While they cause us little harm on the outside of our body, they can cause major damage if they get access to the inside. When there is a breach in our body’s security system and a foreign substance makes its way inside, our immune system recognizes that there is an intruder and heroically fights it off to prevent it from spreading throughout the body and causing illness.

To immediately treat anaphylaxis, doctors recommend that people with a nut or peanut allergy keep a shot of epinephrine with them. This kind of epinephrine injection comes in an easy-to-carry container. You and your parent can work out whether you carry this or someone at school keeps it on hand for you. You’ll also need to identify a person who will give you the shot.

You might want to have antihistamine medicine on hand too for mild reactions. If anaphylaxis is happening, this medicine is never a substitute for epinephrine. After getting an epinephrine shot, you need to go to the hospital or other medical facility, where they will keep an eye on you for at least 4 hours and make sure the reaction is under control and does not come back.

Food Intolerance Or Allergy

So, whats the difference between a food intolerance and a food allergy? According to WebMD, a food allergy is an immune system response. It occurs when the body mistakes an ingredient in food usually a protein as harmful and creates a defense system to fight it. Food allergy symptoms develop when the antibodies are battling the invading food. Milk is one of the eight most common food allergies.

A food intolerance on the other hand is a digestive system response rather than an immune system response. It occurs when something in a food irritates a persons digestive system or when a person is unable to properly digest or breakdown the food. Intolerance to lactose, which is found in milk and other dairy products, is the most common food intolerance.
