Food Allergy Rash Vs Food Intolerance
A food allergy occurs when your immune system adversely reacts to proteins in a certain food youre allergic to. This is not the same thing as a food intolerance.
Food intolerance is primarily a digestive issue that can cause symptoms similar to food allergies, except that its not life-threatening.
Non-itchy rashes from a food intolerance can also develop over time, such as chicken skin on arms. This is unlike a food allergy rash, which tends to occur within minutes or hours of eating the suspected food. Food intolerance can also cause bloating, stomach pain, and mild digestive upset.
Another key difference is that you can sometimes have small amounts of a food without a problem if you have an intolerance. With an allergy, even a small amount of the food can cause issues.
According to the AAAAI, most suspected cases of food allergies are actually intolerances. However, you dont want to take a chance with self-diagnosis. An allergist can help you determine the difference.
Learning About Food Allergies
What Increases Your Risk
You have a greater chance of developing food allergies if you:
- Have a family history of allergy. If both of your parents have allergies, you are more likely to have allergies.
- Have another allergic condition such as atopic dermatitis or asthma.
- Are young. Infants and children have more food allergies than adults.
- Have a medical condition that makes it easier for allergens to pass through the walls of the stomach and intestines and enter the bloodstream. These conditions include gastrointestinal disease, malnutrition, prematurity, and diseases that , such as eosinophilic esophagitis .
You have a greater risk for a life-threatening allergic reaction from food allergy if you:
- Have asthma.
- Develop allergy symptoms within minutes of eating the food.
If you or your child has a severe food allergy, always carry epinephrine and know how to use it. You should also wear a medical alert bracelet at all times. Being prepared to immediately deal with a severe allergic reaction reduces the risk of death.

Myth No : You Only Need A Blood Test To Diagnose A Food Allergy
Blood tests can sometimes be misleading. They may have a result called a “false positive.” In other words, it says you’re allergic when you’re really not. How often does that happen? A whopping 50% to 75% of the time, McMorris says.
To get a clear diagnosis, an allergist may do something called a “food challenge.” They’ll give you small doses of a food and watch you to see if you get an allergic reaction. If there are no symptoms, they’ll gradually increase the amount. Still no signs of trouble? You’re declared allergy-free.
“Food challenges can confirm that somebody actually has a food allergy,” McMorris says. “They’re also used to see if someone has outgrown a food allergy.”

When Should You Call Your Doctor
Give an epinephrine shot if:
- You think you are having a severe allergic reaction.
- You have symptoms in more than one body area, such as mild nausea and an itchy mouth.
After giving an epinephrine shot, call 911, even if you feel better.
911 if you have:
- Rapid swelling of the throat or tongue.
- Trouble breathing, are wheezing, or have a deep cough, a pale face, or blue lips or earlobes.
- Signs of shock, including:
- Lightheadedness or a feeling that you are about to pass out.
- Restlessness, confusion, or a sense of impending doom.
- Moist, cool skin, or heavy sweating.
- Weakness, thirst, nausea, or vomiting.
If you see someone having a severe allergic reaction and the person becomes unconscious, 911 or other emergency services immediately.
If your food allergy symptoms are getting worse, call your doctor. It’s important to know which foods are to blame so that you can avoid them.
What Is Histamine Toxicity Is It A Type Of Food Allergy
There are many conditions that can mimic food allergy. It is critical to distinguish true food allergy from other abnormal responses to food, that is, from food intolerance, which can occur in a variety of other illnesses or food poisoning, which occurs when contaminated food is ingested. If a patient says to the doctor, “I think I have a food allergy,” the doctor has to consider a number of diagnoses.
The possibilities include not only food allergy but also any other diseases that have symptoms brought on by food. These include reactions to certain chemicals in food for example, histamine or food additives, food poisoning, several other gastrointestinal diseases, and psychological symptoms.

What Causes Food Allergies
In those with food allergies, the immune system treats a specific protein in a food as a harmful substance that may cause disease. It responds by producing IgE antibodies that will play a role in attacking this protein.
When the person eats the same food again, the antibodies are ready, so the immune system reacts immediately by releasing histamine and other chemical substances into the bloodstream. These chemicals cause the symptoms of food allergies.
Histamine causes blood vessels to expand and the skin to become inflamed or swollen. It also affects the nerves, making the skin feel itchy. The nose may produce more mucus, resulting in itching, burning, and a streaming nose.
Why Do Some People Make Ige Antibodies To A Food And Do Not Have An Allergy To The Food
There are many other immune system factors that enable IgE antibodies to trigger an allergic reaction. Some people make IgE antibodies to food but their immune system does not make the factors to allow an allergic reaction to happen. People who make an IgE antibody but tolerate the food are not allergic to it. They are said to be only sensitized to it. Note that even though the words sound the same, being sensitized to a food is not the same as having a food sensitivity.

Scared To Eat: Conquering Anxiety Around Food Allergies
Eating brings pleasure, energy, and well-being to our lives. A disruption of this simple, often mindless, but important activity could lead to stress and anxiety.
People who have food allergies have to be extra careful about what they eat. A simple ingredient such as eggs or nuts could ruin a meal by causing hives or wheezing, and, in extreme cases, cause a reaction so severe that an epinephrine injection is needed to save the person from a life-threatening condition.
Food intolerances, or adverse reactions to specific foods, can also cause harm to a person, but generally lead to minor symptoms such as diarrhea or stomach cramps, according to the National Center for Biotechnology Information website. Celiac disease, for example, is not a food allergy but rather an autoimmune issue. People with celiac disease who eat gluten experience health problems as a result.
Elika Kormeili, a therapist specializing in food-allergy issues and founder of the Center for Healthy and Happy Living, says that she has suffered from food allergies and knows the stress and anxiety they can cause. She says certain social situations that involve food, such as birthday celebrations or work lunches, can be so stressful that people with food allergies might avoid them entirely.
She has the following tips for coping with food allergies and the anxiety that sometimes follows:
When To Seek Medical Advice
If you think you or your child may have a food allergy, it’s very important to ask for a professional diagnosis from your GP. They can then refer you to an allergy clinic if appropriate.
Many parents mistakenly;assume their child;has a food allergy when their symptoms are actually;caused by;a completely different;condition.
Commercial allergy testing kits are available, but using them isn’t recommended. Many kits are based on unsound scientific principles. Even if they are reliable, you should have the results looked at by a health professional.

Are Food Poisoning And Food Allergies The Same Condition Is Lactose Deficiency A Food Allergy
- Food poisoning: Eating food that is contaminated with microorganisms, such as bacteria, and their products, such as toxins, is the usual cause of food poisoning. Thus, the ingestion of contaminated eggs, salad, milk, or meat can produce symptoms that mimic food allergy. Common microbes that can cause food poisoning include the noroviruses, Campylobacter jejuni, Salmonella, Listeria monocytogenes, Vibrio vulnificus, and E. coli0157:H7.
- Lactase deficiency : Another cause of food intolerance, which often is confused with a food allergy, specifically to milk, is lactase deficiency.
- This common food intolerance affects at least one out of 10 people.
- Lactase is an enzyme in the lining of the small intestine. This enzyme digests or breaks down lactose, a complex sugar in milk, to simple sugars, which are then absorbed into the blood.
- If a person has lactase deficiency, he does not have enough lactase to digest the lactose in most milk products. Instead, other bacteria in the intestine use the undigested lactose, thereby producing gas.
- Symptoms of lactose intolerance include bloating, abdominal pain, and diarrhea.
- In a diagnostic test for lactase deficiency, the patient ingests a specific amount of lactose.
- Then, by analyzing a blood sample for simple sugars, the doctor determines the patient’s ability to digest the lactose and absorb the simple sugars.
- A lower than normal value usually means a lactase deficiency.

Whats Changed Why Do So Many Kids Now Have Food Allergies
When reading about food allergies, many researchers refer to it as an epidemic. The increase in cases over the past couple of decades has been dramatic.
What has changed? That is a hard question to answer because many things have changed in our environment over the past 30+ years.
From antibiotic use to changes in food production, food additives, household chemicals, plastics, childhood vaccination schedules, sunscreen use, less fiber in the diet the list of possible reasons for an increase in allergies is long.
This long list of changes makes it is easy to come up with a hypothesis that fits a viewpointand you will often see on alternative health sites information on allergies to fit an agenda.
Here is one such hypothesis, which may very well be influenced by my own viewpoint:
Q Are Some Food Allergies More Deadly Than Others
A.;Any food can cause a severe reaction. However, peanuts, tree nuts and cows milk tend to cause the most life-threatening reaction, anaphylaxis.
Anaphylaxis is an acute reaction in which the throat and airways close and blood pressure plummets as the body releases an antibody intended to eject the unwelcome invader.
The FDA estimates such extreme allergic reactions lead to 30,000 emergency room visits, 2,000 hospitalizations and 150 deaths every year.
An allergist can check you for both food and airborne allergies.

Detailed Health History And Physical Exam
The health history and physical exam determines how likely a food allergy is the cause of a personâs symptoms after eating a food. The history also helps to identify which foods should be suspected. It is the most important step to a diagnosis because it helps to determine which foods to test, if any. Sometimes, the health history and physical exam will show that food allergy tests are not needed.
Are There Other Recommended Tests To Help Diagnose Food Allergy
Food elimination diets remove a group of foods from the diet on a trial basis to see if this stops the signs and symptoms of allergic reactions.
Food elimination diets can be tempting to try. They can be hard to follow and are rarely needed for a diagnosis. Elimination diets that restrict a lot of foods can also lead to malnutrition, especially in children. If a child with a higher risk of developing food allergy avoids a tolerated food for a long time, it may increase their risk of developing an allergy to that food.
An allergist can tell you whether an elimination diet would be helpful. They can provide a list of foods to stop eating for a specific trial period based on the personâs health history and test results. A registered dietitian can provide advice and guidance to help the person meet their nutrition needs and support meal planning for the trial. Whether and how each food should be added back to the diet should be discussed with the allergist. Some foods should only be reintroduced in a medical clinic during an oral food challenge.

Awareness: The Main Food Allergy Cure
When you become aware of these negative habits of behavior, you suddenly also have the ability to change them.
Awareness = Control
When you become aware, you gain your power back.
This week, pay special attention to whats happening in your life real time or just before you notice food allergy symptoms and specifically, digestive upset.
For most people, digestive problems usually show up pretty quickly, so the trigger is probably something that is either happening while you eat or shortly before. Or it could be an ongoing stressor that is more chronic. In other words, you may have low level stress running in the background all the time that has added up, taking your body to its breaking point.
Should I Wait To Offer Common Food Allergens To My Baby For The First Time
- It isnt recommended that you delay introducing a food beyond 6 months of age to try to prevent an allergy.
- For children considered at high risk of developing an allergy , consider introducing common food allergens at around 6 months of age, but not before 4 months.
- Once you offer these foods to your child, its important to continue to offer them on a regular basis.
- When introducing foods that are common food allergens, try offering no more than 1 per day. Wait 2 days before you introduce another. This makes it easier to identify a food that may have caused a reaction.
- If you have concerns, speak to your health care provider.
