What Is Food Intolerance

Can you develop allergies later in life?

A food intolerance isn’t the same as a food allergy.

People with food intolerance may have symptoms such as diarrhoea, bloating and stomach cramps. This may be caused by difficulties digesting certain substances, such as lactose. However, no allergic reaction takes place.

Important differences between a food allergy and a food intolerance include:

the symptoms of a food intolerance usually occur several hours after eating the food
you need to eat a larger amount of food to trigger an intolerance than an allergy
a food intolerance is never life threatening, unlike an allergy

Study Shows Adults Can Develop Food Allergiesthursday 24 August 2017

It’s often thought that if you have a food allergy, you’ll have it from childhood. But an American study has found that over half of people with food allergies develop them after the age of 18. What kind of allergies do adults get and is there a difference between them and childhood allergies?

Increase in food allergies

Food allergies in children are becoming more common and more severe. Research a few years ago revealed that almost 8% of children in the US had a food allergy with 40% of those children having a severe allergy. Two-thirds of children were found to have sensitivity to more than one type of food.

But what about adults? Can food allergies start in adulthood? According to a new US study, yes. It found that nearly 52% of Americans with food allergies develop them after the age of 18.

In addition, although children may grow out of their allergies , once an adult develops one, it usually remains with them for the rest of their life.

Shellfish the most common allergy

This new study estimated that 5% of adults in the US have a food allergy. This is based on a national survey conducted with over 40,000 adults.

The most common food allergy in adults according to the study is shellfish , followed by peanut allergy and tree nut allergies, including walnut, almond, cashew and brazil nuts .

Peanut allergy

A lot of research has been done into peanut allergy, particularly into finding a cure or treatment, as it can be so serious.

Types Of Food Allergies

Food allergies are divided into 3 types, depending on symptoms and when they occur.

IgE-mediated food allergy the most common type, triggered by the immune system producing an antibody called immunoglobulin E . Symptoms occur a few seconds or minutes after eating. There’s a greater risk of anaphylaxis with this type of allergy.
non-IgE-mediated food allergy these allergic reactions aren’t 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 .
mixed IgE and non-IgE-mediated food allergies some people may experience symptoms from both types.

Food Allergies In Older People Often Misdiagnosed

Peanut Allergy: Symptoms, Causes and Management Healthsoul

The most common allergen people develop as adults, according to the Northwestern Medicine study, is shellfish, affecting 7.2 million adults in the U.S. Other common adult-onset food allergies are to milk, peanuts, tree nuts, fin fish, eggs, wheat, soy and sesame.

Identifying a food allergy can be challenging in people 50 and older. The symptoms may not be as clear cut as when you’re younger and can involve the respiratory system, skin, nose, mouth, ears, gastrointestinal tract or even the heart.

It’s not uncommon for a health care professional to mistake food allergy symptoms in an older adult for problems with a medication, sleep issues, viruses, autoimmune diseases, general aging or gastrointestinal problems like irritable bowel syndrome. The longer a person continues to eat the allergen, the more serious the reactions can be, a particular concern in people with other health issues. Patients themselves may never consider a food allergy to be the root of their health issues, which can add to the difficulty in diagnosis.

Rhonda Adkins, of Great Falls, Mont., was stunned by her shellfish allergy diagnosis at 53. “The daughter of a shellfish fisherman, I literally grew up from age twelve eating shellfish almost five days a week, she says. We ate bay scallops like popcorn! When my allergist gave me information about shellfish allergies, I was surprised that it happens suddenly and in adults, typically in their fifties.”

Food Allergies In Children

No parent wants to see their child suffer. Since fatal and near-fatal food allergy reactions can occur at school or other places outside the home, parents of a child with food allergies need to make sure that their childs school has a written emergency action plan. The plan should provide instructions on preventing, recognizing and managing food allergies and should be available in the school and during activities such as sporting events and field trips. If your child has been prescribed an auto-injector, be sure that you and those responsible for supervising your child understand how to use it.

In November 2013, President Barack Obama signed into law the School Access to Emergency Epinephrine Act , which encourages states to adopt laws requiring schools to have epinephrine auto-injectors on hand. As of late 2014, dozens of states had passed laws that either require schools to have a supply of epinephrine auto-injectors for general use or allow school districts the option of providing a supply of epinephrine. Many of these laws are new, and it is uncertain how well they are being implemented. As a result, ACAAI still recommends that providers caring for food-allergic children in states with such laws maintain at least two units of epinephrine per allergic child attending the school.

How Do Allergies Develop Later In Life

Allergies can affect anyone, regardless of age or gender. Allergic reactions may come back after many years of remission or be new altogether.

Environmental pollutants, hormones, stress, smoke, perfume, or chemicals may play a role in the development of allergies later in life. They can also impact the severity of the symptoms. Several decades ago, these synthetic chemicals were not available. Today, we expose ourselves to hundreds of them daily.

According to Mayo Clinic experts, the exact reason some people develop allergies later in life is unknown. A common instance of allergy development later in life is when a person moves from one geographical location to another. Exposing yourself to new plants and pollens can trigger underlying allergies.

Food Allergy Or Intolerance

A food allergy is an abnormal and overactive response from your immune system to something that it shouldnt react to.

When you eator sometimes even come into contact withthe offending ingredient, your immune system revs up production of antibodies: proteins that fight foreign substances. These indirectly trigger the production of histamines, which start what we recognize as an allergic reaction. This whole cascade happens quickly, usually within minutes.

Allergy symptoms can involve your skin, respiratory system, and gastrointestinal system. They may be mildly uncomfortable or downright dangerous, and can vary in severity and type each time you come into contact with the food.

Swelling, itching, hives, shortness of breath, difficulty swallowing, lightheadedness, and/or vomiting within a few minutes to a couple of hours of eating a food may signal an allergy. If you have such symptoms after a meal, see your physician or an allergist, Ogbogu saysafter seeking emergency care, if needed.

This is especially crucial if you have a reaction after eating shellfish. Its rare to develop an anaphylactic allergy to most foods as an adult, but shellfish is the exception, says Manish Ramesh, M.D., Ph.D., director of the Food Allergy Center at Montefiore Medical Center in the Bronx and Scarsdale, N.Y.

Among adults, shellfish is the most prevalent food allergy, but milk, eggs, soy, peanuts, and tree nuts are also common offenders.

The Causes Of Food Allergies

There are many different causes of food allergies, but the most common are hereditary factors, medical conditions, and medications.

Hereditary factors: If you have a family history of allergies, you are more likely to develop them yourself. This is because allergies are often passed down from generation to generation.

Medical conditions: If you have a medical condition that affects your immune system, you may be more likely to develop allergies. For example, people with autoimmune disorders or HIV/AIDS are at an increased risk for developing allergies.

Medications: Some medications can cause allergies. For example, people who take antibiotics or certain types of cancer treatments may be more likely to develop an allergy to a food that they otherwise would not have been allergic to.

Living With A Food Allergy

What Causes Food Allergies?

The only way to manage a food allergy is to avoid the allergen. Sounds simple, right? Actually, living with a food allergy can be complicated and challenging. Your allergen could be an ingredient in foods you would never imagine finding it in.

“Even after I had my first reaction to shrimp, I was taking chondroitin and krill oil. No wonder I was still getting mild random hives, Adkins says. Chondroitin, a supplement people take for joint pain and osteoarthritis, contains glucosamine, which is made of shellfish.

Eating out requires careful thought and questioning. “When going to dinner you have to tell people they just don’t think to ask, Adkins says. You have to think about the salt and pepper shakers in seafood restaurants. People handle them with fishy hands. Many Asian condiments have shellfish. Buffets are a nightmare.”

Here are some helpful tips for managing your food allergy:

Read the ingredient list on all foods.
Avoid cross-contamination if others in your home continue to eat the allergen. Don’t share the same unwashed cutting board, for example.
Be clear with restaurant staff and verify that they can prepare your food allergen-free.
Alert family and friends so food you consume from them is allergen-free.
Don’t cheat! Even one bite of your allergen can be life-threatening.
