Doctors Are Learning The Connection With Eczema And Allergies
Researchers are still working to discover how food allergies cause eczema and how eczema might actually lead to food allergies. It is commonly believed that eczema can be an immune response to an allergen. However, in some cases, it may create opportunities for additional reactions to other substances.
Eczema damages the skin. The structures of the cells start to collapse because of inflammation and itching. The cells break down and flake off, leaving the skin red and sensitive. During this time, the skin is unable to do its job protect the body from outside threats. As a result, more irritants can come in contact with the body and create allergic reactions.
Some researchers have found that there is a connection between kitchen workers with eczema and food allergies. The risk of developing food allergies is higher for people with eczema who work in kitchens compared to those with eczema in other professions. This is because kitchen workers are exposed to potential allergens throughout their shifts.
For example, even if you did not have a food allergy when you began working at a seafood restaurant, you may develop one over time because of your eczema. Your inflamed skin is unable to protect you from the constant exposure to crustacean particles in the air.
This creates a cause-and-effect conundrum for researchers. Is eczema the result of a food allergy or does it lead to food allergies? Both situations are possible.
How Eczema Scratching Can Cause Food Allergies
The weirdest way in which eczema itching causes food allergies is the act of scratching.
New research, so far only done in mice, at Boston Childrens Hospital showed that scratching the skin increases the chance of allergic reactions to foods, including anaphylaxis. The study showed that when you injure your skin by scratching, the immune system releases certain immune cells in the small intestine. Putting so many unnecessary immune cells in the small intestine can cause them to overreact to any food proteins that are undigested, leading to a food allergy.
The Sun Sweat And Sunscreen
You can be out in the sun, but your skin may not like getting hot and sweaty. If so, stay cool and seek out shade. Always wear sunscreen. Sunburns inflame your skin and can lead to an eczema flare. If youre sensitive to sunscreens, block out burning rays with mineral versions, like zinc oxide or titanium dioxide. Sunscreens made for the face may also give you gentle protection.

How Are Food Allergies Treated
A child who has a food allergy should always have two epinephrine auto-injectors nearby in case of a severe reaction. An epinephrine auto-injector is a prescription medicine that comes in a small, easy-to-carry container. Its easy to use. Your doctor will show you how. Always have two auto injectors nearby in case one doesnt work or your child needs a second dose.
The doctor can also give you an allergy action plan, which helps you prepare for, recognize, and treat an allergic reaction. Share the plan with anyone else who needs to know, such as relatives, school officials, and coaches. Wherever your child is, caregivers should always know where the epinephrine is, have easy access to it, and know how to give the shot. Also consider having your child wearing a medical alert bracelet.
Time matters in an allergic reaction. If your child starts having serious allergic symptoms, like trouble breathing or throat tightness, use the epinephrine auto-injector right away. Also use it right away if symptoms involve two different parts of the body, like hives with vomiting. Then call 911 and have them take your child to the emergency room. Medical supervision is important because even if the worst seems to have passed, a second wave of serious symptoms can happen.

How Can I Reduce My Risk Of Eczema
There are steps you can take that may prevent eczema outbreaks:
- Establish a skin care routine, and follow your healthcare professionals recommendations for keeping your skin healthy.
- Wear gloves for jobs where you have to put your hands in water. Wear cotton gloves under plastic gloves to absorb sweat, and wear gloves outside, especially during the winter months.

How Common Are Secondary Allergies
Not much is known about secondary allergies and OAS especially in adult development. The first thing to know is that anyone can develop an allergy during their lifetime. While many parents discover allergic reactions in their kids when they try foods for the first time, adults can also form allergies to substances that have been around for years. Your eyes might suddenly start to water any time you are around a dog or your tongue could become itchy and swollen when you eat pineapple.
I have seen patients of all ages who have developed eczema secondary to food allergens at various stages in their lives even though they dont have an Asthma or Allergies. This may be due to developing a hypersensitivity at a certain age in their lives to milk protein, corn or other edible proteins, says Dr. Praveen Buddiga.
Because allergies can form at any time, and because many go unreported, its hard to track how common primary allergies are. This means tracking secondary allergies is even more difficult, as doctors need to be aware of the primary allergies while having the ability to make a connection to the secondary ones. Oftentimes, doctors will just label two allergens as primary irritants, rather than finding the cause and effect from one to another.
How To Prevent Eczema From The Inside Out
Here are two ways to treat your eczema naturally:
12-week low chemical diet
The Eczema Detox is a healthy low chemical diet that is low in sugar and totally free of glutamates/MSG, preservatives/additives and dairy. It also has plenty of gluten-free and vegan options.
The Eczema Detox, which was published in 2018 and is the new version of The Eczema Diet, also shows you how to successfully diagnose food intolerances and chemical intolerances , so you know what to avoid and what to eat to become eczema free.
Skin friendly supplements
There are a range of nutrients to help prevent chemical sensitivity and repair eczema-prone skin, including magnesium, molybdenum, zinc, biotin, vitamin B6 and a range of vitamins to deactivate salicylates and other itch-promoting chemicals. Molybdenum deactivates sulphite preservatives and amines anti-histamine vitamin C and vitamin B6 to help reduce allergic reactions .
But its also what you avoid that can make a difference Supplements usually contain hidden additives that can cause adverse reactions if you are a sensitive type of person that is prone to eczema.
Skin Friend AM is the supplement I created to prevent my daughters eczema more than fifteen years ago. It took years of testing before I felt confident that it could help others, and I worked with hundreds of eczema patients who tried the product and provided feedback for years before this product was manufactured in bulk and sold online.

What Are Food Allergies
Food allergies are inappropriate immune responses to foods. Different types of food allergies cause different types of symptoms. The symptoms are typically determined by whether mast cells and IgE play a role in the food allergy. Food allergies can be characterized by whether IgE is involved:
- IgE-Mediated Food Allergy
- Mixed IgE- and Non-IgE-Mediated Food Allergy
The Connection Between Hives And Allergies
Hives can result from an allergic reaction, temperature extremes, infections, stress, and certain illnesses. In rare cases, hives may be accompanied by angioedema. Angioedema can be a life-threatening condition characterized by swelling around your throat, feet, hands, and lips and requires immediate medical attention.
Generally, hives are linked with allergens that trigger an acute skin flare-up within minutes. Some common hive producing allergens include:
- Foods, particularly tree nuts, peanuts, shellfish, fruit, and milk
- Allergy shots and other medicines
- Insect stings and bites
However, in some cases, a hive breakout may not be linked with common allergens at all. These include:
- Contact with certain substances
- Exposure to snow or cold water
- Friction or pressure on particular skin areas, sitting in the same position for too long, etc.
Hives that result from stimuli or physical causes are referred to as physical hives. Discovering the exact cause of chronic hives is difficult. Sometimes, chronic hives are linked to an underlying autoimmune condition. Other times food, medicines, infections, or insects can trigger a flare-up. Although there are many triggers for acute hives, chronic hives appear to be related more to an autoimmune issue within a persons body.

Ask The Allergist: The Food Allergy
Q: What is the link between food allergies and eczema , especially in young children? How is it determined if a food allergen is contributing to eczema?
Allison Ramsey, MD: Eczema, or atopic dermatitis, is a common rash that presents early in infancy and its closely associated with food allergies. We know infants and toddler with eczema have a much higher rate of sensitization, meaning a positive skin test or positive blood work to food.
Up to 30% of eczema patients will develop an immediate reaction to a food, meaning when theyre exposed to the food allergen, they will develop symptoms such as hives, itching, respiratory symptoms and/or gastrointestinal symptoms. The foods that cause skin reactions are the most common food allergens, including milk, egg, soy, peanut, tree nuts, wheat, fish and shellfish, and sesame.
Board-certified allergists are able to perform skin testing, blood tests or oral food challenges to determine whether a food is linked with eczema symptoms.
Sometimes food allergens can contribute to poor eczema control over time, especially in severe cases. For example, if a child consumes milk every day and milk is an allergen, this can lead to poor eczema control.
Allergists tend to err on the side of keeping the diet broad, but when chronic exposure to a specific food allergen leads to poor eczema control, sometimes eliminating that food from the diet can lead to skin improvement.
Topical Application Of Edible Oils
Sometimes certain foods can be beneficial not as foods, but when used as topical treatments for eczema. The National Eczema Foundation suggests using virgin/cold pressed coconut oil on your skin to limit the staph bacteria on your skin, cutting the risk of an infection. Simply apply the oil to damp skin for best results. Another edible oil, sunflower oil, can also help the skin due to its anti-inflammatory properties. As with coconut oil, be sure youre using a pure form of the oil thats additive-free. Both oils can help retain the moisture in your skin by acting as a natural barrier between the air and your skin. This reduces dryness and helps cut the itchy feeling so typical of eczema. You can safely use these oils twice a day, but only if you arent allergic to them.10

How Is It Caused
ACD is a delayed hypersensitivity reaction. In ACD, a persons immune response is induced by a particular sensitising substance, known as a contact allergen in this case, an acrylate monomer. The first phase is called sensitisation, or induction. At this stage the person becomes immunologically sensitised although they show no symptoms. When the person is re-exposed to the same substance, or something that reacts with it, this triggers the next phase: elicitation. This activates an individuals immune system and symptoms become apparent.
The appearance of ACD will depend on which area is affected. Unsurprisingly, ACD to acrylates is most commonly seen on the fingertips and nails.
Symptoms can include:
- NAIL DYSTROPHY distortion and discoloration of normal nail-plate structure
- ONYCHOLYSIS loosening or separation of a fingernail or toenail from its nail bed. This usually starts at the tip of the nail and progresses back
- HYPERKERATOSIS thickening of the nail
- FISSURING and SPLITTING of the fingertips and inflammation of the nail fold.
Symptoms may be found not only around the nail area but also in areas that are commonly touched, such as the eyelids, mouth, chin and sides of the neck. However, uncured acrylate monomers can cause symptoms anywhere on the body that they touch. Symptoms include patches of streaky, red, tight, dry and itchy skin, characteristic of eczema. Diffuse eyelid eczema is also often seen in ACD to nail enamels and removers.
Foods That May Cause Allergic Reactions
When it comes to food allergies, peanuts, wheat, eggs, cows milk, soy and shellfish are among the most common culprits. The itchiness caused by these foods and subsequent scratching can then lead to flare-ups or worsening of dermatitis symptoms.
Here are four examples of foods that you may not have realised can cause skin problems:

What Is The Best Treatment For Food Allergies
If you experience 2 or more symptoms and you have been prescribed an epinephrine injector take it and get to the doctor. Dont wait until its too late its better to be safe than sorry. If you dont have an epinephrine injector, still get to the doctor, take an antihistamine like Benadryl if you have it.
Ask your doctor to give you a demonstration on how to use an injector if they havent already and you can read more about how to use the injector on the epi pen website.
The best treatment for food allergies is avoidance. The only thing that will ensure you will not have a reaction to a specific food is not to eat or come in contact with it. Treatments for food allergies are still changing. As time progresses doctors have worked on promising techniques to get rid of an allergy. However, there is no guaranteed treatment to get rid of food allergies yet.

Research Into Foods That May Help Eczema
Most of the foods and supplements that scientists have studied havenât shown much promise for eczema relief, but research is ongoing.
For example, some studies say that probiotics, a type of live bacteria you can get in yogurt or supplements, may help relieve the symptoms of the condition in children. Most of these studies happened in other countries and tested different kinds of probiotics. So it’s not clear what types are most useful.
Scientists are studying tea, as well. Although there’s no clear evidence, a few studies suggest that drinking black, green, or oolong tea may help relieve symptoms. Researchers are also looking at omega-3 fatty acids found in fish and fish oil, which help fight inflammation, as a way to help eczema.

Food Allergies And Eczema
What percentage of Americans believe they have food allergies? Its been going up rapidly. A study done several years ago found that about 25 percent of people in this country believe they have food allergies, and Ive got to think its 30 to 35 percent today. It has almost become a fad.
What percentage of Americans actually have food allergies? Somewhere between 2 and 5 percent of the population. A lot of people believe they have food allergies but they dont.
Why is that? The media has sensationalized food allergies, and theyre an easy thing to blame. I also think that more and more people are looking for answers to many conditions that dont already have answers, and they are getting tested for allergies. I see a lot of kids coming in with attention decit disorder or autism, and their parents have a strong belief that theyre eating something that theyre allergic to thats contributing to their condition.
Sometimes allergists are doing tests for foods in a situation where foods are unlikely to be causing the condition. More often a doctor, a primary care doctor, a naturopath or a chiropractor says, Hey, lets run a panel of food tests and see what comes up. And this leads to a lot of people being told they have allergies.
