Smorgasbord Health Column – A – Z of Common Conditions – Allergies and Intolerances – #Christmas can be a challenge


As we approach the festive season, chances are that you are going to be eating more food that is outside your body’s comfort zone. Most of it will be sugary.. and the changes are there will be nuts. For someone who has diabetes, or a life-threatening allergy to certain foods, it takes the sparkle off the celebrations.

In this post I am going to take a look at the terms Allergy and Intolerance and explain the differences between the two. Many people will say that they have an allergy to certain foods for example but in fact they have an intolerance.

There are many symptoms and common ailments that are linked to food allergies and finding out what might be causing these is step one in resolving the problem naturally. Anxiety, arthritis, asthma, bronchitis, ME. Hayfever, Celiac disease, diabetes, headaches and eczema are just some of the diseases that could be linked to certain foods. Certainly long term intolerance or allergy to foods can contribute to more serious conditions such as Multiple Sclerosis and Cancer.

The first reaction that most people have is to totally discard the food responsible and never touch it again. Some people develop such a totally restricted diet that they do themselves harm by denying their bodies the nutrients that are essential to their health and well-being.

Some practitioners will also advise their clients to stop consuming certain foods and it is important that a client always ask when they can begin introducing these restricted foods again. If a reaction is very severe then yes of course it would be absolutely essential not to touch that food. Peanuts are a prime example. Nut allergies however are just that an allergy, which is very different from an intolerance and the two should not be confused.

What is an allergy? And what is the difference between an allergy and an intolerance

An allergic reaction is immediate. It is a fast response. An intolerance is by contrast a slow reaction. The speed with which an individual will react to certain stimulants is governed by two antibodies called IgE and IgG.

An allergy is an immediate reaction to a toxic substance either in food or in the environment that causes established and well-documented side effects. Our body is protected by anti-bodies one of which is called IgE. The role of this antibody is to forcibly reject toxins and in doing so the body undergoes some severe reactions in its effort to clean and heal its systems. Because IgE antibodies are intelligent, each fresh attack is worse than the last because it learns to produce a more effective and violent response. This is why what begins as a mild sneezing and coughing reaction may develop over repeated exposure to a more dangerous and life threatening reaction. Some of the intense reactions likely to be experienced are:

  • Intense itching on specific parts of all over the skin.
  • Hives (swollen red nodules just under the skin)
  • Swelling of the lips, tongue and throat.
  • Severe headache,
  • Nausea and vomiting.
  • Sneezing and coughing
  • Abdominal cramps
  • Diarrhoea

In severe cases this can lead to Anaphylactic shock which takes all of the above and leads to drop in blood pressure, extreme breathing difficulties, loss of consciousness and shock – all of which can be fatal.

What is an Intolerance?

An intolerance on the other hand is a build-up over time of the poisons in culprit foods, which cause the above symptoms in a mild or moderate form. In some cases it might only be intermittent and because it involves a build-up over a period of time it is very difficult to determine which food is the one causing the problem.

You might experience one or all of the above symptoms with differing severity and put it down to hay fever, or eating something that did not agree with you. You take an anti-histamine or a diarrhoea pill and the symptoms go away. A few weeks later you might suffer the same thing again but it is happening in isolation you do not connect to a common cause.

There is a different anti-body that seems to be involved in this type of delayed reaction and it is called IgG.

This antibody is more concerned with toxins that you have produced yourself rather than those that you have just ingested into your body. Its job is to rid the blood stream of toxins that have found their way into your system from the intestines. Because food in our digestive systems can take 24 hours to digest, the time taken for bacteria to get into the blood stream means a reaction might not take place for two to three days. Therefore difficult to pinpoint the problem food.

Apart from peanuts are there any other foods that might cause a severe reaction?

Everyone is individual and no one person reacts in the same way to any allergens but the most likely culprits for severe allergic reactions apart from nuts are peanuts (not a true nut) milk, eggs, soy, wheat and shellfish. All foods that most of us consider safe and extremely healthy. But if your chemical systems react to the chemicals in a food negatively, then these so called healthy foods can cause a severe reaction. Twenty percent of anaphylactic reactions appear to have no reason at all.

This type of allergy is likely to show up pretty quickly in childhood. There are some instances where a person’s chemical makeup has been changed through either drugs or treatments such as chemotherapy and they then begin to react to foods that they have eaten safely for years.

How do you treat an allergy of this severity?

In the first place avoidance of the food is essential. For example nut allergies are extremely difficult as many prepared products or meals eaten out may have some form of nut in them, which is not evident in the packaging or the menu description.

I have had a garden salad and found walnuts mixed in with it. Restaurants put other nuts on salads as a garnish. Despite new laws on labelling and food safety regulations, many menu items do not mention that it contains nuts and if you are not very careful you could inadvertently eat a piece without knowing.

Even more difficult is the use of crushed nuts in desserts – they are not even visible. It is much better than it used to be with food establishments and manufacturers legally obliged to label products and menu items carefully, however, if you are buying street food or even eating in a friend’s house you have to make sure to ask if it contains nuts or even nut oil.

What should you do immediately if someone goes into anaphylactic shock.

If someone is suffering from anaphylactic shock and you are on hand, you need to work very quickly. Usually the first signs may be reddened and swollen eyelids and wheezing. The person will look flushed and their ears will begin to swell.

Check to see if they are carrying adrenaline (Epi pen). It will usually be in the form of an injection kit. Most severe allergy sufferers, particularly those who have suffered anaphylaxis before will be carrying an injection on them and will also be wearing an ID bracelet. If they are unable to give themselves an injection, then you must do so. Straight into the muscle at the side of the thigh. That is the only place that a non-medical person should inject, as anywhere else could be dangerous. Adrenaline or epinephrine as it is also known, counters the intense reaction to the respiratory and cardiovascular systems. It constricts the blood vessels, relaxes the muscles in the lungs to improve breathing, reverses the swelling and stimulates the heartbeat.

If they are not carrying adrenaline you must get them medical attention urgently. Try and keep them calm. If the emergency service say that they cannot get to you within minutes then put the person in a car and get them to the nearest medical emergency room as fast as possible. As soon as you get there one person rush in and tell them you have an anaphylactic shock patient coming in so that they can come out to the car with you.

Knowing how to react is vital, as I found out  when I suffered two cases of anaphylactic shock. Once as a reaction to penicillin and once when I was attacked by fire ants in Texas. I was in full anaphylactic shock in minutes and luckily a neighbour drove us straight to the emergency room which was one block away. We arrived in bathing costumes and the driver dashed in and called for assistance. They were fast but it was still touch and go for about 20 minutes.

If you think that someone is going into this severe allergic reaction then act first and think later. Don’t wait to see if it develops, if breathing is beginning to be compromised then get help immediately.

Apart from food are there any other common causes fro this extreme reaction?

Quite a few people are allergic to latex which of course is found in rubber gloves and condoms. It mainly affects people who are in constant contact with latex products during medical procedures, like nurses and doctors. Patients who are in hospital for extended stays or have a lot of hands on medical treatment can develop an allergy.

There is a link to latex and food. It would seem that a person who reacts to latex might also react strongly to consuming bananas, avocados, kiwi, figs, peanuts, potatoes and tomatoes.

Other non-food allergens are bees, wasps and any other stinging insect such as the fire ants.

Are there less severe allergic reaction and what causes them?

Most of us at one time or another has suffered from a streaming nose, itchy eyes and some wheezing. It is an immediate reaction to contact with the allergen.

The top triggers are:

Inhalents (breathed in.)

Tree and plant pollens -Animal mites – House Dust mites – Mould spores -Tobacco smoke (contains over 4000 chemicals including banned pesticides and arsenic) -Car exhaust -Chemical products such as paint, dry cleaning solutions, perfumes and cosmetics)

Ingestants (taken by mouth)

Foods (dairy, eggs, peanuts, wheat, Soya, chocolate, tomatoes, corn, fish and shellfish) – Medications (antibiotics – tetanus) -Pesticides in food  – Heavy metals in tap water

Contactants (by touch)

Plants (poison ivy, oak) – Jewellery (nickel, copper) – Latex – Beauty products (hair dye, cosmetics)

Should people take anti-histamines and diarrhea pills to deal with the less severe symptoms?

To be honest as a nutritional therapist, I understand that the body is simply trying to rid itself of toxins but I am as guilty as anyone of reaching for the packet of pills to relieve the symptoms of colds, hay fever and stomach upsets.

Being realistic, once you have those types of symptoms, particularly streaming nose and eyes and a stomach upset, it is virtually impossible to get on with your daily life. Working, caring for young children even walking the dog have to be done, so of course you need help to get through that.

But, there is a cause for your allergic reactions. We have already established that a full-blown allergy is likely to be a fast reaction and you will be able to identify the problem food or product immediately.

Far more challenging is finding the culprit for intermittent but consistently mild to moderate reactions, that happen days or weeks apart. Or there may be only one symptom such as sneezing or wind, bloating or a rash.

What sort of symptoms might be present with sort of intolerance?

Apart from skin problems such as eczema and psoriasis, which tends to be chronic and long term, there could be hives that come and go in a week. Wind problems, bloating, indigestion, fluttering stomach, stomach upsets or constipation.

Next week I will be looking at a specific food allergy/intolerance to Milk and other dairy products.. and also one of the reasons that someone might be suffering from a food intolerance and it is to do with the gut.

Smorgasbord Letters from America 1985- 1987 – My Parent’s visit – Rennaisance Festival, Anniversary Party and nearly lights out!


Last week I shared the arrival and welcome party for my parents when they visited in the November of 1986…Yellow Roses and Stetsons

After the welcome party we had a day of relaxing before taking my parents to one of the spectacular events held every year in Texas. The Rennaisance Festival was started in the mid 1970s, on an abandoned strip mining site at Todd Mission about 50 miles Northwest of Houston. By the time we visited in 1985 with my parents, the festival had grown considerably, and was packed with great stalls selling crafts and food, as well as parades of street performers dressed in medieval costumes. Thankfully not an overly hot day and we did take plenty of opportunities to sample iced tea and delicious BBQ.

My father loved his food, and he made a beeline for the turkey drumsticks on one of the stalls, and despite evidence to the contrary… he is not being greedy, just holding David’s drumstick so he could take this candid shot. He does however look like the cat who got the cream, whilst my mother was trying to retain her ladylike demeanour whilst chomping down on this outsize snack!

It was quite a long day, and as I look at this photo, I realise that my parents at the time were only three and four years older than I am today! We enjoyed our time there, but unfortunately the rest of the photographs from the day, including the parade are somewhere safely packed away in the attic.

The rest of the week saw us pottering locally as David was away, but it gave Mollie and Eric a chance to relax, enjoy the pool and for my father to experiment with making his own Chi Chis…

We also were invited out to dinner at our friends Bill and Sylvia and my father definitely approved of Sylvia’s cooking.

It also gave me time to prepare for our 5th anniversary party on the Friday night. Most of our friends were coming with assorted courses organised between them. We had got into the habit of sharing the menu between us so that no one person was landed with either the cost or the labour, and it worked really well. It also offered us the opportunity to sample different dishes we might not cook ourselves. David arrived back on the Thursday and after a last shop for the starters we were providing, beer and wine we were ready to go.

I managed to get a quick shot of David and my parents before the guests arrived.

Because of the number of guests we had a menu that either involved a fork or a spoon and as you can see the place was packed with seats at a premium.

The complex was keen that people were not disturbed after 11pm, but after most of the guests had left and my parents had gone to bed, David and one of our friends decided to go for a run to clear their heads, whilst three of us opted to sweat it out in the hot tub in the recreation area just outside our block. Although November was a little nippy at night, it was pleasant enough sitting chatting on the side of the hot tub with our legs dangling in the water, whilst we waited for the others to return from their run.

Suddenly I felt movement over my thighs and up my back. I immediately reacted by jumping into the middle of the very hot water up to my waist which resulted in the most agonising stinging across my upper body. The reason for my panic was a severe allergic reaction to wasp and bees stings as a result of a childhood encounter with jellyfish.

When I was seven, and living in Malta, we kids used to swim at the naval station lido, jumping and diving off a wooden raft, attached to four oil drums for buoyancy. We could also dive under the raft and come up under the decking into an air gap between the drums.

Great fun until a swarm of jellyfish had the same idea. I got very badly stung and diving back and out into the clear water, I started swimming to shore screaming my head off. There was a hessian covered plank that was used to haul yourself out of the water and onto the rocky shoreline. Unfortunately, as I swung under the plank before hauling myself out, I met up with the rest of the jelly fish who were clinging underneath. My screams had alerted one of the naval fitness instructors who doubled as lido attendants. He came running with a first aid kit luckily, along with my mother, wondering what mischief I had got myself into this time.

This was long before the epi-pen(epinephrine) but I seem to remember being given an injection of adrenaline fairly quickly, which my mother told me saved my life.

Back to 1985, and within a few minutes, it was clear that I was going into anaphylactic shock and my friends with me recognised my attackers as fire ants and got me out of the tub and onto the path. My husband and other friend arrived back thankfully at that point. Nobody had mobile phones in those days and a rush up to an apartment to call an ambulance would take too long. We had also all been drinking, were dressed in either bathing costumes or running gear. Except for our friend Monty, who could not drink and despite being in his bathing costume, had his house and car keys on the side of the hot tub. His car was parked close by next to our block, and with David and the others holding me up, we piled into the car and we raced out of the complex onto the main road. Monty knew that there was an emergency centre about a mile away in one of the strip malls that was open 24 hours, but by the time we got there two minutes later, I was in a critical condition.

David tells me that one of our friends dashed in and returned with a gurney and doctors who raced me into resuscitation. This is where it gets a little weird, because I do clearly remember watching the activity from above, as they pumped me full of epinephrine and tried to keep me breathing.

Once I was in the clear, they wanted to keep me for a few hours to make sure that I would not have more problems. Our friends went home, and David stayed with me until I was discharged about 7.00 in the morning. Although not having any means of identification or credit cards they had treated me anyway, which I am eternally grateful for, and David returned later that day with details of our company health insurance.

My lower legs and back were not a pretty sight as the bites developed, and I felt incredibly sore and tired. We went home, and I went to bed and left David to explain to my parents what had happened,downplaying the details.

I had anti-histamines to take for a period of time, and it was recommended that I rest for several days. However, we were booked into the Marriott in San Antonio from Sunday to the Tuesday on a very special surprise for my father, which was to visit The Alamo. My parents knew that we had planned time away, but not where, and were all for cancelling the trip, but I was determined that a few fire ants were not going to ruin things. By Sunday morning I was still groggy, but I covered myself in calamine lotion, and took some pain killers and we headed off. I slept the entire 200 miles, except when we made a short stop for coffee, and then went straight to bed on arrival at the hotel. Thankfully by the next morning I was much improved, and eager to take my father on his adventure.

P.S. The exterminators were called in to deal with the large fire ant nest that they found under the decking of the hot tub on the Sunday morning, and there was an upside to my attack that night. That day, a children’s party was going to be held in the recreational area, and the kids would have been in and out of the tub for several hours and things could have got very much worse.

Next week – San Antonio, the Alamo and the Natural Bridge Caverns.
