Food intolerance – Is it a food intolerance or food allergy?

Is it a food intolerance or food allergy?

Is it a food intolerance or food allergy?

A food intolerance is difficulty digesting certain foods and having an unpleasant physical reaction to them

It causes symptoms, such as bloating and stomach pain, which usually come on a few hours after consuming the food.

The number of people who believe they have a food intolerance has risen dramatically over recent years, but it’s hard to know how many people are truly affected. Many people assume they have a food intolerance when the true cause of their symptoms is something else.

 

What are the symptoms of food intolerance?

In general, people who have a food intolerance tend to experience:

tummy pain, bloating, wind and/or diarrhoea, or

skin rashes and itching

These symptoms usually come on a few hours after eating the food.

It can be difficult to know for sure whether you have a food intolerance as these are very general symptoms, typical of many other conditions too.

Is there a food intolerance test?

There are no tests for food intolerances. The only way to know if you have one is to monitor your symptoms and the food you eat. See what happens when you cut out the suspected food for a while, and then reintroduce it back into your diet.

Food diary

Try keeping a food diary, noting:

what foods you eat

any symptoms you have after eating these foods

when these symptoms come on

Trial elimination diet

Once you have a good idea which foods may be causing your symptoms, you can try excluding them from your diet one at a time and observing the effect this has.

Try:

Cutting out the suspected food from your diet for two to six weeks and see if your symptoms improve.

Then, reintroduce the food, to see if symptoms return. You may find you can tolerate a certain level, and you only get symptoms if you have more than this amount.

Consider seeing a dietitian to make sure you’re receiving all your recommended daily nutrients while you do this trial. Find a registered dietitian.

Never restrict your child’s diet unless this has been advised by a dietitian or your doctor.

Could my symptoms be something else?

If you regularly have diarrhoea, bloating, tummy pain or skin rashes but you’re not certain of the cause, see your GP.

Your GP may be able to diagnose the cause from your symptoms and medical history. If necessary, they’ll carry out tests, such as blood tests.

You can also do some research yourself. It may help to read up on other conditions that cause similar symptoms. For example, learn about:

irritable bowel syndrome

stress and anxiety disorder

lactose intolerance

coeliac disease

inflammatory bowel disease

food allergy (and read ‘Is it a food intolerance or food allergy?‘ below)

Bowels are sensitive organs, and it’s common to have bowel symptoms when you have been ill or feel run down or stressed.

Is it a food intolerance or food allergy?

A food intolerance is not the same as a food allergy. Here’s how you can tell the difference:

A food allergy:

is a reaction from your immune system (your body’s defence against infection) – your immune system mistakenly treats proteins found in food as a threat

can trigger typical allergy symptoms, such as a rash, wheezing and itching, after eating just a small amount of the food (these symptoms usually come on rapidly)

is often to particular foods – common food allergies in adults are to fish and shellfish and nuts, and in children to milk and eggs as well as to peanuts, other nuts and fish

can be serious

A food intolerance:

doesn’t involve your immune system – there is no allergic reaction, and it is never life-threatening

causes symptoms that come on more slowly, often many hours after eating the problem food

only results in symptoms if you eat reasonable amounts of the food (unlike an allergy, where just traces can trigger a reaction)

can be caused by many different foods

Read about the diagnosis of food allergies.

What causes a food intolerance?

It is often unclear why a person is sensitive to certain foods.

If your symptoms come on after having dairy products, it’s possible you may have lactose intolerance. This means your body can’t digest lactose, a sugar found in milk, yoghurts and soft cheeses. Your GP can usually diagnose lactose intolerance by looking at your symptoms and medical history.

Some people have trouble digesting wheat and experience bloating, wind, diarrhoea, vomiting and stomach pain after eating bread. Read more about wheat intolerance (also known as wheat sensitivity).

Otherwise, the culprit may be a food additive, chemical or contaminant, such as:

monosodium glutamate (MSG)

caffeine

alcohol

artificial sweeteners

histamine (found in Quorn, mushrooms, pickled and cured foods, and alcoholic drinks)

toxins, viruses, bacteria or parasites that have contaminated food

artificial food colours, preservatives or flavour enhancers

Gluten intolerance

Many people cut gluten from their diet thinking that they are intolerant to it, because they have symptoms that come on after eating wheat.

But it’s hard to know whether these symptoms are because of a genuine intolerance to gluten, an intolerance to something else in wheat, or nothing to do with wheat at all. It may help to read Should you cut bread from your diet?

In reality very few people need to cut out gluten from their diet, although it’s important to do so if you have coeliac disease (which is neither an intolerance nor an allergy).

How do I manage it?

If you’re confident you are intolerant to a particular food, the only way you can manage this is to:

stop eating the food for a while, and then

reintroduce small quantities while monitoring how much you can eat without symptoms coming on

By checking food labels, you’ll learn which sorts of foods to avoid.

If you think your child may have a food intolerance, check with your GP or a dietitian before eliminating foods from their diet, as a restricted diet could affect their growth and development. Cows’ milk, for example, is an important source of calcium, vitamin D and protein.

When do I need to see a specialist?

Your GP may want to refer you to a specialist if they’re not sure what’s causing your symptoms and further tests are needed.

You may also be referred if your child has digestive symptoms (such as tummy pain and diarrhoea) and:

isn’t growing well

hasn’t responded to any elimination diet that your healthcare professional recommended

has reacted suddenly or severely to a food

has a suspected food allergy

Food Allergies vs Food Intolerance

Over the last few years there has been a lot of ink spilt over the differences between
Food Allergies and Food Intolerance.

This infographic from our freiends as Yorktest should help to clear up a few of the common misunderstandings.

Millions of us cutting out everything from gluten and dairy to sugar and fat….but how many of us really need to?

Millions of us are cutting out different foods and ingredients from our diets, without any medical guidance to do so.

That’s according to new research released today which shows that almost one in ten have eliminated dairy from their diet – half of those based on their own self-diagnosis, slightly less wheat – more than 40% having self-diaganosed an intolerance, and a similar number gluten – with half of those having made the decision based on their own knowledge.

Furthermore, following the war on sugar in the last two years, one in five of us have eliminated it from our diets, while one in six have ditched fat.

The study by Nutricentre also asked respondents what other measures they have taken to improve their health and or lose weight in the last two years, with a third having tried eating smaller portions, one in six skipping meals and a similar number skipping breakfast.

More than one in 20 have gone on a juice diet, while slightly less have tried weight management classes and soup diets, with some having gone vegetarian and some vegan.

But do these measures actually work? And what do you need to know if you are set on cutting out certain foods in 2016?


Recent research suggests:-

• As many of us continue on with our new year health kicks, a new study released today looks at the trend for eliminating food groups from our diets as a fix-all solution to weight and health issues

• Almost one out of ten say they have cut out dairy in the last two years, with similar numbers having eliminated gluten and wheat

• More than 40% who have eliminated those food groups have done so after self-diagnosis

• With the war on sugar one of the biggest health stories of the last year, it’s no surprise that more than a fifth have cut out sugar, while one in six have got rid of fat in their diet

• But could the trend for cutting things from our diet without medical advice to do so, be unnecessary?

So Patient Talk interviewed Shona Wilkinson, a leading nutritionist, to get the facts straight!

PatientTalk.Org – What are the common food groups being eliminated and why? And is the overall effect a positive one?

Shona Wilkinson- Nutricentre has done a study on over 2000 people, and we’ve actually seen that about 1 in 10 people are cutting out a common food group. These seem to really be wheat, dairy, fat, and sugar, as the predominant ones. So sometimes this can be necessary, and sometimes it can’t. So we just have to be a bit careful if were cutting out whole food groups from our diet, to make sure that were not cutting out nutrient groups as well.

PatientTalk.Org- Is it really possible to cut out fat and sugar from a diet given basic chemistry?

Shona Wilkinson- Probably not. And I don’t know quite why you’d want to cut them totally out of your diet. Why would you want to cut out fat from your diet? This was a message that was going around in the 70s and still seems to be hanging on out there at the moment, so no we don’t want to cut fat out of our diet. Sugar, yes it’s not great for us, but again we don’t want to cut it totally out of our diet. And as soon as you cut something out of your diet, the one thing you can guarantee is that you have real cravings for it, so don’t cut it totally out of your diet, we’re talking about reducing it.

PatientTalk.Org- And how much of it is intolerance related?

Shona Wilkinson -As far as the wheat and dairy is concerned, quite a lot of it. So talking about wheat, quite often people when they have wheat in their diet it can give them digestive problems, so it could be cramping, it could be diahrrea, it could be constipation, quite often a lot of bloating as well. So that can be an intolerance. As far as dairy is concerned, common side effects of having dairy are usually kind of mucus related, a blocked nose, blocked air passages, that kind of thing.

PatientTalk.Org- Okay. What is the difference between an allergy and intolerance?

Shona Wilkinson- There’s a big difference between an allergy and an intolerance, so an example would be, being a celiac. A celiac is someone who has got an auto immune disease and cannot have gluten in their diet. So that’s an actual allergy. The difference there would be someone who gets digestive problems after they’ve had gluten. So rather than it being very severe it could be just a bit of bloating. So they are very two distinct different things.

PatientTalk.Org – So in terms of severity, an allergy is a way more severe problem than an intolerance?

Shona Wilkinson- Absolutely and it can in some cases be life threatening.

PatientTalk.Org – Why has gluten intolerance increased in the last few years?

Shona Wilkinson- Yes gluten intolerance has seemed to increase in the last few years and there’s two schools of thought about this. Partly because one reason could be its quite trendy at the moment to follow a gluten free diet. The other reason is purely the amount of gluten we have in our diets nowadays. So we may have toast or cereal for breakfast, followed by a sandwich or baguette or some sort for lunch, followed by a pasta meal in the evening. That’s quite a common diet for a lot of people nowadays, and if you think about it that’s wheat, wheat, wheat for every single meal, and it’s just becoming too much for our bodies to deal with. So if you’re in that kind of situation, it’s just a matter of reducing your intake, or perhaps cutting out of your diet for 12 weeks and then slowly reintroducing it at a steady slow level and letting your body let you know what is the amount it can deal with every day.

PatientTalk.Org – What is the difference between celiac and gluten intolerance?

Shona Wilkinson – yes so celiac is an actual auto immune disease. It’s medically recognized and it can be life threatening. An intolerance is when you get slight digestive conditions after eating wheat containing food. So they are very different, one is a medical condition and one is more an intolerance that you just can’t cope with it as much.

PatientTalk.Org – What is a juice diet and how would it work?

Shona Wilkinson – Yeah, the juice diet again is quite trendy at the moment, especially it being January. Basically its people living for probably usually about 7 days, just purely on juices. We have to be very careful about this because it’s not really training you on how to eat healthily so by the end of your juice diet you can just go back to your normal unhealthy eating habits. But also with juices, they tend to be predominately fruit, which can be high sugar content. So not the healthiest of thing, not something a nutritionist usually recommends.

PatientTalk.Org- Is there much evidence of self-diagnosis? How is it done? What are the dangers, if any, associated with self-diagnosis?

Shona Wilkinson – Yes the study done by Nutricentre shows that 40% of people have eliminated food groups from their diet just on self-diagnosis. This is usually just by monitoring their symptoms, some people keep a food diary and monitor any symptoms they’ve got after they’ve eating a certain type of food. A lot of people reading things on the internet. There aren’t really any dangers of this unless you’re cutting out a food group and not getting the nutrients that you need. So for example if you become a vegan, then you have to be careful that you’re still getting the nutrients that you need there. Self-diagnosis can also be done through a blood test, which is quite an accurate way to see if you’ve got a food intolerance. There’s lots of other tests out there which I wouldn’t necessarily recommend, but a blood test is the most accurate.

PatientTalk.Org – Does this trend suggest a decrease in confidence in traditional health care providers?

Shona Wilkinson- I don’t think it does, I think it’s just that people are more health aware nowadays, and they have access to more information through the internet.

PatientTalk.Org- What common ways are used by empowered patients to improve their health?

Shona Wilkinson- Yes, I think people are now more aware of their health. They’re more aware of where to find out information. I think also people know that if you cook your food at home you know exactly what’s going into that food. Whereas if you buy a ready meal for example you can probably guarantee it’s got sugar and salt in it to begin with because that’s what our taste buds like. So I think the health empowered patient is knowing that they want to cook their food at home and be a bit more aware of exactly what they’re eating.

PatientTalk.Org- Finally what advice would you give to somebody who has just diagnosed themselves with an allergy or intolerance?

Shona Wilkinson – Yes I wouldn’t like to think that anyone is diagnosing themselves with an allergy that has to be done by a medical professional. If they think they have a food intolerance, try keeping a food diary and making sure that you do. And perhaps speak to a nutritionist to get some advice, the best way to deal with this.

Food Allergy and Food Intolerance Week – share your food allergies to help us raise awareness



This week is Food Allergy and Food Intolerance Awareness Week.

The aim of this blog is to try and raise awareness of food intolerances and food allergies.  I only became aware of the seriousness of the issue when I first met my wife to lives with an intolerance to lactose.

To help us to achieve this goal we would like your help with two things:-

a) Please share the graphic below to show your support and to honor people with intolerances and allergies.

b) Secondly if you suffer from a food intolerance and food allergy please use the comments box below to tell our other readers a bit more about it.  The more people know the better we can support you.

Thanks very much in advance.
