Most Common Food Intolerances

Supermarkets have whole aisles dedicated to it. Restaurants have menu sections catering for it. People are more and more aware of it and their own personal ones. Food intolerance is something of a buzz topic. With free-from alternative foods and drinks for pretty much every food now available, it is becoming increasingly common to be aware of your food sensitivities as it is no longer a case of being afraid of what you might find. From gluten intolerance to lactose intolerance, there are a wide range of foods, drinks and substances you can have a sensitivity to and you level of sensitivity can be higher or lower than someone else’s.

But some intolerances are more common than others, so here we take a look at some of the most common food intolerances and the symptoms they cause. If any of it sounds familiar, it may be time to take an intolerance test.

Gluten Intolerance

Sometimes known, incorrectly, as wheat intolerance, gluten intolerance is incredibly common. In fact, most of the items you will find on a free-from aisle in a supermarket will be made to cater for people living with gluten intolerance. From pizza’s to beer, gluten is everywhere. When you’re living with gluten intolerance you can expect to experience these symptoms when you eat gluten;

·       Bloating

·       Diarrhoea

·       Headaches

·       Smelly Feces

If you’re experiencing any of these symptoms regularly, it may be that you’re living with gluten intolerance. To find out you can take an intolerance test.

Lactose Intolerance

Unfortunately, as with gluten, this ubiquitous substance is found in a LOT of different foods and drinks. Lactose intolerance can be triggered by a wide range of foods including milk, butter, ice cream & most dairy products. What fun is a life without ice cream? Well, fear not, as the trusty free-from aisle has you covered again! Even food giants Ben & Jerry’s cater for lactose intolerance with a number of their top flavours now offered in dairy free form! If you’re living with lactose intolerance, you may experience:

·       Flatulence

·       Diarrhoea

·       Stomach Rumbling

·       Nausea

Sound familiar; then you may be living with lactose intolerance.

Caffeine Intolerance

There are a particular population of people who had to do a double-take there. Surely not. Not the morning bringer of energy?! But yes, unfortunately, some of us are intolerant to caffeine. With millions across the world enjoying their morning coffee to wake themselves in the morning, it is incredibly likely people are drinking it, intolerant and unaware. So what should you be looking for if you think you may be intolerant to caffeine?

·       Insomnia 

·       Anxiety

·       Migraines

·       Fatigue

These symptoms are all red flags for caffeine intolerance. Find out whether your suspicions are correct with an intolerance test.

How A Food Intolerance Test Will Help With Your Summer Body

We’ve all got our #BodyGoals as we look towards the summer. Whether it’s a ripped eight pack or just a bit less sagging, you’ve probably accepted the fact that you’re going to have to make some changes to your diet to get the results you’re hoping to achieve by the time the lighter evenings roll around. So you know you need to cut out the processed foods, a few less takeaways and probably cut back on the booze. But did you know that a food intolerance test is absolutely essential if you’re going to achieve your body goals this year? Why? Read on to find out.

Symptoms Of Food Intolerance

When you take a food intolerance test, you’re looking to identify foods that could be causing you symptoms that are holding you back from achieving your dream body but could also be stopping you from achieving your professional and personal goals. Symptoms of food intolerance include:

  • Bloating – Where are those abs you’ve been working hard for? They’re being hidden by a stomach full of gas caused by foods that provoke digestive distress.
  • Sickness & Diarrhoea – When you are sick or have a severe bout of vomiting & diarrhoea, your body expels large quantities of water, this can lead to water retention when you next consume water which will give the appearance of looking fatter than you actually are.
  • Brain Fog – A food intolerance disrupts sleep which can cause a cumulative fatigue effect which has been called ‘brain fog’. This can have serious adverse effects on both your personal and professional life as you struggle to balance home and work lives.

These symptoms can all contribute to your ability to perform the exercises necessary to achieve the body of your dreams, but also mask the results of all your hard work. Taking a food intolerance test can help you identify the foods that are causing you these symptoms.

Food Intolerance Test & Elimination Diet

So, you know you need to take a food intolerance test, but how exactly do you do this? You can find a test suited to your budget here. Using a small blood sample taken by you in the comfort of your own home, we test you against over 40 common food intolerances to find your unique intolerance profile. Using this knowledge of your personal intolerances, you can perform an elimination diet where you remove your problem foods from your diet before gradually reintroducing them once your tolerance level is reset. As part of your results, you will receive advice on how best to perform an elimination diet to ensure you get the maximum effect.

Allergy Testing Before Giving up Your New Diet

So you’re a couple of weeks into your “New Year, New Me” quest and, frankly, the only thing new is the constant state of exasperation at the fact your new diet appears to be doing absolutely nothing. Your goal dress you bought to wear to that wedding you’re dieting for still clings stubbornly around your stomach. What is the point, might as well grab the ice cream, stick some loungewear on and ignore the world outside. PUT DOWN THAT MINT CHOCOLATE CHIP. We have the answer;

Intolerance & Allergy testing.

That’s right, the food you’re eating IS the problem but NOT in the way you think. Bloating is an incredibly common side effect of a food intolerance or allergy and, when you’re looking to lose a few pounds around the stomach, it can be the difference between sticking to and giving up on your new diet.

New Food, New Problems.

When you started your new diet, you have probably introduced a lot of new foods that you either haven’t eaten a lot of or may even never have ever eaten before. So as you have been losing body fat, your food intolerance has been masking your progress by filling your stomach with gas. Incredibly annoying but intolerance and allergy testing is your salvation here.

How Does Bloating Work?

Bloating occurs when you eat a food to which you’re intolerant. When you have an intolerance, your body doesn’t produce enough enzymes to break down the problem food, and so bacteria does the job instead. The problem being that when they do so, they create an excessive amount of gas which becomes trapped in the stomach. As a result, the stomach expands, leaving you with that bloated feeling. It’s time to take action and identify the food that is irritating your gut and keeping you out of that body goals dress.

Intolerance and allergy testing is available to suit all budgets on our website.

How do I know if I have a food intolerance?

Before you commit to a food intolerance test you’re probably wondering what you should be looking for that might indicate a potential food intolerance. Different food intolerances manifest themselves differently in one person than they may in another. But, there are a group of symptoms that are generally recognised as associated with a potential food intolerance.

Here we take a look at some common symptoms and the intolerance they could be indicative of.


Bloating is caused by the excess production of gas during the digestive process. When you have a food intolerance, your body struggles to digest the problematic food which slows down the process. As a result, the enzymes spend more time breaking down the food which means more time spent producing gases. These gases then become trapped in the stomach leading to uncomfortable bloating. You may find that you experience bloating whenever you eat a certain meal or food. If this is the case, it is very likely you’re living with a food intolerance.

Intolerances that cause bloating: gluten, milk, eggs.

Brain Fog

Brain fog is the experience of fatigue and an inability to focus on tasks for any period of time. This condition can be debilitating if left untreated and can have a serious impact on all aspects of life. Brain fog can be caused by a number of different factors including the foods you eat. When you sleep, your brain takes this opportunity to recover from the oxidative stress experienced throughout the day. To do this, it requires a good flow of oxygen. When you have a food intolerance, your nasal passages can become inflamed and restricted. This prevents a sufficient amount of air getting into your lungs and oxygen into your blood. When your brain doesn’t get the oxygen it needs, it can’t fully recover. This can leave you in a near constant state of fatigue known as brain fog.

Intolerances that cause brain fog: wheat, lactose, fructose.


Unsurprisingly, when your body realises you have eaten a food to which you’re intolerant, it tries to evacuate that food from your system as soon as possible. This means the normal digestive process simply won’t cut it. In an effort to expedite the process, your body will draw water into your bowels which combines with the food to create more fluid-like faecal matter. This aids its progress through the digestive system resulting in a near-immediate excretion. Diarrhoea can have significant negative health impacts, the water drawn from the cells to make the diarrhoea can leave you dehydrated and  causes an electrolyte imbalance. It is vital to identify any food intolerance that might be causing you to have regular bouts of diarrhoea.

Intolerances that cause diarrhoea: peanut, dairy, wheat.

How a Food Intolerance Test can help

Being aware of food intolerances is absolutely essential to maintain good health. When you know which foods you need to avoid, you’re able to plan your diet to avoid the symptoms above as well as other symptoms such as NAUSEA, HEADACHES, RASHES & OTHERS. You can find our range of intolerance tests, suitable to all budgets, here.

How does food intolerance testing work?

If you aren’t informed on it, food intolerance testing can feel more like a mystic art than a science. After all, it’s quite impressive that with such a small sample size (just a few hairs or drops of blood) we can deduce how you’ll respond to an abundance of different foods. But how does it all work?

Today, we’re drawing back the curtain to show you how getting tested against food intolerances actually works.

Order your Intolerance test

First, you order a test. Depending on whether you’ve opted for a blood or hair test, you’ll either print out a form or receive a kit in the post. The former is exclusively for hair tests and the latter – you guessed it – for blood only.

The reason for this is because of the ease with which hair samples can be obtained, compared to blood samples, which require the use of sterilised tools to help you safely pull out your blood.

For blood testers, this is the slightly uncomfortable part. But don’t worry, it’s not nearly as bad as a blood test at the hospital or having an injection. You’ll have to prick your finger using a lancet supplied in the testing kit and encourage your blood to flow out so you can send us your sample.

Hair testers have a better time with this, as they only need to supply a few relatively new hairs, which naturally fall out throughout the day anyway. Provided you don’t share a brush; you can take a few hairs from it and send them in.


Next is where all the technical bits happen. Once we receive your sample, you’ll be notified, so you know it won’t be too long before your results are ready.

First, all test samples are sorted, based on where they’ve come from, which test the customer is having, etc. Then, samples are taken through to the lab, where samples are tested. Here’s how the process looks for blood samples;

“Your blood sample is turned into plasma (the liquid component of blood), and our lab technicians then analyse the immune-mediated intolerances, which produce IgG4 antibodies against 40 foods to generate a report. The report is then uploaded to your secure customer area for you to download.”

Your report indicates the severity of any reactions your sample indicated. It’s quite common for intolerance results to highlight foods you’ve regularly been eating – you might just need to vary your diet a little more.

How Do I Know If I Have Lactose Intolerance?

Between 30 and 50 million adults have Lactose Intolerance making it quite common. The question is, are you lactose intolerant?

Several different symptoms come with a lactose intolerance, and they usually occur within a few hours of consumption. Below are a few symptoms that may indicate an issue if they coincide with eating products that contain lactose.


It makes sense that consuming foods you’re intolerant to would disrupt your digestive system and lactose can have a real impact on your bathroom trips. Diarrhoea after lactose is an indicator of an issue and can lead to dehydration and electrolyte imbalance.

Stomach Cramps and Pains

As well as diarrhoea, people with lactose intolerance will often experience extreme stomach cramps. The gases produced by the stomach fermentation process cause this pain. The pain and bloating experience is not related to the amount of lactose imbibed, but the level of intolerance the individual has.

If you’re passing infrequent, hard stools or are having to strain excessively, you are likely experiencing constipation. Bacteria ferment the undigested lactose in the stomach, which produces methane gas and this gas is thought to slow down the movement of food through the gut. Constipation is less likely than diarrhoea but is still a potential symptom.

Other potential symptoms

Other symptoms that have possible ties to lactose intolerance include:

  • Extreme Fatigue
  • Headaches
  • Brain Fog
  • Eczema
  • Joint Pain

Though they have not been proven as established symptoms, they have been reported frequently in case studies.

Other intolerances or allergies cause all of the above symptoms. To establish what might be causing the above symptoms for you, you should take an intolerance test.

Allergy People making a difference

There are so many people looking to make a difference in their lifestyle and diet, but it does not stop there. Allergy testing people are making a difference and spreading the word, so we thought it was time to celebrate their awareness and ability. Look at how we have helped some of our customers to improve their lives, and how they have spread their own awareness.

Chris Jones – Lifelab Testimonial

“My experience was great, particularly as I messed the first one up so getting a second kit was easy.  I was intrigued by the results and have found that reflecting this in my diet has helped my health and well-being. But overall the whole process was easy and I would recommend, in fact, I already have. Thanks!” – Chris wanted to make a change in his life, and he was dedicated to improving his diet. He did this withLifelab Testing and allergy testing kits, and he loved the whole process, recommending it to any others who suffer from food allergies.

Danielle Lloyd – Spreading the word

We’re absolutely delighted to have helped model and TV star: the AMAZING Danielle Lloyd, kickstart her year in the best way possible by helping her discover her Intolerances with an easy to use at-home Intolerance Test ? Just take a look at what she had to say about her Lifelab Testing experience below! ??

“I’m starting the new year feeling great after finding out what was causing me bloating and pain after eating food, with Lifelab Testing‘s at-home intolerance and allergy testing kit. The results were so good that my son Harry did a test, too, and since changing his diet to gluten free, he hasn’t been in any pain. My results showed I had to cut out eggs, yoghurt and white beans, which I eat regularly as part of a healthy diet, so it’s been a total change but it’s for the better and means I’m not bloating after meals anymore! The test was so easy to do and really thorough as it checks over 159 intolerances, so I knew it’d be a good way of finding out what was causing the pain.”

Lauren McQueen spreading the news

We are so proud to have helped people cope with their allergies, and with people coming to us and ask how we could help them with their allergies through allergy testing, they wanted to spread the word. Lauren McQueen was another one, check out her testimonial below and also, you can hop over to Instagram to find out more:

I have been struggling with bad breakouts on my skin alongside extreme bloating of my stomach. I contacted Lifelab Testing and purchased their Complete Intolerance Test without any hesitation. I took my blood sample and returned it to Lifelab for testing. Within days, my results were ready in the ‘my account’ section. After I studied my results, I was put in contact with Lifelab Testing’s Nutritional Therapist who helped me to understand my results more and how to structure my diet around this. With this knowledge, I am now aware of what I should eat less of and what to completely avoid.

Lauren shared her experience on her Instagram page, and utilising our nutritional therapists, she was able to improve her health and lifestyle. We are very keen to see people spread the word about allergies and healthy living.
