Food Intolerances: What are the Symptoms of Food Intolerance and What Tests are Available?
While less than 2% of the population suffer from food allergies, it is estimated that more than 20% of the population suffer from food intolerance. Food intolerances can affect anyone at any age, (we commonly work with children who have an intolerance to food) but since symptoms often occur some time after the food has been eaten it can be difficult to find the problem food. Years of research has found the basis of what causes allergy and food intolerance. Poor digestion causes your immune system to begin to attack partially digested components within the food that “leak” through the intestine and can migrate around the body. Sometimes that partially digested components lodge in the intestinal wall, sometimes in a membrane around a joint or even the brain. Antibodies quickly find these components and indicate to the rest of the bodies and this triggers the immune system and causes inflammation. Inflammation causes irritation: soreness, pain and swelling
There are many techniques that have been developed through the years to determine food intolerances. Some techniques were developed before scientists discovered the immune response, for example muscle reflex testing, and acupuncture. These techniques increasingly use electronic signal processors to improve their accuracy. However, these techniques can be still be compared to using a piece of seaweed for weather prediction. It takes someone with extremely good powers of judgement to understand a muscle reflex or voltage change due to a food sample being contacted with the skin. We often meet with patients who have been tested and told they are intolerance to a wide range of staple foods, fruit and vegetables. Their symptoms can improve sometimes but they often end up with a very unbalanced diet.
A more modern and clinically proven technique looks at the root cause of the food intolerance symptoms, the immune system. Indeed, a clinical trial of immune system tests found that most people with IBS that avoided the foods suggested by an immune test had their symptoms significantly improved. These tests do need a blood sample. With the right training, blood sampling is virtually painless and takes a few seconds. A sterile finger pricker lances the skin and a blood drop appears. The drop is collected and that is that, you don’t really need a dressing and its hard to see where the blood came from a minute later. That small blood sample is taken and the levels of the antibody determined by a laboratory. Some tests need to be sent away (york test). Our specialist practice in Inverness has a small lab where the tests can be done whilst you wait (
food intolerance testing inverness), taking less than one hour. The food intolerance test results are very unambiguous and can be used to guide an elimination diet with some certainty.
The immune (blood) testing is a lot more accurate than the old fashioned ways of testing. Sometimes people go through the mill, completely unnecessarily.
A patient (Mr. M.) came to us with a huge list of things he was told to not eat by an electronic muscle reflex test. He was an active young male who was told to avoid all grains, milk, nuts and yeast. He was suffering from rhinitis (blocked nose that would not go away) and had followed his food avoidance diet based on the electronic results and his symptoms had still not got any better. A big issue for him was that he used to like going out with his friends to go for pizza and have a few beers. He had lost a lot of weight and felt hungry all the time because of his active job.
I blood tested him and found that he gave a very weak positive result to oats and yeast (so weak it took imagination to see the positive blue spot on the test plate). So he had put up with not being able to go get a pizza, not being able to pop out for a sandwich at lunchtime and spent a lot his time being starving (active outdoor job in Scotland – you need food!!) for no particular reason at all.
So he is now back onto a balanced diet again and can enjoy a beer this Christmas.
If you have been electronically tested and given a big list of foods that you are intolerant to, it might be a good idea to get a second test done somewhere else perhaps by the immune method and compare the results.

All About Food Intolerance
Food intolerance is becoming much more of a household phrase these days. For those who haven’t thought about it much or never had a reason to look into it, this is a basic guide to what it is, what some of the most common intolerances are, and some other related information.
Food intolerances can come from a variety of sources. For example, some people can’t tolerate citrus fruits or other acidic foods. The food intolerances that trouble most people are chemicals (such as aspartame or preservatives), natural compounds (like caffeine), wheat and gluten, and, of course, lactose.
Sometimes it’s hard to distinguish a food intolerance from a food allergy. Their symptoms can be quite similar, but actually they are completely different bodily responses. A food intolerance is a digestive system problem.
If you have a food intolerance, you might experience headaches, gastrointestinal problems, or weight gain. (Wine, cheese and chocolate are notorious headache causers.) Gastrointestinal issues can include gas, bloating, constipation, or diarrhea, which are sometimes mistaken for Irritable Bowel Syndrome. You might also have allergy-like symptoms such as a runny nose, hives, or difficulty breathing.
Lactose intolerance is one of the most common things people suffer from. It is caused by a shortage of the lactase enzyme. Instead of digesting lactose normally, people with too little lactase can’t process milk sugars properly. When they consume dairy products, the result is fatigue, nausea, and a host of other digestive problems such as gas and bloating.
How serious is lactose intolerance? Children younger than two are especially susceptible to it. These children often need a special non-dairy formula to ensure proper nutrition. Most adults with lactose intolerance (5% of all adults in Ireland and the UK) can tolerate a tiny amount of dairy in their diets. Others can tolerate none at all.
Though more rare, foods that contain artificial preservatives, sweeteners, flavor enhancers, and colors sometimes trigger painful symptoms in people with an intolerance to such substances.
Another very common intolerance is wheat or gluten intolerance. (Gluten is a protein found in wheat.) These conditions have gotten a lot of press lately, and for good reason: gluten intolerance, also called celiac disease in its most serious form, has been linked to behavioral problems, weight gain, and even autism.
Celiac disease is an incurable condition that causes the immune system to attack a person’s own body. In this case, the autoimmune response is triggered by eating foods that contain gluten. Celiac disease can cause all of the symptoms of food intolerance, plus stunted growth and skin conditions. Left unchecked, it can eventually cause bone disease, anemia, and even cancer.
Unfortunately, gluten is found in all wheat products, and even in some products made from barley, rye, and oats. That means that people with gluten intolerance need to avoid certain alcohols, like beer. Wheat can also be found in unexpected places. It’s often used as a filler in ground meat and sausage.
There are many gluten-free and wheat-free breads, pastas, and cereals – but they’re not created equal. Just because a product is gluten-free doesn’t necessarily mean it’s safe for people with wheat intolerance. Gluten-free products can contain other wheat substances. Likewise, wheat-free products might contain barley, rye, or oats.
Basically, people who suffer from a gluten intolerance must become very good label readers!
If you suspect wheat, gluten, or any other intolerance, speak with your doctor as soon as you can. They will make a firm diagnosis and give you dietary guidelines to follow.
There is a great food intolerance test on the market that I would recommend to anyone who thinks they may be affected by one or several food products. It takes the guesswork out of figuring out what is causing the problem.

If you find out you do have an intolerance, seek nutrition guidance, as when patients attempt to cut out the offending food group, it can cause malnourishment. For example, some people avoid dairy products altogether because of their lactose intolerance. Without a good substitute, they risk calcium deficiency.

How To Make The Necessary Changes For Food Intolerance
It is easy to make the necessary changes to cope with your food intolerance. As you would need to change your diet and avoid the sensitive food, it is important to prepare yourself for the changes.
Here are a few tips on how to make the necessary changes:
There are many free from foods available in the shops nowadays. Examples of free from foods are replacing diary milk for soya milk or oat milk and wheat flour for rice flour or buckwheat flour. With free from food, you can still have the food you enjoyed. Eat a variety of food at different meal time, for example, take porridge for breakfast, snack on a fruit, have a vegetable soup for lunch and a rice based meal or fish and vegetables for lunch. In order to ensure that you only eat food that will not give you intolerance, it will be a good idea to plan your menu ahead. Planning a head give you time to select the right type of food, and prevent you from slipping back to quick fix food that will make you unwell. Make a conscious effort to avoid the sensitive foods. When you go on your food shopping, check food labels carefully, to ensure that they do not contain any of the ingredients you are intolerance to. There are things you can do in advance. Certain meals can be prepared in advance such as cook brown rice, lentils or pearl barley and freeze them for use when needed. Follow a healthy eating plan using fruit, vegetables, whole grains, pulses, nuts, seeds, fish and meat. Include high energy food like lentils, sweet potato and beans for a complete balanced diet.
Food intolerance need not be a lifelong ailment, find out what your food intolerance is with laboratory test such as foodScan 113 and with proper care, you will feel well again.

Food Allergy Versus Food Intolerance
The wrong medicine for the wrong condition can increase the allergic symptom resulting in anaphylaxis and even death. Anaphylaxis is a severe allergic reaction where all the symptoms swiftly attack the entire body all at the same time.
Symptoms Of Food Allergy
Food allergy is an allergic reaction to certain types of food. The most common food allergens are: cow’s milk, wheat, peanuts and other tree nuts, eggs, fish, soybeans, shellfish, meat and certain types of drugs. The allergic reaction can vary depending on the type of allergen but they have the same number of symptoms:
- Rashes or hives begins to appear on the skin. In extreme cases, the swelling and hives can spread to the entire body.
- Swelling of the certain areas near the mouth.
- Swelling of the ear
- Redness and itchiness of the eyes.
- Runny nose
- Vomiting and diarrhea
- Difficulty in breathing and wheezing, sometime signs of asthma
Food intolerance has much of the same symptoms except the runny nose and watery eyes. Most often, food intolerance results in diarrhea and swelling of certain areas of the body.
Aside for the similarities in symptoms, a food allergy is more severe than food intolerance. Someone with food intolerance can eat small portions of the food he is allergic to. They can still enjoy the food, though in small quantities. But to a person with food allergy, that small portion can immediately trigger an allergic reaction. And if not treated at once, the patients can go into anaphylaxis.
What makes a food allergy more life threatening is because of the immediate threat to the person. Someone with food allergy can have an anaphylactic shock and start to experience the swelling of the throat muscles. This can block the air passage of the person and could result to death.
Another real danger is the sharp drop in the blood pressure of the patient. In this case, the person with food allergy may experience mental confusion and dizziness.
Food Allergy Treatment
A food allergy can be treated as soon as the symptom occurs. For rashes, there are skin creams available to ease the swelling and itchiness. The antihistamines will give relief to symptoms of runny nose, watery eyes and swelling. These medicines can be bought right in the local drugstores and does not require a prescription.
For those who experience the severe food allergy reactions, a dose of epinephrine (adrenaline), either self- injected or given by the doctor can immediately reverse the symptoms. As of now, a shot of epinephrine is the most effective treatment for food allergy and other types of allergies.
Preventing Food Allergy
Although food allergies cannot be prevented, the best way to defeat it is by staying away from the food a person is allergic to. Taking a risk will only cost you more pain in the future. So it is best to see the doctor to get a proper diagnosis and guidelines on what to eat and what not to eat.
Making the right diagnosis on food allergy versus food intolerance can be tricky. It all depends on how severe the allergic reactions are and the number of symptoms that show up on the person when exposed to the food allergen.

Food Intolerance And Diabetes Treatment
Diabetes is one of the biggest scourges of this century. Along with cardiac problems and high cholesterol levels, this condition has pushed entire generations of people into a high risk zone, where they are literally living on the edge everyday. One of the most puzzling things about diabetes is the fact that there is still a lot of confusion about what causes it. Of course, heredity, food habits and lifestyle factors play an important role. But, there are still gaps in our understanding.
According to studies conducted recently, carbohydrate intolerance could be one of the factors that cause diabetes. It certainly contributes to obesity so by natural progression, it must also contribute to diabetes. The ACCP (American College of Chest Physicians) published a new study in their journal that shows how in some people, the inability to absorb and break down carbohydrates leads to the build up of fat. Such people become obese when they are unable to digest or process carbohydrates. When this intolerance is not diagnosed, it leads to metabolic disorders in the long run. Researchers also made another interesting discovery: carbohydrate intolerance leads to metabolic syndrome, which is nothing but a collective name for medical conditions like diabetes, high blood pressure and hypertension.
Proper carbohydrate intake is an important part of type2 diabetes treatment. This is because people who suffer from carbohydrate intolerance cannot tolerate any of the simple sugars that their food provides. In such people, there is a lack of digestive enzymes. This makes it impossible to digest and absorb carbohydrates. Since the body is not getting its fair share of carbs, it goes into a starvation mode. It stores more fat. At the same time, it stimulates hunger, thereby encouraging the person to eat more. This is the reason why untreated food intolerance directly leads to diabetes and cardiovascular diseases.
It is not just type2 diabetes, even type1 diabetes may be caused by the body’s adverse reaction to food. Evidence has been collected to show how the condition shows great genetic similarity to celiac disease which is caused by gluten intolerance.
As sufferers know, there is no cure for diabetes. The most vital part of diabetes treatment is the proper management of blood sugar levels. Patients are advised to eat food in moderation, exercise and follow a healthy lifestyle so that their blood sugar levels remain stable. Food items that are rich in fiber while lean on carbs is the recommended diet since these items release sugar at a steady pace, unlike simple carbohydrates which inundate the bloodstream with high doses of sugar. Even in spite of following these regulations, carbohydrate intolerance can lead to associated problems. Therefore, such people may need to take in enzymes that help break down carbohydrates.
According to surveys and reports, more than 72% of all Americans suffer from one or another kind of food intolerance. Unfortunately, most of us are not aware of food sensitivities because the symptoms are quite subtle. The only way you can spot food sensitivity is through blood tests that confirm the same. Considering the needless suffering that people with food sensitivities undergo day after day and year after year, a simple blood test seems like a more attractive alternative.
