Food allergy, sensitivity or intolerance – which do I have?

Food allergy, sensitivity or intolerance – which do I have?

Do you suspect certain foods don’t agree with you? 
Do you have a food allergy, sensitivity or intolerance? 

There’s a lot of confusion around this subject.  Both food allergy and intolerance/sensitivity are where your body’s immune system reacts inappropriately to a food, or more specifically a protein in food.  Even food contains proteins to varying degrees.  Instead of tolerating the food as something harmless, it mounts an immune “attack”, generating antibodies to the food in the process. 

But there’s a big difference between allergy, food sensitivity and intolerance.  

Food allergies are easy to identify.  Within 2 hours of eating the food you’ve got a noticeable reaction.  Most often a rash or your throat or lips swelling up.  Allergies can be severe and life-threatening.  They are easily identified by hospital tests.  Typical tests are where the skin  on your back is pricked numerous times and a single test food is applied to each puncture to see if it reacts.    IgE blood tests can also identify allergies.  Allergies  are to do with a type of antibody called IgE.  Surprisingly, people with food allergies can take specific actions to lower their reactivity.  Eating foods and nutrients that dampen down this excessive immune response and make you resilient.  I once had a client who was an agricultural consultant.  He visited farms for a living, instructing farmers on better methods.  He came to me during winter because he felt it must be possible to conquer his hayfever (IgE reaction against pollen.  From May to October he was usually murdered by hayfever, living on anti-histamines and still struggling.  He did what I recommended.  And transformed his next summer at work into ease and comfort instead of the old story of redness, itching, sneezing and misery. 

Food sensitivities are different.  They’re harder to identify because symptoms are triggered from several minutes to 48 hours after exposure to the food.  Food sensitivities are where IgG or IgA antibodies are triggered.     

It is quite common for people to react badly to certain foods not because they have a sensitivity but simply because their digestive system is not working efficiently. So they can’t tolerate a particular food.  Having an under-functioning digestive system can cause both food sensitivity and intolerances (see below).  

Let’s talk about about intolerance that’s really just  faulty digestion.  For example lactose intolerance.  Lactose is a natural sugar found in milk.  If your small intestine is damaged or lacking friendly bacteria called lactobacillus then it can’t produce enough digestive enzymes to break down lactose.  If you have bacteria/yeast overgrowth in your small intestine which this causes lactose intolerance.  The lactose intolerance I see in my practice is usually developed over time and is usually fixable by supporting your digestion, temporarily removing the problem sugar (lactose) and supporting gut healing.   However, people of East Asian, West African, Arab, Jewish, Greek, and Italian descent might be genetically lactose-intolerant.  Their bodies just cant make the enzyme (lactase) that digests lactose and there might be a case here for long-term digestive support in supplement form.  

Then there are the people who can’t digest or tolerate high protein foods like e.g. beef.  They just feel awful after it.  The higher the protein content in the meal, the worse you feel.  This is usually related to hypochlorhydria – a fancy name for inadequate stomach acid.  By the time somebody is 50 years of age they have 50% likelihood of hypochlorhydria.   This sets them up for muscle loss, immune issues and other so-called age-related frailties.  You absolutely can help support your ability digest the protein you need for long-term health.  And I show you how.  

You’ll probably have noticed I haven’t even mentioned coeliac disease and non-coeliac gluten sensitivity so far.  That’s coming soon.  I grew my knowledge and ability to help people struggling with this exponentially after I discovered a serious gluten sensitivity myself.  In my case, the main effects were cognitive and social – resulting in many decades of being unable to read situations, get along with people, connect, and function in a world of normal people.  Learning that the 2 most common symptoms of coeliac or non-coeliac gluten sensitivity are fatigue and brain issues was a game-changer (side note: I healed my brain).  If you think you have an issue with gluten you’ve come to the right place to get help.    

Common causes of poor digestion that lead to food sensitivities and intolerances include:

  • Not chewing – your stomach has no teeth and so will not be able to cope with large chunks of hard-to-digest food (eg meat, fish, eggs, cheese, beans)
  • Inadequate stomach acid – this can lead to bloating and (ironically) acid reflux, especially after protein-containing food.  Protein cannot be digested properly without the acid. Pain, bloating, acid reflux, IBS, constipation or diarhoea can ensue.  Nutritional intervention and one-on-one self-regulation coaching is a game-changer here.  Why?  Because it’s not just about getting enough nutrients in.  If you’re living in chronic stress you’re diverting energy from health and repair and putting all your resources into getting ready to run, fight or hide.  Most of us spend around 70% of our time living in stress.  This pushes the genetic buttons that eventually cause disease.  Most of my patients see a reduction in their “triggerability” within weeks.  Reduce your reactions to the circumstances and challenges in your life and you liberate energy to heal.   I show you how.    
  • Poor gallbladder function/pancreatic insufficiency – this is where not enough digestive juices (enzymes, bile salts) are pumped into your intestine to continue the digestive process. This can also cause symptoms. Typical symptoms might include pale or floating stools or discomfort after eating fatty foods. If you don’t make enough stomach acid, then the flow of pancreatic juices from the gallbladder will not be triggered.  You’ll have problems further down your digestive system.  
  • Dysbiosis – when you have inadequate good bacteria in the gut and overgrowth of pathogenic bacteria or yeasts, food intolerances usually follow. This is because pathogenic species produce irritating by-products that damage your gut wall. This causes leakage.  It allows undigested matter to pass from your small intestine into the blood stream. There the immune system mounts an attack on the “foreign” matter. Only fully-digested food should be permitted to pass from the gut into your blood. If your symptoms are worse after eating refined foods, sugar or alcohol or if these are regularly in your diet, you could be dealing with dysbiosis.  Your gut health can dramatically improve with the right intervention and support.

Is IBS making your life a misery?

A diagnosis of IBS means your doctor can’t find the cause of your diarhoea, constipation, bloating, abdominal pain or excessive flatulence. You don’t “just have to live with it” or rely on meds that don’t address the root cause. Relief IS possible I see it a lot.

Here are the most common drivers of IBS in people who consult me. There is a VERY high success rate when you find out which are relevant to you and address them systematically.

Do you have the right balance of bacteria?

If you have IBS, you definitely don’t! There are more bacteria living in your digestive system then there are cells in your body. They need to be in the right balance for a healthy bowel. Did you know that bifidobacteria (a beneficial bacteria) are essential for the formation of soft but solid stools. Avoiding both constipation and diarrhoea. Lactobacillus, another “good bacteria” produce lactic acid. Lactic acid inhibits the growth of pathogenic (“bad”) microorganisms in the gut.

Bacterial overgrowths, parasites (more common than you think!) and lack of friendly species in your colon are factors in IBS. The imbalance damages the lining of your gut wall and this can also lead to food sensitivities. If you have had to take antibiotics or were not breast-fed you will not have a healthy balance of bacteria in the gut and will be at higher risk of digestive disorders. “Bad” bacteria feed on refined products, seed oils and alcohol. Taking steroids or oral contraception also upsets the bacterial balance in your gut. Find out with the right lab test.

Are you super-relaxed, never react emotionally, never stew over ANYTHING?

Tiredness, low mood, anxiety and insomnia are found in almost all IBS sufferers [1]. Stress, unconscious or not, causes degradation of the lining of your small and large intestine, increasing risk of bowel disorders. Did you know that if your diet is short of relaxing nutrients or you’re not able to digest them then metabolic or emotional stress escalates. Take the stress quiz on my home page to assess your stress.

Are you dehydrated?

Sugary/salty/dried foods, caffeinated drinks, fruit juice and lack of water-rich foods (fruit and non-starchy veg) increase your body’s need for water. Water is needed to make digestive juices. Without enough, you can’t digest properly and there will be downstream effects sooner or later. Also, water softens the stool and makes it easy to pass. A simple test for dehydration. Pinch the skin on the back of your hand, then let it go. If it doesn’t spring back to normal within half a second, you’re dehydrated and its worth exploring why.

Do you have enough minerals and vitamins in a form your body can digest and use?

Certain nutrient deficiencies can cause digestive problems. For example, deficiency in vitamin B3, B complex or vitamin A can cause diarhoea whereas low B12 or magnesium can contribute to constipation. Magnesium is needed in order to relax the bowel so a stool can be passed. If you are stressed or have insomnia it could be a sign you are short of magnesium. Vitamin B5, B6, folic acid and antioxidants are needed for everyday repair and maintenance of your bowel. Overconsumption of stimulants and refined foods (including alcohol), or smoking, depletes you of nutrients needed for a healthy gut.

Is your body making enough digestive juices?

Did you know that in order for you to break down the food you eat your stomach needs to produce hydrochloric acid. You need enough of certain vitamins and minerals (especially zinc) to make this vital acid. When the food empties from the stomach into the small intestine the mixture needs to be very acidic in order to trigger the release of digestive enzymes and bile salts to complete digestion. If this does not happen then the food sits undigested and fermenting in the gut. This inadequate digestion can cause bloating, flatulence, constipation or diarrhoea.

Do you have food sensitivities?

If you’re stressed or don’t make enough digestive juices then you’re headed for food sensitivities. These are where your immune system reacts inappropriately to certain foods. Symptoms can take 48 hours to appear so it’s hard to pinpoint. Unless you test (IgA and IgG) or do a guided elimination challenge diet. The 2 most common food intolerances are to wheat and dairy products, which contain proteins that are difficult to digest. In a small number of people people, their IBS is an undiagnosed non-coeliac gluten sensitivity.

Do you eat enough quantity and variety of prebiotic fibre?

This fibre is found in certain plants. Friendly colon bacteria feed on it and make short chain fatty acids and these are a critical part of the daily repair of your bowel. Insoluble fibre, found in wholewheat, is a gut irritant and many people find that it makes everything worse. Some people are intolerant of fibre and usually those people have SIBO.

SIBO (Small Intestinal Bacterial Overgrowth)

A review of studies by the National Institutes of Health showed 19-37% of people with IBS have SIBO compared with a rate of 0-12% for healthy people [2]. This is where (usually harmless) bacteria or fungi proliferate in your small intestine. The overgrowths damage your gut wall. Now you’re not able to make “brush border enzymes” within your small intestine to digest your food. The food turns toxic and becomes food for the bacterial overgrowth. Leaking of undigested gut contents and bacteria into your blood then causes massive inflammation. This can range from depression/anxiety to full blown bowel diseases, skin complaints and all chronic metabolic diseases. And of course, IBS. 95% of the patients I refer for a simple breath test DO have SIBO. They tend to experience radically improvement after addressing the root causes (not just the actual overgrowth itself).

Do you have low thyroid function (hypothyroidism)?

Constipation is a common symptom of underactive thyroid. Blood tests do not always give the full picture – thyroid function may be low enough to give symptoms but not enough for a doctor to recommend medication. This is a less common cause of constipation than most of the factors mentioned above. A simple test using an accurate basal thermometer will rule this in our out. If you’re already on thyroid meds then addressing your struggling thyroid is going to be part of the solution to your gut issues.

If you have any unexplained pain, change in bowel habit or have black/tarry stools you need to consult your medical practitioner immediately. Nutritional therapy is not a substitute for medical treatment.
