Food intolerances

While food allergies are seemingly rare, food intolerances are much more common and widespread. A recent study found that one in five adults in the UK report suffering from a food intolerance. So, what’s the difference between allergies and intolerances, and how do you know if you have one?

Food allergies are immune system reactions and range in severity. They vary from a mild skin rash right through to a life threatening anaphylactic shock. Fortunately, food allergies are easy to identify and can be checked using a blood sample for IgE antibodies. Less fortunately, if you are diagnosed with food allergies then you will need to avoid those foods for life.

Food Intolerances

Food intolerances are a response in the digestive system as opposed to an immune reaction, and may have multiple causes. Indeed, many food intolerances are the result of enzyme deficiency. For example, you may not produce enough lactase to digest lactose in dairy, or enough protease to digest gluten. It’s also possible you may have low stomach acid, which will prevent you from breaking certain foods down properly. Some people are sensitive to caffeine and to the natural amines in cheese and chocolate. Moreover, certain foods contain natural toxins, such as night shade vegetables, or additives that you may be sensitive to.

Food intolerance reactions tend to have a slower onset than allergic reactions, are often dose related, and are not usually life threatening. They can however, be deeply unpleasant and even affect your quality of life! Furthermore, since the symptoms of food intolerances are so diverse and play out in every aspect of our health, it is very common for people to live with them for many years before identifying the crux of the problem.

So how can you recognise food intolerances?

If you suffer from bloating, cramps, diarrhoea or constipation, and your doctor has ruled out allergies and checked for other typical causes, then it is quite likely that you have a food intolerance. Similarly, if you suffer from headaches, joint pain, dark circles under the eyes and brain fog, then it would be wise to investigate the possibility of food intolerance.

So how do you find out what causes you the problem?

Food intolerances are notoriously difficult to diagnose. Partly because the reaction often occurs hours or even days after an offending food is eaten. And partly because very often multiple foods are contributing.

If you think you may have a food intolerance and want to investigate, then the first step is to keep a food, mood, and symptom diary. If you notice a pattern with one or more foods, take them out of your diet for at least nine days. After this, reintroduce the suspected foods one day at a time and note any reactions. Sometimes, when you monitor your diet in this way, the offending foods become obvious and, once eliminated, your symptoms improve.

While this approach has proven to be useful, I sometimes find it is also limited. This is because people often consume small amounts of foods, like milk or corn, without realising. Even small amounts can confuse the results. It can also be challenging to eliminate multiple food groups for several weeks. This means people often give up before they can gather accurate results. If this is the case for you, or if you follow the protocol correctly and still don’t manage to identify the offending foods, then food intolerance testing may be necessary.

Food intolerance testing

I use Lorisan food intolerance tests with my clients, which analyse IgG antibody reactions to 100 food and drink ingredients. Many nutritional practitioners offer food intolerance testing, but not all have undertaken the necessary training analyse the results and ensure sucessful patient outcomes. Alongside testing,  it is necessary to investigate how well your digestive system is functioning as a whole. If you have low stomach acid or insufficient levels of a particular enzyme, or if you have imbalanced levels of beneficial and pathogenic bacteria in your gut, this will need to be addressed before your symptoms can improve. This is what I offer my clients.

 

The Lorisan 100 food intolerance test can be purchased by clients and Reinvent members for £199. New clients can purchase the Lorisan 100 food intolerance test plus a 60 minute follow-up phone consultation for £299. When eliminating whole food groups it is vital to ensure that your diet remains balanced to avoid nutrient deficiencies. That is why I create a bespoke nutritional therapy plan for each of my clients to ensure long term success.

 


“My 2 and a half year old son was having numerous problems including eczema, bad nappies (as in not one normal one since birth), asthma and projectile vomiting (to name a few). My GP told me they used to call them “sicky babies” and he would grow out of it, I would just have to put up with the mess for a while… A great help as you can imagine! Rosie immediately considered the symptoms and it turns out he’s simply severely intolerant to dairy! So from pints of milk a day to none, within a week his nappies were normal and he was feeling so much better. He also no longer sounds like Darth Vader in his sleep!! All in all, Rosie has been amazing and it’s great to know I can turn to her with any questions I have with ongoing issues. I can thoroughly recommend her!”
