Twelve Signs of Food Intolerance: #1 – # 6

There are so many mild symptoms which we often ignore – or we just put up with them – this is typical food intolerance!  Nonetheless they are precious signals that something is wrong.

‘Symptoms are signals’

# 1. Anaemia, low iron levels 

Are you taking iron supplements? Do you lack energy or feel breathless frequently? Chronic tiredness is common. However few realise all of these could be anaemia – a food intolerance issue.

The cause is often Leaky Gut syndrome: When you cannot digest ‘modern’ foods like grains, nightshades or dairy foods – the gut becomes damaged, in particular the small intestine. The tissue develops tiny holes and becomes ‘leaky’.

Suddenly its function is compromised – including its ability to absorb nutrients like iron and calcium. But the double-whammy, bad things get absorbed.

So – good things are lost from the body without being absorbed… and many anti-nutrients remain in the body when they should have been eliminated. Of course the outcome is illness – which in time turns into chronic conditions.

# 2. Mouth ulcers, cold sores

So painful, so long lasting!  We suffer in silence for days – even weeks, have difficulty eating, talking – even brushing teeth. And there is no effective treatment. Ask yourself … why does it happen?

The appearance of cold sores or mouth ulcers is a sign of a stressed immune system. In other words your immune resources are stretched to capacity and cannot even fight off a minor infection.

But if you have undetected food intolerance – the ‘problem’ foods you eat every day generate ‘foreign’ things which your immune system must battle all the time. This uses up immune resources. So while your body is busy fighting these things, infections jump in and multiply where they would usually not get a chance.

Mouth ulcers and cold sores are a hallmark sign of food intolerance.


# 3. Irritable Bowel Syndrome – IBS

Alternating bouts of constipation and diarrhoea. These distressing symptoms are accompanied by:

  • Malabsorption of nutrients – e.g. calcium, iron
  • Dehydration
  • Rectal trauma – leading to haemorrhoids
  • ‘The blues’ – sometimes depression

PillsIBS is common – but few doctors understand its links to food intolerance. They turn straight to medications, or even surgery – rather than search for the cause.

Obviously removing the cause is a permanent solution. Irritable Bowel is almost always food-related – so use the Journal method – to check for Gluten or Dairy intolerance in the first instance.


#4. Sinusitis

Chronic sinus pain, or recurring sinusitis is true a sign of food intolerance. It may have begun in your teenage years, or early twenties. Sometimes the sinuses become so swollen for so long (with the accompanying headaches) that they become infected.

And sinus infections are very hard to shift – even with antibiotics. As a former sufferer – I found the best plan was to find out the cause – and remove it from my life.

With more than a decade of helping people get well – we know that discovering food intolerance and ‘switching a few foods’– clears up chronic problems like this.

Once you pin down the culprit – for the rest of your life – you’ll be able to choose to get sinus pain – or decide to eat something else. Wouldn’t that be great? 


# 5. Chronic cough, bronchitis, asthma, colds and ‘flu

Chronic respiratory conditions are frequently related to food intolerance. Once again it is the immune system responding by generating histamines and fluids with inflammation – this time in the lungs and nasal passages.

A stuffy nose may seem minor – but it leads to headaches and chronic congestion followed by infection – not to mention difficulty sleeping.

ChildrensMany children suffer serial colds and cough viruses – with no apparent reason. Of course as parents we give them medicines to try and ease their symptoms and help them get well. But what if you could find out the actual cause? Surely that would be a better solution?

# 6. Eczema, psoriasis, skin conditions

Asian girlWe all want beautiful skin! It is so connected to our self-image.

But many people suffer poor self-image – all because of a simple food intolerance. But it’s so easy to fix!

Many are surprised to find out that food intolerance can cause skin conditions like eczema and psoriasis.

The inability to fully digest some foods leaves ‘foreign’ particles in your gut – which leak through into the bloodstream. Your body tries to get rid of them by sending them to the skin where inflammation eventually erupts into red itchy patches which may weep with fluid and make skin peel off.

The skin condition psoriasis is linked to gluten intolerance in the medical literature. But moving to the correct diet removes ‘foreign’ things (eliminates the cause) – and allows the skin to heal naturally.

Clear skin is important to anyone – but especially so for children and teenagers who are still developing their sense of self worth and self esteem.
