Food intolerances are more common than food allergies. The symptoms of food intolerance tend to appear more slowly, often many hours after eating the problem food, even up to 3 days later. Typical symptoms include bloating, constipation, diarrhoea, smelly gas and stomach cramps. It’s possible to be intolerant to several different foods, which can make it difficult to identify what’s actually causing the problem. Plus it may not just be the food either but your lifestyle.

What is the difference between allergy vs intolerance

 Population studies in the UK suggest that between 1 and 2 people in 100 (1-2%) have a food allergy, whereas as many as 30 in 100 (20-30%) believe themselves to be intolerant to one or more foods [1].

A true food allergy causes an immune system reaction that affects numerous organs in the body. In some cases, an allergic food reaction can be severe or life threatening and it happens almost immediately.

Food intolerances or sensitivities however are generally less serious and often limited to digestive problems.

I found that the top causes of why people become intolerant to foods in the first place are as follows:

  • Food poisoning. Getting severely ill can damage our immune systems. As 70% of our body’s immune system is located in our gut we can certainly make a link to this and intolerances.
  • Antibiotics. Taking a bought of antibiotics for a period of time can wreak havoc on our gut microbiome. From the PLOS Biology journal: Antibiotics actually influence the abundance of the bacteria in the gut, decreasing the richness, diversity and consistency of them [2]
  • New Country. Now this could be a change in diet or it can be from getting ill abroad, both has shown from my experience that it will negatively impact your health start you on the road to having intolerances.
  • Pregnancy. Did you know that during the first and third trimester of pregnancy the diversity of gut bacteria reduces and then there is an increase a strain of bad bacteria [3]? All of this can impact the immune system.
  • Recurring stress or psychological factors.One of the biggest factors in today’s era is Stress whether it’s work, a loss, finance, family and even over exercising. Sometimes we don’t even know when we are stressed. It can damage our gut lining thus causing intolerances.

I found this comment on the Food Standards Agency website –

Food allergies or intolerances can be cured

FALSE: There is currently no cure for food allergies or intolerances. The only way to prevent a reaction is to avoid the food you are sensitive to [4].

I disagree when it comes to the intolerances! I was intolerant to eggs, dairy (cows milk), yeast, lentils and peaches according to my intolerance test however today I can eat them all. I have added the image of my actual results from the intolerance test.

Yes, within moderation but that is like any food – we need to eat in moderation otherwise you could become sensitive to that food type as well so variety is also the key to not only prevent an intolerance but also help repair the gut to remove the intolerance.

If you have food intolerances, there are steps to aid digestion of certain foods or to treat the underlying condition causing your reaction. If you want to know more then you can find me at or book a FREE Gut Health Breakthrough session with me HERE.
