Food intolerance testing at home for a fraction of the cost
We all know some foods just rub us up the wrong way but sometimes we find it hard to know which ones and without expensive tests can feel stuck. Food intolerance can be a very difficult thing to get a grasp on and for some it may be a much larger issue that still needs to be addressed such as leaky gut but for know we will talk about why food intolerances occur and how to measure them at home virtually for free.
Food intolerance is all starts with some form of damage or stress to the intestinal wall, certain stress hormones, as well as certain foods repeatedly exposed to the intestinal wall, will cause an increase in the size of particles that can get through, a term called leaky gut. Once through into our bloodstream our adaptive immune system kicks in, large particles are recognised as antigens basically our immune system does not recognise them as part of us (they do not have the self-antigens attached). Any large particle can be recognised as a foreign antigen including proteins, nucleic acids, many large carbohydrates and even some large lipids. Of these, the ones that cause the most violent reaction are pollens, grains and micro-organisms such as bacteria, the first time they enter and are picked up by the adaptive immune system they are recorded and stored.
Once the body encounters something it stores that information for the future as to amount faster and stronger defences when the time comes again, the more times large particles of food breach the intestines the larger chance this is to happen and the larger the response is likely to be.
This is the basis for immunity from disease and even when the gut lining is healed we may still end up having immune responses to certain foods as they pass the Peyer's patches in the intestines which are a special immune satellite station that could cause a repertory immune event.
So how can we tell if a meal caused us stress?
Simple blood glucose measurements before and 1 hour after your meal can provide you with a good gauge to objectively see if a food item is consistently causing a stress reaction. While many things can cause a stress response you can use a trial and error approach that gives you real objective feedback instead of subjective feelings. Be aware that food, location, fluid intake, amount of food, activity and emotional status can all cause stress responses and should be accounted for.
A normal response after a meal is for blood glucose to rise by 1.0 mmol/L or by 18 ml/dL every person will need to understand there own baseline first, levels can go up a little, a lot, stay the same or even drop after a meal some times this can hard to understand but that in the scope of this post, the key aspect to understand is if you have a sharp increase that it is probably due to some form of stress such as eating too much, having an argument or eating a food that causes an immune response.
