What’s Food Intolerance? 

Food intolerance occurs when our bodies cannot properly digest and convert the foods we eat into the necessary nutrients that fuel our systems.


More simply, food intolerance occurs when you eat something but it fails to be properly broken down in the intestines. The main reason for this failure (maldigestion) is due to a lack of digestive enzymes – it’s their job to break down food molecules so that they can be properly absorbed into the bloodstream.


When the body doesn’t produce enough (or any) of an enzyme that a food requires for proper digestion, the proteins cannot convert into amino acids or nutrients, and will start accumulating in the gut and eventually make their way into the bloodstream improperly.

What Happens Next?

The immune system identifies these partially digested proteins as foreign intruders and attacks them. This attack triggers inflammation in the gut – the immune system’s natural response to injuries and other harmful things that enter the body.


Just like when you have the flu, which also causes inflammation, the body’s fight against the imperfectly digested food will cause many negative symptoms including fatigue, migraine & headaches, eczema, bloating, gas, congestion, weight gain, brain fog, joint ache, acid reflux, food cravings, diarrhea, skin rash and more.


Differently from the flu, however, these symptoms will persist over a lifetime if you continue to consume foods that your body is intolerant to.

Weight Gain, Food Intolerance, and Serotonin Production

One of the more common side-effects of food intolerance is weight gain. This is mainly due to depleted levels of serotonin, the powerful chemical responsible for maintaining mood balance, social behavior, libido, memory, and digestive health. More importantly, though, serotonin also acts as the natural appetite suppressant in our bodies, making us feel satisfied even when our stomachs are not full.


When fighting a food intolerance, serotonin production (95% of which originates from the cells in our intestines) decreases dramatically, leading us to intense carb and sugar cravings.


This process sends our bodies into a vicious cycle of mood swings, depression, and unwanted cravings, all stemming from the body’s fight against food intolerance.

Treating Food Intolerances

The only way to fight food intolerance is to find out which particular foods give your digestive system issues, and eliminate them from your diet.


The traditional way to do this is to implement an exclusion diet. In other words, keep an ongoing food journal, and use it as a reference for when you start feeling any of the common symptoms. Then, once you think you’ve identified the specific food, eliminate it from your diet.


But this involves a lot of guess and check work. Because food intolerance symptoms are usually delayed (in some cases up to 48 hours!), it becomes very difficult to pinpoint the culprit. Often enough, the exclusion diet can lead to a misdiagnosis which then leads to missing out on your favorite foods!  


The more advanced way to identify which foods you’re intolerant towards is to assess your blood in an IgG Microarray Test. This state of the art examination only requires a few drops of blood and delivers precise results.


Beware of less advanced assessments with low reproducibility rates and an inability to discern the difference between temporary and permanent intolerances.
