Brain Fog & Food Allergy Relationship | Allergy Test

We all get that feeling from time to time, where you can’t quite seem to focus on the task at hand. So you try switching to a different job on the list, to no avail. You’re probably suffering what is commonly referred to as ‘Brain Fog’

Several things are believed to be a cause of ‘Brain Fog’;


Depression is believed to be the most common cause of brain fog, but what causes depression. This is incredibly difficult to define as stress is very much an individual experience, personal to whoever is experiencing it. Money problems, strained relationships, even an allergy can contribute to depression. If you think you’re experiencing depression, you should seek support.

Lack Of Quality Sleep

Quality sleep is vital to your mental health, and failure to get the requisite amount of sleep to allow your body and mind to recover can be a cause of stress. To address this, you should start by making sure you go to sleep and wake up the same time every day (even on weekends), avoid looking at blue screen devices in the hour before sleep and take an allergy test to see whether any foods may be interrupting your sleep.


An unhealthy body makes for an unhealthy mind. If you’re not meeting your vitamin and mineral requirements, then you deny your brain the vital tools it needs to operate optimally. Vitamin b-12 deficiency, for example, will cause brain fog. You may also have an allergy or food intolerance that causes brain fog.

Medical Conditions

Several medical conditions can cause brain fog. These include: 

  • Diabetes
  • Depression
  • Migraines
  • Hypothyroidism
  • Multiple Sclerosis
  • Dehydration

If you suspect you have any of the above conditions, you should seek medical advice.


You can take the first step towards clearing the fog with an allergy test. Find the foods or substances that could be coming between you and the mental clarity you’re looking for.
