It's very important when it comes to food allergies that you be honest with yourself. Ignoring even the slightest seemingly insignificant reaction could be an import warning from your body, that bigger more severe issues are right around the corner. I found this out the hard way with my own allergies (Soy and Dairy), and paid for it later in life. For years I was getting allot of wax buildup in my ears, and experiencing great pain deep within either ear, if I tried to sleep on my side. I was also having the typical gastrointestinal issues that one usually experiences when they have a dairy intolerance, but just like the ear issue I was ignoring the warning signs.
When the body doesn't digest food properly, especially on a regular basis, the lining of your intestines becomes compromised, and because the condition of your intestines is a direct indicator of the condition of your immune system the damage being done can have severe consequences. A weekend immune system opens the door to a world of problems, creating the perfect environment for unwanted bacteria and parasites to flourish making you susceptible to any number of viruses or diseases.
So be smart and listen to what your body is telling you, because you’re only fooling yourself.
