It’s all well and good to go about your life and enjoy food, but what if you have a food intolerance? What if you are trying to figure out what you can avoid and what you should eat? A lot of us don’t have a clear understanding of what an intolerance is and that means that we aren’t able to really work with it the same way that we could be with the right information. Are you ready to define food intolerance and learn how to adapt your life as a result?

How to define food intolerance

When we take a look at our bodies and how to define food intolerance, the issue itself may feel different for each person. It makes sense when you think about it. We’re all unique individuals and our bodies react differently to foods, and even illnesses or infections. Food intolerance could be the same. So, let’s take a step back and take a look at it from a clinical, formal point of view.

Research tells us that food intolerance is caused by the effects of food ingredients that don’t agree with our systems; they could be caused by a sensitivity or a deficiency in transportation or enzymes within our bodies [3]. It’s also thought that somewhere between 15%-20% of the general population has a food intolerance, knowingly or otherwise [1]. That being said, both men and women can have similar symptoms:

Indigestion and discomfort: From bloating to flatulence to discomfort in your stomach area, the most common symptom is thought to be general discomfort and even a few bouts of diarrhoea.

Congestion and illness: Feeling congested and ill seemingly out of nowhere is another symptom that you are dealing with a food intolerance. Inflammation needed to digest and process the food can create congestion that comes up in the form of a sinus headache, a stuffy or running nose or even a slight wet cough.

Fatigue and aching muscles or joints: Feeling exhausted as well as full of aches and pains when you were fine otherwise is another common complaint. A lot of times these can be hard to link to food intolerances because they’re so easily explained away by other problems and struggles that you are dealing with.

Another note about symptoms is that they can take place 30 minutes to an hour after you eat the problem food, or they could even pop up a day or two later. Proper identification and connection can be hard unless you specifically know what you’re looking for. On that note…

The importance of food intolerance testing

Knowing your enemy is key to defeating it and food intolerance testing is no exception. Research agrees that diagnosing food intolerances can be tricky and it’s important to rely on formal, structured diagnostic procedures in order to get the right confirmed results to make the difference [1].

So, now that you can define food intolerance your way and understand how surprisingly complex its science can be, consider reaching out and getting a carefully refined professional food intolerance test today. It’ll give you the freedom you didn’t know you were missing.
