Gluten Associated Sensitivity and Cross-Reactive Foods | Cyrex Array #4

Is your body reacting to gluten-free foods as if they were gluten?

Gluten intolerance and sensitivities are not as straightforward as you might think. In fact, researchers found that some people react to other foods (even gluten-free foods) as if they were gluten. If you tested positive for gluten after using the Cyrex Labs Gluten Intolerance Test, you may be embarking on a gluten-free lifestyle. In order to achieve your gluten-free health goals and create optimal health, it is important to know what other goods cause your body to react.

Lactose Intolerance and Coffee Intolerance

The most common example of this type of cross-reaction is the fact that about 50% of those who are gluten intolerant are also sensitive to dairy. Surprisingly, researchers have also found that coffee tends to cross-react with gluten. If you are leading a gluten-free lifestyle, this test will tell you whether or not you need to eliminate coffee from your diet.

Gluten-Free Lifestyle

Because there are gluten-free foods that the body will recognize as gluten, it makes it difficult to tailor lifestyle changes. With the information from Cyrex Labs (Array #4), this test can help pinpoint those foods that cross-react to gluten.

comments: Your customer service is excellent - responsive and goes the extra mile. Worked with Rachel, who was terrific. The website lagged a lot, but may be new year's eve traffic. Also, a coupon supposed to expire on 1/1/22 did not work when ordered on 12/31/21. Overall however, your service and availability of labs, which is most important, is excellent.
