Zero Tolerance: How Aggressive Testing Crushes Food Sensitivities and Commands Your Diet

Discover how aggressive testing can help identify and eliminate food sensitivities, allowing you to take control of your diet and improve your overall health. Learn how a zero tolerance approach can transform your relationship with food.

In an age where personal health is at the forefront of our minds, understanding our bodies has never been more crucial. Food sensitivities, which differ from food allergies, can cause discomfort and affect the quality of our lives. Identifying these sensitivities is the first step towards managing them and improving our overall well-being. Today, numerous at-home test kits offer a convenient way to discover which foods may be causing you trouble. In this comprehensive guide, we will explore some of the leading brands in the market, each offering a unique approach to food sensitivity testing.


Everlywell has made a name for itself in the realm of at-home lab tests with a practical and user-friendly model. Their food sensitivity test specifically measures your body's immune response to 96 foods, aiming to guide you through a two-part elimination diet.


The test operates on a Class scale ranging from 0-3, with Class 0 indicating normal reactivity and Class 3 indicating high reactivity. A high IgG reactivity level may suggest that certain foods could be causing symptoms, thus becoming prime candidates for elimination from your diet. It's important to note that the Everlywell test is not designed to diagnose food allergies, nor can it determine lactose intolerance or celiac disease.

Quality is a cornerstone of Everlywell's promise, with all partnering laboratories being industry leaders. Rigorous internal and third-party testing ensures a high degree of accuracy, typically between 95-99% results correlation.
