Every year, 12 million Americans have negative reactions to the food they eat – of which, 30,000 of them will have to see medical attention some reactions are food ALLERGIES like nut or fish allergies and they are pretty easy to diagnose. Food SENSITIVITIES, on the other hand, are much more complicated and often go undiagnosed. Food sensitivities can lead to chronic conditions such as migraines, eczema, arthritis, obesity, weight gain, Crohn's disease and irritable bowel syndrome (IBS), depression and chronic fatigue. Symptoms can occur several hours, or even days after exposure making it extremely difficult to pinpoint the cause. The delay between exposure and symptoms makes the Alcat Test an invaluable tool to identify reactive foods and substances.
