Sneaky Signs and Symptoms of a Food Sensitivity

I weighed in about food sensitivities in this article for Shape Magazine:

Histamines are chemicals found in the body’s cells, as well as in certain foods. When you’re sensitive to a specific food or drink, histamines and other chemicals are released into the bloodstream and trigger an immune response, says New York–based registered dietitian Maya Feller, R.D. In a healthy person, histamines are broken down by an enzyme—diamine oxidase, or DAO—and if your body’s low on this enzyme or is sensitive to histamine-rich foods (or both), the overload of histamines can lead to pesky symptoms like anxiety and dizziness (as well as fatigue and mood swings, FYI).
