As a dietitian specializing in gut health, I often have clients come in with results from food sensitivity tests—usually accompanied by a mix of relief and overwhelm. It’s understandable; they’re seeking solutions for persistent gut issues or looking to uncover hidden food sensitivities. But while they’ve finally got data, the list of “avoid” foods is often long and daunting. I hear things like, “I love this food, and now I’m not supposed to eat it!” or, “I’ve eaten this my whole life without issues—how could it suddenly be a problem?”
With the surge in at-home health tests, food sensitivity testing can seem like an easy next step, especially if you’re experiencing digestive issues, fatigue, or other symptoms that make you think, Could it be something I’m eating? Many of these direct-to-consumer (DTC) tests promise clear answers, but the science behind them tells a more nuanced story.
If you’re curious whether food sensitivity testing is worth exploring, this newsletter will dive into the research, sharing insights from my experience and what other trusted experts have to say.
