Solution: First, make sure cheese is actually the cause of your rotten-egg farts. Eliminate all dairy completely for just a week (you'll survive!), and take note of how you feel once it's slowly reintroduced. If the hot, smelly farts come back, pair your favorite dairy-rich foods with a lactase supplement. Taking it with the first bite should ward off the gas, Dr. Caguiat says.
You have a secret food allergy
Remember when you made fun of people without celiac disease who claimed they were gluten intolerant? Turns out, that might actually be a thing. A study from the National Institutes of Health showed that non-celiac, gluten-sensitive people (NCGS) exhibited nasty symptoms after eating gluten, including bloating and constant farts, compared to the placebo group. Another gas catalyst could be fructose, the natural sugar found in fruit, especially if you have fructose malabsorption (similar to lactose intolerance). Like lactose, fructose is a sugar that can't be digested, and they both come out as room-clearing gas.
Solution: Try a low-FODMAP (short-chain carbohydrates and sugar alcohols that aren't easily absorbed) diet, which is an elimination diet that cuts out most cruciferous vegetables, legumes, high-fructose fruits, processed meats, wheat, and gluten. It sounds like Whole30 on crack, but it may help identify what’s causing those nonstop farts. Otherwise, visit your gastroenterologist for further testing, and raid the local pharmacy for over-the-counter supplements, such as Gas-X, Beano, or a carminative.
