In this episode, Alyssa Simpson unpacks a common yet widely misunderstood subtype of small intestinal bacterial overgrowth (SIBO): hydrogen sulfide SIBO. Many people with this pattern have spent years chasing answers, trying diets like low FODMAP, gluten-free, or low-carb, cycling through symptom management, and being told tests are normal, only to feel worse, confused, or convinced there’s no solution in sight.

Alyssa breaks down:

• What hydrogen sulfide SIBO is and isn’t
• Why it behaves differently than hydrogen or methane dominant SIBO
• Why symptoms can be unpredictable, systemic, and not limited to the gut
• How conventional testing and treatment often miss it
• How to think about diet, testing, and targeted functional approaches

If you’ve ever felt like your digestive symptoms just don’t make sense, fluctuating between diarrhea, constipation, bloating, brain fog, fatigue, or body pain, this episode will help you finally connect the dots.

Have you tried low FODMAP, gluten-free, dairy-free, or elimination diets and still feel sick after eating? In this episode, Alyssa Simpson breaks down one of the most confusing and misunderstood nutrition strategies in gut health: the low sulfur diet.

This is not an episode about cutting out “bad foods” or following another restrictive diet forever. Instead, Alyssa explains why a short, strategic low-sulfur diet trial can be a powerful clarity tool for people who feel deeply unwell after eating, especially those who have already tried low FODMAP, gluten-free, dairy-free, or elimination diets with little to no relief.

She walks listeners through what sulfur actually is, why the body normally needs it, and why some people suddenly stop tolerating sulfur-rich foods that are otherwise considered healthy. Along the way, Alyssa shares real client stories that reveal how sulfur overload and hydrogen sulfide activity in the gut can explain symptoms that feel random, cyclical, or impossible to predict.

What you’ll learn in this episode:

• When a low-sulfur diet trial makes sense (and when it doesn’t)
• Common high-sulfur foods to temporarily reduce
• Low-sulfur foods that are often easier to tolerate during the trial
• Why protein does not need to be eliminated
• Supplements that may quietly increase sulfur load
• Why improvement during the trial is a clue, not a diagnosis
• How breath testing can help confirm hydrogen sulfide involvement

Eating out with food allergies, celiac disease, IBS, or food sensitivities can feel overwhelming — and sometimes unsafe. In this episode, Alyssa Simpson chats with Dylan McDonnell, founder of Foodini, about how technology and regulation are finally making restaurant dining safer and more transparent.

Dylan shares his personal experience growing up with celiac disease and how it inspired him to create Foodini: a platform that gives diners real ingredient and allergen data so they can confidently choose what’s safe to eat. They discuss why food allergies are rising, why restaurants struggle with allergen accuracy, and how new laws in California could change the future of dining nationwide.

If you’ve ever avoided restaurants because of gut symptoms, food allergies, or fear of cross-contamination, this episode offers clarity, validation, and hope.

Watch to learn:

• Why food allergies and intolerances are becoming more common
• Why restaurant menus are so hard to trust
• How personalized allergen-safe menus work
• What the new California food allergy law means for diners
• How to advocate for safer, more inclusive dining

Guest Bio: Dylan McDonnell is the founder and CEO of Foodini, the dietary intelligence company that helps power personalized menus for the 173m Americans with a food allergy or dietary need. A corporate lawyer by trade, he was diagnosed with celiac disease as a child, and has spent the last number of years advocating for increased transparency regarding what is in the food that we eat.
