When Your Body Feels Toxic After Eating: The Sulfur Clue Everyone Misses

Send us Fan Mail

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
