A low-sulfur diet is a type of diet where individuals limit their intake of foods high in sulfur. Sulfur is a mineral that is essential for healthy body function, but too much of it can cause health issues such as bad breath, digestive problems, and skin issues. Synonyms for a low-sulfur diet include a low-sulfite diet, low-thiol diet, and a low-sulfur/sulphur amino acid diet. Food items that are typically avoided on a low-sulfur diet include garlic, onions, eggs, broccoli, and cabbage. Overall, a low-sulfur diet can improve health and well-being for people who are sensitive to high sulfur foods.
