- Researchers studied the impact of diet on intestinal Sulfate Reducing Bacteria. This pilot crossover study monitored the gut bacteria of four healthy individuals, who followed two interventional diets for 10-14 days, containing high or low sulfur-containing amino acids (SAA). No major changes occurred in the quantity of Sulfate Reducing Bacteria, suggesting that "dietary interventions alone may be insufficient for rapid therapeutic targeting of Sulfate Reducing Bacteria."
