The Claim
Increasing sulfur intake from a fixed diet causes a proportional increase in urinary titratable acidity, demonstrating a direct relationship between dietary sulfur and acid excretion.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When people consume more sulfur from their diet, their urine becomes more acidic in direct proportion to the amount of sulfur consumed.
See the scientific wording
Increasing sulfur intake from a fixed diet leads to a proportional increase in urinary titratable acidity, indicating a direct link between dietary sulfur and acid excretion.
When the body breaks down sulfur from food, it produces sulfuric acid. This acid enters the bloodstream and must be removed by the kidneys. The kidneys respond by releasing more acid into the urine, which makes the urine more acidic. The more sulfur a person eats, the more acid is made and the more acidic the urine becomes.
What the research says
1 studyStudy: Vegetarian lifestyle and bone mineral density.
When people ate more sulfur-rich foods like eggs or meat, their urine became more acidic — and the more sulfur they ate, the more acidic their urine got. This matches exactly what the claim says.
