The Claim
In healthy adults with moderate protein intake, vegans exhibit significantly lower urinary sulfate and phosphate excretion compared to omnivores, due to reduced dietary protein intake, resulting in decreased production of acid-producing metabolites derived from animal protein.
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.
Healthy adults who follow a vegan diet and consume moderate amounts of protein excrete less sulfate and phosphate in their urine than omnivores, because their diet contains less animal protein, which produces fewer acid-forming metabolic byproducts.
See the scientific wording
In healthy adults with moderate protein intake, urinary sulfate and phosphate excretion are significantly lower in vegans than in omnivores, primarily due to reduced dietary protein intake, confirming that plant-based diets reduce acid-producing metabolites derived from animal protein.
When people eat less animal protein, their bodies make less sulfur-containing and phosphate-containing waste products. These waste products are filtered by the kidneys and removed in urine. With less of these waste products made, less sulfate and phosphate appear in the urine.
What the research says
1 studyVegans pee out less sulfate and phosphate than meat-eaters, which means their bodies are producing fewer acid-forming waste products — likely because they eat less animal protein. This matches what the claim says.
