What does your poop say about your diet?
Urine metabolomics unravel the effects of short-term dietary interventions on oxidative stress and inflammation: a randomized controlled crossover trial

Surprising Findings
The Balanced Korean Diet increased austalide G—a rare fermented soy metabolite—in urine, but no corresponding drop in blood inflammation markers occurred.
Most studies assume plant-rich diets reduce inflammation via biomarkers like CRP—this study proves that metabolic changes can happen without measurable blood-level effects.
Practical Takeaways
Add fermented soy (like doenjang or tempeh) and colorful vegetables to your meals to boost beneficial urinary metabolites like benzoic acid and austalide G.

Eating a Korean-style diet or following U.S. dietary guidelines for four weeks can boost certain healthy plant compounds in your food, but that doesn’t seem to reliably lower inflammation or oxidative stress in your blood.
Scientists found that the chemicals in urine change depending on what you eat for a short time. If you eat a traditional Korean diet, your urine shows more of certain healthy compounds from soy and fats, but if you eat a typical Western diet, you see more different chemicals from proteins and steroids.
People who eat the typical American diet tend to have more of certain chemicals in their urine that come from eating meat and fats, and these chemicals suggest their bodies are under more stress from burning fuel.
People in Korea who are overweight and eat a traditional diet full of veggies, soy, and plants pee out more of certain natural compounds than people eating typical American junk food — this might mean their bodies are handling food differently.
Eating healthy, nutrient-rich foods for a short time can lower a blood marker that shows your body is inflamed.
