PoshanSenseResearch papers are a lot to chew. We unpack the findings, keep the caveats, and bring the conversation back to everyday food.

Nitrate-rich beetroot juice has a plausible mechanism, but a biomarker change is not a faster workout. Canadian and US trials show why context matters.
Take a bite →These are educational explainers, drafted with AI assistance and checked against linked sources. They are not clinically reviewed. We combine complementary studies from 2010 onward to answer useful everyday questions. Publication date and data-collection date are different: recent papers can analyse older data. We include uncertain and null findings, not just exciting positive results.
