Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
A worldwide systematic review, meta-analysis and meta-regression of nitrate and nitrite in vegetables and fruits.
The study found that countries with better food safety systems, like Poland and Portugal, have much lower levels of harmful chemicals in their fruits and vegetables, which supports the idea that good food safety rules help keep produce cleaner.
