Washing rice before cooking and using lots of water (like boiling it like pasta) removes more harmful metals like arsenic and lead than just cooking it in a small amount of water — so rinsed cooking is better at making rice safer to eat.

Appropriate Language Strength
association

Assessment Explanation
The claim presents precise percentage reductions, suggesting it is based on controlled experimental data comparing two cooking methods. However, the use of 'associated with' is appropriate because the claim does not prove causation — other factors (e.g., rice variety, water source, soil contamination) could influence metal levels. The percentages are specific, which implies quantitative measurement, but without citation, the precision may be overstated if derived from a small or non-representative sample. The verb 'reduces' is acceptable in context of observed effect, but 'associated with' better reflects observational or comparative study limitations.
More Accurate Statement
“Rinsed cooking of rice is associated with greater reductions in arsenic (42.3% vs. 26.9%), lead (42.9% vs. 26.9%), and cadmium (27.6% vs. 20.9%) compared to conventional Kateh cooking, based on controlled experimental comparisons.”

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)
The study found that washing rice and cooking it in lots of water removes more bad stuff like arsenic and lead than the usual way of cooking rice — exactly what the claim says.
