Claim: As soon as people can afford it, they polish rice to remove the toxic outer layer and consume the inner part.
Verdict: Partially True (60% confidence)
Explanation: According to the study published on PMC (Tier 1), rice polishing is an important method to reduce the concentrations of heavy metals like lead and cadmium, supporting the claim that polishing rice removes toxins. However, no source directly confirms the timing or economic aspect of when people choose to polish rice, such as doing so 'as soon as they can afford it.' This absence of evidence on the timing and economic decision prevents a fully correct verdict.
