Consuming one serving of canned soup per day for only five days leads to a 1000% increase in urinary BPA levels.

This figure comes from an observational study conducted by Carwile et al. (2011), published in JAMA, which indeed showed a significant correlation between canned soup consumption and BPA excretion. The mechanism is well-documented: bisphenol A (BPA) is often used in the epoxy resins of interior can linings and can migrate into food. The massive increase in urinary levels is an observed fact in this specific study, reflecting real and measurable exposure. However, it is important to note that this is a short-term intervention study on a small group, not proof of direct clinical toxicity at these levels for the general public. Extrapolation regarding long-term health risks remains a subject of active scientific debate, as safety thresholds are constantly being reassessed by health agencies (such as the EFSA). The advice is therefore factually supported by research regarding exposure, while remaining an observation on accumulation rather than a demonstration of immediate harm.
