Grain of salt and all that, but this is in line with what I’ve thought for years:
A Columbia University study also found no reduction in common infections among inner-city families given free antibacterial hand soap, detergent, and cleaning supplies. The same year, University of Michigan epidemiologist Allison Aiello summarized data on hand hygiene for the FDA and pointed out that three out of four studies showed that alcohol-based hand sanitizers didn’t prevent respiratory infections.
One issue: they could (should) have been most explicit on the differences between hand washing, which I like, and hand sanitizers, which I loathe.
This article, unlike most newspaper reports of study data, wonders aloud about the data’s applicability. In fact, Tierney’s entire point is that maybe scientist haven’t wondered enough about the dietary reality of salt consumption.
“When you reduce salt,” Dr. Alderman said, “you reduce blood pressure, but there can also be other adverse and unintended consequences. As more data have accumulated, it’s less and less supportive of the case for salt reduction, but the advocates seem more determined than ever to change policy.”
