If it is actually a health code, it's hard not to conclude that it's fallen out of date in its enforcement and interpretation.
It's really hard to see why in the world coffee and tea would be prohibited while other substances are A-OK. It seems pretty evident that the word of wisdom leaned pretty heavily upon, or was completely lifted from, Sylvester Graham and his ideas about "the heating of the blood." We can compare nutritional data between those substances and others now, and the hot drinks thing seems antiquated. The idea that they can keep you out of an LDS temple, while essentially trashing your body on other "approved "substances, or eating all the meat you want, makes no sense. With the obesity epidemic here in the states, it's fairly apparent that there are bigger issues to confront in treating one's body as a temple than the explicitly banned coffee and tea.
For the record, other than a very rare Starbucks run for a seasonal beverage, I don't indulge in any prohibited word of wisdom substance. But I'd like our health code to at least make sense. We revamped the interpretation at least once. It certainly wouldn't bother me if we did so again. A redirect on how we address our own health might be beneficial to the Saints.
