The favorable chemical reaction occurs locally meaning that even with fluoridated water the only time it's benefiting your teeth is while the water is still in your mouth, touching your teeth, before you swallow.

Definately! Research (NIH, ADA) indicates the benefit from flouride is only from topical application. Use a good flouridated toothpaste and mouthwash. We don't need to be swallowing it.

Distilled or deionized water isn't dangerous or acidic like some folks think. It is completely neutral, lacking any buffering by salts or solutes. For this reason, taking a pH measurement of this water means nothing, as pH of pure water is not relevant! Would be happy If others with science background can pitch in. I'm a biochemist. Many bottled water brands are zero TDS (or close to that), means 'total dissolved solids' in mg/kg or ppm.

I am having a terrible time getting Costco to give me a list of Kirkland brand products that are gluten-free!! I love Costco, but they are being very difficult. They will only tell me by specific product, they won't provide a list. i am almost ready to dump my membership!!

I agree with the previous posters. Costco doesn't mfr them, and the product's ingredients can change, so it may be difficult to keep an updated gluten-free master list. Also, what they stock varies with store location and with time. My wife always tells me "if you see something at costco you want, just buy it as it may not be there next week."
