Liquid yeast also tends to be darker that light DME. If you really want top brew a very pale beer DME is your best alternative. If you have any qualms about its attenuation simply sub 2 - 5% of the extract with sugar.

I grew up in a small town in IA where flouride was added to the water. At one point, I went 30 years without seeing a dentist. When I went to him, he was astounded that I had no cavities or other problems. And it's pretty much stayed that way. At one point, he suggested having my wisdom teeth removed, then said that I had such great bone mass it would be more trouble than it was worth. Needless to say, it's made me a big proponent of flouridated water.
And which beer did you celebrate with?
Calling it "healthy" would seem to imply yeast health, but I would actually argue that as brewers we don't care about yeast health (unless reculturing) so much as the flavor of the beer. So maybe "appropriate fermentation" would be a better term, which I would define as any fermentation that gives you the results you wanted.
According to Wyeast (sorry for the poor formatting)
Method DO ppm Time
Siphon Spray 4 ppm 0 sec.
Splashing & Shaking 8 ppm 40 sec.
Aquarium Pump w/ stone 8 ppm 5 min
Pure Oxygen w/ stone 0-26ppm 60 sec (12ppm)
It was concluded that pumping compressed air through a stone is not an efficient way to provide adequate levels of DO. Traditional splashing and shaking, although laborious, is fairly efficient at dissolving up to 8 ppm oxygen. To increase levels of oxygen, the carboy headspace can be purged with pure oxygen prior to shaking. The easiest and most effective method remains injecting pure oxygen through a scintered stone.
I wonder just how effective a file size limit would be. For instance, the coconut tree above is under 30K.
