Milkfat needed

[jsgt]

Is there any evidence that any of the bacteria or yeasts need fat to stay healthy, i.e. would I lose some of the probiotic benefits of kefir if I started using skim milk?

I don't know of any specific evidence, all I have is anecdotal evidence. When I try low fat, especially non-fat milk, the grains seem to shrivel up more and not do as well. When going back to more fat, they seem to pick up and just seem more rejuvenated. I'm not sure the reason behind it, but to me it seems like the little fat buggers like their fat.

ts digestion is made easier by its relatively low melting point, suitable content of fatty acids, distribution of fat particles and their specifics of absorption in the intestinal tract.
