That's true. But consider that a living layer of cells (as opposed to a dead ham shank) is engaged in moving fluid in and out (simple diffusion or active transport) in order to maintain homeostasis. So the interface between the cell membrane and the D50 (even though we're only talking a few microns here) will not be 25% glucose. Almost necessarily it will be less, since osmotic forces will favor movement of water from the cells and into the interface. I think the other responders are correct. "D50" will provide a nice glucose and protien rich media for bacterial growth.
Notice that I added that I had no clue how that concept could be stretched to wound care, just that that is probably be the rationale that may be being used.
I made considerable effort to look up information on this topic, and found zip (I did find lots on why sugar paste has been found an effective treatment- that was interesting- sugar paste works on a wound just as with a preservative, draws water; pulls fluid from wound)....so I am thinking that it is not an evidenced based practice, in the least.
