Sure, the milk powder adds more carbs, but good bacteria does not discriminate. Meaning, whatever carbs/milk sugars are in there - the good bacteria will eat them up - and eat more of them up the longer the yogurt is incubated.

I incubate it myself - always many hours past the required 24, and it is EXTRA TART when done, I figure the good bacteria just kept eating and eating whatever carbs/lactose was present until it was almost gone. Whatever carbs/milksugars are added are eaten up, especially if incubated for gosh, sometimes two days or longer.

It's my reasoning. I've been eating my yogurt regularly for a year - and alot of it. I haven't stalled, gained or plateaud. It's a wonderful high calcium food - and you can ADD fiber to it if you like (flaxseed) for example or psyllium. The article also complained that it had no fiber - so what? Add your own!

Enjoy!
