Well, since your note didn't say just what was considered bogus about the product(or why), I was forced to go and find the website myself.
As far as I can tell, there's nothing bogus about the yogurts. There have been lab tests performed by reputable medical professionals (see
http://www.go-diet.com) on yogurt, and it's well-known that the FDA labelling 'set-up' is such that carbs are usually counted, legally, by manufacturers "by difference" AND the carbs in the milk that makes the yogurt are counted BEFORE the bacterial cultures get to work digesting the lactose to make lactic acid (not a carb).
So unless your food scientist has some specific whys and wherefores to justify the "bogus" claim, my researches for the past 3 years on the subject of Low Carb and related issues tell me otherwise...
It IS however, your personal call as to whether you are sensitive to the remaining lactose, and there's only one way to find out.
Me, I make my own yogurt and sweeten it with Splenda, add real fruit like raspberries when I can. Works for me.
Hope this helps some.
PS: you might find a lot of discussion in various forums by doing a search on "yogurt". It's a popular subject.
