WOW, is right, what was in that protein shake (besides the sucralose?)? I agree (a sugar lobbyist will bash the hell out of splenda), but the same is to be said of all these supplements. If you manufacture a weight loss supplement, you can also find/manipulate studies supporting your "revolutionary fat-loss formula."
Dr. Mercola is definitely on the extreme side, but that doesn't mean I throw everything he says completely out the window. Many of his recommendations are unrealistic and unaffordable. He does, however, in his radical view, mange to address some valid issues. A college professor of mine would also say not to "believe" everything I google. She would say be "critical, not cynical." Just because I asked a question doesn't mean I use google as the gold standard for research.
If you read the original post, I wasn't trying to attack splenda, the question itself was merely "food" for thought. I never said it was crap, etc. I thought working out was supposed to decrease stress, but some of us still manage to get a little to worked up. Maybe sucralose doesn't raise insulin levels, rather it causes us to jump all over people's opinion.
As far as using Grow! is concerned, I highly doubt the sucralose will have much effect on highly active, clean-dieting, fitness/nutritionally educated individuals. It's more significant to those who abuse these artificial sweetners and drink 3+ of such MRP with their 3+ diet cokes per day.
