Is diet pop worse for you than regular pop?!

Is diet pop worse for you than regular pop?

I have been hearing this, but I do not understand how.....please let me know if it is true or not, and if it is why?

Yes, actually it is, our bodies digest sugar naturally. And on varying degrees, our bodies cannot break down "sugar free" sweeteners. Much like Olean, the oil used in potato chips a few years back, only without the visible side effects. Saccharin is the obvious villain that killed lab rats during testing. But HOW was overlooked... These sweeteners in the bloodstream are very small particles and get all of the way to synapses in the brain and nervous system, blocking the impulses contributing to strokes and seizures. But the news is that all of these sweeteners are the culprits. Just to varying degrees. Lab rats were/are used because of their higher metabolic rate and similar body systems. To think that anything you put into your body could just magically disappear is ridiculous, that is what producers would like us to believe. This new _____ is sweeter than sugar, with no calories!! There are no calories because our bodies can't break down the materials it's comprised of. None of this information has come to pass yet because of the "newness" of diet sweeteners. Not new you say? In the large scheme of things, how much of these sweeteners do we digest daily, and how do our bodies compare with those of lab rats who I believe were on a strict "diet"?
