I read an interesting little article in the MX Mag that you can get at the train station on the way home, it went like this:
A SWEET WAY TO GET FAT
Splenda, the sweetener used as a sugar replacement, has been linked to weight gain by a study.
It also said it could dampen the effect of some medicines.
The sweetener, which is known generically as sucraiose and made from sugar, is the preferred sugar alternative of millions of dieters while used by top brands to create diet versions of popular products
But US researchers who fed rats different doses of Splenda found the rodents put on more weight than those not fed it.
So don't really know what to make of this, it doesn't state the study name or have a link to where you could locate it to check the facts, another thing that made me think of the results as being deceptive is that it also doesn't state whether the rats were feed NO sugar alternative, sugar or nothing, which of course would lead to the rats gaining weight as apposed to a rat who didn't consume any sugar.
