I have to agree with Popologist on this one. Just because it is man made does not mean it is bad for you.
IMO the man made ingredients can substitute for the flavor or sweetner while not having the negative impact on the body. For instance, when a pure cane sugar drink is ingested the body will be triggered to raise insulin levels and start to store the carbohydrates as fuel for later,,,,hence, fat accumaulation. When an artifical sweetner is used the mechanism that triggers responses on receptor sites are essentally void so no reaction takes place, therefore no fat accumulation.
With that being said there are exceptions, some artificial sweeteners, known as sugar alcohols, can allow for the same process to occur or not occur but will wreak havoc on the digestive system beause these will be attempted to be broken down as regular carbohydrates and absorbed through the intestines but the body will not be able to do so resulting in severe cramping. Uusally the sugar alcohols are found in low sugar or no sugar candies and just a few drinks.
Whether you think can or think you can\'t, you\'re probably right!
