More and more studies are out speaking against Diet sodas. They aren't much better, if at all, than regular sodas.
Stay away from any soda.
Myth. Lie.
Diet Soda has no ill effects whatsoever according the the American Cancer Society, National Institute of Health, American Medical Association, Albert Einstein School of Medicine. I could go on, but you get the point.
STOP BELIEVING MYTHS AND LIES. Also, please learn to read between the lines of a study and how to ascertain the concrete points if indeed there are any.
