The asssertions posted here that claim "sweet flavors" triggers insulin response are incorrect. It's been proven time and again that it is the INGESTION (not the stimulation of taste buds) of carbohydrates that triggers the pancreas to release insulin. Do the research and, rather than cite unnamed sources, find a peer-reviewed medical journal, a registered nurse, or a doctor. These information is readily available and you can measure it yourself if you have a physician willing to work with you. Have your doctor take a blood sample prior to drinking a ZERO CALORIE diet soda and then another sample 10 minutes after drinking a glass. Insulin levels will not have changed. Stop posting crap and pseudo-science here.
