China just passed the USA in the number of people with diabetis. Drinking a 'COKE' with table sugar or high fructose corn syrup results in higher blood sugars and contributes to diabetis. Many artificial sweeteners like aspertame and sucrolose (Splenda') can do the same for a large part of the population.
Cut back or eliminate these from the diet and reduce obesity and diabetis.
Stevia which grows and is available in Yunnan is a better alternative to sugar or man made sweeteners.
Support Yunnan and use stevia or no sweeteners like hot water.
