Aren't Crackers a healthy snack?

Refined carbohydrates are associated with tooth decay and cavities because when starches from white flour linger in the mouth for a long time, they break down into simple sugars.  Bacteria in the mouth feeds on these sugars and produces acids, which in turn -- causes tooth decay.  

The same mechanisms that make starchy foods rapidly digestible by humans also make them rapidly digestible by microorganisms in dental plaque.  Thus, the Glycemic index of foods is relevant to the risk of chronic diseases such as type 2 diabetes, cardiovascular disease and also DENTAL CARIES!
