As a lover of sweets, but hater of tooth decay, I turned to the imitation sweeteners years ago in my coffee, soda, etc. Always wondering, in the back of my mind........how safe? Some months ago, I heard of a sugar, Allulose, which is NOT artificial, yet carries very little caloric and carb. load with it. But, the only maker of it then had not released it for general sale. Now, I have an article indicating it may be available: I'll be checking it out. Meanwhile, all I know is that it is a "rare sugar", which occurs naturally in some fruits in very tiny quantities. "A rare sugar is a sugar that occurs in very small quantities in nature. Typically they occur in amounts too small to allow for economic separation from their underlying natural source and are typically made through biological processes such as fermentation or enzyme conversion to create the identical compound. Many have interesting characteristics such as having lower calories than traditional sugars such as sucrose, fructose, glucose, or lactose. Specific examples of rare sugars are: Allulose Allose Melezitose" From: https://en.wikipedia.org/wiki/Rare_sugar
Here is a product sheet. Uneconomical to extract it from natural-state, a process was developed to synthesize it starting with fructose, using enzyme technology. Doesn't sound particularly scary, OK'd by FDA. http://www.astraea-allulose.com/product/pdf/MATS007_Technical_Data_Sell_Sheet_CL4.pdf Not clear yet whether it will be sold to other than commercial concerns.
