@MsCris mentioned allulose a naturally, but fairly rare, sugar in figs, maple syrup and others. It has the exact same chemical formula as fructose, glucose and galactose with a different molecular structure - the way the carbon, hydrogen and oxygen atoms are bonded. In the paper I read allulose is transported into the bloodstream by the same transporter as glucose, GLUT5. Fructose has to be metabolized by the liver but allulose is not. Most 98% of allulose is excreted in urine with a tiny bit in feces. There seems to be several benefits for those with diabetes mellitus in consuming allulose besides being a non-caloric sweetener. It appears to have health benefits as well, such as, increasing insulin sensitivity, anti-hypo and hyperglycemic, anti- hyperlipidemic, and enhancing antioxidants. This sugar sounds almost like a miracle. I guess we will see, as there are fairly inexpensive ways to synthesize allulose. Link to the original thread where allulose was brought up. > [@Keto bars that actually taste good (and are actually keto)?](https://forum.fudiabetes.org/t/keto-bars-that-actually-taste-good-and-are-actually-keto/13691): > > Anyone find a keto bar (pre-made, wrapped and ready to go) that actually tastes good? The Atkins ones taste the best IMHO, but upset my stomach and their calculations don’t make sense, so I never know what to bolus. Quest are too tough unless I microwave them, but that trumps the convenience factor. I have tried so many and don’t really like any of them, but have a few I buy just to be able to grab something quickly if needed. Link to the paper I read - [https://www.frontiersin.org/articles/10.3389/fbioe.2020.00026/full](https://www.frontiersin.org/articles/10.3389/fbioe.2020.00026/full) Link to the molecular structure of allulose AKA D-Psicose - [D-Psicose - American Chemical Society](https://www.acs.org/molecule-of-the-week/archive/p/d-psicose.html) This link is to some products that contain allulose, I am not recommending any as I have not used any of these myself. If it wasn’t for @MsCris I may never have heard of this sugar before. - [https://www.bestalluloseproducts.com/https://www.bestalluloseproducts.com/](https://www.bestalluloseproducts.com/https://www.bestalluloseproducts.com/) ---

@CarlosLuis I have used allulose successfully for cake products (I use monk fruit to add extra sweetness, since allulose is less sweet than sucrose), I add to coffee/tea, almond milk puddings, and I make a simple syrup (for cocktails, like mojitos). Allulose is not as good for true caramelizing, or crispy/crunchy non-grain cookies. Disappointing results. Note: I find that once a serving of the food contains more than 25g of allulose, I start to experience a mild, overnight laxative effect. But it’s nothing like the pain and explosiveness of what sugar alcohols do to me! (Sorry if TMI) Some ready-made products to try: Sweet Logic cake and mug cake mixes. Munk Pack nut and seed bars. LivLo maple-flavored SyrLo syrup. Wholesum Yum Simple Syrup. Enjoy!
