Allulose is a type of sugar substitute that is used to sweeten food or drink without contributing added sugar or calories. It is a rare sugar that naturally occurs in fruits like figs and raisins, and it is also commercially produced from corn or fructose. Allulose is about 70% as sweet as sugar, but it contains only about 10% as many calories. It is considered safe by the FDA and does not increase blood glucose or insulin levels, making it a good alternative for people with certain conditions like diabetes. Allulose is also a good option for people on the ketogenic or “keto” diet, as it doesnt have many carbohydrates. However, it is more expensive than other sweeteners and is not as widely distributed. Allulose is safe to consume, but people who are allergic to any artificial or alternative sweetener should avoid it.
