However, as with any sugar substitute, there may be concerns about its safety and health effects with prolonged use. This article takes a closer look at Allulose Keto and whether to include it in your diet.
What is Allulose?
Allulose is also known as D-psicosis. It is classified as a “rare sugar” because it is only found naturally in certain foods. Wheat, figs, and raisins contain it. Like glucose and fructose, allulose is a monosaccharide or a single sugar. In contrast, table sugar, also known as sucrose, is a disaccharide made up of glucose and fructose combined.
In fact, allulose has the same chemical formula as fructose, but differently. This difference in structure prevents your body from processing allulose in the same way as fructose. Although 70–84% of the allulose you consume is absorbed into the bloodstream from the digestive tract, it is excreted in the urine without being used for fuel.
It has been shown to resist fermentation by gut bacteria, minimizing the chances of bloating, gas, or other digestive problems. And here’s the good news for people with diabetes or blood sugar monitoring – it doesn’t raise blood sugar or insulin levels.
Allulose also contains only 0.2–0.4 calories per gram, or about 1/10 of the calories of table sugar. Additionally, early research suggests that allulose has anti-inflammatory properties and may help prevent obesity and reduce the risk of chronic disease. Although some foods contain small amounts of this rare sugar, in recent years, manufacturers have used enzymes to convert fructose from corn and other plants to allulose.
The flavor and texture have been described as being identical to table sugar. It’s about 70% as sweet as sugar, which is similar to the sweetness of erythritol, another popular sweetener.
May Help Control Lowers Blood Sugar Levels
Allulose can prove to be a powerful diabetes control agent. Indeed, a number of animal studies have shown that it lowers blood sugar, increases insulin sensitivity and reduces the risk of type 2 diabetes by protecting the insulin-producing beta cells of the pancreas.
In a study comparing obese rats given allulose to rats given water or glucose, the group receiving allulose showed improved beta cell function, a better response to blood sugar, and less increase in belly fat than the other groups. Early research also suggests that allulose may have beneficial effects on blood sugar regulation in humans.
In a controlled study, 20 healthy young adults were given either 5–7.5 grams of allulose with 75 grams of sugar maltodextrin, or maltodextrin alone. The group that took allulose experienced significantly lower blood sugar and insulin levels compared to the group that took maltodextrin alone.
In another study, 26 adults ate food alone or with 5 grams of allulose. Some people were healthy, others had prediabetes. After eating, their blood sugar was measured every 30 minutes for two hours. The researchers found that participants who took allulose had significantly lower blood sugar levels after 30 and 60 minutes. Although these studies are small and more research is needed in people with diabetes and prediabetes, the data to date are encouraging.
Allulose Can Speed Up Fat Burning
Studies in obese rats show that allulose can also help burn fat. This includes unhealthy belly fat, also known as visceral fat, which is closely linked to heart disease and other health problems.
In one study, obese rats were fed a normal or high-fat diet that contained allulose, sucrose, or erythritol supplements for eight weeks. It is important to note that, like allulose, erythritol contains virtually no calories and does not raise blood sugar or insulin levels. However, allulose had more benefits than erythritol. The allulose-fed rats gained less belly fat than the erythritol or sucrose-fed rats.
In another study, rats were fed a high sugar diet with either 5% cellulose fiber or 5% allulose. The allulose-fed group burned significantly more calories and fat per night and gained much less fat than the cellulose-fed rats.
