"The latest data suggests that Allulose is different from other sugars in that it is not metabolized by the human body in the same way as table sugar. Allulose has fewer calories, produces only negligible increases in blood glucose or insulin levels, and does not promote dental decay. As such, we've issued guidance today stating that we intend to exercise enforcement discretion to allow Allulose to be excluded from the total and added sugars declarations on the Nutrition Facts and Supplement Facts labels when Allulose is used as an ingredient."
Managing blood sugar while still enjoying sweet foods is one of the biggest challenges for people with diabetes. Jaca Sugar's pure allulose offers a breakthrough solution: genuine sugar-like sweetness with a glycemic index of zero, plus clinical research suggesting it may actually help improve blood glucose control.
Why Allulose is Diabetic Friendly
Allulose (also known as D-psicose) is a rare sugar that occurs naturally in small amounts in foods like figs, raisins, and wheat. While it tastes and functions remarkably like regular sugar, your body processes it completely differently—making it ideal for people managing diabetes.
The Key Difference: Zero Metabolic Impact
When you eat regular sugar (sucrose or glucose), your body breaks it down and absorbs it into the bloodstream, raising blood glucose levels and requiring insulin to process. Allulose is different:
Your body doesn't convert allulose into glucose
Doesn't trigger the insulin response that regular sugar does
Most is absorbed then passed through your kidneys without being used
Causes no measurable rise in blood sugar
This means people with Type 1 diabetes, Type 2 diabetes, prediabetes, or insulin resistance can enjoy allulose without the blood sugar spikes that make managing diabetes so challenging.
Clinical Research: Allulose and Blood Sugar
Unlike many sweetener marketing claims, allulose's benefits for blood sugar management are backed by rigorous clinical research published in peer-reviewed medical journals.

How Allulose Helps Control Blood Sugar
Research has identified multiple mechanisms by which allulose supports blood glucose regulation. Rather than simply being "neutral," allulose actively works to reduce blood sugar spikes:
Alpha-Glucosidase Inhibition
Allulose inhibits alpha-glucosidase, the intestinal enzyme that breaks down complex carbohydrates into simple sugars for absorption. By slowing this process, allulose reduces the rate at which glucose enters the bloodstream after meals. This is similar to the mechanism of some diabetes medications (like acarbose).
GLP-1 Release
Allulose stimulates the release of GLP-1 (glucagon-like peptide-1) from intestinal L-cells. GLP-1 is the same hormone targeted by popular diabetes and weight management medications like Ozempic and Wegovy. GLP-1 enhances insulin secretion in response to glucose, inhibits glucagon release, slows gastric emptying, and promotes satiety.
Competitive Absorption
Allulose and glucose share the same intestinal transporters (GLUT2 and GLUT5). When allulose is present, it competes with glucose for absorption, effectively slowing the rate at which glucose enters your bloodstream.
Hepatic Glycogen Synthesis
Allulose promotes glycogen synthesis in the liver. Glycogen is the storage form of glucose, so by encouraging the liver to convert blood glucose into glycogen, allulose helps remove excess sugar from circulation.

The GLP-1 Connection: Natural Support Like Modern Medications
One of the most exciting discoveries about allulose is its ability to stimulate GLP-1 release—the same mechanism leveraged by groundbreaking diabetes and weight loss medications like semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro).
GLP-1's Effects Include:
But only in response to glucose (glucose-dependent), reducing hypoglycemia risk
Reducing liver glucose output
Leading to more gradual glucose absorption
Promoting fullness and reducing appetite
Research published in Nature Communications demonstrated that allulose induces GLP-1 release and activates vagal afferent signaling, contributing to improved glucose tolerance. While allulose isn't a medication and shouldn't replace prescribed treatments, it represents a dietary approach that works through similar pathways.
Glycemic Index Comparison: Sweeteners for Diabetics
Not all sweeteners are equal when it comes to blood sugar impact. Here's how common sweeteners compare:
| Sweetener | Glycemic Index | Notes for Diabetics |
|---|---|---|
| Allulose (Jaca) | 0 | Zero impact; may help reduce blood sugar spikes |
| Stevia | 0 | Zero impact; bitter aftertaste for some |
| Monk Fruit | 0 | Zero impact; often mixed with erythritol |
| Erythritol | 0 | Zero impact; cooling sensation; recent cardiovascular concerns |
| Xylitol | 13 | Low impact; can cause digestive issues |
| Maltitol | 35 | Moderate impact; often in "sugar-free" products |
| Coconut Sugar | 54 | Still raises blood sugar significantly |
| Honey | 58 | Raises blood sugar; high in fructose |
| Table Sugar | 65 | Significant blood sugar impact |
| Glucose | 100 | Reference point; maximum glycemic impact |
FDA Labeling: Allulose and Carbohydrate Counting
For diabetics who count carbohydrates, understanding how allulose fits into nutrition calculations is crucial. The FDA has provided specific guidance:
FDA Guidance on Allulose (April 2019)
This means when you see allulose on an ingredient list, you don't need to account for it in your carb counting or bolus calculations the way you would for regular sugar.

Practical Tips for Using Allulose with Diabetes
In Beverages
Allulose dissolves completely in both hot and cold beverages, making it perfect for coffee, tea, smoothies, and more. Start with 1-2 teaspoons per serving and adjust to taste. Remember, allulose is about 70% as sweet as sugar, so you may want slightly more than you'd use of regular sugar.
In Cooking and Baking
Unlike most diabetic-friendly sweeteners, allulose behaves like real sugar in cooking:
Conversion tip: Use about 1.3x the amount of sugar called for. If a recipe calls for 1 cup sugar, use about 1⅓ cups of Jaca allulose.
Monitoring Your Response
While clinical research shows allulose doesn't raise blood sugar in most people, individual responses can vary. When first introducing allulose:
Most people find their blood sugar remains stable or even improves when substituting allulose for regular sugar.

Clinical FAQ: Allulose for Diabetes
Is allulose safe for diabetics?
Yes, allulose is considered safe and beneficial for people with diabetes. It has a glycemic index of zero, meaning it does not raise blood sugar levels. Clinical studies have shown allulose can actually help reduce postprandial (after-meal) blood glucose levels, making it an excellent sweetener choice for diabetes management.
Does allulose raise blood sugar?
No, allulose does not raise blood sugar. Unlike regular sugar which causes blood glucose spikes, allulose passes through the body without being metabolized for energy. Multiple clinical studies, including a systematic review and meta-analysis, have confirmed that allulose does not increase blood glucose levels and may actually help reduce them after meals.
Can diabetics count allulose as sugar or carbs?
No, diabetics do not need to count allulose as sugar or toward total carbohydrates. The FDA has determined that allulose should not be included in total or added sugars on nutrition labels, and it can be subtracted from total carbohydrates when calculating net carbs. This is because allulose is not metabolized like regular carbohydrates.
How does allulose help with blood sugar control?
Allulose helps with blood sugar control through multiple mechanisms: it inhibits alpha-glucosidase enzymes that break down complex carbohydrates, it stimulates GLP-1 release which enhances insulin response, it promotes glycogen synthesis in the liver, and it competes with glucose for intestinal absorption, slowing glucose uptake.
Is allulose better than other sweeteners for diabetics?
Allulose offers unique advantages over other diabetic-friendly sweeteners: it tastes and functions like real sugar, it browns and caramelizes for baking, and clinical research suggests it actively helps lower blood sugar rather than just being neutral. Unlike artificial sweeteners, allulose is a natural rare sugar found in fruits.
Can I use allulose with my diabetes medication?
Allulose is a food ingredient, not a medication, and is generally compatible with diabetes treatments. However, because it may help lower blood sugar, discuss with your healthcare provider—especially if you're on medications that can cause hypoglycemia. Your provider may want to monitor your levels as you incorporate allulose.
How much allulose can a diabetic safely consume?
Research suggests up to 0.4g per kg body weight per single serving and up to 1g per kg body weight per day are well-tolerated. For a 150 lb person, that's about 27g per serving and 68g per day. Most people use far less than this in typical sweetening applications. Start with smaller amounts and adjust based on your personal response.
A Genuine Breakthrough for Diabetics
For decades, people with diabetes have faced an impossible choice: give up sweet foods entirely, or accept blood sugar spikes and their consequences. Artificial sweeteners offered some relief but came with their own concerns about taste, safety, and functionality.
Allulose represents something genuinely new: a real sugar that your body doesn't metabolize, with clinical research showing it may actually help improve blood glucose control. Combined with its ability to taste, cook, and bake like regular sugar, allulose is the breakthrough diabetics have been waiting for.
