Rare sugars: what are they and what can they do for you?

|

Obesity, diabetes, and metabolic syndrome have become major public health problems with global relevance. To curb this unfortunate epidemiological landscape, balancing energy consumed and expended has become crucial, impelling the industry to innovate and renovate, by reducing sugar, calorie and portion sizes of their food and beverages.1-3

Allulose sugar reduction treats

Leading health organizations, such as the American Heart Association (AHA), the American Diabetes Association (ADA) and the Academy of Nutrition and Dietetics (AND) acknowledge the value of low- and no-calorie sweeteners (LNCS) to reduce calorie intake as part of an overall healthy diet and physical activity regimen.4,5 This position is based on robust scientific support that has linked LNCS intake to improved weight management6-8, favourable glycaemic response9-13, and better overall health14,15. The European Food Safety Authority (EFSA) published a position paper in 2011 concluding that LNCS’s benefits include glycaemic control and oral health.16

Today, new innovative sweetening ingredients are increasingly available to help reduce calories in foods and beverages and are now more frequently found on food labels in countries such as the United States and Mexico. This is the case of the so-called “rare sugars”, new sugar alternatives that provide few, if any, calories, while delivering the same functionalities of sugar, with the potential not only to meet the expectations of but pleasantly surprise the most demanding consumer.

Among rare sugars, allulose stands out. It is a low-calorie sweetening and offers the taste and texture of sugar without all the calories. Allulose can be naturally found in figs, raisins, molasses, maple syrup and can be produced from various sources of carbohydrates (corn, beet and sugar cane). In the US and Mexico allulose is exempt from Total Sugars and Added Sugars on the Nutrition Facts Panel.

Allulose has 70% of the sweet taste of sugar, and unlike LNCS which often need to be used in extremely limited amounts and therefore do not provide bulk or texture, allulose can replace sucrose with 90% fewer calories - while keeping typical sugar properties such as caramelizing, browning, texture, and bulk. Allulose is even capable of depressing the freezing point in frozen products like ice cream, a product where sugar was considered near impossible to be successfully replaced until very recently.

The secret behind allulose’s similar taste to sugar is its temporal profile, which is similar to sucrose with a clean and sweet taste. In summary, allulose provides attributes very much like sugar from cane, corn, or beet but with a significantly lower number of calories. From a health standpoint, allulose’s greatest asset lies in the fact that it is absorbed in the small intestine and excreted in the urine without being metabolized.16,17 As a consequence, allulose neither provides significant calories nor increases blood glucose and insulin levels. 18,19

Research indicates that consumers show a strong interest in reducing sugar and calories in their diets and have become more health conscious since the beginning of the pandemic, but taste has driven purchase decisions for decades when it comes to choosing foods and beverages.20 Rare sugars, as an ingredient solution that combines health and pleasure, can play a role in helping to solve for some of the key nutrition challenges we face today.
