Role in a healthy diet

Low/no calorie sweeteners provide a simple way to reduce the amount of sugars and the intake of calories in our diet. When used as part of a healthy diet and lifestyle, low/no calorie sweeteners can help us meet current public health recommendations to reduce excessive sugar consumption without affecting the enjoyment of sweet-tasting foods and drinks.

Sweet taste in our diet

Sweetness liking is innate and spans across all ages and cultures around the world, which makes sweet taste an integral part of the human diet. At the same time, reducing excessive sugar intake is a public health recommendation. However, getting people to significantly cut out sweetness in their diet is a challenge. The key benefit of low/no calorie sweeteners is that people can still enjoy food and drinks that have a sweet taste and contain less sugar and fewer calories. In many instances, consuming a low/no calorie sweetened drink can help lower the desire for sweetness and the intake of sweet foods.1

The role of low/no calorie sweeteners in sugar reduction

At a time of worrying rates of obesity and non-communicable diseases (NCDs) globally, governments around the world are committed to addressing this shared challenge with a whole-of-society approach, involving all relevant actors. Policy makers have urged food and drink companies to contribute to reducing NCDs risk factors and to creating healthy food environments by reformulating products to provide healthier options.2,3

Due to their properties, low/no calorie sweeteners enable manufacturers to support these health objectives by developing foods and drinks with less energy and less sugars. By having a very high sweetening power compared to sugars, in practice, low/no calorie sweeteners are used in minute amounts to confer the desired level of sweetness to foods and drinks, while contributing very little or no energy at all to the final product.4

When used as part of a healthy diet and lifestyle, low/no calorie sweeteners can help us meet current public health recommendations to reduce excessive sugar consumption without affecting the enjoyment of sweet-tasting foods and drinks. Indeed, consumers of low/no calorie sweetened beverages have higher chances of meeting the recommendation for free sugars’ intake, compared to consumers of sugar-sweetened beverages, according to a recent UK study.5

Low/no calorie sweeteners are useful in reducing calorie intake

By replacing sugars in foods and beverages, low/no calorie sweeteners help decrease the energy density of these foods (the amount of calories per gram of food), which, in turn, can mean significant calorie savings. Numerous studies testing the impact of the consumption of low/no calorie sweeteners on calorie intake of the following meal and on total daily energy intake show that there is a significant caloric decrease with low/no calorie sweeteners’ use when compared to sugar, with no significant difference when compared to water or other unsweetened drinks.6,7

Low/no calorie sweeteners as part of a healthy diet

Nutritional guidelines around the world encourage individuals to follow a healthy dietary and lifestyle pattern to support overall health and wellbeing including a healthy body weight. Eating sensibly, choosing a high-quality varied diet from a range of foods and keeping active are all great ways to promote health.

Choosing low/no calorie sweetened foods or drinks has been linked with improved diet quality in different populations around the world such as in the USA, the UK and Brazil.5,8-10 Research shows that consumers of low/no calorie sweetened products tend to have higher-quality diets with less sugar-containing food products and higher intakes of other healthy food groups such as fruits and vegetables.

Low/no calorie sweeteners are also frequently used in weight management efforts and/ or as part of a successful weight loss maintenance strategy.11 People being in a weight-loss effort or who wish to manage their body weight or their glucose levels are using low/no calorie sweetened foods and drinks more often.12,13 Recent research also suggests that the consumption of diet drinks sweetened with low/no calorie sweeteners may help dieters to control food intake when in a state of craving, and also to align potentially conflicting goals of dieters, i.e. pleasurable eating and weight control.14
