Moreover, saccharin passes through the body without being metabolized and thus has no caloric content. Aspartame NutraSweet TM , currently the most-used artificial sweetener, also binds to T1r3 more strongly than sucrose does and tastes nearly times as sweet. Unlike saccharin, however, aspartame is metabolized, yielding methanol and the amino acids phenylalanine and aspartic acid. Further metabolism of these products does yield calories, but far fewer than those obtained from the amount of sucrose required to produce the same sweetening effect.
Arno F. Spatola is a professor of chemistry and the director of the Institute for Molecular Diversity and Drug Design at the University of Louisville, where his current research focuses on peptides, including artificial sweeteners. He provides the following answer: Is there any caloric value to artificial sweeteners? How am I able to have my cake the sweetness of my food and eat it too avoid gaining weight from excess calories?
The answer to these questions, as in most areas of science, is that it depends. Sweetness is a taste sensation that only requires interaction with receptors on our tongues. Many sugar substitutes, such as saccharin and acesulfame K also known as Sunette TM , do not provide any calories. This means that they are not metabolized as part of the normal biochemical pathways that yield energy in the form of adenosine triphosphate, or ATP.
In some cases, small quantities of additives such as lactose are added in order to improve the flow characteristics or to add bulk to the products. But the quantities of these added ingredients are so small that they do not represent a significant amount of energy-producing foodstuffs. Sign up for our email newsletter. Already a subscriber?

That number is projected to jump to 1, million people by , making Knowing you may live well into your 80s or 90s can provide the motivation for living better now to extend the quality of your life as you get older. Since the introduction of aspartame into the food supply in the s as an artificial sweetener times sweeter than sugar, a growing body of research has demonstrated its role in a healthy lifestyle, including help with:.
Knowing low-calorie sweeteners can support weight management is significant because, along with getting older, the World Health Organization reports we are also getting heavier.
In fact, obesity has more than doubled in the global population since Today overweight and obesity are the leading risk factors for noncommunicable diseases such as heart disease, stroke, diabetes and some cancers and are now linked to more deaths worldwide than being underweight. If you want to prevent the chronic diseases that can strip away independence as you age, achieving a healthy body weight is one of the most important steps you can take.
For a pound person that would be the amount of aspartame in 17 cans of diet soda or 97 packets of the sweetener. While that is much more than anyone could possibly consume every day over a lifetime, it is reassuring to know they would not be adversely affected even at that high a level. Food safety experts report aspartame does not cause damage to the genes or induce cancer, does not harm the brain or nervous system, and does not affect behavior or cognitive function in children or adults.
They also have found no risk to the developing fetus from its use during pregnancy at the current ADI levels except in women suffering from PKU.
Regulatory agencies representing more than 90 countries have conducted their own scientific reviews of the research on aspartame and approved it as safe for their populations. It is reassuring to know there is a consensus among so many experts about the safety of aspartame, especially when conflicting reports are in the news.
