People may use LCS in place of sugar to consume fewer calories or less sugar or to better control their blood glucose if they have diabetes or prediabetes. There are six LCS approved as food additives by the U. They are all sweeter than table sugar sucrose but contain few or no calories. They include:. Calculations are based on a pound individual. Sugar alcohols, or polyols, are not classified as LCS but have slightly less calories than table sugar.
They do not promote tooth decay or cause sharp rises in blood glucose. Examples are sorbitol, xylitol, lactitol, mannitol, erythritol, and maltitol. They are found in sugar-free candies, cookies, ice cream, beverages, and chewing gums. They are also used in toothpastes and medicines like cough syrups. In some people, eating high quantities of certain sugar alcohols can cause loose stools or diarrhea. They are absorbed slowly and may cause extra water to be drawn into the intestines.
Erythritol is an exception because it is well-tolerated in most people even when eaten in larger amounts. The health effects of LCS are inconclusive, with research showing mixed findings.
Research is also looking at potential differences in effects from the various types of LCS. The following reviews research specific to LCS beverages. Long-term observational studies show that regular consumption of LCS beverages reduces calorie intake and promotes less weight gain or weight maintenance, but other research shows no effect, and some studies even show weight gain. Different comparisons among studies may also produce different results; for example, was LCS beverage intake being compared with SSBs, juice, or water?
The human brain responds to sweetness with signals to eat more. By providing a sweet taste without any calories, however, LCS beverages may cause us to crave more sweet foods and drinks, which can add up to excess calories.
Researchers say the sugar substitutes added to foods and drinks can lead to long-term weight gain as well as diabetes, high blood pressure, and heart….

The Truth About Artificial Sweeteners. The molecular structure of T1r3 can be seen here. Like all receptor proteins, T1r3 has a well-defined "pocket" where smaller molecules may enter and perhaps bind.
Binding depends on a good fit of molecular shape and the presence of groups that interact chemically to stabilize binding. Sucrose, the sugar in the sugar bowl, binds fairly well to T1r3 and hence leads to a sweet sensation in the brain. Enzymes readily metabolize sucrose, releasing energy and, if our diet contains excess calories, causing fat deposition.
Saccharin, once the most popular artificial sweetener, binds to T1r3 much more strongly than does sucrose, owing to the differing structures of the two molecules. Therefore, we sense saccharin as being approximately times as sweet as the same amount of sucrose.
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.
