To make sucralose, sugar undergoes a multistep chemical process in which three pairs of hydrogen-oxygen atoms are replaced with chlorine atoms. The resulting compound is not metabolized by the body So while sucralose itself is calorie-free, the fillers found in most sucralose-based sweeteners like Splenda provide about 3 calories and 1 gram of carbs for every 1-gram serving Maltodextrin and dextrose are typically made from corn or other starch-rich crops. Combined with sucralose, they contain 3.
The acceptable daily intake ADI of sucralose is 2. For a pound kg person, this equals about 23 single-serve 1-gram packets 9. Given that 1 gram of Splenda contains mostly filler and only 1. Aspartame comprises two amino acids — aspartic acid and phenylalanine. While these are both naturally occurring substances, aspartame is not Although aspartame has been around since , the Food and Drug Administration FDA did not approve it for use until Being times sweeter than sugar, only a small amount of aspartame is used in commercial sweeteners.
Like sucralose, aspartame-based sweeteners usually contain fillers that mellow the intense sweetness 9. For example, one single-serve 1-gram packet of Equal has only 3. For a pound kg person, that equals the amount found in 75 single-serve 1-gram packets of NutraSweet 9. For further context, one ounce ml can of diet soda contains about mg of aspartame. This means that a pound kg person would have to drink 21 cans of diet soda to surpass the ADI Only a tiny amount is the intensely sweet sucralose Thus, while aspartame- and sucralose-based sweeteners share some of the same fillers, Splenda does not contain aspartame.
Sucralose and aspartame are artificial sweeteners. Fillers help mellow their intense sweetness and add a few calories. Splenda does not contain aspartame, though it has fillers that are also found in aspartame-based sweeteners. A lot of controversy surrounds the safety and long-term health effects of artificial sweeteners like sucralose and aspartame. Sucralose has also been thoroughly researched, with over studies pointing to its safety Specifically, there have been concerns about aspartame and brain cancer — yet extensive studies have found no link between brain cancer and consuming artificial sweeteners within safe limits 17 , 19 , 20 , Other side effects associated with the use of these sweeteners include headaches and diarrhea.
If you experience these symptoms consistently after consuming foods or beverages containing these sweeteners, they may not be a good choice for you. Furthermore, recent concerns have been raised regarding the negative effects of the long-term use of artificial sweeteners on healthy gut bacteria , which are needed for optimal health.
However, the current research was conducted in rats, so human studies are needed before conclusions can be made 14 , 22 , 23 , Calories are a measure of the energy made available when we digest and metabolize food. The energy drives the replacement of molecules we have lost, enables us to move, and so forth; we store excess energy as fat. A substance that we do not metabolize releases no energy it "has no calories" and is not a food. A sweet taste results from the binding of molecules to specific receptor proteins in our taste buds.
Sweet-taste-sensory cells in the taste buds have these receptor protein molecules embedded in their plasma membranes. Binding of a molecule to a receptor protein initiates a cascade of events within the taste-sensory cell that eventually releases a signaling molecule to an adjoining sensory neuron, causing the neuron to send impulses to the brain.
Within the brain, these signals derived from the taste bud cause the actual sensation of sweetness. Other sensory cells, with different receptor proteins, report on other taste modalities: salty, sour, bitter, and "umami" also referred to as glutamate, or "meat".
The events that occur between binding by the "sweet receptor" and the sensation in the brain have nothing to do with whether a molecule can be metabolized to yield energy and thus "has calories. So, what determines this binding ability? In April , two research teams published independent contributions to answering this question. Both papers announced and described a protein, dubbed T1r3, which appears to be the primary receptor for sweet substances.
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.
