The U. Food and Drug Administration reviewed more than safety studies before approving it as a sweetener in But since then, research has raised questions about the safety of sucralose. Lots of people reach for diet soda and calorie-free sweeteners to keep their weight in check. But the jury is still out on whether artificial sweeteners actually help you keep off the pounds. Some studies have found no link between body weight and low-calorie sweeteners. Others have found that people who replace sugar with low-calorie sweeteners weigh ever-so-slightly less, on average — a difference, the researchers found, of fewer than two pounds.
On the other hand, some research suggests that people who drink diet soda might end up eating more calories in food than people who drink sugar-sweetened soda. Your gut is home to an entire community of helpful bacteria. The microbiome has several important jobs, including helping with digestion and aiding your immune system.
But some studies have found that sucralose might not be so great for those tiny helpers. Research in rodents shows that sucralose upsets the microbiome balance, and that can lead to increased inflammation.
Sucralose is a zero calorie artificial sweetener , and Splenda is the most common sucralose-based product.
Sucralose is made from sugar in a multistep chemical process in which three hydrogen-oxygen groups are replaced with chlorine atoms. It was discovered in when a scientist at a British college allegedly misheard instructions about testing a substance.
Instead, he tasted it, realizing that it was highly sweet. It was introduced in the United States in and is one of the most popular sweeteners in the country. Splenda is commonly used as a sugar substitute in both cooking and baking. Sucralose is calorie-free, but Splenda also contains the carbohydrates dextrose glucose and maltodextrin, which brings the calorie content up to 3.
However, the total calories and carbs Splenda contributes to your diet are negligible, as you only need tiny amounts each time. Sucralose is an artificial sweetener. Splenda is the most popular product made from it. Sucralose is made from sugar but contains no calories and is much sweeter. Sucralose is said to have little or no effects on blood sugar and insulin levels. However, these studies included people who regularly used sucralose 5 , 6 , 7. However, it probably has no effect on people who regularly use artificial sweeteners.
Splenda is considered to be heat resistant and good for cooking and baking. However, recent studies have challenged this. It seems that at high temperatures, Splenda starts to break down and interact with other ingredients 8. One study found that heating sucralose with glycerol, a compound found in fat molecules, produced harmful substances called chloropropanols. These substances may raise cancer risk 9. At high temperatures, sucralose may break down and generate harmful substances that could increase your risk of cancer.
The friendly bacteria in your gut are extremely important for your overall health. They may improve digestion, benefit immune function and reduce your risk of many diseases 12 , Interestingly, one rat study found that sucralose may have negative effects on these bacteria. Beneficial bacteria like bifidobacteria and lactic acid bacteria were significantly reduced, while more harmful bacteria seemed to be less affected. Animal studies link sucralose to negative effects on the bacterial environment in the gut.
However, human studies are needed. Artificial sweeteners are low-calorie or calorie-free chemical substances used instead of sugar to sweeten foods and drinks. They're found in thousands of products, from drinks, desserts and ready meals, to cakes, chewing gum and toothpaste. As part of the evaluation process, the EFSA sets an acceptable daily intake ADI , which is the maximum amount considered safe to consume each day over the course of your lifetime.
You do not need to keep track of how much sweetener you consume each day, as our eating habits are factored in when specifying where sweeteners can be used. Sweeteners may be safe, but are they healthy? Food manufacturers claim sweeteners help prevent tooth decay, control blood sugar levels and reduce our calorie intake.
EFSA has approved the health claims made about xylitol, sorbitol and sucralose , among others, in relation to oral health and controlling blood sugar levels.
