Think honey is healthier than sugar? What to know
Portion size – and the rest of your diet – matters far more than the color or thickness of the sweetener you choose.
Non-nutritive sweeteners may aid sugar reduction without affecting weight or health
The review, led by Eva Marija Čad of the University of Ljubljana and Wageningen University & Research, alongside Professor Graham Finlayson of the University of Leeds and colleagues from other institutions in the Netherlands, Denmark, Spain and Belgium, was developed in connection with a 2025 webinar series hosted by the Institute for the Advancement of Food and Nutrition Sciences (IAFNS).
No Evidence That Sugar Substitutes Harm Weight, Health, or Sweet Taste Preferences
New review of three major EU-funded trials shows swapping sugar for non-nutritive sweeteners may help with weight loss maintenance, while broader "sweet taste" exposure appears largely neutral for health.
Popular sweeteners may leave effects that last for generations
Two widely used zero-calorie sweeteners, sucralose and stevia, may have effects that linger far longer than the sweet taste itself. In mice, researchers found that both sweeteners altered the gut microbiome, reduced beneficial compounds produced by gut bacteria, and changed the activity of genes involved in metabolism and inflammation. Some of those changes were also detected in later generations that had never consumed the sweeteners themselves.
Artificial sweeteners might make you lose your memory
A new study found a 62% faster loss of cognitive decline among those using sweeteners
How to navigate the confusing world of artificial sweeteners
The wide array of sweeteners available on the market can be confusing, and not all are equally healthy.
Low-cal sweeteners can change gut bacteria — especially if you're on a popular antidepressant
That guilt-free treat may not be as innocent as it seems.
Scientists tested 39 sweeteners and found unexpected gut effects
A large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently when combined with medications, caffeine, or flavorings. The combination of isosteviol and the antidepressant duloxetine was especially disruptive, reducing beneficial bacteria and overall microbial diversity.
Sugar substitutes are low in calories, but may disrupt your metabolism, study says
Artificial sweeteners also may increase risk of type 2 diabetes and heart disease, the research shows.
Iranian Guards' business empire to win big if U.S. sanctions lifted
Emerging outlines of a deal between Washington and Tehran to end their war contain a stinging paradox: sweeteners to coax Iran into compliance may strengthen an adversarial force that the U.S. and its Western allies consider a terrorist organisation.
IFF Shares Climb on $4.3 Billion Deal to Sell Food-Ingredients Business

Scientists say this common sweetener may be quietly rewiring your metabolism
Researchers say fructose is not just “empty calories” — it may actively push the body toward fat storage and metabolic disease. A new review found that fructose affects the body differently from glucose, disrupting normal energy regulation and promoting processes linked to obesity, insulin resistance, and cardiovascular problems.

Artificial sweeteners: Why the science war is raging on
Conflicting studies on artificial sweeteners are fuelling fresh debate across food and drink, as health risks, regulation and reformulation collide worldwide.
Ingredion and Holobiome map gut microbiome to unlock targeted health benefits
Ingredion has partnered with Holobiome to use AI and its database of two million bacterial genomes to predict how specific ingredients will interact with human health before clinical trials. The research expands beyond digestion to explore how sweeteners, plant proteins, and texture solutions influence the gut-brain axis, including sleep and mental health.

Zero sugar but at what cost?
Sugar-free sweeteners may still be harming your liver
Sorbitol, a popular sugar-free sweetener, may not be as harmless as its label suggests. Researchers found it can be turned into fructose in the liver, triggering effects similar to regular sugar. Gut bacteria can neutralize some of it—but too much sorbitol or glucose can overwhelm that defense. The result: yet another “healthy” sweetener that may stress the liver.
What’s worse for us, sugar or sweeteners?
We all know eating too much sugar is bad for our health – but would we be better off replacing it with artificial sweetener? It’s a question Science Weekly listener Marion posed recently and, as Madeleine Finlay tells Ian Sample, the answer is complicated. She explains what the science says about sugar v sweeteners with the help of Prof Havovi Chichger, from Anglia Ruskin University, and Prof Jim Krieger, from the University of Washington’s school of public health
