artificial sweetners

Most of my dieting or weight-conscious friends rely on the bevy of artificial sweeteners on the market to aid their quest of finding “their svelte outer selves.” For example, we have saccharin, the oldest of the bunch, sucralose, aspartame, and stevia, available in rainbow-pastel-colored packets for the asking. Is one better than the other?
Every action we take, every discovery or innovation we make, has consequences, many of them unintentional. Consider artificial sweeteners (AS), developed to fulfill many needs: to reduce calories in processed foods such as soft drinks, lower glycemic indices for patients with diabetes, and aid dieters in weight loss. Now, scientific literature reports that AS, like microplastics, are emerging as trace pollutants in our waters and soils.
There’s an epidemic of obesity and diabetes, and everyone is trying to lose weight. Many individuals use artificial sweeteners to reduce their caloric intake. A recent article titled “Aspartame and cancer: new evidence for causation” is just the latest of several studies over the years that have attempted to link artificial sweeteners – in this case, aspartame – with cancer. Is there any evidence for an association?
