The Latest Scientific Evidence Should Be the Death Blow to Artificial Sweeteners

Messing with the microbes in your digestive process is not the way to go.


Evidence continues to accumulate that sugar is a sweet road to obesity, diabetes, Alzheimer’s, and other maladies. As the dangers of sugar have unfolded there has been an increase in the production and consumption of sugar substitutes, five of which are currently FDA-approved. A recent study published in Nature adds to a growing set of concerns about these artificial sweeteners by presenting evidence that they, like sugar, can cause diabetes as well. The Israel-based research team presented evidence that artificial sweeteners cause this outcome by disrupting the balance of microbes that live in the body’s gut.

This isn’t the first study implicating sugar substitutes with metabolic issues. Research at Purdue University found that saccharin consumption can lead to weight gain in mice by interfering with their ability to control their appetites. Multiple studies have shown that some artificial sweeteners can mess with the body’s endocrine system, and lead to insulin resistance. Many links between the consumption of artificial sweeteners and type 2 diabetes have been uncovered as well, and studies have also shown that consumption of artificial sweeteners can change the way the body deals with food that contains actual calories.

The link between artificial sweeteners, gut bacteria and obesity has been charted as well, in a Duke University study that found that Splenda (sucralose) reduces the amount of ”good bacteria” in the intestines, increases the intestinal pH level, and leads to increased body weight.

The new Nature study moves this ball of research forward by demonstrating that several artificial sweeteners, not just sucralose, can mess with our gut bacteria, and that this disruption is directly responsible for glucose intolerance—at least in mice. The researchers added three different artificial sweeteners (AS)—saccharin, sucralose and aspartame—to the drinking water of mice. After 10 weeks, all three groups of artificial sweetener-consuming mice showed glucose intolerance. Saccharin showed the most pronounced effect.

As the Duke study had shown that sucralose causes changes in the gut microbiota in mice, the Israeli researchers used antibiotics to wipe out the microbes in the mice …read more
