Are Artificial Sweeteners Linked to a Rise in Blood Sugar?

Artificial sweeteners are also known as sugar alternatives, calorie-free sweeteners, and non-nutritive sweeteners. They provide sugar’s sweetness without the calories. In comparison to sugar, artificial sweeteners are much sweeter. As a result, artificial sweeteners need to be used sparingly to sweeten food. For this reason, foods sweetened artificially may contain fewer calories than foods sweetened with sugar.

Your blood sugar level is unaffected by sugar alternatives. The majority of artificial sweeteners are actually regarded as “free foods.” Free foods don’t count as calories or carbohydrates on a diabetes exchange since they have fewer than 20 calories and 5 grammes or less of carbohydrates. But keep in mind that even when foods contain artificial sweeteners, other components may still have an impact on your blood sugar level.

According to several studies, switching to artificial sweeteners from sugar-sweetened foods and beverages may not be as advantageous as previously believed. When artificial sweeteners are consumed in high quantities, this might be especially true. However, more study is required.

Be careful when using sugar alcohols, such as mannitol, sorbitol, and xylitol. Your blood sugar level can rise as a result of sugar alcohols. Additionally, sugar alcohols may also give some people diarrhea.

So, for instance, a can of diet coke won’t result in a spike in blood sugar.

However, Israeli researchers garnered media attention in 2014 when they connected artificial sweeteners to alterations in gut flora.

Artificial sweeteners generated unfavorable changes in the gut microbiota of mice that resulted in elevated blood sugar levels after being fed the sweeteners for 11 weeks.

They observed rises in blood sugar levels in the mice that received the germs from these mice.

It’s interesting that the scientists were able to restore normal gut bacteria and stop the rise in blood sugar levels.

These findings haven’t been examined or verified in people, though.

Only one human observational study has revealed a connection between aspartame and alterations in gut flora.

Therefore, it is unknown how artificial sweeteners would affect people over the long run.

Artificial sweeteners may theoretically increase blood sugar levels by harming gut microorganisms, although this hasn’t been scientifically shown.


Artificial sweeteners won’t temporarily increase blood sugar levels. The long-term impacts on people, however, are not known. So regular medical testing is needed to prevent upcoming difficulties

Increased Insulin Levels Caused by Artificial Sweeteners?

Artificial sweeteners and insulin levels have been the subject of conflicting research.

Various artificial sweetener varieties have different effects.


Sucralose consumption and elevated insulin levels have been linked in investigations on both humans and animals.

In one study, 17 participants underwent a glucose tolerance test after receiving either sucralose or water.

Sucralose recipients had blood insulin levels that were 20% higher. Additionally, they processed insulin from their systems more slowly.

Sucralose is thought to boost insulin levels by activating the mouth’s sweet taste receptors, a process known as cephalic phase insulin release.

Because of this, a research that administered sucralose intravenously rather than orally found no appreciable increase in insulin levels.


The most well-known and contentious artificial sweetener is likely aspartame.

Aspartame and elevated insulin levels have not been related in research, though.


Researchers have looked into whether stimulating the mouth’s sweet receptors with saccharin causes insulin levels to rise.

Mixed results are obtained.

According to one study, insulin levels increased after mouthwashing with a saccharin solution but before ingestion.

No effects have been reported in other investigations.

Acesulfame K is used for

Acesulfame potassium, often known as “acesulfame-K,” can raise rats’ insulin levels.

One experiment examined the effects of administering massive doses of acesulfame-K on insulin levels in rats. They discovered a significant rise of 114–210 percent.

Acesulfame-impact K’s on human insulin levels, however, remains unknown.


Depending on the type of stevia sweetener, artificial sweeteners appear to have varying effects on insulin levels.

Sucralose appears to raise insulin levels through activating oral receptors. The effects of other artificial sweeteners are currently unknown because there aren’t many high-quality human experiments.


In humans, sucrose and saccharin may increase insulin levels, but the evidence is conflicting and some studies show no impact. Although there are no studies on humans, acesulfame-K elevates insulin levels in rats.

If you have diabetes, may you use artificial sweeteners?

Diabetes is characterized by improper blood sugar regulation brought on by insulin resistance or insufficiency.

Contrary to excessive sugar consumption, artificial sweeteners won’t temporarily elevate your blood sugar levels. For diabetics, they are regarded as secure.

Long-term use’s potential health effects are not yet known.


Artificial sweeteners are safe sugar substitutes for diabetics because they don’t raise blood sugar levels.

Must You Steer Clear of Artificial Sweeteners?

Authorities in the US and Europe have deemed artificial sweeteners to be safe.

Artificial sweeteners are undoubtedly “less terrible” than refined sugar, even though they may not be “healthy.”

There isn’t any conclusive data to suggest that you should stop eating them if you include them in a balanced diet.

If you’re worried, you can substitute alternative natural sweeteners or just stop using sweeteners entirely.
