Is There A Connection Between Artificial Sweeteners And Diabetes

Artificial Sweeteners Do Not Effect Insulin & Blood Sugar

Because artificial sweeteners arent digested, they pass through the gastrointestinal tract and come into direct contact with the bacteria that normally reside there. Investigators studied the effect that three artificial sweeteners have on these intestinal bacteria. Since changes in the intestinal microenvironment have been linked to diabetes and metabolic syndrome, the researchers wanted to learn whether or not the artificial sweeteners caused changes that could lead to impairment in glucose metabolism. They conducted experiments in which mice drank either normal water or water supplemented with three different kinds of artificial sweeteners . The mice in all three of the groups consuming artificial sweeteners developed glucose intolerance, with higher blood glucose levels than the mice drinking water alone. Further, the effect was also observed in mice that were fed a high-fat diet, indicating that the sweeteners had the effect in both the lean state and the high-fat state . They went on to conduct experiments that proved that the elevated glucose levels in the sweetener-consuming mice were directly related to changes in the intestinal bacterial composition.

Sucralose The Most Popular Sugar Substitute

This sweetener is excellent for people with type 2 diabetes. Thats because Splenda is 600 times sweeter than sugar, yet those little yellow packets have no effect on blood sugar, says Keri Glassman, RD, CDN, of Nutritious Life, a nutrition practice based in New York City.In addition, Splenda passes through the body with minimal absorption. These attributes have helped it become the most commonly used artificial sweetener worldwide, according to an article published in October 2016 in Physiology & Behavior.

The Food and Drug Administration , which has approved sucralose, recommends an acceptable daily intake of 5 milligrams or less of sucralose per kilogram of body weight per day. A 132-pound individual would need to consume 23 tabletop packets of the artificial sweetener per day to reach that limit.

People Should Consume Sweetness In Moderation

While insulin responses to either tasting or swallowing the sucralose were similar in those of normal weight, those responses were very different in people with obesity, says Prof. Pepino. Therefore, we hypothesize that some post-ingestive effects of sucralose may occur only in people with obesity.

The researcher cautions, however, that different sweeteners have different chemical structures, so the findings of this study, regarding the post-ingestive effects, may apply exclusively to sucralose. Nevertheless, the effect of sweet taste alone may be more generalizable.

Intriguingly, and contrary to what the researchers expected, the study also found that merely tasting the sweetener had a metabolic effect, as well.

Interestingly, we found that in both groups of people those with obesity and those of normal weight there was a reduction in insulin response to the glucose tolerance test when they just tasted sweetness before drinking the glucose solution.

It was the most surprising finding, and we are following up on that in a new study, explains Prof. Pepino.

The researchers acknowledge the limits of their results, saying, What our data suggest is that there are mechanisms that we dont understand clearly about how the human body regulates glucose, and the potential metabolic effects of tasting something sweet beyond providing a sense of pleasure.

However, they stress the importance of eating sweet foods in moderation.

Types Of Artificial Sweeteners

There are various artificial sweeteners licensed for use in the UK. These include:

  • aspartame, used in Canderel, Hermesetas granulated
  • saccharin, used in Hermesetas mini sweeteners
  • sucralose, used in Splenda
  • acesulfame potassium , used in Hermesetas Gold sweetener
  • cyclamate, used in Hermesetas liquid.

Some products are made from a combination of two artificial sweeteners. For example, Hermesetas Gold sweetener is made from a blend of aspartame and acesulfame-K.

Are Sugar Alcohols Considered Artificial Sweeteners

Does artificial sweetener raise your blood sugar ...

Sugar alcohols are a type of sugar substitute, but theyre grouped separately from artificial sweeteners. Sugar alcohols, like artificial sweeteners, are metabolized differently than table sugar in your body. The difference between artificial sweeteners and sugar alcohols is that sugar alcohols are carbohydrates, meaning they have some calories and can have an effect on blood glucose levels however, they only require a very small amount of insulin, after consumption, to bring glucose back down.

Most sugar alcohols can be identified on a food label with the ending -tol: sorbitol, xylitol, lactitol, mannitol, glycerol, erythritol, and maltitol. However, isomal, glycerin, glycerine and starch hydrolysates are also sugar alcohols. On a food label, sugar alcohols are in their own group so its easy to identify if your packaged food contains them.

Sugar alcohols are usually either equal in sweetness level to table sugar or as low as 25% as sweet. They are not associated with tooth decay or a significant spike in blood glucose levels, according to the FDA.

Dangerous Effects Of Artificial Sweeteners On Your Health

Can sugar, an American staple used by countless bakers and cooks, really be that terrible for you?

Well, yes. For some time now, eating sugar-sweetened foods and beverages has been identified as the cause of any number of negative health prospects, including being overweight or even obese, type 2 diabetes, and metabolic syndrome. Because of these findings, many health care experts have proposed that non-caloric, high-intensity sweeteners provide, if not a beneficial alternative to sugar, at least a less damaging one. Many people switched from regular soft drinks to ‘diet’ versions of the same and started checking the labels on other foods and beverages to make sure they were made with something other than sugar.

Yet many other claims — confusing claims — have been cited over the years. Studies spanning the past 40 years have suggested alternately that sugar-substitutes may be ‘potentially helpful,’ ‘potentially harmful,’ or have ‘unclear effects’ with regard to your health. New evidence, in fact, states that people who frequently consume sugar substitutes may be at an increased risk of excessive weight gain, metabolic syndrome, type 2 diabetes, and cardiovascular disease.

Truth is, when it comes to artificially-sweetened beverages, as few as one of these drinks per day may be enough to significantly increase the risk for a number of health problems.

How Do Artificial Sweeteners Affect My Glucose Levels

Will artificial sweeteners spike your glucose levels or are they a metabolic health freebie? We break down the research and give you some sweetener advice.

Eating something sweetened with a sugar substitute wont by itself cause your glucose levels to spike. Thats because these artificial sweeteners dont actually contain glucose they just stimulate your sweet receptors so you get the taste without the calories.

And while that sounds like a get-out-of-glucose-jail-free card, studiessuggest these sweeteners can have metabolic consequences, influencing your bodys ability to process glucose and insulin over time, and even contributing to obesity.

The science on these substances is extensive, but complex and often contradictory. So lets break down what we know and what you can do about it.

A Note To Household Chefs

Are Artificial Sweeteners More Harmful Than Sugar?

Aspartame loses sweetness when cooked. Sucralose, acesulfame-K and saccharin can be used for baking. Look for special baking recipes for artificial sweeteners, as direct substitution for sugar might not give you the result you want. Or, try a combination of artificial sweetener and sugar in recipes to get your desired result while lowering the overall carbohydrate amount. Keep in mind that some artificial sweeteners can be sweeter than equal amounts of natural sugar. A little bit goes a long way.

Sugar Substitutes That Are Not Blood Sugar Friendly


Lets start with honey because, lets face it, its sugar in liquid form .

Its delicious, but a 2015 study in the Journal of Nutrition found that when subjects were given honey, cane sugar, or high-fructose corn syrup, they saw no notable difference in blood sugar increase.

The only benefit of honey over regular table sugar from a blood sugar perspective is that honey is slightly sweeter so you can use a little bit less of it and achieve the same sweetness. But that still doesnt make it a good option for people with diabetes!

Agave Nectar

I think that the corporate marketing machine has been very clever when declaring agave nectar is a health food, for as Dr. Jonny Bowden points out..Its basically high-fructose corn syrup masquerading as healthy food.

Agave nectar may have a lower glycemic index than sugar or honey, but its still up to 90 percent liquid fructose.

At the end of the day, sugar is sugar. Honey or agave nectar may be slightly better for you than pure white sugar from an overall nutrition perspective, but dont get tricked into thinking that they are blood sugar-friendly alternatives.

Final Thoughts On Artificial Sweeteners

Many countries have declared artificial sweeteners safe to use in food and drink. However, the science is clear: Artificial sweeteners can affect your blood sugar and insulin levels. The long-term impact of consuming these synthetic ingredients shouldnt be disregarded. If you are trying to get healthier or bring your type 2 diabetes under control, you should avoid using artificial sweeteners on a daily basis.

Which Artificial Sweeteners Raise Blood Sugar

Most artificial sweeteners provide little to no calories or carbohydrates because of the way they are digested and broken down in the body. We know that carbs raise blood sugar, so how do some artificial sweeteners affect blood sugar? The answer lies in your gut. Your gut microbiome houses billions of microorganisms such as bacteria and it can directly affect your healthfrom your weight to your digestion to your blood sugar levels.

A 2014 study found that certain artificial sweeteners can raise blood sugar levels by potentially changing the composition of the bacteria in your gut in a way that worsens glucose tolerance and increases the risk of metabolic syndrome, which is closely tied to symptoms of insulin resistance. The researchers found a correlation between the consumption of artificial sweeteners and an increase in certain parameters related to metabolic syndrome, such as:

  • Weight

The study found that the following sweeteners raised blood sugar:

  • Saccharin
  • Aspartame

What Amount Of Sweetener Is Safe To Eat

Do Artificial Sweeteners Affect Blood Sugar and Insulin ...

As part of the approval process for each non-nutritive sweetener, an Acceptable Daily Intake level is set. The ADI is the estimated amount per kilogram of body weight that a person can consume, on average, every day, over a lifetime without risk. ADIs are set 100 times less than the smallest amount that may cause health concerns, so its extremely difficult for most people to reach the ADI. With these checks, the current levels of intake of artificial sweeteners in the UK are safe, although people with phenylketonuria are advised to avoid sweeteners containing aspartame.

Splenda And The Gastrointestinal System

Research suggests that sucralose doesn’t typically have a substantial effect on gut microbiota, which is the normal bacterial composition of the digestive system that is necessary to digest food and protect you from infections.

However, sucralose and other artificial sweeteners can have an effect on your gut microbiota and worsen your symptoms if you have inflammatory bowel syndrome.

What About Natural Sweeteners

Heres some potential good news: Studies suggest stevia may not suffer these same drawbacks. In one, test subjects showed lower levels of glucose and insulin after a meal when they ate stevia first compared to people who ate sucrose or aspartame. Other research has even shown it can lower blood sugar in diabetics. Similarly, sugar alcohols seem not to show negative metabolic effectsthey can, however, cause digestive issues at high doses.

Artificial Sweeteners: Sweet Taste In Itself May Affect Metabolism

Sweetness should be consumed in moderation, regardless of the calories, caution researchers, as a new study reveals the impact of consuming artificial sweeteners on metabolism and glucose control.

Lately, we have been hearing a lot in the media about the dangers of sugar consumption. Added sugar raises the risk of obesity, cardiovascular disease, and type 2 diabetes, not to mention having an addictive effect on the brain.

Therefore, in an attempt to avoid sugar, many people have turned to low calorie sweeteners instead. Artificial sweeteners provide the sweet taste with none of the side effects, so it appears to be a welcome and healthful trick.

So, many people have bought into the idea that, according to some estimates, about a quarter of children in the United States, and more than 40% of adults, are currently consuming low calorie sweeteners.

But, are artificial sweeteners as harmless as people seem to think? Research from a few years ago suggested that artificial sweeteners can still promote diabetes and obesity. And now, a new study adds to the evidence that sweeteners may have undeniable metabolic effects.

In fact, the latest study suggests that merely tasting something sweet could alter our metabolism and glucose control.

M. Yanina Pepino, a professor of food science and human nutrition at the University of Illinois in Chicago, is the lead author of the new paper, which appears in the journal Nutrients.

How Artificial Sweeteners Affect Blood Sugar And Insulin

Study Raises Questions About Artificial Sweeteners

Sugar is a hot topic in nutrition.

Cutting back can improve your health and help you lose weight.

Replacing sugar with artificial sweeteners is one way to do that.

However, some people claim that artificial sweeteners arent as metabolically inert as previously thought.

For example, its been claimed that they can raise blood sugar and insulin levels.

This article takes a look at the science behind these claims.

Should People With Diabetes Use Splenda

Evidence from many studies suggests that consuming artificial sweetenerssucralose includeddoes not affect blood sugar levels. These studies show that sucralose should be safer than sugar for people with diabetes.

However, there is evidence that drinking diet sodas increases the risk of type 2 diabetes and obesity, along with high blood pressure, high blood sugar, and other symptoms of metabolic syndrome that could ultimately lead to diabetes.

In one study, individuals in a group each added 15 milligrams of Splendaabout one packetper day to the food or beverage of their choice. After 14 days, those who ate Splenda had higher insulin resistance than people in another group who were not given Splenda at all.

If you have insulin resistance, it is more difficult for your body to take glucose from your bloodstream and convert it into energy. This leads to high blood sugar that, if untreated, could eventually lead to type 2 diabetes.

Researchers stress that more studies are needed to identify the health effects that consuming sucralose over the long term could have.

Beware That Some Artificial Sweeteners Have Calories

Artificial sweeteners can be non-nutritive or nutritive, although most artificial sweeteners fall under the non-nutritive umbrella. “Non-nutritive sweeteners are synthetic sugar substitutes that are free of calories and carbohydrates. They may be derived from naturally occurring plants or herbs and are many times sweeter than sugar,” says Daghigh.

The other category of artificial sweetener is nutritive, which only includes aspartame. “The nutritive sweeteners may be lower in calories when compared to sugar and add caloric value to the foods that contain them,” says Daghigh.

Ask The Doctor: Do Artificial Sweeteners Cause Insulin Resistance

Ask the doctor Q. I’ve heard that artificial sweeteners increase the risk of developing insulin resistance. Is that true? Are some types worse than others? A. You’ve asked a question scientists are still working to answer. Studies of artificial sweeteners are mixed, with some indicating that people using them eat fewer calories and lose weight or maintain a stable weight. However, in a few studies, artificial sweeteners were associated with weight gain, which might increase the risk of developing insulin resistancea condition in which body cells do not respond properly to insulin and thus cannot easily absorb glucose from the blood-stream.

Erythritol A Sugar Alcohol With Fewer Side Effects Than Other Options

Artificial sweeteners could cause spikes in blood sugar ...

Erythritol is also a sugar alcohol sweetener, but unlike the others just mentioned, it has less than 1 calorie per gram, notes the International Food Information Council Foundation, and doesnt have a big effect on blood sugar levels, per the American Diabetes Association. Its an ingredient in the stevia-derived sweetener Truvia and is marketed under the brand-name Swerve. Swerve measures cup-for-cup like sugar, and you can use it like table sugar, or in cooking and baking recipes that call for sugar.

If other sugar alcohol sweeteners give you tummy trouble, this may be a better option for you. It is less likely to produce the gas, bloating, and diarrhea that happen from fermentation by gut bacteria because only about 10 percent of the erythritol you consume enters the colon, per past research. The rest leaves the body through your urine.

Theres no ADI for erythritol, but the FDA hasn’t questioned notices submitted by erythritol makers that the sweetener is generally recognized as safe.
