Artificial Sweeteners: Good or Bad?: Artificial sweeteners are sometimes the subject of heated debate.

On one hand, they’re claimed to increase your risk of most cancers and hurt your blood sugar and gut health.

On the opposite hand, most health authorities think about them protected, and many people use them to reduce their sugar intake and lose weight.

This article reviews the proof on artificial sweeteners and their health results.

What are artificial sweeteners?

Artificial sweeteners, or sugar substitutes, are chemicals added to some foods and beverages to make them taste sweet.

People typically seek advice from them as “intense sweeteners” as a result of they supply a taste much like that of desk sugar but as much as a number of thousand times sweeter.

Although some sweeteners contain calories, the amount wanted to sweeten products is so small that you find yourself consuming nearly no calories (1Trusted Source).


Artificial sweeteners are chemicals used to sweeten foods and beverages. They present nearly zero calories.

How do artificial sweeteners work?

The floor of your tongue is roofed by many taste buds, every containing a number of taste receptors that detect totally different flavors (2Trusted Source).

When you eat, your taste receptors encounter food molecules.

A good match between a receptor and molecule sends a sign to your brain, permitting you to establish the taste (2Trusted Source).

For instance, the sugar molecule matches completely into your taste receptor for sweetness, permitting your brain to establish the sweet taste.

Artificial sweetener molecules are comparable enough to sugar molecules to suit on the sweetness receptor.

However, they’re typically too totally different from sugar in your body to interrupt them down into calories. This is how they supply a sweet taste with out the added calories.

Only a minority of artificial sweeteners have a structure that your body can break down into calories. Given that only very small amounts of artificial sweeteners are wanted to make foods taste sweet, you consume nearly no calories (1Trusted Source).


Artificial sweeteners taste sweet as a result of they’re recognized by the sweetness receptors in your tongue. They present nearly zero calories, as your body can’t break them down.

Common artificial sweeteners

The following artificial sweeteners are allowed to be used in the United States and/or European Union (3Trusted Source4):

  • Aspartame. Sold under the model names NutraSweet, Equal, or Sugar Twin, aspartame is 200 times sweeter than desk sugar.
  • Acesulfame potassium. Also often called acesulfame K, it’s 200 times sweeter than desk sugar. It’s fitted to cooking and baking and offered under the model names Sunnet or Sweet One.
  • Advantame. This sweetener is 20,000 times sweeter than desk sugar and fitted to cooking and baking.
  • Aspartame-acesulfame salt. Sold under the model identify Twinsweet, it’s 350 times sweeter than desk sugar.
  • Cyclamate. Cyclamate, which is 50 times sweeter than desk sugar, was used for cooking and baking. However, it has been banned in the United States since 1970.
  • Neotame. Sold under the model identify Newtame, this sweetener is 13,000 times sweeter than desk sugar and fitted to cooking and baking.
  • Neohesperidin. It’s 340 times sweeter than desk sugar and fitted to cooking, baking, and mixing with acidic foods. Note that it’s not authorized to be used in the United States.
  • Sacchari. Sold under the model names Sweet’N Low, Sweet Twin, or Necta Sweet, saccharin is 700 times sweeter than desk sugar.
  • Sucralose. Sucralose, which is 600 times sweeter desk sugar, is fitted to cooking, baking, and mixing with acidic foods. It’s offered under the model identify Splenda.


Many types of artificial sweeteners exist, but not all are authorized to be used in every nation. The most common ones include aspartame, sucralose, saccharin, neotame, and acesulfame potassium.

Artificial sweeteners, urge for food, and weight

Artificial sweeteners are popular amongst individuals who’re trying to lose weight.

However, their results on urge for food and weight range amongst studies.

Effects on urge for food

Some people imagine that artificial sweeteners would possibly increase urge for food and promote weight gain (5Trusted Source).

The thought is that artificial sweeteners could also be unable to activate the food reward pathway wanted to make you’re feeling glad after you eat (6Trusted Source).

Given that they taste sweet but lack the calories found in different sweet-tasting foods, they’re thought to confuse the brain into still feeling hungry (7Trusted Source8Trusted Source).

Additionally, some scientists suppose you’d have to eat extra of an artificially sweetened food, compared with the sugar-sweetened model, to really feel full.

It’s even been advised that sweeteners might cause cravings for sugary foods (5Trusted Source9Trusted Source10Trusted Source11Trusted Source).

That said, many latest studies don’t assist the concept that artificial sweeteners increase hunger or calorie intake (12Trusted Source13Trusted Source).

In reality, a number of studies have found that participants report less hunger and consume fewer calories after they substitute sugary foods and beverages with artificially sweetened options (14Trusted Source15Trusted Source16Trusted Source17Trusted Source18Trusted Source).


Recent studies have found that changing sugary foods or drinks with artificially sweetened ones might reduce hunger and calorie intake.

Effects on weight

Regarding weight control, some observational studies report a link between consuming artificially sweetened beverages and obesity (19Trusted Source20Trusted Source).

However, randomized managed studies — the gold commonplace in scientific analysis — report that artificial sweeteners might reduce body weight, fat mass, and waist circumference (21Trusted Source22Trusted Source).

These studies also present that changing common soft drinks with sugar-free variations can lower body mass index (BMI) by as much as 1.3–1.7 factors (23Trusted Source24Trusted Source).

What’s extra, selecting artificially sweetened foods instead of these with added sugar might reduce the number of each day calories you consume.

Various studies starting from 4 weeks to 40 months present that this may increasingly result in weight loss of as much as 2.9 pounds (1.3 kg) (13Trusted Source25Trusted Source26Trusted Source).

Artificially sweetened drinks might be an easy various for many who regularly consume smooth drinks and need to lower their sugar consumption.

However, choosing diet soda won’t result in any weight loss in case you compensate by eating bigger parts or extra sweets. If diet soda will increase your cravings for sweets, sticking to water may be best (27Trusted Source).


Replacing sugar-containing foods and beverages with artificially sweetened ones might assist you lose some weight.

Artificial sweeteners and diabetes

Those with diabetes might benefit from selecting artificial sweeteners, as they provide a sweet taste with out the accompanying rise in blood sugar levels (18Trusted Source2829Trusted Source).

However, some studies report that drinking diet soda is related to a 6–121% better risk of developing diabetes (30Trusted Source31Trusted Source32Trusted Source).

This could appear contradictory, but it’s important to note that every one of the studies have been observational. They didn’t show that artificial sweeteners cause diabetes, only that people prone to develop sort 2 diabetes also prefer to drink diet soda.

On the opposite hand, many managed studies present that artificial sweeteners don’t have an effect on blood sugar or insulin levels (33Trusted Source34Trusted Source35Trusted Source36Trusted Source37Trusted Source38Trusted Source).

Thus far, only one small research in Hispanic ladies found a negative impact.

Women who drank an artificially sweetened drink before consuming a sugary drink had 14% larger blood sugar levels and 20% larger insulin levels, compared with those that drank water before consuming a sugary drink (39Trusted Source).

However, the participants weren’t used to drinking artificially sweetened drinks, which can partially clarify the results. What’s extra, artificial sweeteners might have totally different results relying on people’s age or genetic background (39Trusted Source).

For instance, analysis shows that changing sugar-sweetened beverages with artificially sweetened ones produced stronger results amongst Hispanic youth (40Trusted Source).

This may very well be related to the surprising impact seen on Hispanic ladies above.

Although analysis results haven’t been unanimous, the present proof is mostly in favor of artificial sweetener use amongst these with diabetes. Still, extra analysis is required to judge their long-term results in totally different populations.


Artificial sweeteners may help these with diabetes reduce their intake of added sugar. However, extra analysis is required on the effects of artificial sweeteners in various populations.

Artificial sweeteners and metabolic syndrome

Metabolic syndrome refers to a cluster of medical conditions, including high blood pressure, high blood sugar, extra belly fat, and irregular cholesterol levels.

These conditions increase your risk of chronic disease, such as stroke, heart disease, and sort 2 diabetes.

Some studies counsel diet soda drinkers might have as much as a 36% larger risk of metabolic syndrome (41Trusted Source).

However, higher-quality studies report that diet soda both has no impact or a protecting one (42Trusted Source43Trusted Source44Trusted Source).

One latest research had people with weight problems and extra weight drink both 1 / 4 gallon (1 liter) of common soda, diet soda, water, or semi-skimmed milk every day.

By the tip of the six-month research, these drinking the diet soda weighed 17–21% much less, had 24–31% much less belly fat, 32% lower cholesterol levels, and 10–15% lower blood pressure, compared with these drinking common soda (44Trusted Source).

In reality, drinking water provided the same benefits as drinking diet soda (44Trusted Source).


Artificial sweeteners are unlikely to increase your risk of metabolic syndrome. Replacing sugary drinks with artificially sweetened ones would possibly lower your risk of a number of medical conditions.

Artificial sweeteners and gut health

Your gut bacteria play an important role in your health, and poor gut health is linked to quite a few issues.

These include weight gain, poor blood sugar control, metabolic syndrome, a weakened immune system, and disrupted sleep (45Trusted Source46Trusted Source47Trusted Source48Trusted Source49Trusted Source50Trusted Source).

The composition and perform of gut bacteria range by individual and are affected by what you eat, including certain artificial sweeteners (51Trusted Source52Trusted Source).

In one research, the artificial sweetener saccharin disrupted gut bacteria balance in 4 out of seven healthy participants who weren’t used to consuming them.

The 4 “responders” also confirmed poorer blood sugar control after as few as 5 days after consuming the artificial sweetener (53Trusted Source).

What’s extra, when gut bacteria from these people have been transferred into mice, the animals also developed poor blood sugar control (53Trusted Source).

On the opposite hand, the mice implanted with the gut bacteria from “non-responders” had no changes in their potential to control blood sugar levels (53Trusted Source).

Although fascinating, extra studies are wanted before strong conclusions might be made.


Artificial sweeteners might disrupt the balance of gut bacteria in some people, which might increase the risk of disease. However, extra studies are wanted to verify this impact.

Artificial sweeteners and most cancers

Since the Nineteen Seventies, debate about whether or not there’s a link between artificial sweeteners and most cancers risk has raged.

It was ignited when animal studies found an increased risk of bladder most cancers in mice fed extraordinarily high amounts of saccharin and cyclamate (54Trusted Source).

However, mice metabolize saccharin in another way than people.

Since then, more than 30 human studies have found no link between artificial sweeteners and the risk of developing most cancers (1Trusted Source55Trusted Source56Trusted Source57Trusted Source).

One such research followed 9,000 participants for 13 years and analyzed their artificial sweetener intake. After accounting for different factors, the researchers found no link between artificial sweeteners and the risk of developing various types of most cancers (55Trusted Source).

Furthermore, a latest evaluation of studies revealed over an 11-year interval didn’t discover a link between most cancers risk and artificial sweetener consumption (58Trusted Source).

This subject was also evaluated by U.S. and European regulatory authorities. Both agreed that artificial sweeteners, when consumed in beneficial amounts, don’t increase most cancers risk (1Trusted Source59).

One exception is cyclamate, which was banned to be used in the United States after the unique mouse-bladder-cancer research was revealed in 1970.

Since then, in depth studies in animals have failed to point out a most cancers link. However, cyclamate was by no means re-approved to be used in the United States (1Trusted Source).


Based on the present proof, artificial sweeteners are unlikely to increase the risk of most cancers in people.

Artificial sweeteners and dental health

Dental cavities — also often called caries or tooth decay — happen when the bacteria in your mouth ferment sugar. Acid is produced, which might damage tooth enamel.

Unlike sugars, artificial sweeteners don’t react with the bacteria in your mouth. This means they don’t kind acids or cause tooth decay (60Trusted Source).

Research also shows that sucralose is much less prone to cause tooth decay than sugar.

For this motive, the Food and Drug Administration (FDA) permits products containing sucralose to assert that they reduce tooth decay (60Trusted Source61Trusted Source).

The European Food Safety Authority (EFSA) states that every one artificial sweeteners, when consumed in place of sugar, neutralize acid and assist prevent tooth decay (28).


Artificial sweeteners, when consumed instead of sugar, lower the chance of tooth decay.

Aspartame, headaches, depression, and seizures

Some artificial sweeteners might cause disagreeable signs, such as headaches, depression, and seizures in some individuals.

While most studies discover no link between aspartame and headaches, with two noting that some people are extra delicate than others (62Trusted Source63Trusted Source64Trusted Source65Trusted Source66Trusted Source).

This individual variability might also apply to aspartame’s results on depression.

For instance, people with mood disorders could also be extra prone to expertise depressive signs in response to aspartame consumption (67Trusted Source).

Finally, artificial sweeteners don’t increase most people’s seizure risk. However, one research reported increased brain activity in children with absence seizures (68Trusted Source69Trusted Source70Trusted Source).


Artificial sweeteners are unlikely to cause headaches, depression, or seizures. However, some individuals may very well be extra delicate to those results than others.

Safety and side results

Artificial sweeteners are typically thought-about protected for human consumption (1Trusted Source).

They are carefully examined and regulated by U.S. and worldwide authorities to ensure they’re protected to eat and drink.

That said, some people should keep away from consuming them.

For instance, individuals with the uncommon metabolic disorder phenylketonuria (PKU) can not metabolize the amino acid phenylalanine, which is found in aspartame. Thus, these with PKU should keep away from aspartame.

What’s extra, some people are allergic to sulfonamides — the category of compounds to which saccharin belongs. For them, saccharin might result in breathing difficulties, rashes, or diarrhea.

Additionally, rising proof indicates certain artificial sweeteners like sucralose reduce insulin sensitivity and have an effect on the gut bacteria (71Trusted Source72Trusted Source).


Artificial sweeteners are typically thought-about protected but should be prevented by people who’ve phenylketonuria or are allergic to sulfonamides.
