Is Sucralose Bad?

Sucralose is an FDA-approved artificial sweetener. It’s a chlorinated sugar composed of sugar and chlorine. Sucralose may cause cancer in specific individuals. The chemical damages DNA, causing illnesses including diabetes, Alzheimer’s, and Parkinson’s.

It may induce gastrointestinal distress, weight gain, and depression.


Many of our friends and family members believe artificial sweeteners like Splenda may treat diabetes and prevent obesity. However, the ingredients in Splenda, also known as Sucralose, are related to many health problems. A closer look at the specifics reveals further adverse effects.

Sucralose is a common artificial sweetener used in low-calorie foods and beverages. However, despite its promotion as a better choice for your figure, the many sucralose side effects and dangers cannot be ignored.

Avoid sugar substitutes that lack antioxidants, vitamins, minerals, and fiber, and choose sugar substitutes that do.

What Is Sucralose?

Sucralose is a chlorinated sucrose derivative. This indicates that it is made of sugar and includes chlorine.

Sucralose is made by replacing the three hydrogen-oxygen groups of sugar with chlorine atoms in a multistep process. The addition of chlorine atoms enhances Sucralose’s sweetness.

Sucralose was discovered by accident while developing a new pesticide chemical. It was never intended to be eaten.

However, it was subsequently marketed to the general public as a “natural sugar replacement,” and most people were unaware that it was poisonous.

Sucralose was authorized by the Food and Drug Administration (FDA) in 1998 for use in 15 food and beverage categories, including baked goods, frozen dairy desserts, chewing gum, drinks, and sugar replacements. The FDA then extended its approval in 1999, allowing it to be used as a general-purpose sweetener in all types of foods and drinks.

Splenda Information

Splenda is the most popular sucralose-based product on the market today. In the United States, it is one of the most widely used sweeteners.

That’s most likely because it’s 600 times sweeter than sugar. Here are some generic Splenda facts that may help you decide whether or not to use it:

  • Splenda is a sugar substitute that the body does not recognize.
  • Sucralose makes up just around 5% of Splenda. The remaining 95 percent is made up of a filler called maltodextrin and corn-based dextrose, a kind of sugar.
  • Splenda is a sugar replacement used in cooking and baking and hundreds of “zero-calorie” foods marketed throughout the United States.
  • Splenda has a calorie value of 3.36 calories per gram, which originates from dextrose and maltodextrin.

According to data, Sucralose is used in a wider variety of products worldwide than any artificial sweetener.

Why is Sucralose so widely used in foods and beverages? It dissolves well in ethanol, methanol, and water.

As a result, it may be utilized in both fat- and water-based goods, as well as alcoholic beverages.

Aspartame and sodium saccharin, for example, are less soluble artificial sweeteners. As a result, their product applications are more restricted.

Dangers and Side Effects

1. Has the potential to cause diabetes

According to research published in the journal Diabetes Care, those who eat Sucralose have a far higher chance of getting diabetes. Diet Coke intake was linked to a 36 percent increased risk of metabolic syndrome and a 67 percent increased risk of type 2 diabetes in the research.

Sucralose is, therefore, one of the accidental diabetes causes. So, if you’re asking whether Sucralose is safe for diabetics, the obvious answer is no – it increases your chance of developing the disease.

For the first time, researchers tested this phenomenon on human volunteers. Seventeen insulin-sensitive obese people were given oral glucose tolerance tests after ingesting Sucralose or water.

It was found that after eating Sucralose, there was a 23 percent reduction in insulin sensitivity, which inhibits glucose absorption in cells, in addition to an “increase in peak plasma glucose concentrations.”

Sucralose intake in the presence of a carbohydrate affected glucose metabolism quickly, resulting in disruption of the gut-brain control of glucose metabolism, according to research published in Cell Metabolism in 2020.

2. Irritable Bowel Syndrome and Crohn’s Disease are more likely to occur

Sucralose consumption promotes IBS symptoms, ulcerative colitis, and Crohn’s disease, according to New Jersey Medical School researcher Xin Qin, M.D., Ph.D. After studying the significant rise of IBS among Alberta residents over 20 years, Dr. Qin discovered this. In other words, it increased by 643 percent.

This prompted Qin to undertake his research. What did he discover?

Because 65 percent to 95 percent of Sucralose is excreted unaltered in the feces, it has a more significant negative impact on gut flora than other artificial sweeteners like saccharin. Canada was the first nation in the world to approve Sucralose as an artificial sweetener in 1991. In other words, there was a direct link between sucralose use and increased inflammatory bowel illness.

According to new research published in Inflammatory Bowel Diseases, Artificial sweeteners like Splenda increase the risk of Crohn’s disease and may worsen antimicrobial intestinal reactivity in people with Crohn’s and other pro-inflammatory conditions.

To address some frequently asked concerns about Sucralose’s safety and digestion – can Sucralose induce bloating? It has been connected to severe pro-inflammatory diseases that impact your digestive system. Therefore it most definitely may.

Is Sucralose causing you to poop? In rare instances, it may promote inflammation and induce IBS symptoms.

3. It’s linked to Leaky Gut Syndrome

What effect does Sucralose have on gut bacteria? Essentially, we now know that since The human body cannot digest Sucralose, it travels through the gastrointestinal tract, causing harm as it goes. For example, it damages the intestinal wall, leading to a leaky gut.

Sucralose’s adverse effects on gut health have been proven in many research. For example, a Duke University Medical Center animal research published in the Journal of Toxicology and Environmental Health found that Splenda decreases beneficial bacteria in the stomach and raises fecal pH. This reduces your ability to absorb nutrients.

4. When heated, it may produce toxic (and carcinogenic) compounds

According to research published in the Journal of Toxicology and Environmental Health, Sucralose cooked at high temperatures may produce hazardous chloropropanols, a potentially poisonous family of chemicals. In addition, although Sucralose is frequently used in baked products, studies indicate that the artificial sweetener’s stability diminishes when temperature and pH rise.

When Sucralose is cooked, not only does it degrade thermally, but it also produces chloropropanols, which are a category of pollutants that include genotoxic, carcinogenic, and tumorigenic chemicals.

“Caution should be taken in the use of sucralose as a sweetening ingredient during baking of food items containing glycerol or lipids,” the researchers stated in their study published in Food Chemistry.

Whether you’re wondering if Sucralose may cause cancer, this is alarming news, mainly because Sucralose is often used in baked goods and other hot food items. However, more study is required to provide solid proof of Sucralose’s carcinogenic consequences.

5. It’s linked to gaining weight

Sucralose in your coffee was supposed to help you lose weight. However, epidemiological research in people and laboratory studies in animals points to a link between artificial sweetener use and weight increase.

Artificial sweetener usage has also been linked to an increased risk of metabolic syndrome, type 2 diabetes, hypertension, and cardiovascular disease. This research didn’t look at the effects of Sucralose on weight gain; in particular, however, some studies show Sucralose doesn’t assist with weight reduction.

641 youngsters (477 finished the research) were randomly allocated to receive an eight-ounce can consisting of either a no-calorie sweetened or a sugar-sweetened beverage with 104 calories per day in an 18-month experiment published in the New England Journal of Medicine.

There were 34 milligrams of Sucralose and 12 milligrams of acesulfame-K in the sugar-free beverage. By the conclusion of the trial, the children in the sugar-sweetened group had consumed 46,627 more calories from these drinks than the children in the sucralose-sweetened group.

However, the sugar-sweetened group’s overall weight increase throughout the 18 months was just one kilogram higher. Given the substantial variation in calorie intake from drinks, researchers are baffled as to why there is little difference in weight gain.

Another research of teenagers found no consistent decrease in weight gain two years after families were given artificially sweetened drinks in an attempt to limit their use of sugary sodas.

So, does Sucralose make you gain weight? Well, we already know that it doesn’t assist with weight reduction in many instances, and it doesn’t seem to be a successful weight-loss technique for individuals who use it in their cooking, baking, and coffee to keep track of their calories.

According to studies, Sucralose and goods containing Splenda have been linked to headaches and allergic responses. Furthermore, a new study suggests that sucralose use may harm your gut health and possibly induce metabolic syndrome.

If you use Sucralose is a no-calorie sweetener and are attempting to lose weight, studies indicate artificial sweeteners like Splenda do not seem to aid weight reduction. Instead, use natural sweeteners that are fewer in calories.

Raw honey and stevia are two great alternatives.

Foods and their Applications

Sucralose, often known as Splenda, is used in various food and beverage items promoted as healthier alternatives. However, you may not even realize Sucralose is present in the bottled beverage or packaged food you buy at the supermarket.

It’s in toothpaste, tablets, and vitamins, among other things.

The easiest method to determine whether a product contains Sucralose is to look at the ingredient label. Unfortunately, it’s very uncommon for a product’s box or bottle to state right on the front that it’s produced using Splenda.

Sucralose-containing goods are often marketed as “sugarless,” “sugarless,” “lite,” or “zero calories.” Keep an eye out for these slogans, since they typically signal the presence of an artificial sweetener in the product.

Sucralose is found in a variety of goods, including the following:

  • Some low-calorie sodas
  • A few glistening waters.
  • Diet iced teas are available.
  • A few juice items
  • Sauces, toppings, and syrups that are sugar-free
  • Gum chewing (including “sugarless” varieties)
  • Cocoa mixtures that are “diet,” “fat-free,” and “no sugar added.”
  • Protein and diet snacks, powders, and drinks are available.
  • Many “sugar-free” baked products are available.
  • Ice pops and ice cream with no added sugar
  • Ice cream with a “light” or “no sugar added” label.
  • A few popcorn items
  • Yogurt items that are “sugar-free” and “light.”
  • Hard candy that is “sugar-free” or “light.”
  • Chocolates that are “sugar-free.”
  • Mints and lozenges without sugar
  • Several toothpastes are available.

Is it secure?

The short answer is no to the question. Sucralose causes anything from metabolic syndrome to digestive issues and weight gain. In reality, smoking has a detrimental effect on your health in various ways.

What are Sucralose’s side effects? The following are only a few of the numerous Sucralose adverse effects:

  • Glucose and insulin levels are affected
  • Raises the likelihood of stomach issues
  • Affects the GI tract and changes gut health
  • Destroys probiotic bacteria
  • May have a role in the development of some malignancies
  • When heated, it produces hazardous chemicals.
  • May result in weight gain

Stevia vs. Aspartame vs. Sucralose


Sucralose is an artificial sweetener found in “sugar-free” and “sugar-free” goods. It’s advertised as a calorie-free sweetener that may help you lose weight, but studies show this isn’t the case.

Sucralose is found in various grocery store items, includingThe FDA has authorized SucraloseDA for use in food and beverage items, including those sold to children. However, there are some worries about swallowing it. In addition, it’s been related to leaky gut and gastrointestinal issues, including IBS and Crohn’s disease, according to studies.

It may even induce diabetes, even though it’s frequently promoted as a “sugar-free” agent that’s healthier for people with diabetes.

Sucralose vs. Stevia

Stevia is a herb that has been used for over 1,500 years as a sweetener. It is a natural sweetener, unlike Sucralose and aspartame.

Stevia extracts are 200 times sweeter than sugar; according to some sources, although it may be used in lieu of sugar in your morning coffee or smoothie, stevia does not have the same harmful side effects as other artificial sweeteners.

It may have anticancer, anti-diabetic, cholesterol-lowering, and weight-loss effects.

A fascinating research examines the impact of stevia, sugar, and other sweeteners on food intake, satiety, and glucose/insulin levels after meals. The study, published in the journal Appetite, included 19 healthy, lean adults and 12 obese people aged 18 to 50 who completed three tests. They drank stevia, sucrose (table sugar), or aspartame before eating lunch and supper.

It should come as no surprise that when these individuals drank stevia, they didn’t feel as hungry as they did when they consumed sugar. Furthermore, “stevia substantially decreased post-meal glucose levels compared to those who ingested sugar or aspartame,” according to the study.

In other words, scientists found that stevia helps regulate blood sugar levels and lower diabetes risk compared to the blood sugar rise that occurs when individuals consume sweet or diet drinks before, during, or after meals.

Sucralose vs. Aspartame

Aspartame is a synthetic sweetener that is also known by the brand names Equal® and NutraSweet®. It may be found in a wide range of foods and goods, such as:

  • Soda with no calories
  • Breath mints without sugar
  • Cereals with no added sugar
  • Water with a taste
  • Items for meal replacement
  • Sports beverages

Although businesses profiting from aspartame’s popularity have published papers promoting its safety, 92 percent of research financed independently show the artificial sweetener’s negative consequences. Aspartame has been linked to worsening (or maybe creating) diabetes, raising the risk of heart disease, probably causing brain problems, exacerbating mood disorders, causing weight gain, and possibly causing cancer.

Is Sucralose as harmful to your health as aspartame?

Aspartame, like Sucralose, is authorized by the FDA for use in various foods and drinks. It may be found in over 6,000 different items, including diet soda.

Even after the data on its severe side effects was published, it was still present in over 500 over-the-counter and prescription medicines.

Both artificial sweeteners have potentially harmful side effects and should be avoided at all costs. Instead, use a natural sweetener such as stevia in your coffee, baked goods, and other dishes that need the sweetness.

Better Alternatives

You don’t have to use artificial sweeteners if you want to add sweetness to your dishes in a healthy way. Several great natural sweeteners are both delicious and don’t come with a laundry list of possible negative effects and risks.

Here’s a breakdown of some of the most refined sugar substitutes available:

  1. Stevia is a natural sweetener that originates from the Asteraceae family of plants. It is known as the “sweet herb” and has been used for over a thousand years. For people with diabetes, stevia is one of the most OK sweeteners. It’s heat-resistant and may be used in baking, but keep in mind that it’s 200 times sweeter than regular sugar, so a little goes a long way.
  2. Raw honey contains enzymes, antioxidants, vitamins, and minerals and is a natural sweetener. One tablespoon has 64 calories and has a lower glycemic index than a banana. Raw honey should not be cooked with, but it may be poured over yogurt, toast, salads, or cereals to add sweetness.
  3. Maple syrup nutrition contains up to 24 distinct antioxidants, making it more antioxidant-rich than sugar. Manganese, calcium, potassium, and zinc are all found in it. In addition, unlike Sucralose, maple syrup is heat-stable and may be used in a wide variety of recipes, including cookies, cakes, glazes, and pancakes. Choose a grade B or even grade C product that is 100 percent pure organic maple syrup.
  4. Coconut sugar is made from the sap of the coconut tree that has been dried. Vitamins and minerals are present in tiny quantities. Short-chain fatty acids, polyphenols, antioxidants, and fiber are also present. Because it measures exactly like table sugar, you may use it as a sugar replacement in your favorite recipes.
  5. Blackstrap molasses is a kind of molasses made from raw sugar cane. Raw sugar is boiled until it turns into a thick, sweet syrup. Blackstrap molasses, unlike table sugar, is very healthy. It has the greatest phenolic content and antioxidant activity compared to refined sugar, rapeseed honey, and dates; therefore, baking and marinades may benefit from blackstrap molasses. When mixed with coconut sugar, it may also be used as a brown sugar substitute.


  • What is Sucralose, and is it harmful to your health? Sucralose is a sodium chloride derivative of sucrose that is used as a sugar replacement since it has no calories. However, according to research, it’s an unhealthy choice for individuals who want to use zero-calorie sweeteners.
  • Splenda, one of the most popular sweeteners in the United States, is the most prevalent sucralose-based product on the market today. Splenda has 600 times the sweetness of sugar.
  • Sucralose is found in various foods and drinks, including diet sodas and other carbonated beverages, iced teas, ice cream, ice-pops, yogurts, baked goods, chewing gum, sweets, and protein bars, in addition to packets of Splenda.
  • According to a new study, sucralose use has various negative health consequences, including the potential to add diabetes may be a result.
    • Irritable bowel syndrome (IBS) and Crohn’s disease are more likely to occur.
    • This may result in a leaky gut.
    • When heated, poisonous and carcinogenic chemicals are produced.
    • Causing you to gain weight
  • As a result, natural sweeteners like stevia, raw honey, and maple syrup are preferable.

Sucralose is a sweetener that has been used in products such as Splenda, but it can be toxic if ingested in large amounts. There are 5 reasons to avoid Sucralose and artificial sweeteners in general.
