-- Results Add to Evidence that SPLENDA® is Safe for People with Diabetes –

(Ft. Washington, PA, March 18, 2014) -- Consuming sucralose in a drink is shown to have the same effect as water on a person’s sugar and insulin levels, according to a study reported in Diabetes Care, a journal of the American Diabetes Association1. Sucralose is the no calorie sweetening ingredient in SPLENDA® Sweetener Products.

The study was led by Tongzhi Wu, MD, PhD, at the University of Adelaide School of Medicine, and funded by the National Health and Medical Research Council in Australia. The results showed that neither sucralose alone, or when combined with another no calorie sweetener, acesulfame potassium (AceK), had any effect on insulin secretion or blood sugar.

In the study, Wu and his team followed ten healthy men who drank four different drinks on four different occasions after an overnight fast. The four drinks were water; water with sucralose; water with AceK; and water with both sucralose and AceK. Ten minutes later each one drank a sugar solution.

The participant’s sugar, insulin, and GLP-1 blood levels were measured before, and for six hours after, drinking the sugar solution. (GLP-1 is a hormone known to slow gastric emptying and has a role in appetite regulation.) The results showed no differences in outcomes for any of these measures, whether the men drank plain water, or water sweetened with either or both sweeteners. It should be noted that using all men in such a study is a way to minimize the possibility of effects unrelated to testing. For example, hormonal changes that can occur with menstruation can influence insulin levels2,3 .

“Our findings are … consistent with previous reports…” the authors state, and they concluded that “… sucralose and AceK, either alone or in combination, have no acute effect on gastric emptying, GLP-1, or glycemic responses after oral glucose in healthy humans.”

In their comments in Diabetes Care1, Dr. Wu and colleagues point out that a previous study reported that drinking diet soda increased GLP-1 levels. This result was further interpreted to mean that the artificial sweeteners could potentially impact metabolism and increase a person’s sugar levels.

In contrast, Dr. Wu noted that, “The design of that study was, however, suboptimal, as the diet soda contained a number of substances (including caramel color, gum acacia, natural flavors, citric acid, potassium benzoate, phosphoric acid, and potassium citrate) that were not controlled for.” Consequently, Dr. Wu and his team chose to give participant’s in their study sweeteners in water to avoid the potential effect of these other substances on glucose, insulin or GLP-1.

“The Wu study provides more evidence that SPLENDA® can be used safely by everyone, including pregnant women, children and people with diabetes,” says Maureen Conway, R.D., Director of Nutritional Affairs for McNeil Nutritionals, LLC. “This is especially meaningful for people with diabetes and their caregivers. Foods and beverages sweetened with SPLENDA® No Calorie Sweetener can be a great way for people to enjoy the foods they love as part of their diabetes meal plan. And using SPLENDA® with regular physical activity can be an excellent way to help with weight management.”

Sucralose, the no calorie ingredient in SPLENDA® Sweetener Products, is not sugar and the body does not recognize it as such. Unlike sugar, sucralose is not broken down for energy. It is not a source of carbohydrate or glucose, and clinical studies have shown it has no effect on blood glucose levels, insulin secretion or blood levels, glycosylated hemoglobin levels (HbA1c), or blood glucose control.

SPLENDA® Sweetener Products have been used safely by millions of people around the world for more than 20 years, supported by research data from more than 110 studies. Both the American Diabetes Association (ADA) and the Academy of Nutrition and Dietetics (AND) support the use of low calorie sweeteners such as sucralose as a useful tool in managing weight and diabetes.

Statement on Schiffman Sucralose Overview Paper

A recent paper from Schiffman et al. on sucralose, the sweetening ingredient in SPLENDA® Sweetener Products, does a disservice to consumers who use sucralose as a safe and effective tool in managing their weight or diabetes. The paper is a reiteration of assertions Schiffman has made before, based largely on a study from 2008 (Abou-Donia An expert panel report1 later found that the Abou-Donia study was deficient in several areas and the conclusions were not consistent with published literature or the data presented.

SPLENDA® has been used safely by millions of people around the world for more than 20 years and consumers can continue to have confidence in their choice of SPLENDA®. Global health authorities have reviewed more than 110 studies on sucralose and agree that it can be used safely by everyone. Both the American Diabetes Association (ADA) and the Academy of Nutrition and Dietetics (AND) support the use of sucralose as a useful tool in managing weight and diabetes. Additionally, in 2012, international experts in food safety, health and nutrition held a conference in Italy to reassess the safety of no and low calorie sweeteners, including sucralose. They endorsed previous regulatory conclusions that all approved low and no calorie sweeteners “are perfectly safe.” 2

SPLENDA® Brand Sweetener and Weight Management
September 2013

Quite a bit of misinformation has been circulating about low-calorie sweeteners, including questions about their use in weight management. However, the overall data shows that low-calorie sweeteners can be useful in strategies for weight management.

We encourage people to make informed choices about using SPLENDA® Brand Sweetener by reviewing the credible research available on sucralose (the no-calorie sweetening ingredient in all SPLENDA® Sweetener Products) and on low-calorie sweeteners in general.

The breadth of scientific research does not support the theory that low-calorie sweeteners cause people to gain weight or increase their appetite. In fact, studies of persons using low-calorie sweeteners show that low-calorie sweeteners can be useful in weight management strategies.

Additionally, rigorous large lifetime studies of rats that received amounts of sucralose comparable in sweetness to over 40 pounds of sugar per day showed that sucralose does not cause increases in body weight. Overall, there is a significant range of data that supports sucralose and other low-calorie sweeteners as positive tools in sensible weight management strategies.

Professional organizations including the Academy of Nutrition and Dietetics support these conclusions, and the American Diabetes Association (ADA) offers this advice: “As part of a weight loss or weight management plan, artificial sweeteners can provide low-calorie options for desserts and other treats instead of cutting them out completely.”

The theory that low-calorie sweeteners can contribute to weight gain by tricking the body to crave more calories is not supported by overall research. In fact, low-calorie sweeteners have been shown to be useful in weight loss programs.

While newer studies have sent some confusing messages, it is important to know that not all new studies, or the headlines that sometimes accompany them, are designed to actually assess cause and effect. For example, many of the recent articles on low-calorie sweeteners are from observational studies. These are studies that can show certain associations, but cannot test for cause and effect. In contrast, studies designed to test cause and effect show no evidence that low-calorie sweeteners cause weight gain. This is not at all surprising, since intake of these sweeteners provides little or no nutrients that can be stored as energy for weight gain.

Consumers should always take a practical, balanced approach toward weight management. SPLENDA® No Calorie Sweetener is not the single answer to a healthier lifestyle, nor is it a cure for obesity. But it can be an easy way to help reduce the daily intake of calories and carbohydrate from added sugars – without sacrificing taste. It’s one of many small changes people can make in their daily routines that can add up to meaningful changes in their weight management efforts over time.

Statement on Sucralose and the Center for Science in the Public Interest (CSPI)

Recently, the Center for Science in the Public Interest (CSPI) made comments about the safety of sucralose. Their comments were based on pending data from an Italian research lab. That data has not been published and, to our knowledge, has not been peer reviewed, which is a critical step in validating research. Previous studies from this lab have been questioned by international food safety authorities, partly because the researchers did not follow accepted standards for assessing safety.1

In contrast, more than 110 studies conducted over 20 years have proven the safety of sucralose, the sweetening ingredient in SPLENDA® Sweeteners. Worldwide authorities, including the U.S. Food and Drug Administration, the European Food Safety Authority, Health Canada, and the World Health Organization, have reviewed these studies and confirm that results show no link between sucralose and any form of cancer. The National Cancer Institute (NCI) and the American Cancer Society (ACS) are among numerous health organizations that support this conclusion1.

SPLENDA® Sweeteners have been enjoyed safely by millions of people around the world and are an excellent tool for people looking to reduce added sugar in their diet. The American Diabetes Association and the Academy of Nutrition and Dietetics both support that sucralose can be a useful tool in managing weight and diabetes. People can continue to use SPLENDA® safely and we urge anyone with questions about using SPLENDA® Sweeteners to speak with a healthcare professional

Statement on Washington University/Pepino Study
June 2, 2013

People who use SPLENDA® Brand Sweetener (sucralose) should not be misled by the recent study from Washington University on sucralose and its potential to affect the body's sugar levels. This small study in morbidly obese people does not reflect the extensive body of science that shows sucralose is safe and can be used by everyone, including people with diabetes. SPLENDA® has been available for more than 20 years and has been used by millions of people around the world, and rigorous research has shown that it does not raise people’s sugar or insulin levels. The American Diabetes Association and the Academy of Nutrition and Dietetics both support the role of sucralose as a useful tool in managing weight and diabetes. People can continue to use SPLENDA® safely and we urge anyone with questions about using SPLENDA® to speak with their health care professional. Here is more important information about the study:

  • The study was of short duration (two separate test days, one week apart) and involved people who did not have diabetes.
  • The study looked at how the participants responded to a sugar-sweetened drink consumed immediately after drinking water or water containing sucralose. It is normal for blood sugar levels to rise after consuming a sugar-sweetened drink, whether or not sucralose was consumed beforehand.
  • The researchers did not point out that even the highest sugar level observed in the participants is considered to be normal, based on normal ranges set by health care professionals. This means no clinical significance can or should be drawn from the differences observed between the two people who drank unsweetened water, compared to those who drank water with sucralose.
  • Moreover, researchers did not control for conditions that could have affected the participants' response to the sugar test drinks -- such as diet or exercise -- in the days before each of the two testing days. Changes in exercise can particularly affect insulin responses.
  • The study involved people who were morbidly overweight (avg BMI = 41), which could affect the way their bodies respond to consuming sugar. It's common for people with extreme obesity to have a different response to sugar than people of normal weight.
  • Importantly, more than 120 studies over a 20-year period have demonstrated that sucralose is a safe sweetener that can be used by everyone, including children, women who are pregnant or nursing, and people with diabetes. These studies included clinical trials in people with Type 1 and Type 2 diabetes and in people without diabetes, where sucralose was consumed in high doses for months. The total evidence shows that sucralose has no negative effects on blood sugar levels, insulin, or hemoglobin A1c (a measure of long-term blood glucose control).

Sucralose and the Environment

Sucralose, the sweetening ingredient in SPLENDA® Sweetener Products, has been rigorously tested to meet U.S. and international regulations necessary for approving a food ingredient for use in the general population. Over 120 studies have been conducted to demonstrate that sucralose can be used safely by all populations, including children, women who are pregnant or nursing, and people with diabetes. Additionally, studies have been done to study the potential for environmental impact and the results showed that sucralose is safe in the environment and does not bioaccumulate in animals or plants.

Specifically, the U.S. Food and Drug Administration (FDA) reviewed numerous studies conducted to investigate the potential for environmental impact, before approving sucralose for marketing in the U.S. In the FDA's initial approval of sucralose as a food additive, the FDA stated:

"The agency has carefully considered the potential environmental effects of this action. FDA had concluded that the action [approval of sucralose] will not have a significant impact on the human environment, and that an environmental impact statement is not required." (Federal Register, Vol. 63, No. 64, Friday, April 3, 1998, Rules and Regulations, page 16431).

Additionally, as part of the regulatory approval process for sucralose, a comprehensive range of scientific studies on sucralose was conducted to investigate the potential impact on plant and aquatic life. The data was submitted to regulatory agencies around the world, including Canada, the European Union, Japan, and Australia. All environmental studies on sucralose were conducted to internationally agreed protocols validated for regulatory purposes. Specific studies clearly demonstrate that sucralose has no adverse effect on fish, invertebrates (e.g., water flea), algae or higher plants. These studies showed no effects at concentrations of sucralose that were many times greater than would be found in the environment. Every regulatory authority who reviewed the environmental data on sucralose arrived at the same conclusion: Sucralose has no adverse effect on the environment.

Regulatory Toxicology and Pharmacology journal publishes new sucralose papers (October 2009)

The scientific journal, Regulatory Toxicology and Pharmacology, has published two articles affirming the safety of sucralose. Sucralose is the sweetening ingredient in SPLENDA® Sweetener Products and is used by millions of people worldwide to reduce their use of sugar as part of a healthier lifestyle. Both papers on sucralose appeared in the October 2009 issue of the journal (Volume 55, Issue 1).

In the paper, "Expert Panel Report on a Study of SPLENDA in Male Rats," internationally recognized experts in nutrition, weight management, toxicology, food safety, medical and public health and other relevant areas, assessed the design, results and conclusions from a small study in male rats given a retail SPLENDA® product. The study was funded by the Sugar Association and the study investigators had raised certain questions about possible adverse effects. The Expert Panel found that the study was deficient in several critical areas, had serious design flaws, and did not represent evidence of any adverse health effects of either sucralose or SPLENDA® No Calorie Sweetener. They noted that the safety data surrounding sucralose has "been rigorously evaluated by experts around the world" and that the available evidence demonstrates that Splenda and sucralose are safe. (For more information, go to:, Browse by Title, Regulatory Toxicology and Pharmacology, Vol. 55, Issue 1)

A second paper, "An Overview of the Safety of Sucralose," provides a comprehensive review of some 110 studies conducted on sucralose, including a detailed discussion of the fate of sucralose in the body and key findings with regard to sucralose safety. The article also describes the extensive reviews conducted by food safety and public health authorities from around the world, and reports that these "trained safety and health protection authorities have concluded from [the scientific] database [on sucralose], that sucralose is a safe food ingredient that can be safely consumed for a lifetime." The paper also notes that these expert independent evaluations resulted in "no limitations for use by any population subtypes," and, for example, is "safe for use by children and people with diabetes."
