Are sugar substitutes harmful?

Sugar Substitutes: Safety and Health Implications

Sugar substitutes are generally safe when consumed in moderation, but they offer limited health benefits and should not be viewed as a perfect solution for reducing sugar intake. 1

Safety Profile of Nonnutritive Sweeteners

Nonnutritive sweeteners (NNS) have been approved by the U.S. Food and Drug Administration (FDA) for consumption by the general public, including people with diabetes 1. The FDA has approved several NNS after rigorous scrutiny, including:

• Saccharin
• Aspartame
• Acesulfame potassium
• Sucralose
• Neotame
• Stevia (as GRAS - Generally Recognized As Safe)
• Advantame
• Monk fruit extract 1

Potential Benefits

• NNS can reduce overall calorie and carbohydrate intake when substituted for caloric sweeteners, provided there is no compensation with additional calories from other food sources 1
• For people with diabetes accustomed to consuming sugar-sweetened products, NNS may be an acceptable substitute when consumed in moderation 1
• NNS do not significantly affect glycemic management 1

Potential Concerns

• Mixed evidence regarding weight management - some studies show benefit in weight loss, while others suggest an association with weight gain 1
• No clear benefit for weight loss or reduced weight gain without energy restriction 1
• Some research suggests a possible association between higher NNS consumption and development of type 2 diabetes, though substantial heterogeneity makes interpreting results difficult 1
• Recent research raises questions about potential cardiovascular risks with long-term use 2

Recommendations for NNS Use

The most current guidelines from the American Diabetes Association (2021) suggest:

1. NNS may be used as a substitute for nutritive sweeteners when consumed in moderation 1
2. Low-calorie or nonnutritive-sweetened beverages may serve as a short-term replacement strategy for sugar-sweetened beverages 1
3. People should be encouraged to decrease both sweetened and nonnutritive-sweetened beverages over time 1
4. Emphasis should be placed on water intake as the preferred beverage 1

Special Populations

Certain populations should use NNS with particular caution:

• Pregnant and lactating women
• Children
• People with diabetes
• Individuals with migraine or epilepsy 3

Alternative Approaches to Reducing Sugar

Rather than simply substituting NNS for sugar, a more comprehensive approach to healthy eating includes:

• Emphasizing nonstarchy vegetables
• Minimizing added sugars and refined grains
• Choosing whole foods over highly processed foods 1
• Focusing on nutrient-dense food choices rather than simply replacing sugar with NNS 1

Common Pitfalls

1. Compensation effect: People may compensate for "saved" calories from NNS by consuming more calories from other sources, negating potential benefits 4

2. False sense of health: Using NNS products may create a perception that one's diet is healthier than it actually is, leading to poor overall dietary choices

3. Overlooking overall diet quality: Focusing solely on sugar reduction through NNS without addressing overall diet quality is unlikely to significantly improve health outcomes 4

4. Ignoring water as the ideal beverage: The guidelines clearly recommend water as the preferred beverage choice over both sugar-sweetened and NNS-sweetened beverages 1

In conclusion, while NNS appear safe for most people when consumed in moderation, they should be viewed as a potential short-term strategy rather than a long-term solution for reducing sugar intake. The emphasis should remain on improving overall diet quality and gradually shifting toward water as the primary beverage.
