Artificial Sweeteners: The Science
What are artificial sweeteners?
Artificial sweeteners or Low-calorie sweeteners (LCS) are synthetic sugar substitutes up to 8000 times sweeter than sugar but with less food energy. They are metabolized more slowly than sugar which allows for stabilization of sugar levels.
The FDA has approved 6 artificial sweeteners
- saccharin (Sweet ‘N Low)
- acesulfame (Sunett)
- aspartame (Equal)
- tagatose and sucralose (Splenda)
- a natural low-calorie sweetener (Stevia)
A word on Stevia…
Although considered a natural alternative, Stevia is not free of adverse effects. It has been associated with decreased sperm production and infertility in animal models. Research in humans is ongoing.
- Research on the long-term effects of artificial sweeteners use is ongoing.
- Rare or delayed effects of the newer LCS’s may not been identified yet.
- In children, the use of these types of additives should only be considered when other strategies have been tried
- For weight and glycemic control benefits, the use of artificial sweeteners must be combined with lifestyle modifications including healthy diet and increased in exercise.
- Eat less sugar. It’s a no-brainer.
- There’s no question that artificial sweeteners contain fewer calories than sugar.
- Artificial sweeteners may have a stimulating effect on appetite and, therefore, may play a role in weight gain and obesity.
- Cut back on foods with added sugar and you can reduce cravings for sugar in the first place.
