Learn how artificial sweeteners are becoming more popular Understand how they affect appetite regulation of your body Learn their significance on weight management Know the potential hazards that are associated with artificial sweeteners
The obesity epidemic is linked to high dietary intakes of sucrose and fructose. ◦ Insulin resistance can result, which can lead to diabetes, metabolic syndrome, heart disease, and stroke. Artificial sweeteners have little to no calories, so they are a tempting choice over sugar. They are being increasingly added to processed foods (they’re in cosmetics too). ◦ More foods are labeled as “diet” or “light” As of 2007, 86% of Americans use low-calorie, reduced sugar, or sugar-free foods and beverages.
Sucralose (Splenda)* Aspartame (Equal, Nutrasweet)* Saccharin (Sweet ‘N Low)* Neotame Acesulfame-K * = Most commonly used
Does the sweetness of artificial sweeteners make you eat more? ◦ Adults No significant differences compared to sucrose on hunger stimulation. ◦ Children Complete energy compensation was seen in comparison to sucrose. What about glucose metabolism? ◦ No significant changes on insulin, glucagon, or blood glucose levels. ◦ Ghrelin levels decreased with sucrose, meaning it responds to energy intake.
Currently, there is not enough scientific evidence to support that artificial sweeteners are beneficial to weight loss. ◦ Studies show a modest to no change in weight. Dependent on other factors ◦ Lifestyle ◦ Physical activity
Are there carcinogenic risks? ◦ The FDA approved them to be safe for general use. Most artificial sweeteners are not metabolized by the body. One exception is aspartame, which is broken down in the body, yielding 4 kcal/g. Studies of potential toxicity ◦ Migraines were reported in mild cases. ◦ Certain cancers (bladder and mammary), DNA damage, lymphomas, and leukemias were seen in rats. Can results from animals be translated to humans?
The rise of obesity will cause more people to turn to artificial sweeteners to replace sugar in an effort to control their weight. Artificial sweeteners alone will not cause weight loss. A restricted calorie plan and increased physical activity should be followed through to produce results. It is impossible to completely avoid artificial sweeteners, but they should be restricted based on potential health risks.
Which artificial sweetener is completely broken down in the body? ◦ Aspartame True or false: The side effects of artificial sweeteners have been heavily researched in humans. ◦ False
