It all makes sense.  Sugar is the enemy!  It is high in calories and short on nutrition.  And in this generation of type two diabetes, who wants the white powdery stuff around anyway?  Yes, it makes perfect sense – find a substitute for sugar and use it to sweeten beverages, desserts, yogurts and puddings.  It cuts the amount of calories you consume per food item and it should go a long way to solving the epidemic of overweight and obesity.  Sounds good, right? But guess what? It isn’t working! 

Artificial sweeteners not only aren’t helping people lose weight; a recent study conducted at Harvard Medical School using the Framingham Heart Study shows that consuming diet drinks may actually increase the risk of heart disease.  Ravi Dhingra, M.D. and her colleagues looked at nearly 6,000 middle-aged men and women who had medical examinations every four years.  Those who consumed more than one diet or regular soda per day experienced a 25% increased risk of impaired fasting glucose and high triglyceride levels.  They had a 31% greater chance of becoming obese, a 32% higher chance of low HDL levels (good cholesterol), and a 44% increased risk of metabolic syndrome.   

So the question is: how does something that has less calories cause you to become obese and put your cardiovascular health at risk?  Several theories abound, but the overall consensus is that artificial sweeteners may actually encourage you to partake of more servings of food or drinks than would sugar.  It appears, from studies conducted on animals, that sugar actually substitutes may interfere with the body’s natural ability to count calories based on the food’s sweetness.  Additionally, many foods containing sugar substitutes may still be high in fat and total calories.  But because we see that it is sugar-free, we eat more of it.  In short, at the end of the day, it encourages our sweet tooth, causing us to consume more calories. 

What are these sweeteners and just how sweet are they?  Aspartame, an example of which is NutraSweet, is 200 times sweeter than sugar.  Saccharin, which is marketed as Sweet ‘n Low (among others brands) is also 200 times sweeter than sugar. One of the more popular sweeteners today is Sucralose, which we see on the shelves as Splenda. It is 600 times sweeter than sugar.  Although all of these sweeteners have been approved for use and have been determined as safe, their continued use has been shown to be problematic.  It should be noted that the Center for Science in the Public Interest, citing a study done by the National Cancer Institute, still maintains that saccharin in heavy amounts causes cancer of the bladder.  And there are certain sweeteners which are known to cause bloating and stomach discomfort as well.   

In all, what we DO know is that eating real food is a better way to lose weight.  Whole foods, such as whole grains and breads, tend to fill you up more and lengthen the amount of time before you feel hungry again.  Diet products almost always tend to leave you wanting more, and if you want more, you will take more, because after all, it’s meant for people who are dieting!  So remember: just because a certain food is marketed as a “diet” product doesn’t mean it will help you lose weight. 

The bottom line: consuming wholesome, healthy foods as opposed to those containing artificial sweeteners will more likely keep you thin, help you avoid heart disease and will “add hours to your day, days to your year and years to your life.”
