Is Splenda® Harmful or Safe?

The Potential Dangers of Sucralose (Splenda) - reprinted from Mercola.com

"McNeil Nutritionals, in their marketing pitch for Splenda emphasizes that Splenda has endured some of the most rigorous testing to date for any food additive. Enough so to convince the average consumer that it is in fact safe. They claim that over 100 studies have been conducted on Splenda. What they don"t tell you is that most of the studies are on animals.

Additional Concerns About Splenda Studies

There have been no long-term human toxicity studies published until after the FDA approved sucralose for human consumption. Following FDA approval a human toxicity trial was conducted, but lasted only three months, hardly the length of time most Splenda users plan to consume sucralose. No studies have ever been done on children or pregnant women.

Much of the controversy surrounding Splenda does not focus just on its safety, but rather on its false advertising claims. The competition among sweeteners is anything but sweet. The sugar industry is currently suing McNeil Nutritionals for implying that Splenda is a natural form of sugar with no calories.

Is It REALLY Sugar?

There is no question that sucralose starts off as a sugar molecule, it is what goes on in the factory that is concerning. Sucralose is a synthetic chemical that was originally cooked up in a laboratory. In the five step patented process of making sucralose, three chlorine molecules are added to a sucrose or sugar molecule. A sucrose molecule is a disaccharide that contains two single sugars bound together; glucose and fructose.


The chemical process to make sucralose alters the chemical composition of the sugar so much that it is somehow converted to a fructo-galactose molecule. This type of sugar molecule does not occur in nature and therefore your body does not possess the ability to properly metabolize it. As a result of this "unique" biochemical make-up, McNeil Nutritionals makes it"s claim that Splenda is not digested or metabolized by the body, making it have zero calories.

It is not that Splenda is naturally zero calories. If your body had the capacity to metabolize it then it would no longer has zero calories.


How Much Splenda is Left In Your Body After You Eat It?

If you look at the research (which is primarily extrapolated form animal studies) you will see that in fact 15% of sucralose is absorbed into your digestive system and ultimately is stored in your body. To reach a number such as 15% means some people absorb more and some people absorb less. In one human study, one of the eight participants did not excrete any sucralose even after 3 days. Clearly his body was absorbing and metabolizing this chemical. That is what our bodies are supposed to do.

The bottom line is that we all have our own unique biochemical make-up. Some of you will absorb and metabolize more than others. If you are healthy and your digestive system works well, you may be at higher risk for breaking down this product in your stomach and intestines. Please understand that it is impossible for the manufacturers of Splenda to make any guarantees based on their limited animal data.


If you feel that Splenda affects you adversely, it is valid. Don"t let someone convince you that it is all in your head. You know your body better than anyone else."
