The Evidence Supports Artificial Sweeteners Over Sugar

In the last few years, I’ve watched a continuing battle among my friends about which is worse for you: artificial sweeteners or sugar. Unless you want to forgo all beverages that are sweet, you’re going to run into one of these. Rather than rely on anecdote or myth, we can inform this debate with research.

The available evidence points to the fact that there appears to be a correlation between sugar consumption and health problems; none can be detected with artificial sweeteners.

Let’s start with artificial sweeteners. These have, for decades, been attacked as harmful chemicals. But everything is a “chemical,” and not all of them are bad for us. One of the oldest artificial sweeteners is saccharin. Starting in the 1980s, Congress mandated that any product containing it be accompanied by the following: “Use of this product may be hazardous to your health. This product contains saccharin, which has been determined to cause cancer in laboratory animals.” [...]

Based on these newer studies, saccharin was removed from the carcinogen list in 2000. But by that time, opinions were set. It did little to make anyone feel safe. [...]

It is true that people with phenylketonuria, a rare genetic disorder, need to limit their consumption of aspartame, since phenylalanine is one of its components. But for most people, aspartame isn’t a concern, even outside of cancer. It’s also true that some of the sugar alcohol sweeteners, like sorbitol or mannitol, can have a laxative effect or cause bloating when eaten in large amounts by some people. In normal use by most people, though, all of the approved artificial sweeteners are safe.

But what about sugar? We should acknowledge that when I, and many others, address sugar in contexts like these, we are talking about added sugars, not the naturally occurring sugars or carbohydrates you find in things like fruit. Those are, for the most part, not the problem. Added sugars are. [...]

When I argue these facts with my friends, they want to know if I put my money where my mouth is. I do. My wife and I limit our children’s consumption of soda to around four to five times a week. When we let them have soda, it’s almost always caffeine-free, because we want them to sleep. It’s also almost always sugar-free. There’s a potential, and probably real, harm from consuming added sugars; there are most likely none from artificial sweeteners.
