This post is Part II of a three-part series on understanding sugars, artificial sweeteners and natural sweeteners. If you missed Part I, click here.
Most of us who consider ourselves “health-conscious” avoid regular table sugar. Instead, we reach for an artificial sweetener, like Sweet ‘N Low, Equal or Splenda to drop into our coffee or iced tea. I mean, why not? Artificial sweeteners seem to offer the best of both worlds: they’re sweeter than sugar without raising blood sugar levels and without the calories! I love Splenda and have been known to add 2-3 packets into one cup of coffee!
So this begs the question: What exactly is this stuff? Is it safe?
The short answer is: well yes, sort of. There’s a lot of conflicting info out there about artificial sweeteners and what they do to the human body. Here’s the info that I found out on the “Big Three” (Sweet ‘N Low, Equal & Splenda). I’ll give my impressions at the end!
1. Sweet ‘N Low
While the brand name is “Sweet ‘N Low”, these little pink packets are actually filled with a substance called saccharin, first discovered in 1878. It is 100 times sweeter than regular table sugar (sucrose). Saccharin has been linked to bladder cancer in lab rats, so up until 2000, packets of Sweet N Low included a related warning. In 2000, this warning was removed from all packets after scientists discovered that it was the specific body chemistry of rats that (in combination with the saccharin) was causing the bladder cancer. You can check out the FDA regulations on saccharin here.
While the brand name is “Equal”, these little blue packets are actually filled with aspartame, dextrose and maltodextrin. Equal also used to be called “Nutrasweet”. It is 200 times sweeter than regular table sugar. When you digest aspartame, your body breaks it down into three different chemicals: aspartic acid, phenylalanine and methanol. These chemicals can be broken down further to create formaldehyde and formic acid.  Phenylalanine can be dangerous for people with a rare genetic disease called phenylketonuria because their bodies cannot properly metabolize it. Methanol is also a toxic chemical, but when produced in small quantities by the body is generally harmless. In 1996, after much controversy and debate, the Food & Drug Administration approved the use of aspartame in all foods. However, there is still much debate over whether aspartame is safe. This is specifically because studies have shown that there are health side effects associated with the consumption of aspartame. These include, but are not limited to, heart problems, hypertension, headaches, increased hunger and even depression. You can check out the FDA regulations on aspartame here.
While the brand name is Splenda, these little yellow packets contain sucralose, dextrose and maltodextrin. Splenda is 600 times sweeter than table sugar. Since sucralose is Splenda’s distinguishing feature, you should know that very little of the sucralose you ingest when eating Splenda is actually metabolized (unlike aspartame). This has made sucralose an increasingly more popular sweetener as compared to aspartame. Also setting sucralose apart from other sweeteners is the fact that you can cook with it; it can be heated and there’s also granulated Splenda products specifically made for baking/cooking. Splenda came under fire when a 2008 Duke study was released showing that when Splenda was ingested by lab rats -at amounts within FDA-guidelines- the rats showed (i) reduced gut bacteria (that’s the good bacteria needed to process foods) and (ii) weight gain . However, since these results have not been found in humans, there has been no change in the FDA’s outlook and Splenda is still deemed safe for human consumption. You can check out the FDA regulations on sucralose here.
A Quick Note on Dextrose & Maltodextrin
I want to briefly address dextrose & maltodextrin, since they’re used in both Equal and Splenda. Both of these ingredients are used as “bulking agents” in these sweeteners. Dextrose is actually just an isomer (same molecular chemistry but different molecular structure) of glucose. Maltodextrin is made up of a molecular chain of dextrose molecules, so it is effectively glucose as well . You can find maltodextrin in a lot of the sodas you drink and in other processed foods. Both dextrose and maltodextrin are easily metabolized by your body just as glucose is, so there’s no new health issues here. Because both of these ingredients are used in very small quantities in the production of Equal and Splenda, the sweeteners are still considered “calorie-free”. However, please note that this doesn’t mean that Equal and Splenda are “no carb”; since they contain glucose they have come carbs in them, just in very small quantities.
My Two Cents
In the process of researching for this post, I was shocked to learn that each of the three sweeteners I use on a regular, daily basis have been associated with health safety concerns! I suppose Splenda’s backstory is the least problematic, but the more I learn about these sweeteners, the more wary I become of using them on a regular basis. I’m going to try to cut back on my Splenda intake just to be on the safe side. What you choose to do with this information is entirely up to you, but I’d advise everyone to talk to their doctor if they have questions or concerns about their artificial sweetener intake.
Well! Perhaps natural sweeteners will offer “a new hope”? Check in next time for my final post: What Are Natural Sweeteners? (Part III of the Sugar Series) to find out!
