Added sugar can have terrible effects on your metabolism and overall health.
For this reason, many people turn to artificial sweeteners like sucralose (Splenda).
However, while authorities claim that sucralose is safe to eat, some studies have linked it to health problems.
This article takes an objective look at sucralose and its health effects, both good and bad.
I. What is Sucralose/Splenda?
Sucralose is a zero-calorie artificial sweetener, and Splenda is the most common sucralose-based product.
Sucralose is made from sugar, in a multi-step chemical process where 3 hydrogen-oxygen groups are replaced with chlorine atoms.
It was discovered in 1976, when a scientist at a British college misheard instructions about testing a substance. Instead, he tasted it, realizing that it was highly sweet.
Splenda products were then jointly developed by the companies Tate & Lyle and Johnson & Johnson. It was introduced in the US in 1999, and is one of the most popular sweeteners in the country.
Splenda is commonly used as a sugar substitute in both cooking and baking. It’s also added to thousands of food products worldwide.
However, the total calories and carbs contributed by Splenda are negligible because you only need to use tiny amounts each time.
Bottom Line: Sucralose is an artificial sweetener, and the most popular product made from it is called Splenda. Sucralose is made from sugar, but contains no calories and is much sweeter.
II. Sucralose May Affect Blood Sugar and Insulin
Sucralose is said to have little or no effects on blood sugar and insulin levels.
However, this may depend on you as an individual and whether you’re used to consuming artificial sweeteners.
So, if you don’t consume sucralose on a regular basis, it’s possible that you may experience some changes to your blood sugar and insulin levels.
If you’re used to consuming sucralose, then it probably won’t have any effect.
Bottom Line: Sucralose may raise blood sugar and insulin levels in people who do not consume artificial sweeteners regularly. However, it probably has no effect in people who regularly use artificial sweeteners.
III. Baking with Sucralose May Be Harmful
Splenda is considered to be heat-resistant, and good for cooking and baking. Yet recent studies have challenged this.
It seems that at high temperatures, it starts to break down and interact with other ingredients (8).
Bottom Line: At high temperatures, sucralose may break down and generate harmful substances.
IV. Does Sucralose Affect Gut Health?
The friendly bacteria in the gut are extremely important for your overall health.
Interestingly, one rat study found that sucralose may have negative effects on these bacteria.
What’s more, the gut bacteria had still not returned to normal 12 weeks after the experiment was finished.
Nevertheless, this was a study of rats. Human studies are needed to explore whether the gut bacteria really are affected.
Bottom Line: Animal studies link sucralose to negative effects on the bacterial environment in the gut. However, human studies are needed.
V. Does Sucralose Make You Gain or Lose Weight?
Products that contain zero-calorie sweeteners are often marketed as being good for weight loss.
However, sucralose and artificial sweeteners don’t seem to have any major effects on your weight.
Observational studies find no connection between artificial sweetener consumption and body weight or fat mass, but some of them report a small increase in body mass index (15).
A review of randomized controlled trials, the gold standard of research, reports that artificial sweeteners reduce body weight by around 1.7 lbs (0.8 kg) on average (15).
Bottom Line: Sucralose and other artificial sweeteners do not seem to have any major effects on body weight.
V!. Is Sucralose Safe?
Like other artificial sweeteners, sucralose is highly controversial. Some claim that it is totally harmless, but new studies suggest that it may have some effects on your metabolism.
For some people, it may raise blood sugar and insulin levels. It may also damage the bacterial environment in the gut, but this needs to be studied in humans.
The safety of sucralose at high temperatures has also been questioned. You may want to avoid cooking or baking with it, as it may release harmful compounds.
That being said, the long-term health effects are still not clear, and health authorities like the FDA do consider it to be safe.
Bottom Line: Health authorities consider sucralose to be safe, but studies have raised questions about its health effects. The long term health effects of consuming it are unclear.
V!I. Should You Avoid it?
If you like the taste of sucralose and your body handles it well, then it’s probably fine to use. There is certainly no clear-cut evidence that it is harmful, at least not in humans.
However, it may be a bad choice for high-heat cooking and baking, and it may be something to look at if you have persistent problems related to gut health.
If you choose to avoid sucralose or artificial sweeteners in general, then there are plenty of great alternatives.
