Is This the End of Erythritol?
What This Study Means for Low-Carb Recipes

The First Erythritol Study: A Recap of Previous Concerns

So, before we dive into the  new study from August 2024, let’s quickly revisit what had us all talking in the first place. Last time, we discussed how  this study from 2023 showed a possible link between high erythritol levels and an increased risk of cardiovascular events—think heart attacks and strokes. The idea was that erythritol might make your platelets (those tiny blood cells that help clots form) more “sticky,” potentially increasing the risk of clots.

I know, it sounded a bit alarming. But at that point, I urged caution instead of panic. After all, while the findings were concerning, the real-world implications weren’t totally clear. Was erythritol really the cause? Or could it be that people with higher cardiovascular risks were just more likely to consume it? That’s where the debate really began.

The New Erythritol Study: What’s New?

Now, here’s where things get interesting.  The new study looked at what happens when people consume erythritol versus glucose. They took 20 healthy volunteers and gave them either 30 grams of erythritol (yep, that same amount you might find in some of your favorite keto treats, or at least the sweeter ones) or glucose, then measured how their platelets responded.

The results? Erythritol led to significantly higher platelet activity, which means it could increase the risk of blood clots. Glucose didn’t have the same effect, making erythritol the one under the spotlight here.

What does that mean for you and me? Well, it suggests that erythritol could affect how our blood clots, especially if we consume it in larger amounts. It’s a bit of a red flag, but as always, there’s more to the story.

Breaking Down the Methods

Let’s take a quick peek at how the researchers figured all of this out. They didn’t just make assumptions—they got into the nitty-gritty. The study involved 20 healthy volunteers, split into two groups: one drank a solution with 30 grams of erythritol, and the other had glucose. Then, the researchers measured platelet reactivity before and after.

This point is important because  unlike the previous study, which primarily examined participants with cardiovascular conditions, this study focused on healthy individuals. The earlier research raised some questions about whether pre-existing health issues could have influenced the results. This new study provided clarity by showing that even in healthy people, erythritol could lead to an increased risk of clot formation.

What did they find? Erythritol led to a big spike in platelet activity, meaning those platelets were more likely to form clots. The results were pretty consistent across participants.

But here’s an important note: the study only looked at what happened over a short period of time, just 30 minutes after consumption. So, while it’s telling us something about immediate effects, we don’t yet know how erythritol might affect us in the long run.

Study Limitations: What’s Missing?

As with any study, there are a few limitations worth noting—some mentioned by the researchers, and others that become clear when we dig deeper.

1. Highly Controlled Consumption

In this study, participants fasted overnight and consumed either erythritol or glucose on an empty stomach. This doesn’t exactly mirror how we typically consume sweeteners in real life. Most of us include erythritol in foods or drinks that also contain fat, protein, or fiber—nutrients that can slow down the absorption process. Consuming erythritol in isolation gives us limited insight into how it affects our bodies when it's part of a balanced meal.

2. Single Blood Test Timing

The study measured the participants’ blood levels only once, 30 minutes after consumption. This doesn’t give us the full picture. Blood sugar levels, for example, fluctuate at different times after eating, so it’s likely erythritol levels would too. Testing at additional intervals—like 1 or 2 hours post-consumption—would have provided more comprehensive data about how erythritol behaves in the bloodstream over time, similar to what they did in the previous study in 2023.

3. Short-Term Focus

The focus was on immediate, short-term effects, which are useful but don’t tell us much about what happens over longer periods. We still don’t know how moderate, repeated erythritol consumption affects the body after days, weeks, or even months. This makes it difficult to draw conclusions about its safety for regular, long-term use.

4. Relatively Small Sample Size

The study only involved 20 participants, which is a relatively small group. While the results were consistent, a larger sample size would give us more confidence in the findings and allow for a broader range of health conditions and lifestyles to be factored in.

5. Is 30 Grams of Erythritol a Lot?

It depends. Some critics of this study argue that 30 grams of erythritol is too much—but is it? The amount consumed in the study—30 grams—may seem high to some, but for those who regularly consume erythritol, it’s not that uncommon.

From my experience creating low-carb recipes, certain keto treats can contain close to this amount. For example, a chocolate mug cake with frosting could easily have 30 grams of sweetener if you eat the whole thing. Of course, not everyone would eat that much, especially after getting used to low-carb eating, when sweet cravings tend to fade.

And it’s not just homemade recipes. Ready-made products like bars and drinks often contain significant amounts of sweeteners, and the total can quickly add up. So, while 30 grams might sound like a lot, for regular consumers of keto desserts or sweetened snacks, it’s not entirely unrealistic.

Bottom line: These limitations don’t erase the findings, but they remind us that there’s still a lot more to understand about erythritol’s role in our diets—especially in real-world settings.

Who Should Be Concerned About Erythritol?

Now, this is where things get personal. Should you be worried about erythritol based on this study? Well, I’m not here to give you definitive answers—after all, that’s not my place, and it’s a decision that’s deeply personal, depending on your own health situation.

The study does raise concerns, particularly for people who already have health conditions that make them more prone to blood clots or cardiovascular issues. If you have a history of heart disease, diabetes, or clotting disorders, it might be worth paying closer attention to your erythritol intake. It’s also something to consider for those at higher risk of cardiovascular events due to age or other factors.

My Approach: A Balanced Perspective

As for myself, with  Factor V Leiden (a genetic condition that increases my risk of blood clots), this puts me in one of the groups who might need to be more careful. During my pregnancy and a few months postpartum, I was on blood thinners to manage this risk. While I haven’t noticed any adverse effects from my erythritol use, it’s something I’ve kept in mind ever since the initial study came out in 2023.

Since then, I’ve cut back on my erythritol consumption—not eliminating it completely, but balancing it with other sweeteners like allulose, monk fruit, or stevia extract. And just to be clear, I never consume erythritol in large quantities anyway—certainly not the 30 grams they tested in the study. But I do use it moderately in recipes, and I’m comfortable with that for now. Just to give you an idea, I still have the same bag of erythritol from 2023 when the last study came out.

Ultimately, we each need to weigh the potential risks and decide what feels right. For some, cutting back might be the best choice; for others, occasional use in moderation could be just fine. It's all about understanding the science and making choices that suit your own health and lifestyle. As I mentioned before, erythritol isn’t essential for me. Since the initial study came out, I’ve almost completely switched to allulose. My go-to brand is RxSugar, which I’ve trusted and used for years.

The Role of Erythritol in Recipes: Is it Easy to Replace?

For those of us who enjoy low-carb or keto baking, erythritol is more than just a sweetener—it’s a crucial ingredient in achieving the right texture and taste in many recipes. Unlike some other sugar substitutes, erythritol brings a unique combination of properties that make it particularly valuable in baking and desserts.

1. Sweetness with Bulk

Erythritol is about 60-70% as sweet as sugar, and unlike concentrated sweeteners like stevia or monk fruit, it adds bulk to recipes. This is especially important in baked goods where texture matters, like cookies, cakes, or muffins. Allulose and xylitol also provide sweetness with bulk.

2. No Bitter Aftertaste

One of erythritol’s biggest selling points is that it has little to no aftertaste, unlike some sweeteners that can leave a lingering bitterness. This makes it a popular choice in desserts where flavor is key. However, it does have a cooling effect, which some people notice as an aftertaste, though most don’t mind it.

3. Crucial for Crunch

In recipes like Keto Shortbread Cookies or crunchy biscuits, erythritol is what provides that crisp texture we all love. If you swap it for something like allulose, you’ll end up with a chewier result, which may or may not be what you’re looking for. There is no alternative to Erythritol that would help you achieve the same crunchy results. If you use allulose or xylitol, you will end up with softer, chewier cookies.

4. Less Expensive

While allulose is gaining popularity for its similar properties, it’s still more expensive than erythritol or xylitol. If you're using sweeteners regularly in your recipes, erythritol is generally a more budget-friendly option, making it accessible for everyday use.

5. Widely Available

Another big advantage of erythritol (and also xylitol) is that it’s widely available in most countries, whereas allulose is still relatively new and not yet sold everywhere. If you live outside the U.S., you may find it harder to get your hands on allulose, whereas erythritol can usually be found in most supermarkets and online. That said, Allulose was recently approved in Australia, which is great news for its growing availability.

6. Almost Zero Calories

Compared to xylitol, which is also commonly available, erythritol has the benefit of being almost calorie-free (just like allulose). It contains about 0.2 calories per gram, whereas xylitol contains 2.4 calories per gram—much closer to regular sugar. Also, while xylitol is toxic to dogs, erythritol is considered safe for pets, which is something to keep in mind if you have furry friends at home.

In short, while erythritol plays an important role in low-carb recipes, it’s not irreplaceable. Depending on what you're baking or cooking, you can experiment with substitutes that suit your needs while balancing any health concerns you may have. Just be mindful of how different sweeteners affect the final outcome in terms of sweetness, texture, and availability.

Conclusion

Erythritol remains a popular choice for many following a low-carb or keto lifestyle, but the recent studies have raised some important questions, especially for those with specific health concerns. While the research has limitations, staying informed and making thoughtful choices is key. Whether you continue using erythritol or explore alternatives like allulose, monk fruit, or stevia, the best approach is to choose what works for your health and personal preferences.
