Summary
858. Are "low net carb" candies actually a healthy alternative, or just clever chemistry? In this episode, Monica breaks down the science of net carbs and the marketing behind some brands.
We dive deep into the ingredient list to explain how sugar alcohols (like erythritol and isomalt) and functional fibers (like polydextrose and soluble corn fiber) affect your body. If you’ve ever wondered why low-sugar treats cause bloating or gas, or if those 26 grams of fiber actually "count," this episode is for you.
In this episode, we discuss:
- How to calculate net carbs: The math manufacturers use to subtract fiber and sugar alcohols from total carbohydrates.
- The GI Impact: Why high-fiber candies can lead to digestive discomfort and "functional fiber" warnings.
- Blood Sugar vs. Calories: How keto-friendly sweets compare to traditional treats like Swedish Fish.
- Food Psychology: Why labeling food as "Shameless" or "Guilt-Free" can harm our relationship with eating.
Stop viewing your snack choices as a moral scorecard. Listen to learn how to read nutrition facts labels with a critical eye and choose the treats that actually make your body feel good.

| 0:00.0 | A listener recently asked me about a new brand of candy that claims to have almost no net carbs, |
| 0:07.2 | even though it's not technically low in carbohydrates. |
| 0:10.8 | So today I want to talk about how exactly they calculate net carbs, |
| 0:15.5 | a bit about the ingredients that they use to pull off this particular magic trick, |
| 0:19.9 | and whether they actually are |
| 0:21.9 | as harmless as they seem. |
| 0:30.3 | Hello, I'm Monica Reinagle, and you are listening to the Nutrition Diva podcast, a show where we take |
| 0:35.6 | a closer look at nutrition news, research, and |
| 0:38.1 | trends, and answer your food and nutrition questions. And today's episode was inspired by an |
| 0:44.1 | email from Linda, who recently wrote to ask about a brand of gummy candies called |
| 0:49.8 | Shameless. These products are being promoted as low-net carb with less sugar and fewer calories |
| 0:57.4 | than traditional gummy candies, and Linda wanted to know, are they actually a better option? |
| 1:04.9 | Now, being someone with a real soft spot for Swedish fish, this one hit close to home. But more importantly, it's a good |
| 1:14.1 | opportunity to review with you what this whole net carb concept is all about, as well as to share |
| 1:20.2 | a few thoughts about what it says about us that candies are marketed to us in terms of how much |
| 1:26.0 | shame we should feel about eating them. Okay, but let's start |
| 1:31.0 | with what's in these candies. Because given that this brand markets itself as having zero junk, |
| 1:38.7 | the ingredient list might raise a few eyebrows. Most of the sweetness in these candies comes from sugar alcohols, |
| 1:47.0 | specifically erythritol and isomalt, along with a small amount of sucralose, also known as |
| 1:54.2 | Splenda. Sugar alcohols, sometimes referred to as polyols, are carbohydrates, and they are reflected in the total |
| 2:03.9 | carbohydrate count on the nutrition facts labels. But because of their molecular structure, |
| 2:09.2 | they are not fully absorbed and metabolized like regular sugar. As a result, they provide |
