The science (and sales appeal) of low net carb candies

In this episode of Nutrition Diva, Monica Reinagle investigates the science and marketing behind low-net-carb candies, specifically a brand called Shameless gummies. She explains how manufacturers calculate 'net carbs' by subtracting fiber and sugar alcohols from total carbohydrates—a practice that, while not officially regulated, reflects the reduced blood sugar impact of these ingredients. The candies use erythritol, isomalt, sucralose, and functional fibers like polydextrose and soluble corn fiber to achieve a low glycemic profile and fewer calories compared to traditional gummies. However, Monica cautions that the high fiber and sugar alcohol content can cause digestive discomfort, especially in sensitive individuals. She critiques the brand's 'shameless' positioning, arguing that moralizing food—labeling some as 'guilt-free' or 'shameless'—perpetuates unhealthy relationships with eating and self-worth. Instead, she advocates for a neutral, evidence-based approach to food choices, emphasizing personal preference, digestive tolerance, and overall dietary patterns over moral judgments.
