As the holiday season ushers in an abundance of sweet treats, many Americans are increasingly opting for sugar-free alternatives in an effort to reduce their sugar intake. This trend reflects a broader consumer shift, with a 2025 International Food Information Council survey indicating that 75 percent of Americans aim to limit or avoid sugar, and 22 percent specifically choose sugar-free options. The global sugar-free confectionery market is projected to nearly double from $42.5 billion in 2023 to $84.3 billion by 2032, according to Dataintelo, a market research firm.

Despite the growing popularity and perceived health benefits, dietitians and recent research suggest that these alternatives may not always be the healthier choice. Experts caution against the pervasive “fear-based messaging” surrounding natural sugar, emphasizing that sugar has a legitimate place within a balanced diet. However, the ingredients often used to replace sugar in these products are raising significant health concerns among medical professionals.

One of the most concerning findings links artificial sweetener consumption to cognitive decline. Researchers from the American Academy of Neurology recently reported that individuals consuming more than 190 milligrams of sweeteners daily over a year experienced a 62 percent faster decline in cognitive and memory skills compared to those consuming 20 milligrams. This study highlights potential long-term neurological impacts that extend beyond typical dietary concerns.

Registered Dietitian Avery Zenker of Ontario, Canada, points out that artificial sweeteners like sucralose, aspartame, and stevia, while reducing calories, can disrupt gut microbiome balance, increase inflammation, and even alter appetite, potentially leading to increased cravings for other foods. Such disruptions can make individuals more susceptible to infections and contribute to conditions like “leaky gut,” characterized by a damaged intestinal lining and symptoms such as bloating and food sensitivities. Some individuals also report headaches or general digestive discomfort from these additives.

Beyond artificial sweeteners, many sugar-free products contain sugar alcohols such as erythritol, xylitol, sorbitol, and maltitol. While these provide sweetness, they are not fully absorbed by the digestive tract. Alison Swiggard, a Registered Dietitian Nutritionist in Portland, Maine, explains that these compounds travel to the large intestine where bacteria ferment them, often resulting in increased gas production, bloating, cramping, and loose stools when consumed in substantial quantities.

Furthermore, to compensate for the loss of sugar, manufacturers often incorporate other ingredients that present their own health risks. Sugar-free desserts frequently rely on saturated fats like butter and palm oil to maintain flavor, moisture, and structure. Excessive intake of saturated fats is strongly linked to increased risks of cardiovascular disease and high cholesterol, with research indicating that replacing these fats with unsaturated alternatives significantly reduces mortality and cardiovascular events.

Many sugar-free options also contain significant amounts of refined carbohydrates, including wheat flour and various starches. Zenker warns that a high consumption of these refined carbohydrates can contribute to weight gain, systemic inflammation, and worsen insulin sensitivity, which is crucial for stable blood sugar levels. She notes that the glucose from such carbohydrates is rapidly absorbed, raising blood sugar and potentially increasing the risk of type 2 diabetes. Replacing added sugar with high-glycemic index refined carbohydrates in sugar-free desserts offers minimal benefit and may exacerbate certain health risk markers.

Despite these concerns, artificial sweeteners can offer specific benefits for certain individuals. The Mayo Clinic notes their role in reducing the risk of tooth decay and cavities. For some, they serve as a short-term tool for weight management or are consumed for medical reasons, such as diabetes. However, both Swiggard and Zenker stress the importance of reading ingredient labels carefully and reflecting on the underlying reasons for choosing these foods.

Swiggard advises that if sugar-free options genuinely provide satisfaction and support, they can be part of holiday eating. Conversely, if they feel restrictive or unsatisfying, enjoying traditional desserts in moderation might be more nourishing both physically and emotionally. For those seeking alternatives without added sugars or artificial sweeteners, Zenker suggests embracing whole-food sweeteners like dates, bananas, and applesauce. These natural options, while containing sugar, are nutrient-dense and not as strongly linked to the health risks associated with refined sugars.
