In recent years, growing evidence suggests that refined sugar may have addictive properties, impacting both our brains and bodies in profound ways. Scientists and health professionals increasingly recognize that even small but consistent amounts of sugar can negatively affect our physical and mental health. Diets high in carbohydrates and added sugars may trigger changes in brain chemistry and behavior, resembling addiction.
Sugar and the Brain
According to Nicole Avena, a neuroscientist at Columbia University, consuming excessive carbohydrates—which convert to sugar—can lead to behaviors similar to addiction. “About 11 percent of the population meets the criteria for food addiction,” Avena states, “and most say they’re hooked on carbohydrates.”
While more research is needed, early findings suggest that sugar consumption can cause changes in brain pathways, leading to cravings and overconsumption. Ashley Gearhardt, a psychologist at the University of Michigan, explains, “The addiction jury is still out on sugar. We need to better understand whether people addicted to sugar experience tolerance and withdrawal in the same way as drug users.”
The Broader Health Impact
The implications of sugar addiction extend beyond the brain. Robert Lustig, a pediatric endocrinologist at the University of California, San Francisco, found a correlation between sugar availability and diabetes rates across 175 countries. While sugar may not directly cause diabetes, Lustig’s research highlights a potential relationship between high sugar consumption and disease prevalence.
Similarly, studies at the Mayo Clinic reveal that diets heavy in sugar may increase the risk of cognitive impairment in older adults. Dr. Roberts from the Mayo Clinic notes, “High levels of sugar may actually prevent the brain from effectively using sugar—similar to what we see with type 2 diabetes.” In contrast, diets high in protein and healthy fats relative to carbohydrates appear to lower the risk of cognitive decline.
A Call for Change
On average, Americans consume 22 teaspoons of sugar daily—far exceeding recommended limits. Understanding the negative effects of excessive sugar can empower individuals to make healthier choices. Cutting out obvious sources of sugar is a crucial first step toward better health. By adopting balanced diets rich in protein, healthy fats, and natural sugars from whole foods, we can improve our overall well-being.
