Sugar Is the World’s #3 Calorie Source And It’s Slowly Killing Us.

Globally, added sugar now makes up around 10% of total calories consumed, ranking just behind grains and produce. But while those provide some nourishment, sugar contributes little and harms much. A 2023 Annual Review study warns that sugar—not fat—is driving the chronic disease epidemic. And sugar-sweetened beverages (SSBs) are the worst offenders.

Multiple studies show strong links between high sugar consumption and obesity, type 2 diabetes, cardiovascular disease, non-alcoholic fatty liver disease, kidney stones, and depression. One study found that getting 17–21% of your calories from added sugar raises your risk of dying from heart disease by 38%. Another showed that regular consumption of sugary drinks is associated with increased risks of depression and cancer.

Biologically, sugar disrupts nearly every system it touches. Glucose spikes increase advanced glycation end products (AGEs), which damage cells, age tissues, and promote oxidative stress. This isn’t just about weight—sugar accelerates aging from the inside out.

Avoid added sugars—especially sugary drinks. Focus on whole foods, and if you crave something sweet, stick to fruit or raw honey.
