Conclusion: “High-sugar intake stimulates the reward center in the brain, releasing dopamine, which produces a feeling of pleasure similar to the physiological mechanisms of drug addiction. Long-term consumption of high-sugar-containing foods increases sugar cravings, withdrawal symptoms, mood swings, and psychological dependence on sugar. Sugar addiction leads to obesity, diabetes, cardiovascular disease, and other health problems that are harmful to the physical health of individuals.”
