The Neuroscience of Sweet and Fatty Foods: How They Affect Our Brain Preferences.

Consuming high-fat and high-sugar foods causes changes in activity and connectivity in the brain’s dopaminergic system, resulting in a stronger preference for these foods. Researchers at the Max Planck Institute for Metabolism Research in Cologne, in collaboration with Yale University, have shown that the brain unconsciously learns to prefer high-fat and high-sugar foods, leading to a preference for these foods in the future. The study found that the brain rewires itself through the consumption of high-fat and high-sugar foods, subconsciously learning to prefer rewarding food, even after the study period.
