Recently, a study by Yale University School of Medicine proved that junk food with high sugar and oil can really bring happiness to the brain. It is found that the human brain has different reward circuits for sugar and lipid, and foods with high oil and sugar may trigger two mechanisms, namely, the super-additive effect of .5+.5 > 1.

A long time ago, in the hunting and gathering era, human beings rarely had the opportunity to eat sugar and lipid together. A meal was mainly fruit or meat. Over time, the human brain evolved two different reaction mechanisms: one was suitable for sugar and the other was suitable for lipid. Therefore, when someone accidentally ate sugar and lipid together, the two reward circuits worked together in the brain, and finally they enjoyed it better than eating either one alone.
