For some people,(22)getting hooked on super-tasty food—sugary soda and ice cream, salty French fries and pizza—might be partly responsible for their craving, binge eating and weight gain. High levels of sugar, fat and salt, and various flavors and food additives might actually hijack the pathways of the brain in ways that are similar to pain-killers and other drugs.(23)The evidence suggests that sugar in particular stimulates a greater release of chemicals in the brain—including dopamine, the "pleasure molecule"—than releases triggered by, say, fruit and vegetables. Over time, the brain’s circuitry might become rewired to produce less dopamine in response to high-calorie, flavor-enhanced foods.(24)As a result—and possibly in combination with genetics and environmental factors—some people will eat more, attempting to stimulate dopamine production to feel good. That’s similar to what often happens when a person is addicted to alcohol, nicotine or narcotics. Conceptually, it’s pretty clear that highly delicious foods can have drug-like effects in the brain and can cause compulsive overuse and food addiction. Experimental results seem to suggest that people who find food more exciting are more likely to overeat and gain weight. And the more you eat high-fat or high-sugar foods, the less your brain regions are activated by actual intake of these foods. But not everyone is swallowing the theory.(25)Food addiction hasn’t been formally recognized by the American Psychiatric Association. And there’s a lack of objective evidence that the condition contributes greatly to the obesity epidemic in America.
22. What consequence may super-tasty food lead to for some people?
23. What is dopamine according to the speaker?
24. What can we know about super-tasty food?
25. Why is not everyone swallowing the food addition theory?
