Preference for Sweets, Dopamine Receptors and Obesity (AUDIO)
Caption
As we get older, we tend to have less of a preference for sweet things. during that same time in life, the number of a particular type of dopamine receptor in our brains begins to decline, and there is a strong relationship between receptors, age and sweet taste preferences in people who don't have obesity. but scientists at Washington University School of Medicine in St. Louis have found that things don't work that way in people who do have obesity. Jim Dryden has the story.
