Your brain on carbohydrates and fat? It's in love
Pizza? Doughnuts? They satisfy the brain's reward center like nothing else.
Then, they were asked to estimate how many calories and how much they'd pay for it.
"Surprisingly, foods containing fats and carbohydrates appear to signal their potential caloric loads to the brain via distinct mechanisms. Our participants were very accurate at estimating calories from fat and very poor at estimating calories from carbohydrate," explained Dana Small, director of the Modern Diet and Physiology Research Center at Yale University.
The kicker? People would also pay more money for the foods containing both fat and carbs. Oh, and it's very hard to stop eating them once you start.
The key is in the reward center of the brain; these foods can light that right up, and release dopamine, the hormone that says, "Wow. I love this."
With further study, it's possible for scientists to figure out how to turn off that reward center, at least to a certain extent; as it is now, eating those foods tends to hit the reward center of the brain so much that it's very hard for us to stop eating when we start. It's not the same as other foods—in fact, it's not all that recent that these foods were created, so they calculate that the brain doesn't really know how to handle them. Before those foods were invented, humans didn't have these kinds of options nearly as much as we do today.
The study also discovered that the brain can handle either carbs or fat, but not both at the same time; when presented with such an option, it doesn't know quite how to respond.
So... bring on the donuts?

A consortium of scientists and engineers have proposed that the U.S. and Mexico build a series of guarded solar, wind, natural gas and desalination facilities along the entirety of the border.
- The proposal was recently presented to several U.S. members of Congress.
- The plan still calls for border security, considering all of the facilities along the border would be guarded and connected by physical barriers.
- It's undoubtedly an expensive and complicated proposal, but the team argues that border regions are ideal spots for wind and solar energy, and that they could use the jobs and fresh water the energy park would create.
Yes, a coup d'état.
- Though we know today that his policies eventually ended the Great Depression, FDR's election was seen as disastrous by some.
- A group of wealthy bankers decided to take things into their own hands; they plotted a coup against FDR, hoping to install a fascist dictator in its stead.
