Unscramble the Blue Letters

Speaking of healthy foods, let's say you're hungry and decide to eat a balanced meal. You do, and dopamine levels spike in the reward system hot spots. But if you eat that same dish many days in a row, dopamine leelvs will spike less and less, eventually leveling out. That's because when it comes to food, the brain eeolvvd to pay special aeontttin to new or different tastes. Why? Two reasons: first, to detect food that's gone bad. And second, because the more vrteaiy we have in our diet, the more likely we are to get all the nrneiutts we need. To keep that variety up, we need to be able to rgzeicnoe a new food, and more iaomltrtnpy, we need to want to keep eating new foods. And that's why the dopamine levels off when a food becomes boring.

Original Text

Speaking of healthy foods, let's say you're hungry and decide to eat a balanced meal. You do, and dopamine levels spike in the reward system hot spots. But if you eat that same dish many days in a row, dopamine levels will spike less and less, eventually leveling out. That's because when it comes to food, the brain evolved to pay special attention to new or different tastes. Why? Two reasons: first, to detect food that's gone bad. And second, because the more variety we have in our diet, the more likely we are to get all the nutrients we need. To keep that variety up, we need to be able to recognize a new food, and more importantly, we need to want to keep eating new foods. And that's why the dopamine levels off when a food becomes boring.
