The teenage brain explained or the reason why young skulls are full of mush.

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine — an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.

No matter how much calorie information is presented to the consumer, people still choose the food they like, not what’s supposed to be healthier for them.
When calorie counts are posted for various foods, be aware that your mileage may vary. Sometimes it’s due to a generous server and just a dollop more than the standard size. And the fact that a Subway sandwich comes in as fewer than the stated calories can be attributed to the fact that Subway footlongs are eleven inches. But some foods have calorie counts that don’t seem to be related to reality at all.
If foods are going to have mandated calorie labels, why aren’t they mandated to be accurate? Because testing and enforcement is time-consuming and expensive, as you’ll see in this video by Casey Neistat of the New York Times. -via Nag on the Lake
