Why Do We Crave Chocolate?

If you’re like most people, you simply can’t pass up the opportunity to partake in a piece of chocolate (or five). Some have even said that chocolate melting on the tongue is better than a kiss. But why do we love chocolate so much?

Our cravings can be traced to two places: Our guts—studies have shown that chocolate lovers have different bacteria in their intestines than non-chocolate lovers—and our brains. We crave chocolate because eating it results in the production of opioids, which dull pain and increase levels of dopamine, a neurotransmitter in the brain’s reward system that helps us experience pleasure. (Drugs like cocaine and amphetamines work directly on the dopamine system.)

Chocolate can have many health benefits in moderation, but often, people can’t stop popping truffles—and scientists might know why. In a recent study, researchers working with rats injected a drug directly into the neostriatum, a region of the brain primarily associated with movement. When the rats began to eat M&Ms, a naturally occurring chemical produced in that region of the brain, called enkephalin, surged, increasing the rats’ desire to eat the candies. The animals ate twice the number of M&Ms they would have eaten normally.

Alexandra DiFeliceantonio, a researcher at the University of Michigan, Ann Arbor who ran the study, says this same area is active when obese people see food, or when drug users take in a drug scene. “This means that the brain has more extensive systems to make individuals want to overconsume rewards than previously thought,” she said. "It seems likely that our enkephalin findings in rats mean that this neurotransmitter may drive some forms of overconsumption and addiction in people."

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

More Than 38,000 Pounds of Ground Beef Has Been Recalled

Your lettuce-based summer salads are safe for the moment, but there are other products you should be careful about using these days: Certain brands of hand sanitizer, for example, have been recalled for containing methanol. And as Real Simple reports, the U.S. Department of Agriculture’s Food Safety Inspection Service (FSIS) recently recalled 38,406 pounds of ground beef.

When JBS Food Canada ULC shipped the beef over the border from its plant in Alberta, Canada, it somehow skirted the import reinspection process, so FSIS never verified that it met U.S. food safety standards. In other words, we don’t know if there’s anything wrong with it—and no reports of illness have been tied to it so far—but eating unapproved beef is simply not worth the risk.

The beef entered the country on July 13 as raw, frozen, boneless head meat products, and Balter Meat Company processed it into 80-pound boxes of ground beef. It was sent to holding locations in Florida, Georgia, North Carolina, and South Carolina before heading to retailers that may not be specific to those four states. According to a press release, FSIS will post the list of retailers on its website after it confirms them.

In the meantime, it’s up to consumers to toss any ground beef with labels that match those here [PDF]. Keep an eye out for lot codes 2020A and 2030A, establishment number 11126, and use-or-freeze-by dates August 9 and August 10.
