The Top 20 Most Addictive Foods, According to Study

We all have late-night cravings we're not proud of, but it's not entirely our fault; the most addictive foods seem to jack directly into the reward centers of our brains, some by direct design. Now a team of researchers from the University of Michigan have created a list of the most addictive foods. Unsurprisingly, pizza reigned supreme.

The two-part study, published in the journal PLOS ONE, involved surveying 120 undergraduate students in one experiment, and conducting a questionnaire among 384 participants in the other. Participants in the first study, all between the ages of 18 and 23, were first shown the Yale Food Addiction Scale (YFAS), a "measure that has been developed to identify those who are most likely to be exhibiting markers of substance dependence with the consumption of high fat/high sugar foods." The scale is based on standard criteria for substance dependence. 

The participants were then presented with food picture pairings and asked to choose which of the two they were "more likely to experience 'problems' with, as described by the YFAS." (Of the group, 75 percent were Caucasian, and about 68 percent were female.) Among the problems they could report were eating more of a food than they intended to, being unable to quit a food, giving up important activities, or showing an increased "tolerance" for a food.   

The research showed that of the 35 food options, those that have been processed and contain more fat and a higher glycemic load are most frequently associated with addictive-like eating behaviors. 

For the second study, instead of choosing between two food pictures, the participants, aged 18 to 64 (about 59 percent male and 77 percent Caucasian), were asked to rate each of the 35 foods on a Likert scale from one to seven, with seven being "extremely problematic."

"It is plausible that like drugs of abuse," reads the conclusion of the study, "these highly processed foods may be more likely to trigger addictive-like biological and behavioral responses due to their unnaturally high levels of reward."

The results varied slightly between the two parts of the study, but pizza, chocolate, cookies, and ice cream placed in the top five on both lists. Here are the items that made the Top 20 from the second study's ranking (which the researchers found to be a "more representative, diverse sample"), in order of most to least addictive: 

1. Pizza
2. Chocolate
3. Chips
4. Cookies
5. Ice Cream
6. French Fries
7. Cheeseburger
8. Non-Diet Soda
9. Cake
10. Cheese
11. Bacon
12. Fried Chicken
13. Rolls
14. Buttered Popcorn
15. Cereal
16. Gummies
17. Steak
18. Muffins
19. Nuts
20. Eggs

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

Here's How to Change Your Name on Facebook

Whether you want to change your legal name, adopt a new nickname, or simply reinvent your online persona, it's helpful to know the process of resetting your name on Facebook. The social media site isn't a fan of fake accounts, and as a result changing your name is a little more complicated than updating your profile picture or relationship status. Luckily, Daily Dot laid out the steps.

Start by going to the blue bar at the top of the page in desktop view and clicking the down arrow to the far right. From here, go to Settings. This should take you to the General Account Settings page. Find your name as it appears on your profile and click the Edit link to the right of it. Now, you can input your preferred first and last name, and if you’d like, your middle name.

The steps are similar in Facebook mobile. To find Settings, tap the More option in the bottom right corner. Go to Account Settings, then General, then hit your name to change it.

Whatever you type should adhere to Facebook's guidelines, which prohibit symbols, numbers, unusual capitalization, and honorifics like Mr., Ms., and Dr. Before landing on a name, make sure you’re ready to commit to it: Facebook won’t let you update it again for 60 days. If you aren’t happy with these restrictions, adding a secondary name or a name pronunciation might better suit your needs. You can do this by going to the Details About You heading under the About page of your profile.
