How Your Cup's Color Changes the Taste of Your Drink

By Jessica Hullinger

In the mood for a cup of hot chocolate? Do yourself a favor: Drink it from an orange cup.

New research from the Journal of Sensory Studies says different colored cups can affect the perceived flavor of beverages. "The color of the container where food and drink are served can enhance some attributes like taste and aroma," said study co-author Betina Piqueras-Fiszman, a researcher at the Universitat Politècnica de València in Spain and the University of Oxford in the United Kingdom.

Piqueras-Fiszman and her colleagues asked 57 people to sip four samples of the same hot chocolate from different colored cups: White, cream, orange, and red. At the end of the experiment, all 57 participants said the hot chocolate in the orange and cream cups tasted better, with some reporting it was sweeter or smelled more aromatic.

What causes this perceived flavor enhancement? It's all in our heads. Presumably, orange and cream bring to mind warm, creamy flavors in a way that white and red do not. In the past, similar studies have shown that factors unrelated to taste, such as price and verbal descriptions of food, can affect how flavor is perceived. As Jesus Diaz at Gizmodo notes, soda is considered more refreshing when served in a blue can (perceived as colder than a warm red can), and coffee tastes stronger when in a brown package, tips manufacturers already use to their advantage. "The discovery demonstrates once again that our taste buds are definitely influenced by the colors our eyes perceive," Diaz says.

The findings shed light on new techniques restaurants could use to enhance patrons' dining experience. "More attention should be paid to the color of the container as it has more potential than one could imagine," says Piqueras-Fiszman. So next time you're out to dinner and order a hot chocolate, be sure to ask for it in an orange mug.

Feeling Down? Lifting Weights Can Lift Your Mood, Too

There’s plenty of research that suggests that exercise can be an effective treatment for depression. In some cases of depression, in fact—particularly less-severe ones—scientists have found that exercise can be as effective as antidepressants, which don’t work for everyone and can come with some annoying side effects. Previous studies have largely concentrated on aerobic exercise, like running, but new research shows that weight lifting can be a useful depression treatment, too.

The study in JAMA Psychiatry, led by sports scientists at the University of Limerick in Ireland, examined the results of 33 previous clinical trials that analyzed a total of 1877 participants. It found that resistance training—lifting weights, using resistance bands, doing push ups, and any other exercises targeted at strengthening muscles rather than increasing heart rate—significantly reduced symptoms of depression.

This held true regardless of how healthy people were overall, how much of the exercises they were assigned to do, or how much stronger they got as a result. While the effect wasn’t as strong in blinded trials—where the assessors don’t know who is in the control group and who isn’t, as is the case in higher-quality studies—it was still notable. According to first author Brett Gordon, these trials showed a medium effect, while others showed a large effect, but both were statistically significant.

The studies in the paper all looked at the effects of these training regimes on people with mild to moderate depression, and the results might not translate to people with severe depression. Unfortunately, many of the studies analyzed didn’t include information on whether or not the patients were taking antidepressants, so the researchers weren’t able to determine what role medications might play in this. However, Gordon tells Mental Floss in an email that “the available evidence supports that [resistance training] may be an effective alternative and/or adjuvant therapy for depressive symptoms that could be prescribed on its own and/or in conjunction with other depression treatments,” like therapy or medication.

There haven’t been a lot of studies yet comparing whether aerobic exercise or resistance training might be better at alleviating depressive symptoms, and future research might tackle that question. Even if one does turn out to be better than the other, though, it seems that just getting to the gym can make a big difference.

Uncombable Hair Syndrome Is a Real—and Very Rare—Genetic Condition

Everyone has bad hair days from time to time, but for roughly 100 people around the world, unmanageable hair is an actual medical condition.

Uncombable hair syndrome, also known as spun glass hair syndrome, is a rare condition caused by a genetic mutation that affects the formation and shape of hair shafts, BuzzFeed reports. People with the condition tend to have dry, unruly hair that can't be combed flat. It grows slower than normal and is typically silver, blond, or straw-colored. For some people, the symptoms disappear with age.

Although there have been only about 100 documented cases worldwide, one of the world's leading researchers on the condition, Regina Betz, of Germany's University of Bonn, believes there could be thousands of others who have it but have not been diagnosed. Some have speculated that Einstein had the condition, but without a genetic test, it's impossible to know for sure.

An 18-month-old American girl named Taylor McGowan is one of the few people with this syndrome. Her parents sent blood samples to Betz to see if they were carriers of the gene mutation, and the results came back positive for variations of PADI3, one of three genes responsible for the syndrome. According to IFL Science, the condition is recessive, meaning that it "only presents when individuals receive mutant gene copies from both parents." Hence it's so uncommon.

Taylor's parents have embraced their daughter's unique 'do, creating a Facebook page called Baby Einstein 2.0 to share Taylor's story and educate others about the condition.

"It's what makes her look ever so special, just like Albert Einstein," Taylor's mom, Cara, says in a video uploaded to YouTube by SWNS TV. "We wanted to share her story with the world in hopes of spreading awareness."
