Why (almost) everything you know about food is wrong

There was a time, in the distant past, when studying nutrition was a relatively simple science.

In 1747, a Scottish doctor named James Lind wanted to figure out why so many sailors got scurvy, a disease that leaves sufferers exhausted and anemic, with bloody gums and missing teeth. So Lind took 12 scurvy patients and ran the first modern clinical trial.

The sailors were divided into six groups, each given a different treatment. The men who ate oranges and lemons eventually recovered — a striking result that pointed to vitamin C deficiency as the culprit.

This sort of nutritional puzzle solving was common in the pre-industrial era. Many of troubling diseases of the day, such as scurvy, pellagra, anemia, and goiter, were due to some sort of deficiency in the diet. Doctors could develop hypotheses and run experiments until they figured out what was missing in people’s foods. Puzzle solved.

Unfortunately, studying nutrition is no longer that simple. By the 20th century, medicine had mostly fixed scurvy and goiter and other diseases of deficiency. In developed countries, these scourges are no longer an issue for most people.

Today, our greatest health problems relate to overeating. People are consuming too many calories and too much low-quality food, bringing on chronic diseases like cancer, obesity, diabetes, and heart disease.

The Akrasia Effect: Why We Don’t Follow Through on What We Set Out to Do (And What to Do About It)

By the summer of 1830, Victor Hugo was facing an impossible deadline. Twelve months earlier, the famous French author had made an agreement with his publisher that he would write a new book titled, The Hunchback of Notre Dame.

Instead of writing the book, Hugo spent the next year pursuing other projects, entertaining guests, and delaying his work on the text. Hugo’s publisher had become frustrated by his repeated procrastination and responded by setting a formidable deadline. The publisher demanded that Hugo finish the book by February of 1831—less than 6 months away.

Hugo developed a plan to beat his procrastination. He collected all of his clothes, removed them from his chambers, and locked them away. He was left with nothing to wear except a large shawl. Lacking any suitable clothing to go outdoors, Hugo was no longer tempted to leave the house and get distracted. Staying inside and writing was his only option. 

The strategy worked. Hugo remained in his study each day and wrote furiously during the fall and winter of 1830. The Hunchback of Notre Dame was published two weeks early on January 14, 1831.

A neuroscientist says there’s a powerful benefit to exercise that is rarely discussed

The immediate effects of exercise on my mood and thought process proved to be a powerful motivational tool. And as a neuroscientist and workout devotee, I’ve come to believe that these neurological benefits could have profound implications for how we live, learn and age as a society.

Let’s start with one of the most practical immediate benefits of breaking a sweat: exercise combats stress. Exercise is a powerful way to combat feelings of stress because it causes immediate increases in levels of key neurotransmitters, including serotonin, noradrenalin, dopamine and endorphins, that are often depleted by anxiety and depression. That’s why going for a run or spending 30 minutes on the elliptical can boost our moods immediately—combatting the negative feelings we often associate with chronic stressors we deal with every day.

27 Americans were shot and killed on Christmas day

In a grim reminder that violence in America never takes a holiday, 27 people were killed and 63 injured in shooting incidents on Christmas Day this year, according to the Gun Violence Archive. This tally does not include people who shot themselves in suicide.

The number of Americans killed in gun homicides on Christmas Day is comparable to the number of people killed in gun homicides in an entire year in places like Australia or Britain. The 27 people killed by guns in America on Christmas this year is equal to the total number of people killed in gun homicides in an entire year in Austria, New Zealand, Norway, Slovenia, Estonia, Bermuda, Hong Kong and Iceland, combined.

Junk food is tricking your brain: The depressing science behind your binging

Eating for the sake of pleasure, rather than survival, is nothing new. But only in the past several years have researchers come to understand deeply how certain foods—particularly fats and sweets—actually change brain chemistry in a way that drives some people to overconsume.

Scientists have a relatively new name for such cravings: hedonic hunger, a powerful desire for food in the absence of any need for it; the yearning we experience when our stomach is full but our brain is still ravenous. And a growing number of experts now argue that hedonic hunger is one of the primary contributors to surging obesity rates in developed countries worldwide, particularly in the U.S., where scrumptious desserts and mouthwatering junk foods are cheap and plentiful.

No, Lettuce Is Not Worse For The Environment Than Bacon

If you follow the intersection of food and climate change, you know that you can barely swing a reusable grocery bag these days without running into a new study or article bemoaning the environmental damages of a meat-heavy diet.

So imagine the joy that must have leapt into meat-eaters’ hearts when Tuesday, media outlets from around the world ran a story claiming that the environmental villain lurking in your refrigerator is not that salty slab of bacon, but that crisp head of lettuce hiding innocently in the salad drawer.

“Bacon lovers of the world, rejoice!” cried one article in Climatewire.

That celebration, however, should be short-lived. Sorry to break it to you, meat enthusiasts, but bacon isn’t necessarily better for the environment than lettuce.

The issue is that the original Carnegie Mellon study on which the claim was based looked at energy, water use, and greenhouse gas emissions on a per calorie basis.

The sad economics of internet fame

It was all so painfully awkward. That night, Brittany Ashley, a lesbian stoner in red lipstick, was at Eveleigh, a popular farm-to-table spot in West Hollywood. The restaurant was hosting Buzzfeed’s Golden Globes party. For the past two years, Ashley has been one of the most visible actresses on the company’s four YouTube channels, which altogether have about 17 million subscribers. She stars in bawdy videos with titles like “How To Win The Breakup” or “Masturbation: Guys Vs. Girls,” many of which rack up millions of views.

The awkward part was that Ashley wasn’t there to celebrate with Buzzfeed. She was there to serve them. Not realizing that her handful of weekly waitressing shifts at Eveleigh paid most of her bills, a coworker from the video production site asked Ashley if her serving tray was “a bit.” It was not.

The question sent Ashley into a depressive spiral. Hers just wasn’t the breezy, glamorous life people expected from her. Customers had approached her at work before, starstruck but confused. Why would someone with 90,000 Instagram followers be serving brunch?

Simple: because Ashley needed the money.

Bad girls and gone girls: Why the media tired of ‘missing white women’

You remember their names, because the media wouldn’t let you forget them: Laci Peterson, Natalee Holloway, Elizabeth Smart, Chandra Levy, Lori Hacking — young women who disappeared under mysterious circumstances. Gone girls.

Then there were the bad girls. Young women accused of murder — Amanda Knox, Casey Anthony,Jodi Arias. The long-running investigations into their alleged crimes were the stuff of equally obsessive coverage.

But as 2015 creeps toward a close, the gone girls and bad girls have all but disappeared from the media map. The era in which the national news media regularly manufactured folk heroines and anti-heroines from the crime blotter seems to have passed.

The Real Face of Jesus

From the first time Christian children settle into Sunday school classrooms, an image of Jesus Christ is etched into their minds. In North America he is most often depicted as being taller than his disciples, lean, with long, flowing, light brown hair, fair skin and light-colored eyes. Familiar though this image may be, it is inherently flawed. A person with these features and physical bearing would have looked very different from everyone else in the region where Jesus lived and ministered. Surely the authors of the Bible would have mentioned so stark a contrast. On the contrary, according to the Gospel of Matthew, when Jesus was arrested in the garden of Gethsemane before the Crucifixion, Judas Iscariot had to indicate to the soldiers whom Jesus was because they could not tell him apart from his disciples. Further clouding the question of what Jesus looked like is the simple fact that nowhere in the New Testament is Jesus described, nor have any drawings of him ever been uncovered. There is the additional problem of having neither a skeleton nor other bodily remains to probe for DNA. In the absence of evidence, our images of Jesus have been left to the imagination of artists. The influences of the artists’ cultures and traditions can be profound, observes Carlos F. Cardoza-Orlandi, associate professor of world Christianity at Columbia Theological Seminary in Atlanta. “While Western imagery is dominant, in other parts of the world he is often shown as black, Arab or Hispanic.” And so the fundamental question remains: What did Jesus look like?
