The Food Fight in Your Gut: Why Bacteria Will Change the Way You Think about Calories

There’s a food fight in your guts. Not the Tater-Tot-chucking, spoonful-of-mashed potato-flinging, melee-in-the-cafeteria type of food fight. Rather, your intestines are the site of an ancient and complex war between your own cells and trillions of bacteria—a war over what happens to your food as it moves through your body. Some of the bacteria form [...]

Large portion sizes: bad for business?

Woman Eating Large Slice Of Pizza

I’m not a big fan of milkshakes. But after a dental operation a few years ago, I decided to try one again. Not too bad, I remember thinking as I sipped the cool, chocolaty concoction. Unfortunately, a bad reaction to my pain medication later that evening meant the milkshake became associated with less than pleasant [...]

I Just Preordered My HAPIfork

Why, oh why, would I order a plastic fork, costing $89 (on-sale), 5 months before its scheduled release? Because it promises to help me control my eating speed, which, I am now convinced, is indeed critical to controlling obesity and diabetes.

Chew on This: More Mastication Cuts Calorie Intake by 12 Percent

chewing on apple

About a century ago, a new craze gripped the country’s health conscious: mastication. Chewing each bite of food precisely 32 times would help people control how much food they consumed—turning them from gluttons to epicureans—according to the early 20th-century dietician Horace Fletcher. Among his many ardent adherents the tactic became known as "Fletcherizing." And Fletcher, [...]

Jaws did not dominate early oceans

fossil fish jaw mandible show evolutionary stability in oceans

Deep in the Silurian seas, some 420 million years ago, a strange structure had just emerged in the bodies of many new vertebrates. Some fish began developing a defined upper and lower jaw that allowed them to devour large and hard-shelled organisms. Today more than 99 percent of vertebrates have these handy eating apparati. But [...]

Repent for Your Sins—or Turn Them into Something Good

Courtesy of jhoana.tamayo via Flickr.

The November/December Scientific American Mind is a tribute to the seven deadly sins. Not that gluttony, envy, greed, sloth, wrath, lust and pride are necessarily laudable traits, but we can learn a lot from them. Some of them can even work in our favor if we know how to harness them. Others, we must simply [...]

Nothing To Gobble At: Social Cognition in Turkeys

Turkeys

We tend to think of the domestic turkey as a fairly unintelligent bird, skilled at little more than waddling around, emitting the occasional gobble, and frying up golden-brown-and-delicious. But they can actually be quite clever.

Once Upon A Time, The Catholic Church Decided That Beavers Were Fish

From time to time, politicians and other rulers-of-men like to categorize the natural world not according to biology, but rather for convenience or monetary gain. Take, for example, the tomato. The progenitor of ketchup is a seed-bearing structure that grows from the flowering part of a plant. It is, by definition, a fruit. In 1893, [...]

Is Meat-Eating A Conservation Tactic?

chicken face

I’ve been thinking a lot lately about wildlife conservation psychology, especially in light of last month’s TEDxDeExtinction event. How do we convince human animals that other animals are worth protecting? Modern, ethical zoos have long made claims about the effectiveness of zoo visits and their in-house educational programs on learning outcomes and on conservation attitudes. [...]

How Anteaters Decide What To Eat

giant anteater

The Giant Anteater, Myrmecophaga tridactyla, only eats ants and termites, as its name suggests. Since the giant anteater and its evolutionary ancestors have been feasting on ants and termites for nearly 60 million years, a researcher named Kent Redford hypothesized that, over time, ants and termites may have evolved various defenses to avoid predation. In [...]

On Capsaicin: Why Do We Love to Eat Hot Peppers?

Stories of pepper spray have been all over the news lately. On Fox News, Megyn Kelly wondered what all the fuss about this “food product” was, and while pepper spray is no vegetable, the compound that makes pepper spray into a weapon at 2-5.3 million Scoville units, is indeed the same compound that many humans [...]

Chicken Soup for the Lonely Soul: Why Comfort Food Works

My grandmother was born in Sobrance, in what was then called Czechoslovakia on November 5, 1930. She grew up in ten kilometers away, in a small town called Nagy-Muzsaly. Her father’s family were landowners, something that was very rare for Jewish families at the time, and they used that land to produce wine. My grandmother’s [...]
