Less salt and fat. More whole grains, fruit, veggies and low-fat dairy. This is what kids can expect in the school lunchroom soon, according to new nutrition standards for school meals announced today by the U.S. Department of Agriculture and first lady Michelle Obama.

MELISSA BLOCK, HOST:

You can buy Twinkies on the cheap right now. Safeway, just around the corner from our office here in Washington, has them on sale - two boxes for five bucks. So the NPR Science Desk was inspired to take part in the fine, long-standing tradition of experimenting with Twinkies.

NPR's Allison Aubrey reports on their findings.

ALLISON AUBREY, BYLINE: My colleagues, Julie Rovner, our health policy correspondent, and Adam Cole, a new addition to our team, had one idea.

So, what is your experiment, guys?

You may remember the controversial studies linking food coloring and additives to hyperactivity in kids. Or you may know parents who have pinned their hopes on an elimination diet to improve their kids' rowdy behavior.

If you feel hungrier as winter draws near, you're not alone. Even though most of us spend our days in climate-controlled offices and homes, our appetites seem to change when the days grow shorter. Some researchers say it's our primitive impulses promting us to stockpile calories for the winter ahead.

Corporate America is jumping on the opportunities to make people healthier, while keep their bottoms line strong. Leaders of Supermarkets, hotel chains and restaurant groups gathered in Washington this week for a summit aimed at shaping private sector solutions to the obesity epidemic.

When I heard Paula Deen was coming to town, the image that leaped to mind was a fried cheesecake, deep-fried. She actually makes this!

At a time when it's trendy to take things out of food (think: gluten-free, sodium-free, fat-free), Paula Deen unapologetically puts it all back in. She loves all that stuff we're told to eat less of: butter, mayonnaise, sour cream. Did I say butter?

A decade ago there were fewer than 100 Narragansett turkeys being raised on a few hobby farms. The gamy-tasting meat has a flavor that most Americans have never tasted. "They're delicious," says Slow Food USA's Josh Viertel.

"And they're at risk of being gone forever."

For as long as there's been an IQ test, there's been controversy over what it measures. Do IQ scores capture a person's intellectual capacity, which supposedly remains stable over time? Or is the Intelligent Quotient exam really an achievement test — similar to the S.A.T. — that's subject to fluctuations in scores?

The findings of a new study add evidence to the latter theory: IQ seems to be a gauge of acquired knowledge that progresses in fits and starts.

It seems that all the big farm groups - from beef and pork producers to sugar and soybean growers — have been paying attention to those "Know Your Farmer" bumper stickers.

Contestants on the Season 12 Premiere of TV's The Biggest Loser last night may not be the only people motivated to lose weight. Viewers are influenced by weight-loss reality shows, too.

Menus at Olive Garden and Red Lobster are about to get a health makeover. Darden Restaurants, which owns the brands, is the latest corporation to collaborate with First Lady Michelle Obama's Let's Move! campaign aimed ending childhood obesity.

Terrified to see your teenager behind the wheel? You're not alone. But a new study finds tougher state licensing laws have led to a decrease in fatal accidents, at least among 16-year-olds. That's the good news.

About half of adult smokers who live with young children say they don't smoke in the house. But that leaves the rest who do.

And the children of these at-home smokers --according to a study just published in the journal Pediatrics — are missing more days of school.

As kids head back to class the dreaded back-to-school bugs begin to spike. Sniffles and sneezes are inevitable, but there are also stomach bugs.

And parents may never have considered how one part of the morning routine may increase their children's odds of getting an upset stomach. It's the packing of lunch with just typical foods.

If you've got high cholesterol, you know the diet advice: Go easy on foods high in saturated fat like red meat and cheese, and eat lots of fiber and whole grains.

The message still holds up, but researchers say it's time to tweak the message.

Kids may claim that Tater Tots are the only edible food in the school cafeteria, but in reality, school lunches are getting more healthful.

Almost all cafeterias now serve fresh fruits and vegetables, according to a survey of school food directors released Thursday. Whole grains are readily accessible in 97 percent of schools, and 89 percent of districts offer salad bars or pre-packaged salads. Gone are the days of full fat milk; virtually all districts offer skim or 1 percent.

Let's begin with some well-worn advice: Moderation is key. So go ahead and eat that hot dog at the state fair or some bacon on vacation. But take note: People who eat lots of processed meats over their lifetime seem to have a higher risk of developing Type 2 diabetes (and heart disease).

With one death and 77 people reported ill, the latest foodborne illness outbreak has led to one of the largest recalls in U.S. history. Food giant Cargill has been forced to pull a staggering 36 million pounds of ground turkey from the market. And the victims in this case have gotten very sick — almost one-third have ended up in the hospital.
