When it comes to walking, the easy part is understanding the benefits: Regular, brisk walks can strengthen our bones, help control blood sugar, help lower blood pressure and cholesterol, and the list goes on. The hard part is finding the time to fit it in.

Engineering physical activity back into Americans' daily lives is the goal of an educational campaign launched by Kaiser Permanente,an Oakland, Calif.-based health plan.

There are tons of tips and resources online, with the goal of creating a culture of walking. Kaiser Permanente even seems to be walking the walk with its own employees.

Got a Diet Coke or Diet Pepsi habit? Lots of Americans do. Consumption of all types of diet soft drinks has been on the rise. And as a nation, we drink an estimated 20 percent more of diet drinks now than we did 15 years ago.

So, is it good for us? A new study finds the answer to that question may depend a lot on, well, what you eat.

Researchers at the University of North Carolina-Chapel Hill found that diet soda drinkers who ate a so-called "prudent" diet, rich in fruit, fish, vegetables, whole grains, nuts and milk, were significantly less likely to develop metabolic syndrome over 20 years than those who ate a "Western diet" heavy in fried foods, meats and sugars.

Thiamine mononitrate, disodium inosinate, pyridoxine hydrochloride.

Why are these hard-to-pronounce ingredients added to everything from a burger served in schools to veggie burgers in the frozen food aisle of the grocery store? We try to answer that on this edition of Tiny Desk Kitchen.

It turns out the answers are as varied as the ingredients. But as we yearn to know what's in our food and how it's made, these kinds of ingredients with unfamiliar names make people suspicious.

"For me, it's just a huge red flag," says Ryan Lonnett, a parent of children in Fairfax County, Va., schools. He's an advocate with the group Real Food For Kids.

A new study finds that people who eat chocolate several times a week are actually leaner than people who don't eat chocolate regularly.

Really, we asked? Last time we checked chocolate was loaded with fat and sugar. But this new research, along with some prior studies, suggests chocolate may favorably influence metabolism.

Bacon has been called the gateway meat, luring vegetarians back to meat. And hot dogs are a staple at many a backyard BBQ.

But a new study published in the Archives of Internal Medicine finds that daily consumption of red meat — particularly processed meat — may be riskier than carnivores realize.

"The statistics are staggering," study author Frank Hu, a professor of nutrition and epidemiology at the Harvard School of Public health, told us. "The increased risk is really substantial."

No need to be stingy with spices. Research from Penn State finds heavily spiced meals — think chicken curry with lots of turmeric, or desserts rich in cinnamon and cloves — may do the heart good.

"Elevated triglycerides are a risk factor for heart disease," explains researcher Sheila West.

Her study found that a spicy meal helps cut levels of triglycerides, a type of fat, in the blood — even when the meal is rich in oily sauces and high in fat.

In fact, she documented a decrease of triglycerides by about one-third. This compares with people who ate the same meal, but prepared without spices.

"It was surprising," West told us. "I didn't expect such a large decrease."

Have you ever splurged on a highly rated bottle of Burgundy or pinot noir, only to wonder whether a $10 or $15 bottle of red would have been just as good? The answer may depend on your biology.

A new study by researchers at Penn State finds that when it comes to appreciating the subtleties of wine, experts can taste things many of us can't. "What we found is that the fundamental taste ability of an expert is different," says John Hayes of Penn State.

So what explains this? Part of it has to do with training and experience. But our ability to identify nuances in wine is also influenced by physiology in our mouths and brains.
