Research has shown that sharp reductions in the amount of food consumed can help fish, rats and monkeys live longer. But there have been very few studies in humans.

Now, some researchers have found that when people severely cut calories, they can slow their metabolism and possibly the aging process.

New research published Monday adds fuel to an ongoing debate in the public health community over whether a few extra pounds are good, or bad, for you.

Earlier research found that being somewhat overweight, but not obese, may result in a longer life.

Peanut allergies can be among a parent's biggest worries, though we've had good evidence for more than a year that when most babies are 6 months old or so, introducing foods that contain finely ground peanuts can actually reduce babies' chances of becoming allergic to the legumes. Even so, many parents are scared to do that.

There are rating systems for hospitals, nursing homes and doctors. So why is it so hard to compare providers of child care?

Part of the reason is that there are no nationally agreed-upon standards for what determines the quality of child care. The standards that do exist are formulated in each state, and they vary widely.

For example, some states require that child care workers have a teaching certificate. Others require certain college courses. Some have strict ratios of how many caregivers are required per child.

If you had chickenpox as a child, then you're at risk for shingles. As you age, the risk increases, probably because the immune system weakens over time.

The varicella zoster virus can hide in the body over a lifetime and suddenly activate, causing a painful, blistery rash. Even when the rash disappears, pain can linger and worsen, causing a burning, shooting, stabbing pain so severe it can leave people unable to sleep, work or carry on other activities.

This makes total sense: When you're engaged in an activity you truly enjoy, you're happy. And, when you're happy you're not dwelling on all the negative things in life, nor are you stressed about obligations or problems. Certainly this is a good thing from an emotional point of view, but it also has physical benefits.

We know exercise reduces stress, but it turns out that more simple stationary things, like doing puzzles, painting or sewing can help, too.

First off, I need to be upfront: I have a treadmill desk. I got it about two years ago, prompted by all the studies showing the dangers of sitting all day. The idea is to get people more active and walking while working. The problem is, I don't use it. In fact, I probably only used it for a few months. I still stand all day, but I'm not walking.

Suicide rates in the U.S. have gone up considerably in recent years, claiming an average of 36,000 lives annually.

Most people take their lives in or near home. But suicide on the job is also increasing and, according to federal researchers, suicide risk changes depending on the type of work people do.

Researchers from the National Institute for Occupational Safety and Health analyzed census data and compared suicide rates among different occupations.

When you ask people what impacts health you'll get a lot of different answers: Access to good health care and preventative services, personal behavior, exposure to germs or pollution and stress. But if you dig a little deeper you'll find a clear dividing line, and it boils down to one word: money.

For most of her life Fran Friedman struggled with compulsive eating. At 59 years old she was 5 foot 2 and weighed 360 pounds. That's when she opted for bariatric surgery.

The surgery worked. Friedman, who is now 70 and lives in Los Angeles, lost 175 pounds. "It was a miracle," Friedman says, not to feel hungry. "It was the first time in my life that I've ever lost a lot of weight and was able to maintain it."

People who try to reduce the stress of a long work day with a drink or two, or three, may be causing more health problems for themselves.

Around the world, people working long hours are more likely to drink too much, according to a study that analyzed data from 61 studies involving 333,693 people in 14 countries.

They found that people who worked more than 48 hours a week were 13 percent more likely to engage in risky drinking than people working 35 to 40 hours a week.

Cancer doctors want the best, most effective treatment for their patients. But it turns out many aren't paying attention to evidence that older women with early stage breast cancer may be enduring the pain, fatigue and cost of radiation treatment although it doesn't increase life expectancy.

Lots of things can trigger an asthma attack, but one of the most common causes is odor — anything from the heavy scent of perfume to a household cleaner.

The symptoms of the flu are familiar: fever, chills, cough, congestion, feeling very, very tired. If you're a healthy adult under 65, you'll most likely recover in a week or two.

But for those older than 65, things can get worse fast, says Dr. H. Keipp Talbot, an infectious disease specialist at Vanderbilt University.

For Lori Bandt, who works as a medical technician and an EMT in a suburb of Madison, Wis., the print on vials of medication has become so difficult to read that if she forgets her reading glasses she has to resort to having a younger EMT worker read the directions. The 45-year-old says: "I'm just stuck."

Until recently, freezing a woman's eggs was reserved mainly for young women facing infertility as a result of cancer treatments like chemotherapy.

But recent advances in technology have made freezing eggs easier and more successful, and likely have a lot to do with the recent decisions by Facebook and Apple to offer female employees a health benefit worth up to $20,000 to freeze their eggs.

On a recent Sunday night, Liz Paul was tired. She'd worked in the morning, spent a full day with her family and she did not feel like going out for her daily jog.

"I tweeted out, 'Well, it's 9 p.m. on Sunday and I didn't work out,' " she says, "I really shouldn't go run in the dark should I?"

The response was immediate. The network of people Paul is relying on to help in her battle to lose weight chimed in with advice. Some tweeted back, "Yes, get out and run." Others offered alternatives like a video workout. But everyone said, "Do something!"

Chronic stress is hazardous to health and can lead to early death from heart disease, cancer and other health problems. But it turns out it doesn't matter whether the stress comes from major events in life or from minor problems. Both can be deadly.

And it may be that it's not the stress from major life events like divorce, illness and job loss trickled down to everyday life that gets you; it's how you react to the smaller, everyday stress.

The most stressed-out people have the highest risk of premature death, according to one study that followed 1,293 men for years.

There's no question that alcohol is a factor in the majority of sexual assaults on campus. And alcohol is abundant and very present at most colleges today.

In fact, federal health officials say more than 80 percent of college students drink. And about half say they binge drink. This means more than four drinks for women and more than five drinks for men, within a two-hour time frame.

When people lose their vision as they get older, they lose a lot of other things, too. They lose their ability to do the things they love.

"You can't read, you can't cook, and you can't socialize — and as a result, you may become demoralized, withdrawn and depressed," says Dr. Barry Rovner, a geriatric psychiatrist at Thomas Jefferson University in Philadelphia.

We're constantly hearing messages that we're eating too much and not moving around enough. Now researchers suggest that we're actually not eating more than we did 20 years ago, it's that we're much less active. And that includes not just middle-aged workers tied to their desks, but also young men and women who spend their days sitting in front of their laptops.

We know that happiness and social connection can have positive benefits on health. Now research suggests that having a sense of purpose or direction in life may also be beneficial.

Many people are intensely interested in how publicly funded charter schools affect children, and that includes not just their academic achievement but their health.

Researchers from UCLA and the Rand Corp. wanted to know whether attending a high-performing charter school reduced the rates of risky health behaviors among low-income minority teenagers.

Stress is part of the human condition, unavoidable and even necessary to a degree. But too much stress can be toxic — even disabling.

And there's a lot of toxic stress out there.

A national poll done by NPR with our partners at the Robert Wood Johnson Foundation and the Harvard School of Public Health finds that more than 1 in every 4 Americans say they had a great deal of stress in the previous month.

As a child, Diany Levy was called lazy and unfocused. She remembers that teachers called home on a daily basis to tell her parents she was not paying attention in class. Now, at the age of 23, Diany has finally been diagnosed with the cause of her problems – ADHD.
