There's fresh evidence that eating a healthy diet, one that includes plenty of fruits and vegetables and limits highly processed foods, can help reduce symptoms of depression.

Piper Johnson was all packed and ready to drive across country with her mom to start college when the 18-year-old noticed a pain in her chest. She took an Advil and hoped the pain would go away.

It didn't. During the drive from her hometown of New Lenox, Ill., near Chicago, to the University of Northern Colorado in Greeley, Colo., she realized something was very wrong. "I kept feeling worse and worse," Johnson says. She developed a high fever, felt extremely lethargic, and noticed a rapid heart beat.

A new set of analyses published Monday in the Annals of Internal Medicine challenges the widespread recommendations to cut back on red and processed meats.

Packing a turkey sandwich in your kid's lunchbox, or serving up bacon or hot dogs?

When shopping for processed meats, many health-conscious consumers look for products with words like "no nitrates added" or "uncured" on the packaging. But we may have been misled, experts say.

A new report finds that deli meats with those labels actually contain similar levels of nitrates as meats that don't carry these labels.

A 14-year-old boy goes to the doctor with complaints of tiredness. He's an extremely picky eater. (Think a daily diet of French fries, plus snacking on Pringles potato chips, white bread and some processed pork.) But overall, he appears OK. He's not overweight and takes no medications.

Tests show he has anemia and low levels of vitamin B12, so he's given B12 injections and diet advice. But a year later, he has begun to lose his vision. Then, by age 17, he's legally blind.

At a time when more than 30 states and the District of Columbia have legalized the use of marijuana for either medical or recreational use, the U.S. surgeon general says no amount of the drug is safe for teens, young adults and pregnant women.

Virtual reality is not new. But, as people search for alternative ways to manage pain — and reduce reliance on pills — VR is attracting renewed attention.

Imagine, for a moment you've been transported to a sunlit lagoon. And, suddenly, it's as if you're immersed in the warm water and swimming. That's what Tom Norris experiences when he straps on his VR headset.

Emphysema is considered a smoker's disease. But it turns out, exposure to air pollution may lead to the same changes in the lung that give rise to emphysema.

Could it happen here? It's a question a lot of people ask in the wake of a traumatic event.

Even if you're not directly connected to the events in El Paso, Gilroy or Dayton, chances are you've felt the weight of them.

Humans must drastically alter food production to prevent the most catastrophic effects of global warming, according to a new report from the United Nations panel on climate change.

The panel of scientists looked at the climate change effects of agriculture, deforestation and other land use, such as harvesting peat and managing grasslands and wetlands. Together, those activities generate about a third of human greenhouse gas emissions, including more than 40% of methane.
