Researchers at the National Institutes of Health found men who ate the most high-fat food had a 53 percent increased risk for pancreatic cancer compared to men who ate the least fattening food. Women who ate the most fat had a 23 percent higher risk for the disease.

Experts say the study is limited because it depends on participants remembering their food habits. They also can't rule out other factors common among people who eat meat as causing the increased risk.

Skewed Body Image
A new study shows overweight children tend to underestimate their weight.

In a study of about 400 children based on body mass index, 40 percent of the children were considered overweight, but nearly a third of those kids said their weight was either normal or lower than what it should be.

Nearly half of the surveyed students said they were trying to lose weight but weren't eating healthier or exercising any more than kids who weren't trying to shed pounds.

Back Improvements Help More Than Aches and Pains
Working on a child's back may prevent asthma, allergies, chronic ear infections, and even problems with sleep. It could be because nerves along the spine can cause problems in other parts of the body.

A 2007 safety review found that injuries were rare, but some medical experts worry that one wrong move could seriously injure a child. A recent National Institutes of Health report found that three percent of American children were treated by a chiropractor, making it the second-most common type of alternative medicine for children.

Sitting Up Straight Causes Strain
It seems that sitting up straight, something many of us are taught from a very early age, is not good for your back.

Many of us spend hours each day sitting in a chair.

"I basically sit in the chair most of the day. When i was younger, my mother would always continually reminding me to sit up straight on the chair", librarian Sally Barans said.

However, a new study suggests that's not the best position for your back.

"If you sit complete 90-degree angle, there is more pressure place on the disk, sitting in the slouching position which is less than 70 degrees basically means a lot of pressure in disk as well. But the research shows that when you lean back there is less pressure on the disks", doctor Kyle Bowers said.

Researchers say a 135-degree position is best for backs, but they say people should get out of their chairs more often.

"Our spines are not designed to be so sedentary."

You can relieve back pain with simple exercises with your chair.

"Good stretch while you are sitting in the chair is basically place your hand back part of your hips and than just bend stretch backward extenuation because that will stretch the lumbar erector muscle as well. The most important stretch to do is to stretching hamstring. You can put your foot on the chair and bend in to that foot there and hold that for about eight seconds."

That should stretch and release tightness. Doctors also suggest to do leg lifts and stretches while doing other office work such as taking calls or running errands.
