Researchers from Sweden suggest that there is a strong link between processed meats, such as sausage and bacon, and pancreatic cancer. Eating 50 grams of processed meats every day -- the equivalent of one sausage or two pieces of bacon -- can increase the risk of pancreatic cancer by 19 percent, compared to those who do not eat processed meats of any kind. For those who consume double the amount of processed meats, 100g per day, the increased risk also doubles to 38 percent. But while...

Drinking at least one cup of coffee per day could reduce a woman's risk of stroke by as much as 25%, claims a new study published online Thursday in the American Heart Association journal Stroke. Dr. Susanna Larsson, a researcher in the Division of Nutritional Epidemiology, National Institute of Environmental Medicine, Karolinska Institute in Stockholm, Sweden, and colleagues studied more than 34,000 women between the ages of 49 and 83, following them for an average period of 10.4 years....

In a large natural disaster, such as the Haitian earthquake earlier this year, or in an unsolved homicide case, knowing the birth date of an individual can guide forensic investigators to the correct identity among a large number of possible victims. Livermore researcher Bruce Buchholz and colleagues at the Karolinska Institute are looking at victim's teeth to determine how old they are at the time of death. Using the Lawrence Livermore's Center for Accelerator Mass Spectrometry, Buchholz...

New research has found that getting a little more calcium in your diet could help you live longer, Reuters reports. Swedish researchers conducted a study which found that men who consumed the most calcium in their diets were 25 percent less likely to die over the next decade than their peers, who had the least amount of calcium in their diets.  None of the men studied took calcium supplements.
