Extended use of proton pump inhibitors (PPIs), a popular type of heartburn drug, dramatically increases the risk of death. This was the conclusion of a team of researchers from the Washington University School of Medicine after analyzing medical data of some 300,000 people.

New data compiled from hundreds of health agencies reveals the extent of the drug overdose epidemic last year as overdoses are now the leading cause of death among Americans under 50.

A healthy 16-year-old boy died last month from ingesting too much caffeine in a short space of time, according to the county coroner. Davis Allen Cripe drank a large Diet Mountain Dew, a cafe latte from McDonald’s and an energy drink within two hours.

A new study from Tufts University found diet to be the cause behind half of all heart disease, stroke and diabetes deaths. Researchers warn that these dietary habits not only influence many of the risk factors for health, but also pose substantial health and economic burdens.
