As we celebrate Father’s Day this weekend, many of us will feel grateful for dads’ presence in our lives and also for their good health. Vanderbilt University scholars Derek Griffith and Elizabeth Stewart, who study men’s health, take this opportunity to explain to us that fathers’ health is not something to take for granted.

In fact, their recent research reveals that fatherhood can sometimes detract from good health. While fathers want to be healthy, they often ignore their health needs, the scholars suggest. Why? Many see their ability to hold down a well-paying job as the most important thing they do for their families. As a result, they often fail to eat healthfully, exercise and see doctors when they should.

Also today: why divorced dads often feel ignored by their kids’ schools, a newly discovered species of bacteria that lives in seaweed, and how the U.S. Defense Department contributes to climate change.
