Today’s Headlines: Aspirin, CO2 and Teen Pregnancy

Do not take daily aspirin if you haven’t had a heart attack, says FDA: “Taking a daily aspirin is not necessary for people with no history of heart problems, the U.S. Food and Drug Administration says. In a newly released consumer update bound to cause a stir for the 40 million Americans who take aspirin every day, the FDA says it has combed the evidence and concluded that people who have not had heart problems, even if they have a family history of it, will not benefit from taking a daily aspirin. The announcement comes after the FDA denied Bayer’s request to change its aspirin labels to say aspirin can aid in the prevention of heart attacks in people without a history of heart disease.” (TIME)

High CO2 makes crops less nutritious: Global warming may spell trouble for several important nutrients in our food, according to a new study. In the largest study yet done on the effect of rising CO2 levels and food nutrition, researchers “report that the CO2 levels expected in the second half of this century will likely reduce the levels of zinc, iron, and protein in wheat, rice, peas, and soybeans. Some two billion people, the researchers note, live in countries where citizens receive more than 60 percent of their zinc or iron from these types of crops. Deficiencies of these nutrients already cause an estimated loss of 63 million life-years annually.” (National Geographic)

Teenage pregnancy, birth, abortion rates all falling, report says: Teenage pregnancy, birth and abortion rates have dropped dramatically to some of their lowest levels since they peaked in the 1990s, according to the nonprofit Guttmacher Institute. The teen pregnancy rate dropped 51% between 1990 and 2010 and the abortion rate has dropped 66% since 1988. The report’s authors stated that “fewer teens are becoming pregnant than at any time since tracking of this data began.” These declines were seen in all racial and ethnic groups, and varied by state. New Mexico has the highest rate of teen pregnancies and New Hampshire has the lowest. (Los Angeles Times)
