Eating tree nuts, peanuts and peanut butter may help people live longer, a new study suggests. The study looked at diet and death rates for more than 200,000 people. They were part of 3 long-term studies in China and the southeastern United States. The 2 Chinese studies asked people about the amount of peanuts they ate. The U.S. study asked about all nuts, but half of the nuts people ate were peanuts or peanut butter. Overall, people who ate the most nuts consumed about 2 tablespoons a day. Researchers kept track of people for 5.4 to 12.2 years, depending on the study. During follow-up, people who ate the most nuts were 20% less likely to die than those who ate the least. These numbers were adjusted to account for other things that can affect death rates, such as diabetes and smoking. Researches also looked at specific causes of death.
More than 1 in 5 high school girls has been physically or sexually assaulted by someone she dated, a study finds. The study was based on a government survey that is repeated every 2 years. But in 2013, researchers added an extra question about dating violence. The new question dealt specifically with sexual violence. The result was that twice as many girls reported any type of dating violence -- 21%, compared with 9% in 2011. About 10% of boys reported any assault. This was similar to the last survey. Among girls, 7% reported a physical assault and 8% reported a sexual assault by someone they dated. Among boys, 4% reported physical assault and 3% reported sexual assault. About 6% of girls and 3% of boys reported both types of assault. Most teens who had been assaulted said it happened more than once. Teens who were assaulted were more likely to do risky things.
