Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being very overweight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts （内脏）when you were a baby and the chance that you would become overweight?

Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.

You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.

Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.

So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.

To get an extra 14 years of life, don’t smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount. That is according to a study published this Monday in the Public Library of Science Medicine Journal.

    After tracking more than 20,000 people aged 45-79 years in the United Kingdom from about 1993-2007, Kay-Tee, Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived an average of 14 years longer than those who didn’t.

“We’ve known for a long time that these behaviors are good things to do, but we’ve not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain’s Medical Research Council. “The benefit was also seen regardless of whether or not people were fat and what social class they came from.”

Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
