　　Doctors tell us eating lots of vegetables is good for our heart health.But a new study finds that eating a lot of vegetables may not greatly reduce(减少)the chance of getting heart problems.
　　Almost400,0o0people from different places took part in the study.They answered questions about their lifestyle,food,and what raw(生的)and cooked vegetables they ate.The study found a result:The chance of dying from heart problems was about15%lower for people eating the most vegetables,especially (尤其是)raw vegetables.
　　However,scientists explained that many other things also have something to do with this15%drop(下降).They may also influence our heart healthjust like vegetables,such as things we eat,how much exercise we get,where we live,and whether(是否)we smoke.Dr.Qi said,“Our study did not find evidence(证据)that eating a certain amount of(一定量的)vegetables can greatly cut down the chance of getting heart problems."
　　But does it mean eating vegetables is not useful?No.Many other scientists advise people to eat at least five kinds of fruit and vegetables every day.They are important for keeping good health and reducing the chance of getting serious illnesses.
