There seems to be some truth in the old saying: "An apple a day keeps the doctor away. "A new study in the Chinese population said Wednesday that people who eat fresh fruit on most days are at lower risk of heart attack and stroke than people who rarely eat fresh fruit.

The participants did not have a history of cardiovascular （心血管）diseases or anti-hypertensive （抗高血压）treatments when they first joined the study.

Also, fruit in China is almost exclusively consumed raw, whereas much of the fruit in high-income countries is processed, and many previous studies combined fresh and processed fruit, said Du.
