Washington: You may want to start snacking on fresh fruit every day as a new study has found that people who do so are at lower risk of heart attack and stroke than the ones who don't.

Researchers from the University of Oxford and Chinese Academy of Medical Sciences conducted a large, nationwide study of 500,000 adults from 10 urban and rural localities across China, tracking health for 7 years through death records and electronic hospital records of illness.

The study found that fruit consumption (which was mainly apples or oranges) was strongly associated with many other factors, such as education, lower blood pressure, lower blood glucose, and not smoking.

But, after allowing for what was known of these and other factors, a 100g portion of fruit per day was associated with about one-third less cardiovascular mortality and the association was similar across different study areas and in both men and women.

Study author Dr Huaidong Du said that the association between fruit consumption and cardiovascular risk seems to be stronger in China, where many still eat little fruit, than in high-income countries where daily consumption of fruit is more common. 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.

Co-author Professor Liming Li said that a recent Global Burden of Disease report put low fruit consumption as one of the leading causes of premature death in China. However, this was based on little evidence from China itself.

Senior author Zhengming Chen said that it's difficult to know whether the lower risk in people who eat more fresh fruit is because of a real protective effect. If it is, then widespread consumption of fresh fruit in China could prevent about half a million cardiovascular deaths a year, including 200,000 before age 70, and even larger numbers of non-fatal strokes and heart attacks.
