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 present study was among people who did not have a history of cardiovascular diseases or anti-hypertensive treatments when first joined the study.
Fruit is a rich source of potassium, dietary fibre, antioxidants, and various other potentially active compounds, and contains little sodium or fat and relatively few calories. 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.
