Five fruit and vegetables a day

This paper describes the effect of fruit and vegetable intake on the chances of developing cancer. The population studied was 500, 000 people or so, aged 25 to 75 from 10 Western European countries. . There is virtually no benefit of 5 fruit and vegetables a day for cancer protection. 200 g of fruit and vegetables reduce the risk by 3 %, five a day and the risk is reduced 9%. Though there is benefit in protection against mouth, oesophageal , colon and lung cancer. Fruit and vegetable ingestion protects against heart and stroke risk. ( for strokes a 26% reduction ) .
These conflicting results form earlier studies may be a result of the type and number of control subjects.
