[Relationship between diet, nutritional status and prostatic cancer].
Several epidemiological investigations suggest an association between diet and prostatic cancer. The most consistent finding has been a risk-enhancing effect of a diet rich in fat, especially animal fat. There is some evidence that dietary fat acts in late prostatic carcinogenesis by promoting the progression from focal to clinical disease, and that this effect may be due to an influence on the hormonal system. Data on other dietary factors, especially vitamin A and beta-carotene, are equivocal. This is probably partly due to the fact that most of the epidemiological studies have been based on limited dietary information. It is unclear whether the nutritional status influences the development of prostatic cancer, and if so, which anthropometric measurements are associated with an increased risk. Future studies should aim at estimating dietary exposures more precisely than hitherto by using calibrated dietary assessment methods that permit adjustment for total energy intake and combining these with biochemical methods. It will also be important to further investigate relations between diet, nutritional status and the hormonal system.
