Prostate cancer risk poorly related to fat intake

September 14, 1999

NEW YORK (Reuters Health) -- Contrary to previous reports, the risk of developing prostate cancer depends only slightly on the consumption of certain specific types of fat, according to Dutch researchers.

"(Our) data suggest that certain fatty acids might be involved in prostate carcinoma occurrence, although the possibility that these were chance findings cannot be ruled out," writes Dr. Agnes Schuurman of Maastricht University in the Netherlands, along with her colleagues in the Netherlands Cohort Study. Their results are published in the September 15th issue of Cancer.

The investigators used questionnaire responses obtained from 58,279 men to compare the dietary habits of 642 men who developed prostate cancer with those of 1,525 men who did not, the report indicates.

"No associations were observed for intake of total energy, total fat, total fatty acids, saturated fatty acids, and trans unsaturated fatty acids," the investigators report.

Slight associations were found between prostate cancer risk and certain fatty acids, the authors write. The results suggest a slight increase in risk with consumption of oleic acid and a slight decrease in risk with consumption of linoleic acid and linolenic acid.

Oleic acid is found in canola oil, corn oil and olive oil, as well as in artificial butters and cheeses. Linoleic acid and linolenic acid are found in fish, canola, and linseed oils, and from a variety of other foods.

"In conclusion," the scientists write, "in our study we found no evidence of a strong association between energy or fat intake, or intake of a number of specific fatty acids, and prostate cancer risk. However, there was a suggestion of (an increased risk) for intake of oleic acid and (a decreased risk) for intake of linoleic acid and linolenic acid."

"A geographic variation in prostate cancer incidence around the world tells us that environmental factors such as diet may play an important role in the disease," Schuurman comments in a statement to the press. "This evidence sheds more light on the important question of which foods in a man's diet might increase or decrease his risk for prostate cancer. This brings us closer to an answer."
