low-fat or nonfat milk may be linked to an increased risk of prostate cancer. Take a look:Reuters reports,
A total of 82,483 men from the study completed a quantitative food frequency questionnaire and various factors, such as weight, smoking status, and education levels were also noted, Park's group said.
During an average follow-up period of 8 years, 4,404 men developed prostate cancer. There was no evidence that calcium or vitamin D from any source increased the risk of prostate cancer. This held true across all racial and ethnic groups.
In an overall analysis of food groups, the consumption of dairy products and milk were not associated with prostate cancer risk, the authors found. Further analysis, however, suggested that low-fat or nonfat milk did increase the risk of localized tumors or non-aggressive tumors, while whole milk decreased this risk.
In a similar analysis, Dr. Yikyung Park, from the National Cancer Institute at National Institutes (NIH) of Health in Bethesda, Maryland, and colleagues investigated the relationship of calcium and vitamin D and prostate cancer in 293,888 men enrolled in the NIH-American Association of Retired Persons Diet and Health Study, conducted between 1995 and 2001. The average follow-up period was 6 years.
