  nificantly reduced levels of C28 –C36
  carbon-containing hydroxylated poly-
  unsaturated ultra-long-chain fatty acids
  in all three independent cohorts of
  colorectal cancer (CRC) patient
  samples relative to controls. “These
  metabolites are easily measurable in
  serum and a decrease in their con-
  centration appears to be highly sen-
  sitive and specific for the presence
  of CRC, regardless of ethnic or geo-
  graphic background,” the authors write
  in BMC Medicine (doi: 10.1186/1741-
  7015-8-13). “The measurement of
  these metabolites may represent an
  additional tool for the early detec-
  tion and screening of CRC,” they con-
  clude. The complete article is available

Description: The multicenter clinical trial of 224 postmenopausal women - led by D. Lee Alekel, professor of nutrition and interim associate director of the Nutrition and Wellness Research Center (NWRC) at ISU and supported by the National Institute of Arthritis, Musculoskeletal and Skin Diseases, one of the research institutes of the National Institutes of Health (NIH) - was the longest ever conducted on the effects of soy isoflavones on bone mineral density (BMD).
