On the basis of the results of our study, we suggest that a higher intake of dairy fat, which primarily comprises saturated fat (1), may be associated with an elevated risk of ischemic heart disease (IHD). Because pentadecanoic acid (15:0) is a marker of dairy fat rather than of total dairy products, these results should not be interpreted as pertinent to the intake of nonfat dairy products, including skim milk. In our previous analyses of dietary data from the Nurses' Health Study, whole milk intake was associated with an increased risk of IHD, whereas skim milk intake was associated with a lower risk (2).
