Abstract
The quantity and makeup of dietary fat intake are known to affect human health. A variety of purported health benefits, including cancer prevention, have focused increased attention on use of omega-3 (ω-3) polyunsaturated fatty acid (PUFA) supplements. Preclinical evidence has been encouraging, and recent studies have increased our understanding of mechanisms by means of which ω-3 PUFAs may protect against breast cancer. However, epidemiological studies have yielded mixed results. Recent population studies have attempted to determine factors, for example total fat intake and the ratio of ω-3 to ω-6 PUFA intake, that may affect the action of ω-3 PUFAs. Several clinical trials, some currently ongoing, are investigating strategies to favorably alter endogenous fatty acid profiles in an attempt to develop clinically feasible prevention methods. Identification of well-defined subpopulations who are most likely to benefit from a targeted prevention approach will probably be crucial to this effort.
