In reply: Sherriff is correct in pointing out that the studies showing protection from bronchial asthma (and bronchial hyperresponsiveness) are based on consumption of fish meals rather than a direct measure of omega-3 fatty acid intake. This protection has been observed consistently in cross-sectional studies of New South Wales primary school children. Thus, the level of evidence is at best Level III, albeit using a proxy for omega-3 fatty acid intake.
