In addition to all of the other claimed health benefits for Docosahexanoic acid (DHA), an omega-3 fatty acid, it seems to enhance the function of the chemotherapy drug cisplatin.

"DHA elicited prominent chemopreventive effects on its own, and appreciably augmented those of cisplatin as well. Furthermore, this study is the first to reveal that DHA can obliterate lethal cisplatin-induced nephrotoxicity and renal tissue injury." . . .

"While DHA has been tentatively linked with protection against cardiovascular, neurological and neoplastic diseases, there exists a paucity of research information, in particular regarding its interactions with existing chemotherapy drugs". The researchers found that, at the molecular level, DHA acts by reducing leukocytosis (white blood cell accumulation), systemic inflammation, and oxidative stress – all processes that have been linked with tumour growth.

It's not usually mentioned in press releases but one of the best, most sustainable sources of DHA is from grass fed ruminant meat and dairy products, especially the dairy products such as cheese since they concentrate the DHA. When the health benefits of such foods is combined with the environmental benefits of producing them (See Cereal Killer for a recent account) a compelling case for such foods emerges.
