Fish oil sup­ple­ments linked to lower risk of mor­tal­ity

Pretoria News - - LIFESTYLE -

REG­U­LAR use of fish oil sup­ple­ments may be linked to a lower risk of death and car­dio­vas­cu­lar dis­ease (CVD) events, such as heart at­tack and stroke, say re­searchers.

Fish oil is a pop­u­lar di­etary sup­ple­ment in de­vel­oped coun­tries. Some ev­i­dence sug­gests that omega-3 fatty acids in fish oil may help pre­vent car­dio­vas­cu­lar dis­ease and re­duce mor­tal­ity, but con­clu­sive ev­i­dence is still lack­ing.

For the find­ings, pub­lished in the jour­nal the BMJ, the re­search team from South­ern Med­i­cal Univer­sity in China and Brown Univer­sity in the US drew on data from the UK Biobank – a large pop­u­la­tion based study of more than half a mil­lion Bri­tish men and women.

Their anal­y­sis in­cluded 427 678 men and women be­tween 40 and 69 years old, with­out CVD or can­cer, who were en­rolled in the study from 2006 to 2010 and com­pleted a ques­tion­naire on sup­ple­ment use, in­clud­ing fish oil.

The re­searchers found that fish oil sup­ple­ments were as­so­ci­ated with a 13 % lower risk of all-cause mor­tal­ity, a 16% lower risk of CVD mor­tal­ity, and a 7% lower risk of CVD events.

The as­so­ci­a­tion be­tween fish oil use and CVD events ap­peared to be stronger among those with high blood pres­sure, the study said.

These favourable as­so­ci­a­tions re­mained af­ter tak­ing ac­count of tra­di­tional risk fac­tors, such as age, sex, life­style habits, diet, med­i­ca­tion and other sup­ple­ment use.
