Fish oil supplements linked to lower risk of mortality
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.
