Omega-3 fatty acids re­duce risk of death from heart at­tack

Pakistan Observer - - KARACHICITY - STAFF RE­PORTER

Eat­ing foods rich in omega-3 fatty ac ids may lower the risk of death from heart at­tack. This is the find­ing of new re­search pub­lished in JAMA In­ter­nal Medicine.

Eat­ing foods rich in omega-3 may re­duce the risk of death from heart at­tack, say re­searchers. Each year, around 735,000 peo­ple in the United States have a heart at­tack, which oc­curs when a sec­tion of the heart fails to re­ceive enough oxy­gen-rich blood.

Adopt­ing a healthy diet is con­sid­ered a key fac­tor in re­duc­ing the risk of heart at­tack, and many stud­ies have sug­gested that in­clud­ing omega-3 polyun­sat­u­rated fatty acids as part of such a diet is par­tic­u­larly ben­e­fi­cial for heart health.

Other stud­ies, how­ever, have ques­tioned the heart ben­e­fits of omega3s, with some sug­gest­ing that fish oil sup­ple­ments - a ma­jor source of the fatty acids - do not lower the risk of heart-re­lated events.

Omega-3s are es­sen­tial fatty acids that the body needs for cer­tain functions, in­clud­ing blood clot­ting, di­ges­tion, mus­cle ac­tiv­ity, and cell di­vi­sion and growth. How­ever, the only way the body can get omega3 is through the foods we eat.

Fatty fish - such as salmon, trout, tuna, sar­dines, and an­chovies - is a key source of omega-3s, in­clud­ing eicos­apen­taenoic acid (EPA) and do­cosa­hex­aenoic acid (DHA). Other sources in­clude leafy veg­eta­bles, wal­nuts, and some veg­etable oils, which nor­mally con­tain the omega-3 al­phali­nolenic acid (ALA).

For this lat­est study, lead re­searcher Liana C. Del Gobbo, Ph.D., of the Di­vi­sion of Car­dio­vas­cu­lar Medicine at Stan­ford Univer­sity School of Medicine in Cal­i­for­nia, and col­leagues set out to gain a bet­ter un­der­stand­ing of how omega-3s af­fect heart health.

Specif­i­cally, they looked at how omega-3s de­rived from seafood- and plant-based foods in­flu­ence the risk of death from heart at­tack, or my­ocar­dial in­farc­tion.

Risk of fa­tal heart at­tack 10 per­cent lower with higher omega-3 lev­els The team an­a­lyzed the data of 19 stud­ies that in­cluded 45,637 in­di­vid­u­als from across 16 coun­tries, in­clud­ing the U.S., the United Kingdom, Italy, Nor­way, and Aus­tralia.

Over time, 7,973 of the par­tic­i­pants ex­pe­ri­enced a first-time heart at­tack, with 2,781 dy­ing as a re­sult. The team found that par­tic­i­pants who had higher con­cen­tra­tions of seafood- and plant-based omega-3s in their blood were around 10 per­cent less likely to die from heart at­tack, com­pared with par­tic­i­pants who had lower omega3 con­cen­tra­tions.

How­ever, the re­searchers iden­ti­fied no re­duced risk of non-fa­tal heart at­tack with higher blood lev­els of seafood- and plant-based omega-3s, which they say in­di­cates there is a highly spe­cific mech­a­nism by which the fatty acids lower heart at­tack death risk. KARACHI—PPP chair­man Bi­lawal Bhutto, ac­com­pa­nied by pro­vin­cial home min­is­ter An­war Sial vis­ited the house of slain sufi mu­sic singer Am­jad Sabri, sym­pa­thized with his mother, and other fam­ily mem­bers and as­sured them that killer of the late qawwal will be ar­rested.

Strict security mea­sures were ap­plied as Bi­lawal moved to Li­aquatabad area in caran­van. All streets and shops were sealed off and closed for the time he was there. He ex­pressed deep­est sym­pa­thies with the mother of the slain celebrity, as­sur­ing her that killer will soon be ar­rested.

As he came out of the house, jour­nal­ists fired a salvo—what was the progress in Owais Shah kid­nap­ping and as­sas­si­na­tion of Am­jad Sabri? The ques­tion was di­rect, but Bi­lawal ducked, putting the home min­is­ter in front.

“Re­ply them now, Sindh gov­ern­ment, re­ply now” he was blunt, forc­ing many an an­a­lyst to in­ter­pret this as his an­noy­ance with the per­for­mance of the PPP gov­ern­ment in Sindh.

In re­lated event, MQM deputy con­vener Dr Fa­rooq Sat­tar called on Sindh chief jus­tice, Sa­j­jad Ali Shah to en­quired about the wel­fare of his kid­napped son. He later said that dis­tances were widen­ing be­tween peo­ple and the gov­ern­ment.

The Sindh gov­ern­ment had failed to come up to peo­ples ex­pec­ta­tions.

He said the kid­nap­ping showed that every­thing was not well in Sindh or Karachi. He as­sured the chief jus­tice of MQM’s fullest co­op­er­a­tion, and de­manded that Owais Shah be re­cov­ered soon.
