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