Fish oil and heart diseases
The investigation does not mean that the fish oil is not of any value to the study does not address the question of whether he can help prevent heart disease, said the doctors in the first place.
Omega-3 are also in the fatty fish such as wild salmon, tuna, mackerel, sardines and herring, scientists believe that increases HDL or good cholesterol, reduces the triglycerides called harmful fats and slows the growth of the plate that can block the arteries.
The American Heart Association recommends that people eat fish at least twice a week, said Alice Lichtenstein, a professor of Tufts University nutrition and spokeswoman for the Association of the Heart.
For people with heart disease, the association advises 1 gram of omega-3 a day, and in a modest portion of 3 ounces of salmon is a bit more of a gram,” he said.
As regards the heart attacks, patients who are taking medicines to prevent problems in the future, not obtained an additional benefit to take capsules of fish oil, as evidenced a German study.
The study tested a gram 1-daily dose of the version of a recipe highly purified omega-3 fatty acids “fat good”, which is contained in some fatty fish that are believed to help the heart.
The researchers led by Dr. Jochen Senges of the Heidelberg University has given fish oil or capsules placebo to more than 3800 people who had suffered a heart attack in the previous two weeks.
About 90 percent had already received all the recommended medicines to prevent a second attack, including the aspirin, drugs anti-clotting and for cholesterol.
