But vitamin D and fish oil did not reduce the risk of attack or cancer in themselves.
The study showed that the heart rate of those who eat fish oil was 28 percent lower than those who took fake drugs and reduced the risk of 77 percent in African Americans. But the lead author of the study told Reuters about health, it needs to be confirmed a lot.
"The cancer mortality rate among those taking vitamin D was 25 percent lower," said Dr. Joan Manson, head of preventive medicine at Brigham & Venom hospital in Boston, adding that this may be because vitamin "can affect the vital structure of the tumor , Reducing the likelihood of spreading to other areas of the body. "
"We may see a reduction in mortality from cancer, but this is not a reduction in initial diagnosis. A longer study is needed … If we talk about cancer prevention, it can happen more than a decade," she said in a telephone interview.
A new study was published online at Nev England Journal of Medicine. Most of the previous studies focused on volunteers who are already at high risk of heart attack, stroke or cancer.
The study included 25,871 participants aged 50 and no one had a heart attack, stroke or cancer earlier. More than half of them were followed by more than five years of study.
Manson said that new findings would make "those who eat vitamin D or fish oil already feel that they will not stop them."
However, some might want to wait for more results to be reported on the relationship of these diabetes supplements, cognitive function, depression, and autoimmune diseases in the next six months to determine whether the benefits are useful for addressing, she said.
