A new study published in JAMA Internal Medicine on the health
effects of resveratrol – a compound found in red wine, dark chocolate
and some fruits and vegetables – has generated a lot of sensational
headlines.
“New study reports no health benefits from red wine and chocolate,” one headline proclaims. “Red wine and dark chocolate won’t save your life,” another declared.
In my opinion, these headlines aren’t accurate and may be confusing to the reader.
Here are the facts: Researchers from Johns Hopkins University collected data from 783 Italians, who were all at least 65 years old, starting in 1998. Over the course of the nine-year study, each participant completed a dietary survey every three years and gave a urine sample just once at the beginning of the study to
measure the levels of dietary resveratrol in their urine. At the end of the study, the researchers found there were no differences in rates of death, heart disease, cancer or inflammation levels among people who had the highest levels of resveratrol at the onset of the study
compared to those who had the lowest levels. Now, there were many factors omitted in the study. We have limited knowledge of the lifestyle and family histories of these participants. Furthermore, surveys carry a certain degree of inaccuracy, because they rely on the honor system. And the researchers did not measure participants’ resveratrol levels at the end of the nine-year study period to see how these levels might have changed. They simply assumed participants’ diets remained the same, after the surveys indicated as much. read more:- http://www.foxnews.com/health/2014/05/13/dr-manny-why-new-study-on-resveratrol-isnt-really-bad-news-for-red-wine/
