Red wine and chocolate might be the perfect combination for recharging after a long day, but a new study suggests they’re not the magical elixir for a longer life.
Researchers at Johns Hopkins University found that resveratrol — the antioxidant in red wine and chocolate that has long been cited as a possible explanation for the “French Paradox” — actually has little effect on aging.
Researchers tracked for 11 years roughly 800 Italian men and women age 65 and older to determine if the levels of resveratrol in their diet played a role in reducing inflammation, cancer, cardiovascular disease, and death. They found no association between resveratrol and longevity of life.
Richard Semba, a professor at Johns Hopkins and the lead researcher on the project, said it oversimplifies the “French Paradox” to credit resveratrol intake through heavy wine consumption as the reason the French have low rates of cardiovascular disease despite a diet rich in fatty foods.
“I think there are other factors involved,” Semba said. “Other antioxidants other than resveratrol could contribute, “¦ or smaller portions and more exercise. The ‘French Paradox’ is still kind of a hypothesis. It doesn’t seem to make sense.”
The National Institute on Aging funded the research, which was conducted independently of the agency.
The research doesn’t overturn the so-called French Paradox altogether — other chemical compounds in red wine and chocolate could still offer health benefits, Semba says. And resveratrol has been linked in earlier tests of nonhuman species such as mice to anti-aging benefits, reduced risk of blood clotting, and prevention against obesity and diabetes.
But the findings from Johns Hopkins are based on the first studies using human subjects to determine the effects of resveratrol on aging, according to Semba.
So when it comes to buying resveratrol in dietary supplements, he doesn’t recommend shelling out the dough. Semba calls the supplements a “false hope” — about as effective as drinking large quantities of red wine to improve your health.

President Obama commuted the sentences of another 98 drug offenders on Thursday. Most of the convicts were charged with conspiracy to distribute drugs or possession with intent to distribute. Many of the sentences were commuted to expire next year, but some will run longer. Others are required to enroll in residential drug treatment as a condition of their release.
The Department of Justice announced today it's charged "61 individuals and entities for their alleged involvement in a transnational criminal organization that has victimized tens of thousands of persons in the United States through fraudulent schemes that have resulted in hundreds of millions of dollars in losses. In connection with the scheme, 20 individuals were arrested today in the United States and 32 individuals and five call centers in India were charged for their alleged involvement. An additional U.S.-based defendant is currently in the custody of immigration authorities."
Evan McMullin, the independent conservative candidate who may win his home state of Utah, is quietly planning to turn his candidacy into a broader movement for principled conservatism. He tells BuzzFeed he's "skeptical" that the Republican party can reform itself "within a generation" and that the party's internal "disease" can't be cured via "the existing infrastructure.” The ex-CIA employee and Capitol Hill staffer says, “I have seen and worked with a lot of very courageous people in my time [but] I have seen a remarkable display of cowardice over the last couple of months in our leaders.” McMullin's team has assembled organizations in the 11 states where he's on the ballot, and adviser Rick Wilson says "there’s actually a very vibrant market for our message in the urban northeast and in parts of the south."
