As if we needed another reason to love chocolate: Researchers who studied 20 patients with peripheral artery disease found that the polyphenols in cocoa could increase blood flow, thus improving vascular health.
Peripheral artery disease (PAD) affects 20 percent of adults 70 and older in the U.S. and other Western countries, and makes it difficult for people to exercise and walk because of impaired blood flow. For this study, published in the Journal of the American Heart Association, researchers gave half of the participants 1.5 ounces of dark chocolate with at least 85 percent cocoa, and gave the other half 1.5 ounces of milk chocolate with less than 30 percent cocoa. The goal was to see if dark chocolate made it easier for patients to walk on a treadmill.
"After eating the dark chocolate, [the participants] walked an average 11 percent farther," study author Lorenzo Loffredo of Rome's Sapienza University told NPR's The Salt blog. An improvement in blood flow was seen in these patients, but "conversely, we did not observe effects on blood flow and on walking autonomy in PAD patients after milk chocolate consumption."
Researchers said the polyphenols in dark chocolate — which are already known to help fight inflammation — are able to reduce oxidative stress and help the body form more nitric oxide, which causes blood vessels to dilate.
Don't run down to the nearest grocery store and stock up on dark chocolate just yet. Dr. Mark Creager of Brigham and Women's Hospital said that the "overall effect [of the dark chocolate] was relatively modest," and the 11 percent increase in walking only adds up to 40 more feet. "To put this in context, with other forms of treatment, such as supervised exercise training, maximal walking distance increases by approximately 100 percent." Catherine Garcia
Sen. Marco Rubio (R-Fla.) maintained Friday that he'll support the Republican presidential nominee, even if that somebody happens to be Donald Trump, The Palm Beach Post reports.
In fact, Rubio might be more impressed with the billionaire business mogul than usual, saying his "performance has improved significantly" recently.
Republican presidential frontrunner Donald Trump was none too thrilled Saturday with the protesters who blocked his way into California's Republican convention the day before:
The "protesters" in California were thugs and criminals. Many are professionals. They should be dealt with strongly by law enforcement!

Leave it to Trump to make an off-color joke about the incident once he made it inside the hotel Friday.
Jimmy Fallon has been singing bits and pieces of Styx's "Too Much Time on My Hands" on The Tonight Show for days. On Friday, he and actor Paul Rudd took the obsession to its natural conclusion, creating a shot-by-shot remake of the '80s music video. The end result is sufficiently goofy. Take a look below.

Hundreds of activists stormed Iraq's parliament building Saturday in support of Shiite cleric Muqtada al-Sadr, who had accused Iraqi politicians of corruption, CBS News reports.
The demonstrators climbed over blast walls in Baghdad's Green Zone, which houses most of the country's ministries and foreign embassies, after parliament couldn't reach quorum to hold a session. The protesters broke furniture, chanted, and waved Iraqi flags.
San Francisco Police Chief Gregory Suhr released nine pages of racist and homophobic text messages sent between officers Friday and ordered all officers to undergo anti-bias training, The New York Times reports.
"We have nothing to hide," Suhr said of his 2,000-member force. "These are the actions of a few."
The messages, which disparaged blacks, Latinos, South Asians, and LGBT people, were found as part of an investigation into a rape charge against one of the officers.
The head of an evangelical legal organization has pledged to carry a gun into Target's bathrooms to defend against transgender women. Liberty Counsel President Anita Staver is calling for a boycott of the retail chain after it announced that it will allow patrons to use the restroom that corresponds to their gender identity, The Huffington Post reports.
