Health benefits of wine and chocolate unlikely, new study finds – May 13, 2014 Globe and Mail

I enjoyed reading a May 13, 2014 Reuters news report, published in The Globe and Mail, and hearing CBC radio reports about recent research findings related to wine and chocolate.

The opening paragraphs of the Reuters article read:

  • A compound found in wine and chocolate may not be linked to improved health as was once claimed, according to a new study.
  • The compound resveratrol was not associated with less inflammation, cardiovascular disease or cancer or with increased longevity among a group of elderly Italians, researchers found.

“The French Paradox”

A May 12, 2014 CBC article is entitled: “Red wine antioxidants don’t improve heart health: Health benefits of red wine don’t pan out.”

The opening paragraphs read:

  • You might not be able to pass off the daily glass of red-wine as good for your heart anymore.
  • After years of believing the “The French Paradox,” – the high cholesterol diet but low heart disease phenomenon in the French that was attributed to red wine intake, a study released at John’s Hopkins University in Baltimore today showed no correlation between red wine and the incidence of heart disease, cancer and inflammation.

The power of habit

I’ve enjoyed having a glass of red wine – such as Trius Cabernet Sauvignon with the twist-off cap – on alternating days for many years. I’ve also enjoyed eating dark chocolate, such as Camino Fair Trade Organic 70% cacao dark chocolate.

As regular habits, it’s something that I’ll be able to look back on fondly. Coffee – brewed at home from freshly roasted, freshly ground coffee beans – along with green tea, will remain among my favourite sources of diversion.

Getting sugar consumption below 25 grams per day hasn’t been a struggle, in my case, now that I’m aware of the research. Increasing the quantity of vegetables has seen some progress. Fish oil supplements I stopped taking years ago, as the research accumulated. The exercise part of the equation I’ve always been pretty good at. I also ensure I don’t spend all day sitting.

Evidence

What accounts for my interest in evidence-based practice? Different people come across a data-oriented approach to life for different reasons. Some never develop an interest in data and pursue truthiness instead. In my case, I spent many years looking for a way to deal with the fact that I stuttered. I finally found a speech therapy program – at a three-week speech clinic in Edmonton in 1987 – that worked for me. In the process, I learned of the value of scientific data, and of research reports published in peer-reviewed professional journals. Unless there’s solid, published evidence, I’m not interested.

Other people approach their particular challenges, if they have them, in their own way, whatever that way might be.

I mention this story because it accounts for my focus on the relevance and salience of evidence. I doubt I would have become interested in “looking at the data” had I not had the experiences, in the late 1980s, that I have described.

Updates: Chocolate and memory, and the origins of the enjoyment of alcohol

An Oct. 16, 2014 New York Times article is entitled: “To Improve a Memory, Consider Chocolate.”

The opening paragraphs read:

  • Science edged closer on Sunday to showing that an antioxidant in chocolate appears to improve some memory skills that people lose with age.
  • In a small study in the journal Nature Neuroscience, healthy people, ages 50 to 69, who drank a mixture high in antioxidants called cocoa flavanols for three months performed better on a memory test than people who drank a low-flavanol mixture.
  • On average, the improvement of high-flavanol drinkers meant they performed like people two to three decades younger on the study’s memory task, said Dr. Scott A. Small, a neurologist at Columbia University Medical Center and the study’s senior author. They performed about 25 percent better than the low-flavanol group.

 A Dec. 13, 2013 CBC article is entitled: “Human taste for alcohol linked to apes eating rotten fruit: Apes eating fermented fruit led to our taste for alcohol, says Matthew Carrigan.”

The Importance of an Occupation after Retirement!

Update regarding above-noted New York Times article. That’s the one that says: “To improve a memory, consider chocolate.”

A Jan. 5, 2015 CBC article is entitled: “Chocolate health myth dissolves: Health-enhancing flavanols that end up on the shelf will likely appear in form other than chocolate.”

The opening paragraphs read:

“When the New York Times ran this headline last fall, “To improve a memory, consider chocolate,” it quickly became one of the newspaper’s “most emailed” stories. Other news outlets rushed to match the story.

“My assignment desk perked up and sent me the clipping with the question ‘interesting?’ And it was interesting, but not for the reasons most news editors hope.

“It was interesting because the study was not about chocolate at all. That’s because chocolate contains almost none of the compound that the researchers are studying.

“It’s an irony that lies at the heart of a major international scientific effort to find something healthy in the cocoa bean, an effort largely sponsored by the chocolate industry.”

Another CBC article on same topic (that is, checking the facts behind health claims related to chocolate)

Another Jan. 5, 2015 CBC article is entitled: “Chocolate’s health touters ‘may have misunderstood local reality’ of tribe: How much cocoa do Kuna really consume?”

An excerpt reads:

“Because his observations of Kuna cocoa consumption were so starkly different, Barnes thought he had missed something and went back to Panama, to the same island where the Mars research was done, for a closer look.

“I looked into how much locally grown cacao people were actually consuming and the results were quite outstanding,” Barnes said. ‘It would appear as though they are not consuming much at all.’

“‘Recent studies may have misunderstood the local reality in their depictions of the Kuna people of Ailigandi as prolific consumers of locally derived cacao,’ he concluded in a paper published in 2013 in Human Organization, the peer reviewed journal of the Society for Applied Anthropology.

“The response to his myth-busting findings? Complete silence.

“‘The media is always plastered with news about how healthy chocolate is for you,” he said. “I was dismayed to find that no one picked it up.'”
