Drinking Coffee Regularly Decreases DNA Damage

- Adam Clare

I start my day with coffee and writing a post about good news. Today those two things merged rather well: it turns out drinking coffee regularly can lower the chances that one’s DNA will get messed up.

DNA is always doing bizarre things and if those things get too bizarre then it can cause some very bad mutations. For some reason coffee keeps your DNA doing the right thing.

As one commentator on Reddit said:

Their findings indicate that those who drank 750 ml (~3 cups) of coffee per day experienced 27% fewer strand breaks in white blood cells than those who only drank water, controlling for diet and body weight.

Here’s the paper’s abstract:

Abstract
PURPOSE:
Coffee consumption has been reported to decrease oxidative damage in peripheral white blood cells (WBC). However, effects on the level of spontaneous DNA strand breaks, a well established marker of health risk, have not been specifically reported yet. We analyzed the impact of consuming a dark roast coffee blend on the level of spontaneous DNA strand breaks.

METHODS:
Healthy men (n = 84) were randomized to consume daily for 4 weeks either 750 ml of fresh coffee brew or 750 ml of water, subsequent to a run in washout phase of 4 weeks. The study coffee was a blend providing high amounts of both caffeoylquinic acids (10.18 ± 0.33 mg/g) and the roast product N-methylpyridinium (1.10 ± 0.05 mg/g). Before and after the coffee/water consumption phase, spontaneous strand breaks were determined by comet assay.

RESULTS:
At baseline, both groups exhibited a similar level of spontaneous DNA strand breaks. In the intervention phase, spontaneous DNA strand breaks slightly increased in the control (water only) group whereas they significantly decreased in the coffee group, leading to a 27 % difference within both arms (p = 0.0002). Food frequency questionnaires indicated no differences in the overall diet between groups, and mean body weight during the intervention phases remained stable. The consumption of the study coffee substantially lowered the level of spontaneous DNA strand breaks in WBC.

CONCLUSION:
We conclude that regular coffee consumption contributes to DNA integrity.

Seville is Spain’s Cycling Gem

- Adam Clare 1 Comment

It’s well known that the future of urban design and transportation will support the mass use of bicycles. Still, some cities are slow to catch on to this. In Spain where cycling is not nearly as popular in colder northern parts of Europe the city of Seville is leading the charge into the future.

How Seville became such a great cycling city is a far out tale:

“As soon as the building work was finishing and the fences were removed the cyclists just came. The head of the building team, who’d been very sceptical about the process, called me and said, ‘Where have all those cyclists come from?’ That’s when I knew for sure it was going to work. The came from all over the city.”
…
The net result is not Dutch or Danish levels of cycling, but nonetheless impressive. The average number of bikes used daily in the city rose from just over 6,000 to more than 70,000. The last audit, about a year ago, found 6% of all trips were made by bike, rising to 9% for non-commuter journeys.

Discard These 20 Things to Improve Your Health

- Adam Clare

There are some minor things you can do around your home to improve your health and the health of the planet. These things range from where you plant trees and what you buy, Time magazine has looked in the opposite direction: what to throw away. They have a list of 20 things that (if you’re buying) you should discard.

Your stash of diet soda

If you haven’t already, you may want to reconsider your diet soda habit—especially if you’re trying to lose weight. A much-buzzed-about study published in the journal Nature found that non-caloric sweeteners such as saccharin (Sweet-n-Low), sucralose (Splenda), and aspartame (Equal) may mess with the gut bacteria that play a key role in healthy metabolism. Researchers found a link between these sweeteners, altered gut microbes, glucose intolerance and metabolic syndrome (both precursors to Type 2 diabetes) in mice and humans.

Amplifyd: A Platform to Stop Corporations from Doing Evil

- Adam Clare

Amplifyd Pledges – How It Works from Amplifyd on Vimeo.

Amplifyd is a new online platform that connects people to empower campaigns that want to stop corporations from doing evil things. The first campaign is focused on getting Starbucks and Peet’s Coffee to serve only organic milk in their stores.

In the future you can use the service in other ways. Is a company tearing down the rainforest or destroying land for precious minerals? Well you can use Amplifyd to get attention on the bad company!

Not all corporations are as overtly dreadful, but regardless, profits rule the day for most corporate organizations.

Amplifyd has launched a new advocacy platform, called Amplifyd Pledges, that gives people the power to take an amplified stand against harmful corporate policies, without even having to get up.

People can take part and amplify their voice by making a pledge to a campaign on the new platform. This works by choosing a dollar amount, then securely saving your credit card info for later. Amplifyd uses the collective pledges everyone makes as the financial carrot to get the corporations to change their policies.

The 20 Safest Cities in the World

- Adam Clare 1 Comment

The Economist safe cities list (pdf link) has been released and the results are pretty neat! There are some cities that you’d expect to be there and some surprise too!

The analysts looked at digital, health, and personal security of every city on the list plus the condition of the city’s infrastructure.

Is you city on the list?

3. Osaka

The Japanese city of 2.6 million ranks second in personal safety and sixth in health security. As with Tokyo, Osaka is relatively wealthy, and it ranks second for GDP per capita among upper-middle-income cities.
The city ranks lower in digital security than Tokyo, as it has fewer cybersecurity teams and privacy policies.
