When it’s easier for bubbles to form, you get more of them and therefore an increased “fizziness”.</p> Fri, 16 Sep 2022 10:00:00 +0000 Ada McVean B.Sc. 9223 at /oss /oss/article/health-nutrition/lets-tax-sugary-drinks-discourage-consumption <hr /> <p>This article was first published in <a href="https://montrealgazette.com/opinion/columnists/christopher-labos-lets-tax-sugary-drinks-to-discourage-consumption?fbclid=IwAR39yQHeK56tp4RdHuRnTtJvmHSiHB8EoHFyFI_dKUJxz5cXpdoDpFAVHj8">The Montreal Gazette.</a></p> <hr /> <p>One way to get people to reduce their consumption of sugary drinks is a soda tax. In fact, the World Health Organization has recommended just that. While New York tried to bring in such a tax and failed, cities like Berkeley and Philadelphia made it happen in 2015 and 2017.</p> Fri, 26 Jul 2019 15:57:12 +0000 Christopher Labos MD, MSc 7839 at /oss /oss/article/general-science-history/god-glycerine-flavouring-and-kosher-coca-cola <hr /> <p><em>​This article was first published in <a href="http://montrealgazette.com/opinion/columnists/the-right-chemistry-god-glycerine-flavouring-and-kosher-coca-cola">The Montreal Gazette</a>.</em></p> Tue, 27 Mar 2018 16:09:49 +0000 Joe Schwarcz PhD 6975 at /oss /oss/article/controversial-science-quirky-science/letting-fizz-out-fizz-keeper <p>A little pump called the “Fizz Keeper” is available in kitchen supply stores to pressurize previously opened soft drink bottles and prevent loss of carbonation. The idea appears to make sense, but actually, the device does not work. Pumping the bottle can restore the pressure above the solution so the bottle feels hard, just like when it was purchased. But the manufacturers are unaware of Henry’s Law.</p> Sat, 04 Jan 2014 20:28:55 +0000 Joe Schwarcz PhD 2060 at /oss /oss/article/health-you-asked/depression-and-soft-drinks <p>There’s some bitter news about sweet pop! But you have to take it with a grain of salt. Beginning in 1995, researchers from the National Institute of Environmental Health in the U.S. had more than 250,000 adults between the ages of 50 to 71 fill out questionnaires about the kinds of drinks they consumed.Ten years later they asked the participants whether they had been diagnosed with depression since the year 2000. The participants reported a total of 11,311 depression diagnoses.</p> Wed, 16 Jan 2013 18:13:26 +0000 OSS 1857 at /oss /oss/article/food/natural-soft-drinks <p>The money that carbonated soft drink companies spend on advertising is astounding. Coca Cola dishes out about 235 million dollars a year to push its flagship product. But as far as producers are concerned, advertising dollars are well spent, the global soft drink market is worth about 75 billion dollars a year! Colas are the most popular drinks, with lemon-lime flavoured beverages ranking a distant second, accounting only for about 10% of sales. Of course that is still a hefty amount, but companies are concerned because sales of these drinks have been dropping.</p> Tue, 07 Feb 2012 17:24:35 +0000 Joe Schwarcz 1631 at /oss
