/oss/taxonomy/term/337/all en /oss/article/medical-health-and-nutrition/confronting-bulimia <p>Bulimia nervosa, or more commonly known as bulimia, is an eating and psychiatric disorder characterized by binge eating followed by intentional purging. The latter is usually done in order to compensate for the excessive intake of food and to prevent weight gain. Purging can take the form of vomiting, inappropriate use of laxatives, enemas, diuretics or other medication; or excessive physical exercise. This disease was first described by Dr. Gerald Russel in 1977 when he was working at the Royal Free Hospital in London.</p> Wed, 29 Jan 2025 19:02:54 +0000 Melody Ko MD 10240 at /oss /oss/article/critical-thinking-health-and-nutrition/red-dye-3-isnt-felon-lurking-food-supply <hr /> <p><em>This article was first published in <a href="https://www.montrealgazette.com/opinion/columnists/article690801.html">The Montreal Gazette.</a></em></p> <hr /> <p>In the late 19th century, Germany was at the forefront of chemical research and it was an ideal place for Purdue University chemistry professor Dr. Harvey Washington Wiley to spend a sabbatical to broaden his horizons.</p> Fri, 24 Jan 2025 22:13:58 +0000 Joe Schwarcz PhD 10238 at /oss /oss/article/critical-thinking-health-and-nutrition/benefits-backward-walking-are-not-solid-ground <p>According to <u><a href="https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fweb.archive.org%2Fweb%2F20241217121253%2Fhttps%3A%2Ftime.com%2F6975058%2Fbackward-walking-health-benefits%2F&data=05%7C02%7Chaleh.cohn%40mail.mcgill.ca%7C402414f0782d42d1230508dd3bd5425a%7Ccd31967152e74a68afa9fcf8f89f09ea%7C0%7C0%7C638732509326710509%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=s1d170iRSFJhJR1TrdE9E%2BVKrfb%2BGpygNLtOEX4wGPo%3D&reserved=0" rel="noopener noreferrer" target="_blank" ti=""></a></u></p> Fri, 24 Jan 2025 06:38:51 +0000 Jonathan Jarry M.Sc. 10234 at /oss /oss/article/health-and-nutrition-history-did-you-know/vitamins-are-vital-life <p>The term “food accessory factor” was coined by British biochemist Frederick Gowland Hopkins in 1906 after he demonstrated that rats fed a diet of proteins, fats, carbohydrates and minerals failed to grow. Although these substances were known to be the major components of the food supply, they were not sufficient to maintain health. Something was missing. When Hopkins supplemented the diet with minute amounts of milk, the rats thrived. There was something in the milk in addition to the usual nutrients, some “food accessory factor” that was necessary for growth. </p> Thu, 23 Jan 2025 13:00:00 +0000 Joe Schwarcz PhD 10233 at /oss /oss/article/medical-critical-thinking-health-and-nutrition/can-glass-milk-day-reduce-risk-colon-cancer <p>The dairy industry is smiling because a study published in the prestigious journal, Nature, concluded that “dairy products help protect against colorectal cancer, and that this is driven largely or wholly by the calcium they contain.” The study triggered headlines about how drinking a glass of milk a day can reduce the risk of colon cancer by 17%. That isn’t quite correct. It may be true for women who consume less than the recommended 1000 mg of calcium a day, but may not apply to those who already consume the recommended amount.</p> Wed, 15 Jan 2025 17:08:49 +0000 Joe Schwarcz PhD 10230 at /oss /oss/article/critical-thinking-health-and-nutrition/evidence-mounts-against-ultra-processed-foods <hr /> <p><em>This article was first published in <a href="https://www.montrealgazette.com/opinion/columnists/article647194.html">The Montreal Gazette.</a></em></p> Fri, 10 Jan 2025 19:13:55 +0000 Joe Schwarcz PhD 10225 at /oss /oss/article/critical-thinking-health-and-nutrition-pseudoscience/magnesium-necessary-nutrient-it-does-not-perform-miracles <p>The year was 1618, the place, Epsom, England. The farmer had just dug a well for his cows but the animals refused to drink the water. On tasting the water, he quickly discovered why. It was bitter! The water was undrinkable, but it would do for washing, he figured. That’s when he discovered that rubbing his body with the bitter water had a therapeutic effect. A skin rash disappeared, and his aching muscles stopped aching. When the water evaporated, it left behind some white crystals.</p> Thu, 09 Jan 2025 01:10:31 +0000 Joe Schwarcz PhD 10221 at /oss /oss/article/health-and-nutrition-did-you-know-general-science/lactose-free-milk <p>Ice cream, milk, cheese, yogurt, cream, butter and all other dairy products haunt the dreams of people with lactose intolerance. Over 68% of the world’s population has some degree of lactose malabsorption which is the inability to properly digest lactose, the sugar found in dairy products.

By shopping for fewer items and going for second-hand, I reduce waste, save money, and engage more with local businesses. A motivation for these shopping habits is reducing food waste, especially considering that according to the Food and Agriculture Organization of the United Nations the food that wasted globally could feed 1.26 billion people each year.</p> Fri, 13 Dec 2024 13:46:44 +0000 Paige Boklaschuk BSc 10196 at /oss /oss/article/critical-thinking-health-and-nutrition/are-black-plastic-spatulas-and-serving-spoons-safe-use <hr /> <p><em>This article was first published in <a href="https://montrealgazette.com/opinion/columnists/the-right-chemistry-are-black-plastic-spatulas-and-serving-spoons-safe-to-use">The Montreal Gazette.</a></em></p> <hr /> <p>There is probably no quote more often cited in discussions of toxicity than that of 16th-century Swiss physician and alchemist Paracelsus, namely that “only the dose makes the poison.”</p> Fri, 06 Dec 2024 18:28:36 +0000 Joe Schwarcz PhD 10192 at /oss /oss/article/health-and-nutrition-contributors-did-you-know/story-sushi <p>What is more romantic than an evening of sushi for two? Although this traditional Japanese dish has only become popular in the West relatively recently, the history of this culinary art with its unique zests and colourful presentation dates back to around 700 AD. It all started with a way to preserve fish! Raw, cleaned and salted fish was placed on a layer of hand-pressed rice that was allowed to ferment, meaning that naturally occurring microbes in the rice proceeded to convert some of the carbohydrates in the rice into lactic acid, an effective preservative.</p> Fri, 06 Dec 2024 05:51:01 +0000 Melody Ko MD 10190 at /oss
