/oss/taxonomy/term/6296/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/medical-critical-thinking-student-contributors/oil-pulling-just-clutching-straws <p>Maintaining good oral hygiene is critical in order to maintain overall health. Many people only realize the impact that dental health has on the rest of the body when they are reading the posters in the dentist’s waiting room. Typically, we are all very concerned with the whiteness of our smile and the smell of our breath and will strive to achieve oral perfection.</p> Fri, 24 Jan 2025 21:50:41 +0000 Angelina Lapalme 10237 at /oss /oss/article/medical-critical-thinking/case-drug-mule-who-went-undetected-abdominal-x-ray <p>Human drug couriers, colloquially known as “drug mules,” are people who smuggle drugs across a national border by hiding the drugs in the lining of their luggage, in clothes, by strapping the goods onto their bodies, or even by using their bodies as containers. The latter category of drug mules have been the focus of much media attention, and have been the subjects of numerous movies and television shows.</p> Thu, 16 Jan 2025 19:47:29 +0000 Melody Ko MD 10231 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/medical-critical-thinking/we-can-survive-without-food-about-70-days-only-5-days-without-water <hr /> <p><em>This article was first published in <a href="https://www.montrealgazette.com/opinion/columnists/article657433.html">The Montreal Gazette.</a></em></p> Fri, 10 Jan 2025 20:26:58 +0000 Joe Schwarcz PhD 10227 at /oss /oss/article/medical-critical-thinking-pseudoscience/quantum-university-misuses-physics-train-fake-doctors <p>The current member of the Legislative Assembly for the British Columbia electoral district of Langley-Willowbrook is Ms. Jody Toor.

Everything is fine until someone in the "Crooked House" switches the eyedrops with the insulin.

His ideas about vaccination, raw milk, hyperbaric oxygen, HIV, Wi-Fi and COVID fly in the face of evidence-based science. But once in a while, even a blind squirrel finds an acorn, so not all of Kennedy’s ideas are outrageous.

Indeed, more than a hundred-twenty, or over one-quarter of all drugs that currently exist, are derived from plants, although many of these have been chemically modified from their original form so as to improve potency and/or reduce unwanted side effects.</p> Fri, 22 Nov 2024 16:02:03 +0000 Patricia Brubaker, Ph.D., F.R.S.C. 10173 at /oss
