Increasing time spent doing high-impact physical activity as a youth is a simple and direct way to improve skeletal health. One of the programming directives offered at the CrossFit Kids Certificate Course is including impact-loading exercises on a daily basis. This simple addition results in meaningful and significant benefits not only in terms of the improved fitness it generates through these plyometric exercises but also with respect to increased skeletal health in the long term.

"For years, experts have recommended low-fat dairy products over the full-fat versions, which are higher in calories and contain more saturated fat. Recent research, however, indicates that full-fat dairy may actually be healthier than its reputation suggests, and that people who eat full-fat dairy are not more likely to develop cardiovascular disease and type 2 diabetes than people who consume low-fat dairy. They may even be less likely to gain weight."

The Song of Wandering Aengus,” by William Butler Yeats

Dr. Maryanne Demasi worked as a journalist and producer for the Australian Broadcasting Corporation (ABC) for 11 years. In 2013, she produced a two-part series called “Heart of the Matter,” which challenged the role of cholesterol in heart disease and addressed the overprescription of statin drugs. The series received excellent ratings and was praised by ABC management for being “superbly presented” and “provocative.” Over time, however, reception became less favorable. Demasi attributes the shift to the media storm stirred by those with vested interests in statins. Here, she shares her story and explains why the fallout is indicative of a “crisis of democracy” in the sciences.

The Modified Rope Climb

Dr. Malcolm Kendrick discusses recent concerns in the medical community regarding the potential for bias in clinical research on statin therapy. He reviews the various reasons statin trials may be unreliable, including selective publication of results and strategic shifting of trial endpoints during ongoing studies. Despite the apparent evidence-based support of statin therapy and measures taken in the 1990s and early 2000s to mitigate bias, Kendrick urges doctors to proceed with caution when recommending the drugs. Echoing another review from 2015, Kendrick claims “a complete reassessment [of their efficacy and safety] is mandatory.”

"Heartburn, ulcer and acid reflux medicine may bring relief, but over time, they could also increase a person's risk of early death, new findings show. Researchers have linked popular drugs like Prevacid, Prilosec, Nexium, Protonix and other proton pump inhibitors to a higher risk of death by cardiovascular and chronic kidney disease, as well as upper gastrointestinal cancer, according to a study published in The BMJ. More than 15 million people are prescribed PPIs each year, while millions more purchase them over-the-counter, the researchers say."

The AbMat Sit-Up

Scientists continue to discover evidence of the therapeutic value of nutritional ketosis for a range of conditions, including Type 2 diabetes, Alzheimer’s, and cancer. Dr. Dominic D’Agostino, an Associate Professor of Molecular Pharmacology and Physiology at the University of South Florida, is at the forefront of research related to the use of ketosis for cancer treatment. During a presentation on July 31, 2019, at the annual CrossFit Health Conference in Madison, Wisconsin, D’Agostino shared his knowledge of the health benefits associated with ketones and presented his latest research on ketosis as an adjuvant treatment for high-grade glioma.
