Heavy Metal, Headbanging, and Our Health

Image
How might we moderate the rare but very real risk of headbanging? If you search for heavy metal in the National Library of Medicine database, most of what you find is on heavy metal contamination in fish, which “makes it difficult to establish clearly the role of fish consumption on a healthy diet” and perhaps helps to explain the quintupling of odds of autoimmune diseases, such as juvenile arthritis. But searching for the hazards of heavy metal also pops up entries on the “risks from heavy metal music.” In this study, researchers were talking about traumatic injuries from slamming around “during a moshing session,” but you’re more likely to get injured at an alternative rock concert. (Check out some of the artists below and at 0:50 in my video The Dangerous Effects of Heavy Metal Music .) Certainly, music-induced hearing loss is a serious problem, but that can result from any loud music. Clinical recommendations include the “80–90 rule”—no more than 80% of the maximum volum...

Prostate Cancer and Mushrooms

Image
What can reishi mushrooms, shiitake mushroom extracts, and whole, powdered white mushrooms do for cancer patients? “A regular intake of mushrooms can make us healthier, fitter, and happier, and help us live longer,” but what is the evidence for all that? “Mushrooms are widely cited for their medicinal qualities, yet very few human intervention studies have been done using contemporary guidelines.” There is a compound called lentinan, extracted from shiitake mushrooms. To get about an ounce, you have to distill around 400 pounds of shiitakes, about 2,000 cups of mushrooms. Researchers injected the compound into cancer patients to see what happens. The pooled response from a dozen small clinical trials found that the objective response rate was significantly improved when lentinan was added to chemotherapy regimens for lung cancer. “Objective response rate” means, for example, tumor shrinkage, but what we really care about is survival and quality of life. Does it actually make canc...

Cancer Survival and Medicinal Mushrooms

Image
Did the five randomized controlled trials of reishi mushrooms in cancer patients show benefits in terms of tumor response rate, survival time, or quality of life? Can mushrooms be medicinal? Mushroom-based products make up a sizable chunk of the $50 billion supplement market. “This profitable trade provides a powerful incentive for companies to test the credulity of their customers and unsupported assertions have come to define the medical mushroom business.” For example, companies marketing herbal medicines “exploit references to studies on mice in their promotion of mushroom capsules and throat sprays for treating all kinds of ailments”—but we aren’t mice. It wouldn’t be surprising if mushrooms had some potent properties. After all, fungi are where we’ve gotten a number of drugs, not the least of which is penicillin, as well as the cholesterol-lowering drug lovastatin and the powerful immunosuppressant drug cyclosporin. Still don’t think a little mushroom can have pharmacological ef...

Celebrating Native American Heritage Month with Chef Lois Ellen Frank, Ph.D.

Image
In honor of National American Heritage Month, we are thrilled to share Chef Lois Ellen Frank’s Navajo Minestrone Soup with you. For more about Chef Lois, check out this interview . “Navajo Nation President Jonathan Nez and First Lady Phefelia Nez have been vocal proponents of healthy eating. President Nez found that plant-based eating shortened his recovery time after long-distance runs and helps him to maintain his weight loss. First Lady Nez provided us with one of her family-favorite soup recipes that we modified. We used the modified version for a course called Native Food for Life Online, offered through the American Indian Institute (AII) and the Physicians Committee for Responsible Medicine (PCRM). Minestrone  is its Italian name, but the ingredients in this soup originated in the Americas. Chef Walter Whitewater said that growing up on the Navajo Nation, he used to harvest wild onions, carrots, garlic, and spinach. With the addition of frozen corn, canned beans, an...

Plant-Based Hospital Menus

Image
The American Medical Association passed a resolution encouraging hospitals to offer healthy plant-based food options. “Globally, 11 million deaths annually are attributable to dietary factors, placing poor diet ahead of any other risk factor for death in the world.” Given that diet is our leading killer, you’d think that nutrition education would be emphasized during medical school and training, but there is a deficiency. A systematic review found that, “despite the centrality of nutrition to a healthy lifestyle, graduating medical students are not supported through their education to provide high-quality, effective nutrition care to patients…” It could start in undergrad. What’s more important? Learning about humanity’s leading killer or organic chemistry? In medical school, students may average only 19 hours of nutrition out of thousands of hours of instruction, and they aren’t even being taught what’s most useful. How many cases of scurvy and beriberi, diseases of dietary de...

Celebrating Veterans Day with Ronnie Penn

Image
We had the pleasure of talking with Ronnie Penn about his military service, his work as a chef and a coach, and what Veterans Day means to him. We hope you enjoy this interview.    Thank you for your service, Ronnie. We’re honored to speak with you today. Can you start by sharing a bit about your background? What inspired you to enlist, and when did your military journey begin? I grew up wanting to serve something bigger than myself, and the Marine Corps gave me that opportunity. I enlisted in 2004 and deployed to Iraq during Operation Iraqi Freedom and to Afghanistan from 2012 to 2014. Later, I served in the Coast Guard as a chef, which opened a whole new chapter in how I looked deeper into nutrition. Service taught me discipline, resilience, and the importance of teamwork—qualities I carry into everything I do today.   How did your time in the military shape who you are today? Is there anything in particular about your service that you would like to share?...

Chlorohydrin 3-MCPD in Bragg’s Liquid Aminos

Image
Chlorohydrin contaminates hydrolyzed vegetable protein products and refined oils. In 1978, chlorohydrins were found in protein hydrolysates. What does that mean? Proteins can be broken down into amino acids using a chemical process called hydrolysis, and free amino acids (like glutamate) can have taste-enhancing qualities. That’s how inexpensive soy sauce and seasonings like Bragg’s Liquid Aminos are made. This process requires high heat, high pressure, and hydrochloric acid to break apart the protein. The problem is that when any residual fat is exposed to these conditions, it can form toxic compounds called chlorohydrins, which are toxic at least to mice and rats. Chlorohydrins like 3-MCPD are considered “a worldwide problem of food chemistry,” but no long-term clinical studies on people have been reported to date. The concern is about the detrimental effects on the kidneys and fertility. In fact, there was a time 3-MCPD was considered as a potential male contraceptive because i...
