Hypothyroidism: The facts, the controversies, and the pseudoscience
As glands go, we don’t give the butterfly-shaped thyroid that straddles our trachea too much thought — until it stops working properly. The thyroid is a bit like your home’s thermostat: turn it high, and you’re hyperthyroid: heat intolerant, a high heart rate, and maybe some diarrhea. Turn it down, and you’re hypothyroid: cold, tired, constipated, and possibly even depressed. Both conditions...
Vitamin B12 – The Energy Panacea?
Having spent many hours working in close proximity to a wall of vitamins, I’ve answered a lot of vitamin questions, and given a lot of recommendations. Before I can make a recommendation, I need to ask some questions of my own. My first is almost always, “Why do you want to take a vitamin?” The most common response I’m given is “insurance”...
Eat Fat, Get Thin?
I recently received an e-mail from a high school science department head who is teaching a unit on nutritional science. He asked for my opinion of a YouTube video of a lecture advocating a high saturated fat diet. The speaker is Donald W. Miller, Jr., M.D., a cardiothoracic surgeon at my alma mater, the University of Washington. My correspondent commented, “I have...
Collagen: An implausible supplement for joint pain
I’m one of those odd people that enjoys distance running. I end up spending a lot of time in the company of other runners. And when we’re not running, we’re usually griping about our running injuries. As the cohort that I run with ages, the injuries are getting more prevalent. Besides the acute conditions, the chronic problems are starting to appear. Our...
Steven Fowkes (Part 2 of 2): Nutrients for Better Mental Performance
Last week, in part 1, I covered Steven Fowkes’ “cures” for Alzheimer’s and herpes. In part 2, I will cover a video where he goes further afield. It is titled “Nutrients for Better Mental Performance,” but he also discusses sleep, depression, hangovers, and a lot of other topics. Some of what he says are simple truisms: mental performance is affected by everything...
“And one more thing” about Steve Jobs’ battle with cancer
Did Steve Jobs' delay in undergoing surgery for his cancer cost him his life? The new Walter Isaacson biography provides more information, but does not resolve the question.
Steve Jobs’ medical reality distortion field
As I pointed out in my previous post about Steve Jobs, I’m a bit of an Apple fan boy. A housemate of mine got the very first Mac way back in 1984, and ever since I bought my first computer that was mine and mine alone back in 1991 (a Mac LC), I’ve used nothing but Macintosh computers, except when compelled to...
Vitamins and Mortality
The discovery of various vitamins – essential micronutrients that cause disease when deficient – was one of the great advances of modern scientific medicine. This knowledge also led to several highly successful public health campaigns, such as vitamin-D supplementation to prevent rickets. Today vitamins have a deserved reputation for being an important part of overall health. However, their reputation has gone beyond...
Steve Jobs’ cancer and pushing the limits of science-based medicine
Editor’s note: There is an update to this post. An Apple fanboy contemplates computers and mortality I’m a bit of an Apple fanboy and admit it freely. My history with Apple products goes way back to the early 1980s, when one of my housemates at college had an Apple IIe, which I would sometimes use for writing, gaming, and various other applications....
Artificial Sweeteners: Is Aspartame Safe?
Note: This was originally published as a “SkepDoc” column in Skeptic magazine under the title “Aspartame: Safe Sweetener or Perilous Poison?” and is reprinted here with the kind permission of Michael Shermer. There are other artificial sweeteners not specifically addressed here, but as far as I know there are no convincing health concerns about any of them, just this same kind of...
