Health Matters

Some links about health care matters.

  • A radical new hypothesis in medicine: give patients drugs they know don't work

    Why the placebo effect is weirder and potentially more useful than we imagined.

    Placebos only affect what the brain can modulate. It's not going to shrink a tumor. It's not going to deal with malaria. But it will deal with pain, fatigue, and nausea. Or will deal with feeling malaise. But it's not going to deal with killing bacteria. That doesn't happen on the level of the brain.
    ...
    The first open-label study we did was in irritable bowel syndrome. People on no treatment got about 30 percent better. And people who were given an open-label placebo got 60 percent improvement in the adequate relief of their irritable bowel syndrome.

  • Please Calm Down: Coconut Oil Is Fine

    In response to articles like: Coconut oil 'as unhealthy as beef fat and butter'

    The studies don't link eating more coconut oil to heart disease-they link it to a changing cholesterol metric. A metric that, if you look for it, has lots of conflicting data as to how it makes things worse and how badly (may I point you to Gary Taubes' Good Calories, Bad Calories).
    So, coconut oil is fine. It's not fantastic. It's not horrible. It's just a source of saturated fat probably not as bad as butter. Which we also don't think is that bad.

  • Chiropractors are bullshit

    You shouldn't trust them with your spine or any other part of your body.

    Chiropractic care, I'm sorry to say, is little more than the buffoonery of a 19th-century lunatic who derived most of his medical theory from séances. It has not evolved much since its creation. Chiropractic beliefs are dangerously far removed from mainstream medicine, and the vocation's practices have been linked to strokes, herniated discs, and even death. Chiropractors can't replace your doctor, and I'm amazed that they're still even allowed to practice. You shouldn't trust them with your spine or any other part of your body, and here's why.
    ...
    Though some chiropractors are now making an effort to introduce evidence-based practices into their treatment, chiropractic as a whole hasn't evolved like other areas of medicine -- with hypotheses, experimentation, and peer review. Instead, it was birthed by a strange combination of hocus pocus, guesswork, and strongly held religious beliefs. I'm not being hyperbolic when I cite hocus pocus. Palmer held séances to contact a dead physician named Jim Atkinson, and said that those séances helped him develop chiropractic.

  • Why I Won't Get a PSA Test for Prostate Cancer

    Physicians are still recommending the blood test for prostate cancer even though it harms far more men than it helps.

    The problem is that inflammation and other problems unrelated to cancer can also elevate PSA levels. And when the PSA test correctly detects cancer, it is often so slow-growing that it would never have caused death or even impairment of health. Detection of these non-deadly cancers is called overdiagnosis.
    ...
    Just to be clear: you are 240-120 times more likely to misdiagnosed as a result of a positive PSA test and 80-40 times more likely to get unnecessary surgery or radiation than you are to have your life saved.
