Scientists know that our perceptions about taste and texture drive our food preferences. They know quite a lot about the role of taste in this regard, and the results of some recent experiments have shed new light on the role of texture as well, particularly as it relates to foods containing starch.
Starch is a major component of potatoes, rice, corn, wheat and the enormous variety of foods derived from them. It is also added to many other products from maple syrup to pudding. In fact, starch accounts for 40 to 60 percent of the calorie content in the average Western diet, and more than that in many Asian and third-world diets.
Humans begin digesting starch in the mouth, where the salivary glands secrete an enzyme known as amylase. This enzyme breaks down starch and other complex carbohydrates into simpler sugar molecules which end up being absorbed from the small intestine into the bloodstream. Read more »

I’ve seen at least half a dozen links to the op-ed coauthored by Newt Gingrich and neurosurgeon Kamal Thapar about how the doctor used information on Facebook to save a woman’s life. (It was published by AOL News. Really.)
In brief, a woman who had been to see a number of different health care providers without getting a clear diagnosis showed up in an emergency room, went into a coma and nearly died. She was saved by a doctor’s review of the detailed notes she kept about her symptoms, etc., which she posted on Facebook. The story is vague on the details, but apparently her son facilitated getting the doc access to her Facebook page, and the details posted there allowed him to diagnose and treat her condition. She recovered fully.
Newt and Dr. Thapar wax rhapsodic about how Facebook saved a life, and sing the praises of social media’s role in modern medicine. (I’m not sure how this really fits in with Newt’s stance on health reform, within his 12-step program to achieve the total replacement of the Left…but, hey, nobody has the patience these days for so many details anyway.)
Regular readers of HealthBlawg know that I would perhaps be the last to challenge the proposition that social media has a role to play in health care. However, I think Newt got it wrong here. Read more »

Only one-third of people with major depression achieve remission after trying one antidepressant. When the first medication doesn’t adequately relieve symptoms, next step options include taking a new drug along with the first, or switching to another drug. With time and persistence, nearly seven in 10 adults with major depression eventually find a treatment that works.
Of course, that also means that the remaining one-third of people with major depression cannot achieve remission even after trying multiple options. Experts are hunting for ways to understand the cause of persistent symptoms. In recent years, one theory in particular has gained traction: that many people with hard-to-treat major depression actually suffer from bipolar disorder. However, a paper published online this week in the Archives of General Psychiatry suggests otherwise — and the findings provide new insights into the nature of treatment-resistant depression.

Reader question:
A surgeon I’m thinking about seeing said on his website that breast implants were able to be done under local + intravenous anesthetic (like twilight). Can this really be done? I always thought it was too invasive for just twilight, especially if it is under the muscle. Is there an advantage to using twilight? After looking it up, there are lots of differing opinions out there, but I think that this may just be a way for the surgeon to cut costs. What is the cosmetic surgery truth here, Dr. D?
I am not a fan of local anesthesia or twilight sleep for breast implant surgery except in rare cases (simple redos and such). The reasons are patient comfort and practicality. I place most of my breast implants under the pectoral muscles, and these muscles need to be relaxed for this to work out. That relaxation is suboptimal under less than a general anesthetic.

I case you didn’t hear the news, the American healthcare system is in financial crisis. One of the biggest culprits indicted in this crises is “unnecessary care,” with estimates ranging from $500 to $650 billion (total spending estimate is $2.6 trillion) going toward things labeled “unnecessary.” Personally I think this is an underestimate, as it doesn’t take into account the some big-ticket items:
- Brand name drugs given when generics would do.
- Antibiotics given for viral infections (and the additional cost due to reactions and resistance).
- Unproven costly care considered “standard of care” (PSA testing, robotic surgery, coronary stents).
- The unnecessarily high price of drugs.
One of the main reasons I am an advocate of EMR is to measure and analyze care, eliminating that which is wasteful, futile, or even harmful. The biggest burden on our system is not the fact that we have a hyper-complex payment system that hides the true cost of care. The biggest burden is the wasteful care that this system agrees to pay for. In fact, I suspect that the main reason our system has become hyper-complex and covert in its spending is to hide this waste from prying eyes.
It sounds easy: Just eliminate costly unnecessary care and save the system. While you are at it, why not bring world peace, eliminate poverty, and make a detergent that cleans, softens, and deodorizes all at once? Read more »
