A few months ago, a story ran in Wired Magazine that described a noticeable shift in the scientific method, and attributed the change to our ability to produce and store large amounts of data.
Historically, the scientific method was built around a testable theory.  But in the 21st century, theories were becoming obsolete; the data simply spoke for itself.

Data from our bodies is no exception — physiologic data can now be accessed as a real-time data stream thanks to personal health monitors. But does the vast amount of data we get from our bodies make us any healthier? Do we need to collect data 24-hours a day in order to learn something interesting about our health? Is it even feasible to wear these sensors all day, every day?

I am embarking on a new self-tracking experiment to answer these questions (and possibly a few others). For 30 days, I will be using devices such as the Zeo personal sleep coach, the Philips DirectLife activity monitor, the Mio Motiva wristband on-demand heart rate monitor, and the Nike+ sportband. The goal of this study is not to pit one device against another; rather, I want to focus on what the data tells me, and how I can best use it to stay healthy.

I’ll get a blog post up here at least once a week, all the while working on a longer story about the journey that will be released at the end of the month.

Stay tuned. It should be a fun ride…

“The human body does enormously well healing itself,” Keas founder, and ex-Google Health lead, Adam Bosworth told Health 2.0 conference-goers shortly after stepping on stage.  On the heels of an article in the New York Times that touted the company’s beta launch, Bosworth walked the crowd through the way we’ll keep ourselves healthy in the future, using Keas’ platform.

Of all people, Bosworth understood the potential power of the internet on health, where the collective wisdom of the patient population could reach thousands, or millions, of other people.  So he wondered, if people were readily turning to the web for information when they got sick, could customized, preemptive web advice keep people from getting sick in the first place?

By personalizing the measures we can take to stave off certain predisposed conditions, Keas’ Care Plans should improve our health.  But the real promise of the company, wasn’t in what Bosworth delivered onstage, but rather, in something he simply mentioned in passing.  Bosworth alluded to the idea that not only will Keas’ platform let people track their own health, but it could also allow people to keep tabs on their family’s health as well.

I saw this study in Science at the beginning of the month, and a summary was posted at The Scientist:

A bacterium that infects insects may provide a biological method for stunting the spread of a range of devastating human diseases. The bacteria may protect their hosts against disease-causing pathogens by hiking up the insects’ immune response, according to a study published online today (October 1) in Science.

Basically, mosquitoes were fed a certain bacteria, called “popcorn” Wolbachia, that did two things, 1.) boosted the immune system of the mosquitoes, which made them less likely carriers of diseases such as filarial nematodes (cause lymphatic filariasis), and 2.) cut the average lifespan of the mosquitoes in half.

Researchers are looking at the future possibilities of this promising treatment — a natural way to curb the dangerous infectious diseases spread by mosquitoes.  Questions remain whether the “popcorn” bacteria could also interfere with the mosquitoes’ ability to carry more dangerous diseases, such as malaria or the Dengue virus.

I think many of us assume that if  experts say that Vitamin C can boost the immune system, then grabbing a 500mg bottle at your local health nutrition store must be a good idea.  I know I’ve been guilty of this mindset.  But it turns out that if you exercise, taking antioxidant vitamins might not be in your best interest.  There was a good summary by Derek Lowe at ‘In The Pipeline’ about a new PNAS paper that argues against popping vitamins while engaged in an exercise routine.  The study found that the experimental group that took a combination of Vitamin C and Vitamin E actually lost some of the inherent benefits of exercise, such as changes in insulin sensitivity and formation of natural antioxidants.

My only criticism of the study is that Vitamin C is capable of regenerating Vitamin E, so I wonder whether this phenomenon will carry through for all supplemental antioxidants, or if it’s limited to the particular vitamins used in this study.

I see a recurring theme in the articles that pique my interest these days, and I can’t help but wonder, yet again, if this is another example of the differences of nutrients that exist in nature, and those made in a lab?  Should we be getting our vitamins from foods instead of supplemental pills?
