The Ask Marilyn column in this week’s Parade Magazine featured this question from a reader: “If you wished to test the effects of a placebo, what would you give the control group?” Good question. In her reply, she tells about a study in which sham acupuncture was pitted against sham pills for chronic arm pain. The patients reported that the acupuncture worked better, she says, although objective measures, such as grip strength, showed no difference. But here is another interesting finding: “…Before the study began, subjects were advised of possible side effects. About 25% of the false-acupuncture patients and 31% of the fake-pill patients reported experiencing them!” Just as eye witnesses to a crime are notoriously bad at identifying the perpetrator, human subjects are not very reliable when searching for scientific truths.
Another thing to remember about research studies is that correlation is not causation. Billions of dollars have been wasted on worthless studies that can never prove anything, and many are flawed by the bias of the researchers who tend to find what they expect to find or misinterpret the results to fit the hypothesis.
Here are two examples:
The study trumpeted as “proof” of the theory that eating cholesterol causes heart disease was a study of one group of men eating a low-fat diet versus another group of men eating the SAME low-fat diet while taking a cholesterol reducing drug. http://carbwars.blogspot.com/2011/01/good-news-bad-news.html]
The author of The China Study incorrectly reported the results of his 20-year, observational study, involving 65 thousand subjects, to support his own agenda. He got away with it because no one (until now) was willing to plow through thousands of pages of data to ferret out the contradictions. You can see how Denise Minger, who was one of the speakers on the last Low-carb Cruise, devastated T. Colin Campbell’s case using nothing but his own words.

Unfortunately, much of modern medical practice is based on shoddy research, which is very hard to dislodge once it becomes institutionalized. Never fear! The good guys are riding to the rescue. You know one of them already, I’m sure. His name is Gary Taubes. Saddle up and see how you can help out.
“This morning, at 9am Eastern Time, we officially launched The Nutrition Science Initiative — NuSI (pronounced “new see”). NuSI is a non-profit organization, technically a 501(c)(3). Its purpose is to facilitate and fund rigorous, well-controlled experiments targeted at resolving unambiguously many of the outstanding nutrition controversies — to answer the question definitively of what constitutes a healthy diet…”
