Organic Food Debunker was Tobacco Institute Researcher in 1976

By Michael Collins

A widely publicized study claiming that there is no demonstrated difference in nutritional value between organically and conventionally grown foods just appeared in the Annals of Internal Medicine. Broad mainstream media coverage produced headlines like Stanford Scientists Cast Doubt on Advantages of Organic Meat and Produce. The media failed to mention one point that may be of major interest.

The study relied on a statistical technique called meta-analysis. Over 200 plus scientific journal articles were combined as the data set for the study. The article co-author with recognized expertise in meta-analysis, Ingram Olkin, applied for a grant from Council of Tobacco Research (CTR) in 1976.

CTR was part of the infamous Tobacco Institute, an industry group of cigarette manufacturers. Ingram was on the faculty of Stanford University at the time. The authors of the current study diminishing the value of organic foods are also from Stanford University, with Olkin listed as a professor emeritus.

Olkin applied to the CTR to conduct a project on the statistical methods used in the Framingham Heart Study, the landmark project linking cigarette smoking with increased risk of heart disease. From publicly available tobacco industry documents, we find this from cigarette manufacturer lawyers:

“I met with Dr. Olkin and Dr. Marvin Kastenbaum [Tobacco Institute Statistics Director] on December 17, 1975, .at which time we discussed Dr. Olkin’s interest in multivariate analysis statistical models. Dr. Olkin is well qualified and is very articulate. I learned, in visiting with Dr. Olkin, that he would like to examine the theoretical structure of the “multivariate logistic risk function.”

Once Is Not Enough — TSA Doubles Down on Scanning

It looks like TSA has reached a new low. According to this piece at Politico, TSA’s “new policy also will include measures to screen young children without resorting to an intrusive pat-down of private areas on the body.” That’s good news, of course, but catch this in the fourth paragraph: “The TSA plans to reduce the number of pat-downs given to children by asking screeners to send children through metal detectors, or to walk through imaging machines multiple times to capture a clearer picture.” (Image:  Rain Rabbit)

“WALK THROUGH IMAGING MACHINE MULTIPLE TIMES”? Walking through an imaging machine exposes a person to radiation. Exposure to radiation causes cancer. The more times you walk through, the more radiation you’re exposed to.

No amount of exposure to radiation is 100% safe, but everything in life is risky; could this risk be reasonable? Some experts are not convinced that it is. Here is a letter from four scientists, Dr. John Sedat, Dr. David Agard, Dr. Marc Shuman, and Dr. Robert Stroud, who are experts in relevant fields including biochemistry, biophysics, and imaging. In addition to their general concerns about ensuring that the dose be controlled, these scientists express a special concern for children: They say, “The risk of radiation emission to children and adolescents does not appear to have been fully evaluated.”

It’s bad enough that anyone has to walk through one of these machines of unproved safety to get on an airplane. It’s worse that children – who are more vulnerable than adults to radiation – have to do it. But it is worse still that children may have to multiply their exposure by walking through more than once.

As an aside, the bright side of this is TSA’s tacit admission that maybe the sexual assault that is called a “pat-down” is not a good thing for a child. In time maybe they’ll figure out that it’s not a good thing for adults either.
