Swine Flu -- A National Emergency With No Evidence

by Chris Masterjohn

This past Saturday, President Obama declared the country to be in a state of National Emergency in response to the H1N1 swine flu "epidemic." You can read the text of the proclamation here.

Just three days earlier, CBS News released the results of a study it had conducted suggesting that swine flue statistics are hugely inflated:

CBS News — Swine Flu Cases Overestimated?

The title of the story is an understatement. The label of the pie chart assembly shown below, "H1N1 Tests Overwhelmingly Negative," taken from the same article, is more accurate.



In July, the CDC had directed states to stop testing for true cases of H1N1 swine flu infection. Now we can only tally "probable" swine flu cases, as if most of these cases are actually swine flu.

How likely is that to be the case? CBS News surveyed state statistics prior to the CDC stop-testing order and found that only a small minority of probable swine flu cases subjected to laboratory testing — often as little as one or two percent — were confirmed to be swine flu. In fact, the vast majority of these cases tested negative for any form of flu!

Hysteria over the swine flu is building. In Massachusetts, for example, a statute passed both houses of the legislature allowing the governor to declare an emergecy and authorize police to vaccinate the population, taking children from parents, and incarcerating those who fail to comply without a trial:



Friday, the Superintendent of Grafton High School in Massachusetts closed the school down until this Wednesday due to a "possible swine flu" outbreak and directed children not to interact with one another over the break. According to the
Boston Globe article, the Superintendent claimed that two cases were laboratory-confirmed swine flu. An agent from the Grafton Board of Health, which advised against closing the school, by contrast, claimed that none of the cases were laboratory-confirmed swine flu.

The swine flu hysteria continues to build, but the CBS News study suggests the emperor is wearing no clothes.

Maternal Intake of "Saturated Fat" Causes Liver Disease -- You Know, the Unsaturated Kind of Saturated Fat

by Chris Masterjohn

According to a recent article on ScienceDaily, scientists have discovered that mothers who eat too much saturated fat during pregnancy will give their future child severe fatty liver disease once he or she becomes an adult.

The use of words in this article like "mother," "child," and "adulthood" suggests that the researchers performed some type of scientific research in humans. In fact, ScienceDaily goes so far as to claim that the researchers were studying the consumption of high-fat diets during "a woman's pregnancy."

Nowhere in the article do the authors inform the reader that
the research was performed in mice. This is the first time I have ever read of a mouse referred to as a "woman."

The most egregious distortion of the study, however, comes from one of the researchers himself:

Professor Christopher Byrne, with colleagues Dr Felino Cagampang and Dr Kim Bruce, of the University’s School of Medicine and researchers at King’s College London, conducted the study, funded by the BBSRC. Prof Byrne explained: “This research shows that too much saturated fat in a mother’s diet can affect the developing liver of a fetus, making it more susceptible to developing fatty liver disease later in life. An unhealthy saturated fat-enriched diet in the child and young adult compounds the problem further causing a severe form of the fatty liver disease later in adult life."
Really, "saturated fat" causes liver disease? This stands in surprising contrast to other rodent studies showing that saturated fat prevents liver disease:

  • A 1995 paper in the journal Gastroenterology lauded "dietary saturated fatty acids" as "a novel treatment for alcoholic liver disease" after showing that substitution of saturated palm oil for polyunsaturated fish oil reduced alcohol-induced liver damage.
  • A more recent paper published in the Journal of Nutrition 2004 showed that saturated fat from MCT oil (medium-chain fats similar to those in coconut oil) and beef tallow reduced alcohol-induced liver damage when substituted for polyunsaturated corn oil. In fact, they replaced 20 percent, 45 percent, or two-thirds of the corn oil with saturated fat and found that the more saturated fat they used, the greater the protective effect.
  • An even more recent paper published in the journal Hepatology in 2005 found that rats fed corn oil readily developed liver damage when fed over a quarter of their calories as alcohol, but rats fed saturated cocoa butter were virtually immune to liver damage when consuming the same amount of alcohol.
  • A 2007 study published in the journal Nutrition and Metabolism found that although corn oil-based high-fat diets can induce non-alocholic fatty liver disease in rodents, long-term feeding of high-fat diets based on coconut oil or butter cannot.
So how is it that "saturated fat" wound up causing liver disease in the offspring of these mice?

If we look at "supplementary table 1," we find that the "saturated fat" used in this study was mostly monounsaturated and polyunsaturated fat. In fact, 22 percent of the fat on the low-fat diet was saturated, while only 15 percent of the fat on the high-fat diet was saturated!
That means that less than seven percent of the calories from the "unhealthy saturated-fat-enriched diet" actually came from saturated fat.

The "unhealthy saturated fat-enriched diet" actually contained 44 percent of its fat as polyunsaturated fatty acids (PUFA) and almost twenty percent of its total calories as PUFA. This is in great excess of the PUFA consumption seen even in the Standard American Diet (SAD), loaded in processed PUFA-rich vegetable oils.

Apparently "saturated fat" consumed during a "woman's pregnancy" leads to liver disease once the "child" reaches "adulthood" only when the "saturated fat" is the highly polyunsaturated kind one would find in corn oil and the "woman" is a light, fluffy critter no one would ever mistake for a human.

What can we learn from this study? Perhaps that we can never trust the news account of a research study. Unfortunately we cannot even trust the quotes in those news account taken from the researchers themselves.
