For decades, Americans have organized their diet in a way to minimize their intake of saturated fats like butter and red meat. Vegetable oils and carbohydrates became a bigger part of our diet, because, we were repeatedly told, animal fats led to heart disease.
Today, however, we are learning that this
advice was bogus. A recent landmark health study has concluded that there has
never been a link between saturated fats and heart disease. The "settled
science" on nutrition wasn't quite so settled.
Writing in Saturday's Wall Street
Journal, nutrition researcher Nina Teicholz unpacks
a new comprehensive study published in the Annals of Internal Medicine which
found that "saturated fat does not cause heart disease." This theory,
and decades of government-sponsored nutritional advice can be traced back to
one scientist at the University of Minnesota, Dr. Ancel Keyes. His crusade
against animal fats began in the 1950s and has misled the public about a proper
diet ever since.
Ms. Teicholz observes:
The fact is, there has never been solid
evidence for the idea that [saturated] fats cause disease. We only believe this
to be the case because nutrition policy has been derailed over the past
half-century by a mixture of personal ambition, bad science, politics and bias.
The new study catalogs a host of problems
with Keyes' research into saturated fats. There is little reason to document
the litany of methodological flaws here except to note that the research was
conducted in a way to validate a preformed conclusion.....To Read More.....
