There was a man with tongue of wood

There is the old Middle Eastern story of the one who journeyed East in search of wisdom. He came upon a stone where he read, “Turn me over.”
He picked up the stone and read on the underside: Why do you seek new knowledge when you do not use that which you already have?

A recently reported Swedish study that followed 71,000 individuals over a 13-year period found that consuming less than five daily servings of fruits and vegetables was associated with higher mortality and shorter survival periods. Those eating one serving of fruit daily lived 19 months longer on average, while those eating 3 servings of vegetables lived 32 months longer.

Now by itself, this is not very surprising. We know that heavy meat consumption is linked to colorectal cancer, particularly in combination with genetic mutations, as described in a recent issue of Smithsonian Magazine. So, the possibility that a different diet would be protective, even by contrast, makes some sense.

Fornaciari subsequently analyzed bone collagen of King Ferrante and other Aragonese nobles, revealing a diet extremely reliant on red meat; this finding may correlate with Ferrante’s cancer. Red meat is widely recognized as an agent that increases risk for mutation of the K-ras gene and subsequent colorectal cancer. (As an example of Ferrante’s carnivorous preferences, a wedding banquet held at his court in 1487 featured, among 15 courses, beef and veal heads covered in their skins, roast ram in a sour cherry broth, roast piglet in vinegar broth and a range of salami, hams, livers, giblets and offal.)

In a similar vein, one out of three Americans suffers from hypertension (high blood pressure), a major risk factor for serious cardiovascular events such as stroke and heart attack. A recent study in JAMA showed that 18 months after the beginning of a study in which the experimental group did home blood pressure monitoring along with pharmacist case management, 71.8 percent had controlled blood pressure compared to the control group with usual care at 57.1 percent.

It would be easier if we had pills that would lower our body weight or a vaccination against high blood pressure. We don’t. But we have knowledge that we are not using: walk more, eat less processed foods and more whole grains, vegetables, and fruits, monitor blood pressure and pulse regularly. No, it is not magic–just the best that we can do.
