Consider that for the last year or so, we have been treated a deluge of entreaties to reduce our salt intake, with the American Heart Association going so far as to claim that daily sodium intake should not exceed 1,500 mg. This puts it at odds with the Institute of Medicine, and now European researchers whose data indicates that the healthy range for sodium intake appears to be much higher.
Our conversation about sodium, much like advice about purportedly evil saturated fats and supposedly beneficial polyunsaturated fats, exemplifies a national obsession with believing eating more or less of a one or a small number of nutrients is the path to nutritional nirvana.
A few weeks back, an international team of scientists did their level best to feed this sensationalistic beast by producing what’s become known since then as the meat-and-cheese study, because it damned consumption of animal proteins.

The authors correlate cancer mortality with age and protein intake, but they never bother to correlate it with body mass index or waist circumference, the latter of which is an increasingly important measure of body composition. Average waist circumference of the mostly older study subjects was just barely below risk thresholds, meaning that they were fat. Abdominal adiposity induces a damaging pro-inflammatory metabolic state than abets cancer development. Cancer is predominantly a disease of aging with incidence and death rates after age 50 that are 13x greater than before.
