In April, the United States Centers for Disease Control and Prevention released a study challenging the conventional wisdom that eating less promotes longevity. The study found that the very thin run roughly the same risk of early death as the overweight. And now the tide seems to be turning against a common explanation for the long-standing observation that restricting food in lab organisms from yeast to mice prolongs life.
Reduction of intrarenal and arterial AGE accumulation by food restric
tion was confirmed by immunostaining in optical microscopy
Age-related changes in arterial and kidney structures as polyuria
and proteinuria were mainly prevented by food restriction. These
data indicate that chronic food restriction reduces the accumula
tion of AGE and preserves the structure and function of the rena
and cardiovascular systems in lean rats, although it did not affec
survival of the animals between 10 and 30 mo.
An Arizona researcher found 40 percent of meat products tested from three national chain stores were contaminated with bacteria normally associated with severe hospital infections. Federal health officials, however, say more study is needed to determine whether C. diff is transmitted through food.
Quote from the British Medical Journal (2002):3
“Lowering sodium intake may have adverse effects on vascular endothelium through stimulation of the renin-angiotensin system and on serum total and low density lipoprotein cholesterol concentrations. In cohort studies, lower salt intake in people with hypertension has been associated with higher levels of cardiovascular disease and in general populations with greater all cause mortality.”
Quote about the NHANES III study from the Journal of General Internal Medicine (2008)4
“Observed associations of lower sodium with higher mortality were modest and mostly not statistically significant. However, these findings also suggest that for the general US adult population, higher sodium is unlikely to be independently associated with higher CVD or all-cause mortality.”
