Falling levels of polyamines, compounds present in all living cells, cause circadian rhythms to slow down in older mice, reports a study published October 8 in Cell Metabolism. This effect was reversed by dietary supplementation with a type of polyamine called spermidine, which is abundant in foods such as soybeans, corn, green peas, and blue cheese. No studies have yet been conducted in humans.
