2004 OCT 11 - (NewsRx.com & NewsRx.net) -- An isocaloric PUFA diet enhances lipid uptake and weight gain in aging rats.
"Aging is associated with a change in the morphology and absorptive capacity of the small intestine. In young rats, feeding a semisynthetic diet containing saturated FA (SFA) increases nutrient uptake, as compared with an isocaloric diet containing polyunsaturated FA (PUFA). We tested the hypotheses that: aging is associated with a decline in lipid absorption in the Fischer 344 rat; this decline can be corrected by manipulating the fat composition of the diet; and the age- and diet-associated variations in lipid uptake are associated with ...
