Male Wistar rats, 125-150 g in initial weight, 10 per group, were fed one of four diets upon arrival. All diets contained 15% fat by weight.
Rats were fed their respective diets for 7 days. The animals were fasted overnight, and presented with a 5 g meal of their respective diets containing 14C-triolein and 3H-tripalmitin incorporated into the lipid. A fecal collection was begun 4 hours later, and continued until the animals were taken. 12 hours later, animals were killed and individual sections of the intestinal tract removed. Contents of the stomach, small intestine, cecum, and colon were collected, dried, and radioactivity counted.
