✦ Synopsis
The digestive and metabolic utilization of protein (50% lactoalbumin + 50% casein) and fat (43.0% butter, 29.5 % olive oil, 14.7 % soy oil, 9.8 % MCT and 3.0 % lecithin) provided by two commercial diets used in clinical enteral nutrition (normoproteic, 16.1 % protein and 20.8 % fat, and hyperproteic, 23.1 % protein and 14.9% fat), was studied in adult rats (mean body weight 180 g). The diet containing the greater amount of protein improved the digestive utilization of nitrogen, and although nitrogen retention was optimal, it failed to rise further when the dietary protein supply was increased. The digestive utilization of fat in both diets was excellent.
