Gastric test meals of Polycose, with volumes of 300, 400, and 600 ml and energy densities of 0.5, 0.7, 1.0, 1.3, 1.5, and 2.0 kcal/ml, were given to 21 men and recovered after 30, 60, or 120 min. Polycose, a polymer of glucose, was chosen as a soluble homolog of food. The results of 1134 Polycose meals were analyzed in terms of the rates of energy delivery(More)
1. Saline test meals (750 ml., 125 mM-NaCl) were given by tube into the stomachs of five subjects who were either sitting, lying on the left side, or lying on the right side. The gastric contents were recovered at 10 min. The rate of gastric emptying was assessed from the recovery of the original solution, marked with phenol red. 2. The mean volume of this(More)
1. Results were collected from thirty-three published and unpublished studies of gastric emptying. The volumes of the meals ranged from 50 to 1250 ml., and composition varied from pure carbohydrates to ordinary food. 2. From the published composition of the meals, their nutritive density, as kcal/ml. (4-18 KJ/ml.) was computed: it ranged from zero to 2-3(More)
The stomach converts food into fragments and then liquifies it before emptying it into the duodenum. Gastric emptying of liquid foodstuffs is so controlled that about 200 kcal/hr are delivered to the duodenum. The volume of the meal, its energy density (kcal/ml), and the proportions of fat, carbohydrate, and protein in the meal have minor effects on the(More)
1. Test meals of solutions and suspensions of potassium and sodium salts of a series of saturated fatty acids, from C(2) to C(18), were given to healthy subjects.2. From the volume of these meals recovered after a fixed interval the relative effectiveness of the salts of the acids in slowing gastric emptying was assessed.3. On a molar basis the salts of(More)
1. Test meals containing various concentrations of glucose, maltose, sucrose, fructose, lactose, galactose and mixtures of these solutes were given to six healthy subjects. All meals contained 40 mM sodium citrate.2. The slowing of gastric emptying produced by the disaccharides in test meals was generally consistent with the stimulation of duodenal(More)
