The different effects of oral sucrose and glucose on alimentary lipaemia.

1. A formula breakfast containing protein, carbohydrate and fat was given on two occasions to nine middle-aged male convalescent patients and to ten young men. The meals differed only in the type of carbohydrate given; sucrose or an isocalorific amount of glucose. 2. After the formula meal containing sucrose; (a) the alimentary lipaemia was cleared more slowly; (b) insulin response was smaller, and (c) there was a lower blood sugar curve than after the glucose meal. 3. The degree of lipaemia showed a significant positive correlation with insulin response which was, as expected, lower after sucrose than glucose.
