title: Dietary analysis of Japanese patients with chronic pancreatitis in stable conditions.
abstract: In order to examine the malnutritional condition of outpatients with pancreatitis, a dietary investigation was conducted in Japanese patients with chronic pancreatitis (n = 38) and healthy subjects (n = 35) of the same age for 3-7 consecutive days, and the characteristics of their food intake were examined. The patients with pancreatitis took in less calories, fat, carbohydrate, and protein than the healthy subjects, by 900 kcal, 20 g, 150 g, and 20 g, respectively. On the other hand, the fat energy ratio in the patients was 20%, similar to that in the healthy subjects. Also, when the fat intake was classified according to origin, i.e., animal, marine, or plant, the proportions for animal (g) and plant (g) were low, while marine fat accounted for a significantly higher percentage than in the healthy subjects. The intake of cholesterol and Ca in the patients was significantly smaller than that in the healthy subjects, but no significant difference was observed in the intake per body weight of proteins and Ca. It seems, possible that the low calorie, low protein, low fat, and low carbohydrate intake may be factors in the malnutritional condition of the patients with chronic pancreatitis. Analysis of covariance and principal component analysis showed that the body weight of the patients was closely correlated with decreases of caloric intake and intake of carbohydrate. The above results revealed that low body weight in patients with chronic pancreatitis was closely related to the decrease of calorie and carbohydrate intake, in addition to maldigestion and malabsorption of nutrients.
