A study on liquid diet in geriatric patients.

The intake of energy and nutrients was studied during 16 days in nine geriatrics immobilized patients who had received a conventional liquid diet for an extended period of time. The intake of energy averaged only 870 kcal/24 h. Fat intake was very low, averaging 16 g/24 h, which corresponds to 17 per cent of the total energy intake. The mean protein intake was 33 g/24 h. To improve the energy and nutrient content a food supplementation was added to the liquid diet. During the following 16 days the intake of energy increased to a daily mean of 1380 kcal. Fat and protein intake increased to 38 and 73 g/24 h, respectively. No essential change in the volume consumed after addition of the food supplementation was observed. Urinary nitrogen excretion was analyzed during the study. A positive nitrogen balance occurred after the patients had received the food supplementation.

The study of women in Gothenburg 1968-1969. Intake of energy and nutrients in five age groups.

Women from five age groups (38, 46, 50, 54, and 60 years), participating in the population study "Women in Gothenburg 1968-1969", were subjected to a 24-hour recall dietary interview (n = 1361). In a randomized subsample (n = 418), a dietary history was obtained and individuals in another randomized subsample (n = 755) submitted a 24-hour urine specimen for nitrogen analyses. There were significant differences between the 24-hour recall and dietary history figures in all five age groups with respect to energy and all nutrients. The mean protein intake calculated indirectly from the urinary nitrogen excretion came close to the figures calculated from the dietary histories in four out of five age groups. The energy intake and, consequently, the intake of most nutrients calculated from the dietary histories were higher than generally ascribed to Swedish women, as most previous data have been obtained by 24-hour dietary recall interviews. Most women (71-89% in the different age groups) consumed too much fat and most women of fertile age (80-92%) consumed too little iron. A significant decrease in the mean energy intake was apparent only in the age group 60, i.e. 1870 kcal versus 1965--2 105 in the other groups.
