Protein and lysine digestibility and protein quality of cooked Filipino rice diets and milled rice in growing rats.

The protein quality of typical rice-based menu of Filipino preschool child and adult and cooked milled rice was assessed for true digestibility (TD), biological value (BV) and net protein utilization (NPU) in growing rats. Lysine and energy digestibilities were also determined. For the preschool child diet, TD was 88.8%, BV 90.0%, and NPU 79.9%. For the adult diet, TD was 87.3%, BV 86.6%, and NPU 75.5%, whereas cooked rice had 90.0% TD, 82.5% BV and 74.3% NPU. Lysine digestibility was 95.4% for preschool child diet, 95.7% for adult diet, and 100.0% for rice. Digestible energy was 91.3% for preschool child diet, 93.0% for adult diet, and 95.3% in rice. Amino acid scores were 100.0% for preschooler diet, 92.1% for adult diet, and 62.2% for rice. Protein quality based on amino acid score corrected for TD was 88.8% for preschool child diet. 80.4% for adult diet, and 56.0% for rice. If based on lysine digestibility instead of TD, protein quality would be 7.1% higher.

Hormonal status of gastric cancer. I. Effect of rice and salty rice diets on the constitution of urinary steroids in mice.

We investigated the effect of rice and salty rice diets on the physical growth and on the constitution of urinary steroids in Swiss/ICR mice. The following three kinds of diets were employed in the feeding experiment: 1) standard diet; 2) rice diet; and 3) salty rice diet. Long-term maintenance of mice on both rice and salty rice diets led to a relative increase of tetrahydrocortisol associated with a concomitant decrease of androgen, progestin, and cholesterol in urine. Evidence was presented to indicate that the activity of endogenous hydrocortisone in mice could be augmented by an increased intake of sodium chloride alone; there was also evidence that the glandular stomach of a young mouse drinking physiological saline is highly sensitive to a suppressive action of hydrocortisone. We concluded that the two experimental diets produced a state of catabolic glucocorticoid excess combined with a deficiency of anabolic androgen and progestin. Mineralocorticoid status was not examined. In the salty rice diet, a markedly lower weight gain was observed, whereas in the rice diet, in general, no significant weight changes were observed.

Effect of rice and salty rice diets on the structure of mouse stomach.

The effect of rice and salty rice diets on stomach morphology was investigated in Swiss/ICR mice. Mice were fed rice, salty rice, or standard pellet diets for 3-12 months, starting when the mice were 4 weeks of age. Long-term maintenance on the rice or salty rice diet increased the dimension and wet weight of the forestomach and decreased the same parameters of the glandular stomach. Similar bidirectional changes of the forestomach (hypertrophy) and glandular stomach (atrophy) were produced by hydrocortisone treatment. Histological study showed that a reduction in the parietal cell population accounted for the regression of the glandular stomach in both cases. Evidence is presented to suggest that an excess of carbohydrate and sodium chloride combined with a deficiency of fat and protein produced steroidal disorders that in turn gave rise to hyperplasia of the forestomach and atrophy of the glandular stomach of the mice. Possible impact of the above findings on the genesis of human gastric cancer is discussed in relation to the metabolic competence of the host animals to synthesize vitamin C.

A rice diet is associated with less fat synthesis/accumulation than a bread diet before exercise therapy.

For effective exercise therapy after waking up, we focused on the staple food in diet therapy, and compared rice and bread diets. The subjects were 10 healthy college male students. After fasting for 12 h or more from the previous day, the subjects had breakfast consisting of rice (protein, 6.3 g; fat, 0.9 g: CHO, 79.3 g; energy, 368 kcal) or bread (protein, 15.7 g; fat, 5.8 g; CHO, 79.2 g; and energy, 450 kcal) containing the same amount of carbohydrates and the same side dishes (protein, 7.0 g; fat, 9.5 g; CHO, 21.3 g; energy, 199 kcal) in the morning 30 min before the initiation of exercise on a bicycle ergometer at an intensity of about 50% VO2max for 60 min. Measurements of the heart rate and expired gas were initiated 15 min before the start of exercise and continued until 10 min after exercise. Blood was collected before the meal, immediately before and 15, 30, and 45 min after the initiation of exercise, and immediately, 15, and 30 min after its termination. After breakfast containing carbohydrates, decreases were observed in the levels of free fatty acid and noradrenalin. Blood insulin (mealxtime, p<0.05 ANOVA) and triglyceride (meal x time, p<0.01, ANOVA) changed at higher levels in the bread diet than in the rice diet. Blood triglyceride is a resource of fat synthesis/accumulation, and insulin promotes its action. Therefore, the bread diet may promote fat synthesis/accumulation compared with the rice diet.

Effect of lysine and threonine deficient and supplement rice diets on lipids of hepatic smooth and rough endoplasmic reticulum of rats.

Effect of feeding lysine and threonine deficient and supplemented rice diets to rats for fifteen days has been studied on the lipids of hepatic smooth (SER) and rough endoplasmic reticulum. The deficient diet reduced protein and phospholipids of SER where as it increased triglycerides contents of both SER and RER compared to rats fed the supplemented diet.

A comparison of unrefined wheat and rice diets in the management of duodenal ulcer.

Twenty-one chronic duodenal ulcer patients in a rice-eating area were put on to an unrefined wheat diet and twenty-one continued on their previous rice diet. After 5 years only 14% of the first group had had relapses compared with 81% of the second group. A similar 5-year relapse rate (80%) was obtained in a group of thirty patients from another area with a more varied rice diet. The author attributes this difference to the increased mastication required by the unrefined wheat diet, which is associated with an increase in saliva, lower stomach acidity and reduced bile output.
