Abstract


The experiment was carried out on eight healthy male subjects of 19-22 years old and they
were maintained under the rice diet, the general mixed diet and the high animal protein diet
for 7 days of each experimental period, respectively. The composition of each diet was indicated in Table 3.
The allowance of each nutrient per head per day in each diet were as follows.
a) In the rice diet;
protein:139.5 g (animal source:64.6 g, vegetable source:74.9 g),
fat:25.3 g (animal source:11.3 g, vegetable source:14.0 g),
carbohydrate: 644.0 g, calcium:982.3 mg, phosphorus:2369.2mg, thiamine: 2.1 mg,
.riboflavin: 1.6 mg, and 3211 Cal.
b) In the general mixed diet; protein: 97.4g (animal source: 10.5 g, vegetable source: 86.9 g),
fat:40.3 g (animal source:7.1 g, vegetable source:33.2 g),
carbohydrate: 620.7 g, calcium:887.lm g, phosphorus:2200.8m g, thiamine: 1.8m g,
riboflavin: 1.9m g, and 3158 Cal.
c) In the high animal protein diet;
protein: 135.6 g (animal source: 68.8 g, vegetable source: 66.8 g),
fat: 32.5g (animal source: 17.9 g, vegetable source: 14.6 g),
carbohydrate: 930.9 g, calcium: 626.0 mg, phosphorus: 1998.9 mg, thiamine: 1.5 mg,
riboflavin: 1.5 mg, and 3194 Cal.
The absorption rates of protein, fat, carbohydrate, calcium, phosphorus, thiamine and. riboflavin in each diet were observed.
The results obtained were summarized as follows;
1. The absorption rates of protein and fat in the rice diet were 88.1% and 71.1%.
2. The absorption rates of protein and fat in the general mixed diet were 83.4% and 86.4 %.
3. The absorption rates of protein and fat in the high animal protein diet were 86.85/0´ and
82.4%.
4. The nitrogen balances in the rice, the general mixed and the high animal protein diet groups were +5.7g, +2.3g and +4.Og respectively.
5. The absorption rates of carbohydrate in each diet were all above 95% and so seemed to be almost completely absorbed except the cellulose in the diets.
6. The calory utilization rates in each diet were all above 93%.
7. The minimum absorption rates of protein, fat and calory were 83.8%, 63.3 %, and 89.7 ?5 in the rice diet, 80.0%, 80.9% and 85.9% in the general mixed diet and 83.67´, 75.711) and 89´3 % in the high animal protein diet respectively.
Therefore, it is assumed that these data might be significant in practical use.
8. The protein absorption rates of the rice diet (88.1%) was better than that of t::e general mixed diet (83.4%).
9. The fat absorption rates of the general mixed diet and the high animal protein diet (86.4% and 82.4%) were signficantly better than that of the rice diet (71.3%).
10. The calcium absorption rates of each diet, rice diet, the general mixed diet and the high animal protein diet were 41.6%, 36.0%, and 27.7%, respectively.
11. The phosphorus absorption rates of each diet were 51.4%, 56.0% and 52.3%, respectively.
12. The phosphorus absorption rate seemed better than that of calcium
13. The thiamine absorption. rates of each diet seemed 27.0 %, 42.9 % and 29.5 %, respectively.
14. The riboflavin absorption rates of each diet seemed above 30.6%, 27.1%; and 39.3% respectively.
15. The excretion amounts of thiamine or riboflavin were much more than the amounts ingested of the both vitamins.
Therefore, the certain amount of both vitamins seemed to synthesize in the intestine.
