38%, respectively, with no significant difference. According to Constantion, 22) the shape of a bone depends on the size and direction of pressure on the bone. In the same research, bone blood flow was found to increase and form piezoelectricity that stimu lates the formation and absorption of bone and accelerates the calcification of bone substrate when pressure is exerted on the bone.
제안 방법
5<T-score^-l) and normal (T-score그-1) groups according to WHO categories in lumbar BMD for women. Anthropometric measurements, dietary intake analysis and blood biochemistry measurements were performed on the subjects.
Korea. For the selection of the study subjects, preliminary measurements of lumbar spine bone mineral density were performed. We classified the subjects into the osteopenia (-2.
The BMDs of the lumbar spine (L2-L4) area were analyzed using Du이 Energy X-ray Absorptiometry (DEXA, Hologic, USA). The average BMD value of the lumbar spine was L2-L4.
The subjects were lightly clothed and measured for body weight, body mass index (BMI=weight (kg)/height (m2)), fat mass and percent body fat (Bio-electrical impedence analyzer, TBF-300 TANITA, Japan) while in a standing position.

2^ advised that iron can play an important role in bone formation. According to the results of their research, there was a positive correlation between serum ferritin and forearm BMD in their test subjects: 354 girls between the ages of 8 and 13. Kim39) showed that there was a positive relationship between serum ferritin and the spine bone mineral density of postmenopausal vegetarian females.
The subjects of this study were 94 college women between the ages of 19 and 30 residing in Seoul, Korea. For the selection of the study subjects, preliminary measurements of lumbar spine bone mineral density were performed.

1) was used for statistic이 analysis. Significant differences between the two groups were determined using a student t-test.
이론/모형
Food intake for three previous days was surveyed under the guidance of investigators using a 24-hr recall method. The results were analyzed for overall nutrient intake using Can-Pro 2.
The results were analyzed for overall nutrient intake using Can-Pro 2.0, the Computer-Aided Nutritional Analysis Program for Profession이s (The Korean Nutrition Society, 2002). Intake of meat, fish, and poultry (MFP), which influences the bioavailability of iron, was calculated.
성능/효과
young women, has increased.1, 2) In their efforts to lose weight and develop a leaner figure, many young woman fail to pay adequate attention to the quality and quantity of their diets. As a result, many young woman experience anemia, growth retardation, 3) hormone imbalance and mineral metabolism alterations that lead to a loss of bone mineral density and increase the risk of osteoporosis.
\31) research showed that providing 500 mL (1 pint) milk/day for 18 months to 80 young girls whose average age was 12 significantly increased bone mineral density. The authors concluded that the intake of milk increased bone mineral density and influenced the subjects' ability to maintain maximum bone mineral content. Moreover, intake of milk, which provides c이cium and protein, can restrain the function of osteoclast.
후속연구
These results suggest that the nutrition status of iron in young adult woman is important to maintain healthy bone mineral density. Further studies to broaden and deepen the knowledge of this subject are needed.
Consequently, Koreans who consume more vegetables than animal foods will be influenced by iron intake from vegetables rather than animals. However, further study in this area is needed.
