Dietary Chromium intake, excretion and balance in healthy young Japanese women.

铬（Cr）是一种必需的微量元素，对正常的碳水化合物代谢很重要，它在动物中的缺乏会导致糖尿病样状态。这些研究旨在测量和评价健康年轻日本女性的铬摄入量。1）膳食铬摄入量为26.9 +/-20.4 [micro-] g/天。尿Cr排泄量为25.2 +/-53.6 [micro] g/天。我们发现铬摄入量和尿排泄量之间呈正相关，特别是在2天后的强相关性。2)计算得出的铬平衡为59.2 +/-27.1 [微]克/天，与铬摄入量显著相关。此外，我们观察到，铬摄入量可以估计尿铬排泄。3)运动（60%HR max，30 min，5 d）减少尿Cr排泄。

Chromium (Cr) is an essential trace element and is important for normal carbohydrate metabolism, and its deficiency in animals can cause a diabetic-like state. These studies aimed to measure and evaluate the Cr intake in healthy young Japanese women.1) Dietary Cr intake was 26.9 +/- 20.4 [micro]g/day. Urinary Cr excretion was 25.2 +/- 53.6 [micro]g/day. We found a positive correlation between Cr intake and urinary excretion, especially a strong correlation after 2 days. 2) Balance of Cr was calculated as 59.2 +/- 27.1 [micro]g/day, and significantly correlated with Cr intake. Additionally, we observed that Cr intake could be estimated by urinary Cr excretion. 3) Exercise (60%HR max, 30min, 5 days) was decreased to urinary Cr excretion.
