| Research Abstract |
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.
