Food products enriched with stable isotopes are used in nutrition to study the metabolic fate of nutrients in humans. This study reports on the labeling of green beans, white beans, soybeans and wheat with a stable isotope of magnesium (25Mg) obtained in greenhouse conditions for further studies on magnesium bioavailability. Soybean and green bean are the most efficient plant species to obtain large amounts of edible parts rapidly with a minimum loss of labeled Mg in other parts of the plants. The results obtained showed that a relatively high percentage of the magnesium found in seeds (grains/beans) can come from the redistribution of magnesium previously accumulated in other organs.
富含稳定同位素的食品被用于营养领域，以研究人体中营养素的代谢去向。本研究报告了在温室条件下用镁的稳定同位素（²⁵Mg）对绿豆、白豆、大豆和小麦进行标记的情况，以便进一步研究镁的生物有效性。大豆和绿豆是最有效的植物种类，能够以最少的标记镁在植物其他部位的损失快速获得大量可食用部分。所获得的结果表明，种子（谷物/豆类）中发现的镁有相对较高的比例可能来自先前在其他器官中积累的镁的重新分配。
