本文用双盘法在自由进食条件下对40名吸烟和不吸烟者进行了膳食锌(Zn)营养状况的调查和肺功能的对照研究。结果表明吸烟使Zn摄入和吸收减少,并引起血清Zn下降,而长期膳食Zn的减少可影响肺功能。
In this study, 40 smokers and non-smokers were investigated for dietary zinc (Zn) nutrition status and control of lung function using a double-disc method under free-to-eat conditions. The results showed that smoking reduced the uptake and absorption of Zn and caused a drop in serum Zn, whereas a decrease in long-term dietary Zn affected lung function.
