我只知道面包或麦粉制成品里如果铝的%过高会影响男性的精子。。
茶喝多不好,尤其是饭后,因为茶叶里的 molecule 会和胃里的其他东西 react, 导致消化不良。。杀精?没听过。。 |

请出示更详细的程式证明,不然别胡说。 |

Reproductive Toxicology of Aluminum in Male Mice
JUAN M. LLOBET*, M. TERESA COLOMINA*, JUAN J. SIRVENT{dagger}, JOSE L. DOMINGO*,1 and JACINTO CORBELLA*
*Laboratory of Toxicology and Biochemistry "Rovira i Virgili" University San Lorenzo 21, 43201 Reus, Spain {dagger}Pathology Unit, School of Medicine, "Rovira i Virgili" University San Lorenzo 21, 43201 Reus, Spain
Received February 22, 1994; accepted July 29, 1994
The reproductive toxicology of aluminum was studied in mice. Adult male mice were treated intraperitoneally with aluminum nitrate at doses of 0, 50, 100, and 200 mg/kg/day for 4 weeks before mating with untreated females. Decreased body weight was seen in all aluminum-treated groups. Decreased pregnancy rate was observed in the females mated with males previously treated with 100 or 200 mg/kg/day of aluminum nitrate. High-dose male mice showed significantly decreased testicular and epididymal weights, as well as significant decreases in testicular and spermatid counts and epididymal sperm counts. Spermatid counts were also reduced at 100 mg/kg/day. However, the sperm motility was unaffected, and the percentages of morphological normal spermatozoa in all mice exposed to aluminum were comparable to the values in control mice. Histological changes, including necrosis of spermatocytes/spermatids, were observed in the testes of male mice treated with 100 and 200 mg/kg/day of aluminum nitrate, whereas the tubu lar diameters were unaffected by aluminum administration. The current study demonstrates adverse effects of parenteral aluminum exposure on the mouse male reproductive system. The "no observable adverse effect level" (NOAEL) was 50 mg/kg/day.

大河网讯 空腹饮茶影响健康,为什么这么说呢?很多人整天是茶杯不离手,绿茶不离口,早上一起床也有人把喝上一杯绿茶当成习惯。但国家茶叶质量监督检验中心副研究员翁昆提醒:空腹喝绿茶,对肠胃保健不利。
相关专家翁昆说,绿茶是没有经过发酵的茶,较多地保留了鲜叶内的天然物质,其中茶多酚、咖啡碱能保留鲜叶的85%以上,绿茶中的成分,对于防衰老、防癌、抗癌、杀菌、消炎等确实有效果,是其他茶叶无法比拟的。
但是,也正是这些天然成分,假如在空腹状态下饮用,会对人体产生不利影响。空腹时,茶叶中的部分活性物质会与胃中的蛋白结合,对胃形成刺激,轻易伤胃。
因为除了会对胃肠有刺激,空腹喝茶还会使消化液被冲淡,影响消化。同时,空腹时,茶里的一些物质轻易被过量吸收,比如咖啡碱和氟。咖啡碱会使部分人群出现心慌、头昏、手脚无力、心神恍惚等症状,医学上称之为“茶醉”现象。一旦发生茶醉现象,可以吃一块糖或喝上一杯糖水,上述症状即可缓解并消失。氟假如在体内蓄积过多,则可能引发肠道疾病,影响肾功能。
所以患有胃、十二指肠溃疡的中老年人,更不宜清晨空腹饮绿茶,茶叶中的鞣酸会刺激胃肠黏膜,导致病情加重,还可能引起消化不良或便秘。
不好意思,should be 饭前,not 饭后 |
