Coffee & Tea-The Artifical Stressors A Review of the Negative Physiologucal & Psychological Effects of the Xanthines

P(論文)Evidence is reviewd to show that the physiological and possibly psychological effects of the xanthines are similar to those of the "fight of Flight" reaction with the implication being that the caffeine and theophylline in tea, coffee, and various xanthin-containing beverages and drugs induce the same changes in the body as stress. A number of "at risk" populations are identified who should best aboid any xanthine consumption. The issue of the "safe" dose is discussed and the position is taken that, given the great individual variation in sensitivity and the large number of factors affecting the toxicity of the xanthines, caution is suggested in recommending any one "safe" dose.departmental bulletin pape
