FIGURE 5.

Average antioxidation activity(-c,h) during 6 h after consumption of bevrages by heavy drinkers. Plasma antioxidant activities as a function of time after consumption of three alcoholic beverages for two heavy drinkers. The counts per minute were obtained with the Lumac Biocounter M2010. Hydrogen peroxide was incubated with the luminol bound to albumin, as described in Figure 1. The counts were normalized by dividing the counts/min obtained at the different times after beverage consumption by the average of six or more determinations of the count rate of the plasma taken immediately prior to beverage consumption. The graph shows plots of the average pro-oxidant activity (percent increase from a minimum of six normalized counts at each time, as a time-weighted average) for the different beverages consumed. The beverages consumed are described in the text: red wine, lager beer, stout, alcohol-free stout, and water containing 5% alcohol.
