COFFEE, SACCHARIN, AND THE PILL
> It is estimated that 24% of male and 49% of female deaths from
> bladder cancer are due to coffee drinking. This accounts for 1450 male
> and 1350 female deaths per year. If it is assumed that there are 180
> million coffee drinkers in the U.S., and that each case represents an
> average of 15 years lost life expectancy, this represents 6 days.
>
> In attributing six days of lost life expectancy to coffee drinking, we
> ignore all effects other than bladder cancer, such as the known
> mutagenic properties of caffeine, and effects on the nervous system,
> weight control, etc. According to the U.S. Food and Drug Administration
> if everyone in the U.S. were to drink one diet soft drink each
> day throughout life, there would be an additional 1200 bladder cancers
> per year. A calculation similar to that above indicates that drinking one
> diet soft drink per day reduces life expectancy by 2 days. It is
> interesting to point out that ingesting an extra 100 calories per day, as
> in drinking a regular soft drink, would increase one's body weight by
> about 71b and thereby reduce life expectancy by 7 months or
> 210 days.
