Another issue: caffeine stimulates the production of stomach acids.

That's a no-no!

I gave up caffeine in 1995 when I got an ulcer. Occasionally, I will

have a caffeineated drink, but only very occasionally. And, boy does

it hype me up!

Caffeine inhibits the secretion of Antidiuretic Hormone (ADH) by the

hypothalamus (in the brain). It is the neurohormone that tells your kidneys

to reabsorb the fluids. ADH controls body fluid volume by decreasing the

water lost by sweating and causes the kidneys to return more water to the

blood. Anything that inhibits ADH is a real pisser. ADH is also known as

Vasopressin.

So, should we avoid caffeine altogether?

I plan to continue my morning cup of coffee and my rare diet Pepsi.

Moderation in all things..

RDS can be *very* opinionated.. especially when there is no evidence-- or

evidence is conflicting-- to support their views.

I don't have any tummy problems-- so the acidity of the coffee is okay with

me. The carbonation in the soda is a problem in that it sets up a response

that helps to leech the calcium from the bones. There are some sites that

say that caffeine in coffee also does this. Adding milk to the coffee has

been suggested as a way to help increase calcium intake. I have not read

the professional literature on this.
