Even more caffeine

Aug 10, 2007 08:19

Ritchie et al (2007) reports from a French cohort study that caffeine may be neuroprotective in women, but not in men. Over 7000 men and women (65 years or older) were followed over a period of 4 years, and women drinking 3 or more cups of coffee per day showed less cognitive decline than their uncaffeinated peers. Men showed no effect in Ritchie ( Read more... )

Caffeine weakens immune system anonymous August 10 2007, 14:22:39 UTC

Tea, coffee, cola, energy drinks and chocolate share the same nerve toxin (stimulant), caffeine. Caffeine, which is readily released into the blood, triggers a powerful immune response that helps the body to counteract and eliminate this irritant. The toxic irritant stimulates the adrenal glands, and to some extent, the body’s many cells, to release the stress hormones adrenaline and cortisol into the blood stream ( ... )

For every cup of tea or coffee you drink, the body has to mobilize 2-3 cups of water just to remove the stimulants, a luxury it cannot afford.

I'm pretty sure there has to be some sort of diminishing returns working on this one, as I knew several people in college who drank *only* caffeinated soda for extended periods of time (months). I wouldn't call that a terribly healthy practice (when you're sweating Mountain Dew, that's probably a sign that something is wrong, physically), but neither did they get sick or dehydrate and die.

Interestingly, Coca-cola has decided to start fighting these claims with their own. I recently bought a 12-pack of coke which proclaimed that coke is not dehydrating. I think it said "Who knew hydration tasted so good!" Hold onto that market share! It gave me a chuckle.

I don't know if I buy either claim, but I thought it was interesting that Coca-cola was now having to address the dehydration noise.
