Caffeine: curse or cure?

Caffeine: curse or cure?

The latest research on caffeine has good news for coffee and tea drinkers. It

suggests that caffeine may actually prevent liver damage, especially in those

who drink excessive amounts of alcohol.

But caffeine, like anything when consumed in excess, is not without its risks.

Warnings regarding too much caffeine include temporary increase in blood

pressure, increased risks of heart disease, cancer, infertility and

osteoporosis. Fortunately there is no good evidence to show that a caffeine

intake less than 300 mg, or 1 to 2 cups of coffee per day, produce any ill

effects. Concerns regarding an increased risk of bone disease can be negated

by taking enough calcium (800-1200mg per day). And those who are prone to iron

deficiency should try drinking coffee and tea at least one hour away from meals.

These beverages affect the absorption of iron due to both the caffeine and

polyphenols they contain.

One indisputable effect of caffeine is its ability to keep us awake at night.

Nurses, as well as other professionals who need to stay alert while on the job,

find it indispensable. But there is a limit beyond which it ceases to be a

useful pick-me-up. Find out if caffeine is affecting your sleep by using the

calculator at the National Sleep Foundation. Type in your daily intake of

caffeine - found in everything from chocolate to pain relievers - to see if

you've exceeded the 250-milligram limit.

People who experience upset stomachs and/or poor sleep habits may benefit from

avoiding or reducing their caffeine intake, as some people are affected more by

caffeine than others. But don't sweat your daily cup of joe too much. It would

seem that caffeine is like anything else. Used in moderation it is probably

harmless, and in light of recent research, could even be beneficial.
