is cofee really injurios to health?

Coffee contains a complex mixture of chemical compounds. Some components, particularly those related to the aroma, are produced during roasting of the green beans. The substances which during "brewing" dissolve in water to form the beverage are classified as nonvolatile taste components. Caffeine is used in treating migraine, either alone or in combination. Too much caffeine can produce restlessness, nausea, headache, tense muscles, sleep disturbances, and cardiac arrhythmias (irregular heartbeats). Because caffeine increases the production of stomach acid it may worsen ulcer symptoms or cause acid reflux ("heartburn").Evening use of caffeine may disrupt sleep and cause insomnia. Caffeine should be used with caution by people with heart disease and high blood pressure (hypertension), and by those suffering from the eye disease glaucoma.

For each and every thing we have plus and minus i suppose.Even thing in this world has it.Like wise coffee also has.I hope it is not good to take too much of coffee as it harms our health.You can take once but not more than twice. Have a nice day

Drinking too much coffee can be harmful. If you drink coffee on a empty stomach it will cause acid to build up and cause heartburn and acid-reflux. Like with anything else drink coffee in moderation.
