Many people like to start each new day by turning on the coffee machine. Caffeinated soda and energy drinks are also very popular now, especially among younger people. Some health experts are concerned about the amount of caffeine people are ingesting because of associated health risks. Others do not see a problem with drinking coffee and tea because caffeine has been linked to certain health benefits. So what is the truth about caffeine drinks?
The Disadvantages
Some people refuse to consume any caffeinated beverages at all
because of the negative impact they can have on human health. For
example caffeine consumption has been linked to hypertension and heart
disease. Caffeine can also make a person feel unusually nervous or
anxious because it amplifies the stress response. Caffeine may decrease
bone density, and some evidence suggests that it’s addictive. Hence a
person who drinks too much coffee may become dependent on caffeine in
the same way as a drug addict becomes hooked on illicit drugs.
The Advantages
Caffeinated beverages are not all bad news. You may have noticed that
caffeine is listed in the ingredients of many weight-loss supplements.
That’s because caffeine is known to stimulate the metabolism. Caffeine
makes it easier to cope with exhaustion and fatigue. It also increases
memory function, reaction time and concentration. Research findings
suggest that caffeine may help lower the risk of developing type two
diabetes. If you have heart condition, a small amount of caffeine can
actually be helpful. That’s because caffeine slows the flow of blood
through the heart. Furthermore, caffeine is thought to help prevent
certain types of liver disease, including liver cancer. Because caffeine
stimulates mental function, it is also thought to slow the onset of
Alzheimer’s disease.
A Balanced Approach
Since caffeine can have both positive and negative effects on human
health, deciding whether to drink it or not can be somewhat confusing.
Research indicates that in most cases there is no problem with drinking
three or four cups of coffee each day. Three or four cups of coffee per
day will provide you with enough caffeine to get the health benefits
without suffering any of the adverse effects. However every rule has
exceptions. For instance, you would be wise to avoid caffeine drinks
altogether if you suffer from hypertension, an anxiety disorder or
osteoporosis.
