Caffeine – Why Is It So Important?

caffeine is a widely used drug that has been around for centuries. It is a naturally occurring substance in cocoa beans, kola nuts and tea leaves which are used to make coffee, tea, cola drinks and chocolate. Like we just mentioned caffeine is present in a number of dietary sources including tea, coffee, cocoa beverages, candy bars, and soft drinks. The caffeine content of these food items varies, ranging from 71-220 mg/150 mL for coffee, 32-42 mg/150 mL for tea, 32-70 mg/330 mL for cola, and 4 mg/150 mL for cocoa.

Caffeine is a good diuretic and will cause the body to lose water at a rapid rate, so hydration is the most important thing to watch for when taking this substance. Caffeine is by far one of the most widely used drugs in the world today, and probably the most widely accepted drug today.

Caffeine is a very powerful central nervous system stimulant, the effects of this drug diminish with increased usage, so a person would have to increase the intake to get the same effect as previously. It is also important to note; Larger and larger doses can become necessary to avoid withdrawal symptoms.

Caffeine is a very effective ergogenic aid, particularly for athletic events that involve endurance such as running, biking, swimming etc. The main reason it is so effective for endurance activities is because it has been shown to increase the use of fat as an energy substrate, thereby sparing glucose.

There are some risks with the intake of caffeine, so it is important to understand these risks and weight them carefully. Caffeine consumption can causes an increased heart rate and promotes the release of stomach acid which in some people can lead to ulcers. In some people it has been known to cause nervousness and anxiety. This drug causes deficiencies in some nutrients, such as the B vitamins (needed for stress), calcium (needed for bones), iron (needed to prevent anemia), as well as magnesium, potassium, and zinc. In addition, it affects the digestive process, so B12 cannot be manufactured. It is also linked to coronary vasospasms, the cause for 20% of all fatal heart attacks which kill otherwise perfectly healthy people.

This drug is probably one of the most accepted drug in society today and one of the safest also, but again moderation is always key. Caffeine can kill people who are not aware of the risks or abuse the drug to excessive levels.
