Coffee and Caffeine

Coffee and Caffeine: Study/Research Information...

Firstly, in terms of caffeine, coffee has more than tea.

Thirty minutes after a good, strong cup of coffee, your resting metabolic rate increases by as much as 10%, your blood pressure climbs, your heart rate accelerates and your breathing speeds up. You will feel more awake, more energised.

The hike in blood pressure and heart rate led scientists to believe that the caffeine in coffee could pose a heart risk. But a recent study by Harvard researchers found no significant increase in the risk of heart disease or stroke among people who drank up to four cups of coffee per day.

While studies are not conclusive on the real health risks of caffeine, there is good evidence that drinking up to three cups of coffee a day shouldn't pose any health risk. In fact, a good cuppa might actually be good for you, according to findings presented to the American Dietetic Association.

Some of the well-documented benefits of coffee and caffeine include improved concentration, faster reaction time, better short-term memory and less fatigue. In addition to this, scientists recently discovered that coffee is also an important source of flavonoids. These potent antioxidants could help to reduce the coffee drinker's risk of heart disease and cancer.

When have I had too much coffee and caffeine?
Some people should cut back on coffee and caffeine or stop having caffeine if you:

* Are prone to migraines and headaches, caffeine can trigger a migraine in some people.

* Suffer from PMS. It can possibly worsen the symptoms.

* Are taking antibiotics, bronchodilating theophylline or another stimulant such as ephedra in some dietary supplements.

* Caffeine may cause drug interactions and severe anxiety when combined with any other stimulant.

* Are trying to conceive. A few studies have linked caffeine to infertility. However, further study is being undertaken.

* Suffer from sleep disturbances. With coffee's effect lasting a few hours, it's best to have your last cup of the day before 4 p.m. if you are serious about a good night's sleep.

* Suffer from anxiety or depression. Caffeine can worsen symptoms.

* Undertake heavy exercise training. Caffeine from just two cups of coffee can limit the body's ability to increase blood flow to the heart during exercise. Stop drinking coffee at least two hours before your training session.

Genes Play Important Role In Risk For Dependence On Illicit And Licit Drugs
The genes that play a role in illegal drug abuse are not entirely the same as those involved in dependence on legal substances like alcohol and nicotine, and caffeine addiction appears to be genetically independent of all the others, according to a study led by Virginia Commonwealth University researchers.
