Coffee

Keep 90 per cent of people on caffeine in most cases, by drinking coffee. One study suggests that coffee does not alert the people and activate them but may also stave off the depression, but the reason is uncertain.

An analysis of the data:

 

Coffee

 

* Analysed by researchers at the school of public health at Harvard University and Brigham and women's hospital «» data compiled from sample cover 51 thousand women took part in «the nurses health study» Nurses Health Study is › living with depression in 1996. The researchers then monitored the number of women who suffered depression after ten years and held a comparison between the amount of caffeine they consume to see if they affect this. As well as looking at other factors on health and lifestyle such as weight and tobacco smoking and exercise.

The researchers found that by 2006, 2607 women depressed or have started taking anti-depressants. And they found an inverse relationship between the amount of caffeine and mood during the study period, the more those of Ms. of caffeine daily, said the prospects of her depression. The risk women who ate the largest amount of caffeine in coffee, less than 20 per cent of women who drink coffee contains less caffeine. And not to other sources of caffeine such as tea and soda water and chocolate has no effect on depression. The researchers attributed this to contain this material on a caffeine less than those found in coffee.

In this study, women who have a lower risk of depression to a minimum, taking 550 mg (mg) of caffeine daily. Coffee content varies depending on the quality of decaffeinated coffee bean roasting method as well as other factors. And an average Cup of coffee contains 100 mg caffeine. This means, in this study, women who ate the largest amount of caffeine, drink five cups of coffee a day. The aim of this study was to prove that coffee protects against depression, but an important question about how the other variable factor.

Caffeine and the brain

 * How caffeine affects the brain?

 

Coffee

 

Stomach and small intestine absorbs the caffeine, then up to different parts of the body including the brain. And it takes more caffeine to top the amount in circulation period of 30 to 90 minutes after, leaving only a small amount of caffeine after a time between 8 and 10 hours. And between these two periods begin declining amount of caffeine, caffeine metabolism (metabolism) and analyzed by the liver. Once the caffeine to the brain, sets several targets, but the main goal is the adenosine receptors adenosine receptors. Waladinosine chemicals into the brain to suppress activity. And after wrapping it around those receptors called caffeine a series of interactions affect the activity of dopamine and dopamine is a substance of neurotransmitters that affect mood. And caffeine effect on two neurotransmitters, serotonin, steel alsirtonin Cullen acetylcholine. In addition, caffeine affects the centers in the brain related to sleep and alertness, happiness and thinking. Although discover how caffeine in the brain specifically, its influence is evident on the behavior, it helps to alert humans it enhances the activity and energy and help to resist the drowsiness.

Limitations of the study and their pitfalls

* One study is not enough whatever the accuracy to push doctors to advise the caffeine, it's important to keep in mind the limited study. Most importantly, the women's health study prospective study within epidemiology epidemiological, meaning that researchers followed study participants over time.

First

Could not find this type of study to cause and effect, it refers only to the existence of a relationship between caffeine and mood.

And possibly, as the authors of the study, the truth is that women are most vulnerable to depression or suffering from some symptoms of depression tend to shy away from drinks that contain caffeine, caffeine is not by shielding them from depression.

II

While caffeine can boost mood and energy, may also be considered that strong, so eating large amounts may lead to tension and anxiety among people living with stress or have a sensitivity to caffeine effect.

In an epidemiological study of men in Finland, with high rates of suicide and caffeine, the likelihood of suicide less than average of having seven cups of coffee a day, but increased the likelihood of suicide among those taking eight or more cups of coffee a day, and have multiplied suicide risk among men who ate 10 or more cups of coffee a day compared to men who do not consume coffee. We must keep in mind other things related to health, particularly in the short term, caffeine also negative effects, including increased blood pressure, and hardening of the arteries, high cholesterol, insulin, and possibly. So it would be premature to advise people to eat a cup of coffee or more in the morning to reduce the risk of depression or say that eating seven cups of coffee reduces the likelihood of suicide. However, the people who attend the coffee to know it's not a bad habit, but may be healthy.
