Benefits of caffeine - Improve your memory, the wind?

Caffeine, like chocolate, is often in bad publicity. Although in some cases, and can have negative effects on our body, it can also be very useful.

 I do not deny that some people are more susceptible to the adverse effects of caffeine or chocolate o. For example, too much caffeine can cause anxiety, nausea (with namer on an empty stomach), increased heart rate, and also the Depression in some people. And the chocolate is not something that should be the basis of the diet. If the dependence struggling with sugar, or who want to lose weight, there are more nutritionally complete foods available.

 But scientists are now some interesting facts about caffeine. For example, caffeine actually blocks the effects of a neurotransmetteur in the brain (adenosine), that makes us tired. This is why it works so well for us awake. Essoinoltre stimola the release of another brain chemical, dopamine (and adrenaline). Dopamine contributes to a sense of wellbeing.

 Two studies, one study based on a population (not the most precise and accurate as other types of studies, but valuable indicators) that the consumption of beverages alkoele coffee and tea cafeinele has a protective effect for people at risk of developing liver disease. Questions that the participants study the increased risk of liver disease included alcoholism, hepatitisB or C, obesity, or complications.

 And the results showed that people who drank more than 2 cups of coffee a day were 44% chance to show the actual liver damage compared to those who drank caffeine pals. Not a clinical study and the reason why coffee and tea had such an effect is unknown. Coffee and tea contain a number of chemical plants (fytochemicstraniero) that may be responsible. In 2005, a similar Norwegian study tambienbenefiCIOs coffee against liver disease. This study showed that drinking 3 cups of coffee per day in May, the risk of death from liver cirrhosis.

 Although nietdet risk of liver disease, caffeine has its advantages. Recent research from Austria showed that caffeine can improve short term memory. The researchers found that there was an increase in hersenactATTIVITÀ (measured with functional magnetic resonance imaging), and in parts of the brainor asociand with memory and attention. Those parts of the brain, the frontal lobe and anterior Cingulum. This study was a placebo-controlled, ce, which means that some people do not have caffeine. Another previous study (2004) has shown that caffeine is not a short term memory, but only when I was on a topic that people already think. This study concluded that the evidence controuno the effects of coffee on independent entities, abreve-term recall was inhibited.

 Any failure of one hand. Adenosine, which is blocked by coffee, is also reassuring. This kanworden why it can also lead to an excess of fear, and in some people. Indeed, the balance of our brain chemistry is unique. And if they are employees of stimulants like caffeine, we lose our sensitivity to stimulants (dopamine and adrenaline).
