Caffeine, like chocolate, often gets bad promotion. Whilst in some instances, and over, these can have negative impacts on our body, they can also be rather beneficial.
I am not contesting that some individuals are more delicate to the negative effects of either caffeine or chocolate. Excess caffeine can produce stress and anxiety, queasiness (specifically if taken on a vacant belly), an increase in heart rate, and even depression in some individuals.
Researchers have turned up some interesting facts on caffeine. Caffeine in fact blocks the effects of a natural chemical in the brain (adenosine) that otherwise makes us feel worn out. This is why it works so well to keep us awake. It also encourages the release of an additional brain chemical, dopamine (as well as adrenaline). Dopamine adds to a sensation of well being.
2 researches, one a population based study (which are not as particular or carefully defined as other types of research studies, but nevertheless useful indications) found that drinking caffeine containing drinks like coffee and tea had a safety effect for those at risk of establishing liver disease. Concerns that the research participants had that enhanced their risk of liver condition consisted of alcoholism, hepatitis B or C, obesity, or other problems.

And the results indicated that people who consume more than 2 cups of coffee a day had a 44 % lower chance of revealing actual liver damage compared with those who drank no caffeine. This was not a clinical trial, and the reason why coffee and tea had such a result is not known. Coffee and tea include a range of plant chemicals (phytonutrients) that could be accountable for this. A 2005 Norwegian research study also found similar advantages for coffee with regards liver disease. This research discovered that drinking 3 cups of coffee a day might decrease the threat of death from liver cirrhosis.
Even if you’re not at risk of liver disease, caffeine still has some advantages. Recent study from Austria showed that caffeine may in fact enhance short term memory. An additional, earlier study (2004) found that caffeine did support short term memory, but only when it was in relation to a topic that people were currently thinking about.
Everything does have another hand though. Adenosine, which is blocked by coffee, is likewise soothing. This could be why it can likewise trigger stress and anxiety in excess, and in some people. After all, the balance of our brain chemistry is unique. And when we are addicted to stimulants like caffeine, we lose the sensitivity to our own natural stimulants (dopamine and adrenaline).
