Most of people love coffee is obvious, caffeine. it's very good source stimulant, a substance that raises levels of physiological/brain activity. Caffeine can be found naturally in coffee, tea, and chocolate. In this case, cafeine level in the coffee may be different as it's wide range of coffee product produced with different type of coffee bean and level of roasting. also the type of coffee the drink and how much the level of sugar contain within also contribute to health itself.
example, robusta coffee contain lot more caffeine than arabica coffee ( The robusta's bean is around 2.2- 2.7% caffeine, and the arabica bean is around 1.2 – 1.5% almost twice amount cafeine in arabica compare to robusta).
while roasting level may difer the cafeine level ; more light color the bean you roast the more caffeine in it and lack of flavor/aroma compare to brown - dark roasted bean but much more flavor/aroma but lack of caffeine.
Althought there's a benefit for caffeine itself, if it consumed to much can affect our body negatively. so without further ado.. here's the benefit and the risk of consume caffeine from coffee
BENEFIT OF CAFFEINE
- Boost our brain performance and memory
Cafeine in coffee is a stimulant content. there's so much stimulant in this world ranging from cocaine, drugs, nicotine (tobbaco), methylenedioxymethamphetamine (also known as ecstasy). cafeine is in Methylxanthines stimulant class that can be found similar like chocolate and tea . it's a natural mild wakefulness and increase energy not like other stimulant that give significant boost to psychomotor like cocaine that can damage our body itself.
according from School of Arts and Sciences at Johns Hopkins University, study shows that caffeine enhances certain memories for up to 24 hours after it is consumed.
- Lower risk of Alzheimer
Alzheimer is a disease that cause neurodegenerative ( neuron cell which responsible for receiving information from outter body to our brain (smell,touch,hearing, etc) in brain stop grow and begin to dying off). It can be cause by Aging for older people while sometimes in such rare condition can happen to person with young person, genetic and head damage .
According to Alexandre de Mendonça, Laboratory of Neurosciences, Faculty of Medicine of Lisbon. Caffeine intake was associated with a significantly lower risk for AD, independently of other possible confounding variables. These results, if confirmed with future prospective studies, may have a major impact on the prevention of AD.
According to Marjo.Eskelinen from University of Eastern Finland, School of Medicine, Institute of Clinical Medicine - Neurology, Kuopio, Finland.
coffee drinking may be associated with a decreased risk of dementia/AD. This may be mediated by caffeine and/or other mechanisms like antioxidant capacity and increased insulin sensitivity. This finding might open possibilities for prevention or postponing the onset of dementia/AD.
- Lower Risk of Parkinson
Parkinson is a brain neurodegenerative disease similar to Alzheimer. The difference is Parkinson disease cannot produce dopamine for brain and mainly affecting brain pyscomotor part (responsible for how we move our body) . Dopamine is a neurotransmitter responsible for our pleasure, satisfaction, achievement celebration. without it there's a signficant change relate to loss of energy, no motivation and if it's continue will damage our brain activity. Major Stress, Depression and genes can occur a Parkinson disease.
According to M. Maral Mouradian, director of the Robert Wood Johnson Medical School Institute for Neurological Therapeutics and a professor of neurology at Rutgers University, says prior research has shown that drinking coffee may reduce the risk of developing Parkinson’s disease. While caffeine has traditionally been credited as coffee’s special protective agent, coffee beans contain more than a thousand other compounds that are less well known.
RISK OF -to much- CAFFEINE
Can Cause Addiction Effect
Just i previously mention that caffeine is a stimulant classes. it can cause addiction to our brain as it's dopamine source that our brain needs. while caffeine doesnt contagious like cocaine and other stimulants, it rather mild a sense of adiction. However, it may lead to psychological or physical dependency, especially at high dosages. when we already consume caffeine for a long time. there will be a withdrawal effect such as migrain and tiredness.
According to Juliano at Department of Psychology, American University, Washington DC ; caffeine fulfils some of the criteria for drug dependence and shares with amphetamines and cocaine a certain specificity of action on the cerebral dopaminergic system (dopamine dependency).Insomnia
due to cafeine temporary cut off neurotransmiter adenosine (it's a signal that responsible to let brain know when our body is need to rest/sleep). cafeine made us keep awake literally, i've been tried drink robusta coffee 2 hour before sleep as a result i cant sleep overnight and force me to stay awake in the next day due it's strong content of cafeine. well, that's was way back when i was younger.
Anyway. One study also found that caffeine can delay the timing of your body clock. These effects will reduce your total sleep time. Caffeine also can reduce the amount of deep sleep that you enjoy. (you can see in the source link)
