Coffee coffee coffee, no single person’s day is done without having a cup of coffee.  Coffee is the best friend for many of us.  Recent reports show that scientists (ourselves) are the biggest coffee drinkers of all. Drinking coffee makes you alert and these effects are due to caffeine present in coffee. Caffeine works by blocking the effect of brain’s natural regulator, adenosine, that makes your body sleepy. Morning (9:30AM-11:30AM) and afternoon (1:30PM-5PM) are considered the best times to drink coffee as during this time the levels of cortisol, a natural chemical that keeps you alert, drops off, as guided by the body's 24-hr biological cycle called circadian rhythm.  Coffee also contains many different compounds that are good for health, which include antioxidants, which protect our bodies from damaging “free radicals”. National Institutes of Health (NIH) studies show coffee drinkers have reduced effects risk of Alzheimer’s , Parkinson’s, type 2 diabetes and many other diseases. Brains can become unhealthily addicted to caffeine, causing one to consume more coffee.  Though there are several health benefits of coffee, it does have a whole bunch of side effects that include hyperglycemia, fast heartbeat, diarrhea and also effects on central nervous system. Hence, friends, just don’t drink too much coffee. Consume carefully - maybe just 1 or 2 cups a day.
