Coffee Can Be Beneficial Depending On How Much We Consume Daily.
Coffee is one of the beloved beverages that contain caffeine and it is a brewed beverage prepared from the roasted seeds of several species of an evergreen shrub of the genus Coffea. A regular 8oz cup of coffee contains 100mg of caffeine but it may range between 80 and 200mg. According to CBS news in 2009, 80% of the world’s population consumes caffeine on a daily basis with various kinds of drink and more than 50 percent of Americans drink coffee every day. Many studies have examined the health effects of coffee, and whether the overall effects of coffee consumption are positive or negative has been widely controversial. Even though coffee might cause addiction and lack of sleep, it can be beneficial depending on how much we consume daily because coffee has been shown to counteract fatigue and restore flagging performance and lower the risks of getting Parkinson’s disease, diabetes, and prevent Alzheimer’s disease.

Researchers have also found that coffee doubles glucose intake, which will greatly reduce blood glucose levels. With Parkinson’s disease, in fact, coffee is so preventative against Parkinson's that drug companies are designing experimental drugs that mimic coffee's benefits to your brain. BBC News has also reported there might be a way to prevent Alzheimer’s disease by drinking coffee. Alzheimer’s disease can happen to people with high cholesterol. Your brain has a filter that blocks harmful chemicals. The cholesterol weakens this filter, but studies show that caffeine makes the filter strong enough so the cholesterol has no effect.
However, how much we consume coffee daily in order that it can be beneficial is the most important because drinking coffee has been shown to counteract fatigue and restore flagging performance and lower your risks of getting Parkinson’s disease, diabetes, and prevent Alzheimer’s disease if we consume it in moderate amount.
