Health benefits of coffee

At Vaalnest Boutique Hotel, Vaal Marina, Vaal Dam, we make a GOOD cup of coffee. The good news is that it can be good for you!
The health effects of coffee have been studied to determine how coffee drinking affects humans. Coffee contains several compounds which are known to affect human body chemistry. The coffee bean itself contains chemicals which are mild psychotropics for humans as a defence mechanism of the Coffee plant. These chemicals are toxic in large doses, or even in their normal amount when consumed by many creatures which may otherwise have threatened the beans in the wild. The primary psychoactive chemical in coffee is caffeine, which acts as a stimulant.
Recent research has uncovered additional stimulating effects of coffee which are not related to its caffeine content. Coffee contains a currently unknown chemical agent which stimulates the production of cortisone and adrenaline, two stimulating hormones.
A May 2012 study published in the New England Journal of Medicine found that coffee drinkers “who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study.” The researchers who conducted the study said that this does not necessarily provide a cause-and-effect relationship, but will help point other researchers in the right direction.
Decaffeinated coffee (sometimes called decaf) is available. This is coffee from which most of the caffeine has been removed, by the Swiss water process (which involves the soaking of raw beans to remove the caffeine) or the use of a chemical solvent such as trichloroethylene (“tri”), or the more popular methylene chloride, in a similar process. Another solvent used is ethyl acetate; the resultant decaffeinated coffee is marketed as “natural decaf” because ethyl acetate is naturally present in fruit. Extraction with supercritical carbon dioxidehas also been employed.
Decaffeinated coffee usually loses some flavour compared to normal coffee. There are also coffee alternatives that resemble coffee in taste but contain no caffeine. These are available both in ground form for brewing and in instant form.
Caffeine dependency and withdrawal symptoms are well-documented.
