Coffee - The Science - (Part 2 of 2)

Whether or not these ingredients turn out to be quite so unimportant (in physiological terms at least) in their effects on humans as they are properly evaluated in the fullness of time remains to be seen. But for the moment let's stick to what we do know. In practice then when we talk about 'The Science of Coffee' we are really talking about 'The Science of Caffeine - A little on Chlorogenic Acids and a sprinkling of other stuff - But Mainly Caffeine! Because no-one knows what the other 98% does'.

This being the case then, let's take a look at how much caffeine is typically in a whole range of drinks. (in mg)

So then it is clear that you can get caffeine from a number of sources. But if you are Mr or Mrs Average living in the USA or the UK you are probably consuming maybe 200 to 300mg of caffeine a day. Some people obviously consume much more, and others much less, but you should be able to work out very roughly where you stand by taking a look at the chart above.
