If you’re a coffee fiend, don’t freak! I’m not going to tell you to cut it out, I certainly couldn’t.
In fact, you might find I even tell you the opposite.
Let’s begin with a few fun facts you may not know about our beloved coffee:
Coffee stays warm for 20% longer if you add cream!
Coffee is technically a fruit! Coffee beans grow on a bush and they are actually the pit of a berry.
The biggest factor that determines how sensitive someone is to coffee is their genetics! (my genetics = sensitive!)
Now we’ve had a bit of fun, let's move onto some science of how coffee is absorbed into the body.
The half-life (that instant hit of energy when you first drink caffeine) in a regular healthy person is roughly 5-6 hours.
Caffeine is processed through the liver and excreted, well you know how.
During this process the caffeine crosses the blood-brain barrier; designed to keep the brain from the bloodstream. Once the caffeine hits the brain it blocks the effects of a hormone called adenosine. This hormone is responsible for energy transfer and sleep production.
That’s enough of the science, let's talk more about what coffee is actually good for.
Caffeine takes effect in about 15mins and supports alertness and reduces sleepiness.
It actually helps to reduce post workout pain.
In more recent studies, evidence now shows it is proven to help the liver - especially from the effects of alcohol.
It is a natural thermogenic helping to speed your metabolism and burn fat fast.
In summary, coffee is a great workout based drink to pre-fuel your workout and increase your recovery for 5 hours after.
But, everything in moderation.
Overuse of caffeine can have serious negative effects almost immediately, such as:
Or over long term:
How you react to coffee depends on your body mass, state of health, metabolism, whether your body is used to getting regular doses of caffeine a day and how much you consume in one serving.
Research suggests that 400mg per day or less is considered an acceptable dose of caffeine (a standard cup of coffee generally consists of 95mg of caffeine, but different coffees and different beans will differ on caffeine content). Also don’t forget to account for fizzy drinks and other products that contain caffeine.
Happy Coffee Drinking.
