How does coffee work on our brain?

 

Each beverage that contains caffeine acts on the central nervous system. 
Speaking in scientific terms, it increases brain excitability by blocking the neurotransmitter adenosine receptors. 


There goes coffee as well. When we drink it, we feel more awake, alert, and energized.


A lot of us are classic addicts to this magical beverage, and we can’t even imagine what a day would look like without our coffee ritual.

What’s maybe the most valuable part of drinking coffee every day is that there are many health benefits to it.
It can hype up positive energy, reduce the risk of type-2 diabetes, lower our cholesterol level, and many more.

Besides that, it’s even proven that a certain amount of caffeine will keep us awake plus raise our concentration if we drink it.
But, sometimes, this is not the case.
No matter how many times we reach for our favorite coffee machine, there are just not enough cups to function properly!

Our energize booster is not working.
Our productivity is low and we still feel drowsy no matter how many times we make our favorite beverage.
What’s going on?

The answer to this question is twofold. And now we are going to explain it more thoroughly.
Function of caffeine



There are two main functions that happen in our bodies when caffeine runs through our bloodstream.

First, when we consume coffee it binds with “things” that normally would cause our brain to become active.
This prevents us from sleeping properly like we were not consuming caffeine at the time.

Second, we produce more chemical messengers after drinking coffee which helps stimulate regions of the brain that are involved with self-control and willpower.
The fact is that our central nervous system is more awake and lively when we are influenced by caffeine.
Due to the coffee consumption our receptors and neurotransmitter adenosine are blocked,
and that is how we increase the excitability in brain cells.

Adenosine is a natural compound that is part of our bodies.
When that compound is fully received in the brain’s receptors, we are starting to feel sleepy.
The adenosine slows down the nerve cells’ activity,
which in turn dilates the blood vessels.

At this point, your body and your brain are in need of a cup of coffee,
thus it’s time to reach over your favorite coffee machine and pour some beverage into a mug.

Yikes, this whole process sounds like we are some medical experts, but in reality, it is pretty simple.
What coffee is good for the brain?



The longer the roasting time, the more phenylindanes the coffee beans produce.
This means that coffee that’s dark-roasted has the most protective impact on the brain.

But, what’s phenylindanes though?
They are organic compounds that are found in coffee, especially in dark roasted ones.

They have a harsher, lingering taste, which explains the bitter taste of dark-roasted beans.

Hance, espresso, and other grounded, dark-roasted coffee types will have the best protective impact on your brain. 

 
The chemical in caffeine activates so many diverse areas of the brain that it has become difficult to say which is responsible for its protective function.

Looking at the latest studies, the above-stated facts about coffee and its impact on our brains have been proven.

It actually showed that four cups of coffee per day reduced risk by 50 percent of developing dementia and Alzheimer’s later in life.

Therefore, drinking strong coffee is better than drinking decaffeinated coffee.

When it comes to intelligence, there are no guarantees that coffee will make us smarter, but it does show promise in improving our memory and thinking skills.

Stats have shown that people who consume 250-400 mg of caffeine every day had better short-term memory performance than non-caffeine drinkers
while also retaining more information over a 24 hour period.

So, dear coffee lovers, the ones that are on the caffeinated end, after this, we are 100% staying on the dark side.
Not only that we’ll have more energy but we’ll also protect our health from certain diseases.
It’s a win-win for everyone.

 

 

 

 

What coffee has the most caffeine?

Dear coffee lovers,

even though we drink coffee every day,

there are some things we still don’t know about our favorite beverage. 

 

Okay, we know that our fav brownish bean is measured as a cup of happiness,

but do we know how much caffeine is in that little mug?

What is maybe shocking for a lot of coffee aficionados, is that not all coffee has an equal amount of caffeine. 

 

Yup, that’s right. Now certain questions pop up.

For example,

what effect does the roasting profile have on the strength of your coffee?

Or which bean is stronger, lighter, or darker?

Prepare your cups, make yourself comfortable, and let’s learn something new!

 

IMPORTANT THINGS TO KNOW!

As we mentioned, a variety of things can affect the strength of coffee. 

Before we move one to the classical division, we should also know the next things!

 

  • You can always maximize the caffeine extraction by grinding your coffee beans as finely as possible.
    As a general rule, grinding your coffee beans finely will maximize caffeine extraction.
    This also can be accomplished by increasing the coffee to
    water ratio and extending the steeping time.

 

  • Another thing is that the typical serving size for a specified coffee drink must also be taken into account.

 

What are the two main types of coffee beans?

These are two main types of coffee beans : Arabica and Robusta

Coffee plants are classified into two main types: Arabica and Robusta

They gain their popularity through their origin but

they can be also characterized by caffeine content.

 

Generally speaking,

Robusta beans are considered to be inferior to Arabica beans in terms of quality. 

This is because Robusta plants are way easier to farm compared to Arabica.

 

Also, they have a kind of strong and bitterish flavor

while Arabica has a more fruity and sweet taste.

 

Speaking about Robusta beans, they are not hard-to-look-for,

since they are almost always the beans of choice

for supermarket brands that are cheaper and easier to find.

 

When it comes to Arabica,

these quality beans can also be found but with a bit more effort. 

It is obvious that Arabica is the better choice, but believe it or not,

 

Robusta coffee beans have a higher caffeine percentage

 

To be exact,

Robusta beans contain twice as much caffeine as Arabica. 

Coffee beans that are derived from Robusta plants are more scarce and mellow,

but as said,

they contain more caffeine compared to Arabica.

 

If you are a fan of strong coffee,

know that these types of coffee are the most popular

plus most instant coffees use Robusta beans.

 

All you have to do is check at the coffee label,

and check the strength of caffeine by looking at the bean type.

 

What is the coffee roasting process?

 

 

Okay, a lot of confusion has been made because of the color of the bean.

Many people think that the darker the bean the stronger the coffee.

This is actually not true.

Others think the reverse. Which is also not true.

Well, to clear all the myths and confusions.

The caffeine content in coffee beans is not diminished by roasting!

 

What actually has an impact on the roasting is the bean mass.

So, when the process of roasting begins, they slowly lose their mass.

 

This means that darker beans are roasted longer thus they weigh less

while lighter beans are roasted less thus weigh more in mass.

As a result,

a pound of dark-roasted beans will have slightly more beans compared to lighter-roasted beans.

 

coffee brewing process

 

  • Another thing that has an impact on the caffeine percentage is the process of brewing. 

A lot of coffee shops will use a scale when measuring the weight of coffee,

but it is recommended to use a scoop for the following reasons. 

 

Because of the density of the light roast,

it will contain more caffeine in your measuring scoop. 

 

Let’s try to make it easier:

Your cup of lighter roast coffee contains more caffeine than your cup of darker roast coffee.

Because lighter roasts produce denser and heavier beans.

 

So, if we measure the same quantity of dark and light roasted coffee,

even though they weigh the same, the lighter-roasted coffee will contain more caffeine.
