Transcripts
Hello everyone It's coffee time Tell me: what's your
favorite type?
Lungo, Espresso, Americano, Ristretto? With or without
sugar?
After water, it's the most consumed beverage in the world.
90% of French admit they're crazy for it.
Is consumption of coffee really good for health?
Does it really prevent sleep, as they say?
Let me tell you the truth... With no filter, I promise
Let me start with numbers:
2.6 billion cups. That's,
the real quantity of coffee consumed every day around the
world.
Two out of three inhabitants drink it on the planet,
in various forms.
Turkish coffee... espresso... or filter coffee.
And that makes it the top exported commodity,
right after oil.
No wonder it's referred to as,
the new black gold.
The French are fond of it. And yet, they are far from being
the biggest coffee drinkers in the world.
The finns, indeed,
lead the way with 7.4 kilograms of coffee per year per
person.
In second and third positions,
are the Dutch and the Swedes, each consuming roughly 7
kilograms of coffee per year per person.
Before telling you whether coffee prevents you from sleeping
or not,
first I need to tell you,
the incredible saga of this drink.
Coffee is produced in 90 countries, mainly in Central and
South America. And yet, coffee is not native to this region
of the world. It actually comes from,
another continent, that is,
from Africa.
It is said that an Ethiopian shepherd accidentally
discovered coffee, thanks to his goats.
While he was herding his flock, he noticed that his animals
became frisky and danced after eating the fruits of the
coffee plant.
It's a legend.
However, it is indeed in Ethiopia that the idea of consuming
the coffee beans would have sprouted.
The very first written records about coffee date back to the
9th century.
They refer to its invigorating effects and its role in
aiding digestion.
Recent excavations suggest that in prehistoric times,
coffee was already part...
of the diet of inhabitants of this region.
From the 15th century, the Arab people
would spread the cultivation of coffee plant across the
middle East and the Arabian Peninsula.
They also had,
the idea to roast these beans. They call it kawa... a Yemeni
word meaning invigorating.
Over the years and travels,
the word evolves.
It is then known as kaveh in Turkey,
kai-fey in China,
In Denmark, it's Kaffé,
with a K.
in Italian, it's caffè. And coffee in English.
This word has similar sounds from,
one language to another.
In Europe,
people had to wait until the 17th century for coffee to
appear on tables.
And for good reason
Arabs are closely watching it.
That's right,
They won't kill the goose that lays...
the golden eggs. They banned the exports of plants and even
seeds.
They only sold to Europeans,
gray beans, in other words, beans that were boiled or old
ones, not fresh enough to sprout and produce bushes.
But in sixteen sixteen,
merchants from Holland managed to steal a few coffee plants
from them.
And since the coffee plant needs warmth and humidity, they
planted it in their colonies in Indonesia.
Seeing the success of this operation, the English did the
same. And that's how coffee plants ended up in India, a
British colony.
At this stage in history, there are no traces of coffee on
the American continent.
But it's getting close.
In 1714,
The city of Amsterdam offered a coffee plant to Louis the
fourteenth.
The French monarch appreciates this beverage.
The coffee plant is grown in a greenhouse, it bears fruit,
but to produce the wanted beans,
it needs a climate more suitable than the mainland one.
So,
like its neighbors did,
France...
transfered young coffee plants to the tropics, in its
colonies, first to Martinique, then to Guadeloupe,
Saint-Domingue and Guyana.
And it worked
Coffee became a fashionable drink at court and in Paris.
Coffee houses opened in the capital city, including the
famous Procope,
which still exists today.
Thanks to these plantations, France even became,
the world's leading coffee producer for a period of time.
The Spanish and Portuguese, settled in Central and South
America, not far from the West Indies, then understood,
the several advantages they could also reap from production
of coffee beans.
Since no one wanted,
to give them any,
they decided,
to steal coffee plants from the French.
and placed them in their colonies.
The plant found ideal conditions and its cultivation spread
over a vast territory.
Over the centuries, it will become one of the emblematic
crops of this entire region of the world.
Today, 90 countries produce a total of 10,000 tons of coffee
per year.
Most of it in South America and Central America, with Brazil
taking the top position on the podium.
Accounting for 30% of global production.
As per experts, the best coffee in the world is produced on
the Department of Réunion. Thus, in France, in the Indian
Ocean,
It's known by a very pretty name,
that is, Bourbon Pointu.
Bourbon for Bourbon island, the former name of Réunion, and
Pointu, meaning sharp, due to the shape of its fruits.
Look at these beautiful cherries,
it makes you want some.
And yet...
they are not meant to be eaten.
Well,
not in this form.
These are the cherries of the coffee plant.
This tropical shrub can grow up to five meters tall.
These fleshy cherries have a pit that is divided into two
parts, the famous coffee beans.
Obtaining the beans is a complex operation. First, peel off
the skin,
then The pulp and finally the husk that covers the beans,
what's called the parchment.
There's just one spot on earth with nothing to do,
in Thailand,
The beans
are all harvested directly,
from the elephant droppings.
The pachyderm,
feeds on the coffee plant branches,
but it doesn't digest the pit of the cherries.
Yuck
That's disgusting
It seems not to be the case. It produces a,
very flavorful coffee, which, it is said, one remembers for
a long time.
Maybe also because of its price, up to two thousand three
hundred euros per kilogram.
Once extracted, the coffee beans have no smell.
The aromas are trapped inside.
To release them...
the coffee needs to be properly roasted, that is,
heated
and toasted.
The aromatic palette of coffee is very significant, more
than that of wine.
There are up to 800 different aromas compared to 500 to 600
for wine.
This time,
all that's left is to grind it.
And that brings me to the original question,
does coffee keep us awake?
The word might be a bit strong,
but what's certain is that...
after having a cup of coffee, we feel energized, prepared to
begin afresh instantly. It's because of the caffeine.
Identified for the first time in coffee, this molecule is
present in about sixty plants.
Tea,
maté,
and even chocolate. This molecule has the effect of
stimulating the nervous system. That's why our heart rate...
sometimes speeds up...
after drinking a bit of coffee.
It also slows down the accumulation of adenosine in the
brain.
This is a molecule responsible for signaling the state of
fatigue to the body.
That's why we feel that coffee wakes us up or prevents us
from sleeping.
So that's it.
To take a nap,
I should drink an Americano.
Well, no.
If they are stronger in taste,
Espressos are not actually the ones with the most caffeine.
The dose of caffeine depends on the contact time between the
ground coffee,
and the water.
Indeed, the longer the coffee is drawn out,
the longer this contact with water lasts.
Moreover, caffeine doesn't act immediately. It takes about
30 minutes to take effect.
Then, it takes between 4 to 6 hours for the body to
eliminate 50% of it.
10 to 12 hours post-ingestion,
there can still be up to 25% left.
As a result,
if you drink a small cup of coffee around 5 PM, well, then
at 11 PM, you will still have about 25 milligrams of
caffeine left in your blood.
So you might end up having
a bit of trouble falling asleep.
So,
to avoid this insomnia,
it is advised to stop drinking coffee
at least 6 hours,
before going to bed.
Earlier,
it's even better.
The European Medicines Agency recommends that adults should
not exceed 400,
milligrams of caffeine per day, which is equivalent to 3
filter coffees or 4 espressos.
If you follow these recommendations,
coffee
should not prevent you from sleeping.
but instead,
it will do you good. Because coffee has benefits that you
may not be aware of.
Caffeine in particular has a vasoconstrictive action. In
other words, it promotes the contraction of blood vessels.
Caffeine even helps to reduce the inflammation of blood
vessels.
That's why a coffee can sometimes relieve a migraine.
Recent studies have also shown that drinking 3 to 4 cups of
coffee a day,
would reduce the risk of myocardial infarction by 12% and
also the risk of stroke
by 8,
to 13%.
What's even more surprising is that 3 to 5 cups of coffee a
day...
would decrease the risk of developing type 2 diabetes.
But that...
it's just a hypothesis.
So,
I'm going to have another cup of coffee.
There you have it, I hope you enjoyed this video,
and that it made you want to share a good coffee with
friends.
In the meantime, feel free to like and suggest other
interesting ideas in the comments.
See you very soon
