The drink has many nutritional qualities. But there are those who avoid the characteristic that has to speed up the heart. Now Brazilian researchers are studying coffee that is already born without caffeine.

It is present in other beverages and foods, such as teas and chocolate.
However, caffeine is essentially linked to coffee.
The substance is an appetite suppressant and a stimulant.
But it also has a downside.
It can cause anxiety, insomnia, intestinal disorders, sweating and accelerate the heartbeat.
Finding decaffeinated coffees is easy.
It is difficult to remove caffeine from coffee beans.
This is a very chemical process - usually methylene chloride or ethyl acetate.
In the end, decaf has up to 0.10% caffeine (a traditional one has more than 1%).
Now Brazil is leading research to produce naturally decaffeinated coffee.
Not exactly now, since research has been conducted for 20 years.
The work is from the Campinas Agronomic Institute (IAC), which aims to develop almost zero caffeine coffee since its cultivation.
This way, the fruit would not have to go through the chemical bath.
We must still wait to find the product in the market.
Between planting and the birth of the first fruits it takes six years.
And only after seven generations of crosses can it be said that the plant already has an established genetic uniformity.
With cuts in official funds (the IAC is the São Paulo government agency), delays are expected.
Industry interest is expected to accelerate research development.
After all, Brazil is currently the most coffee-consuming country in the world - since 2014, it has surpassed the United States.
Each Brazilian drinks 2.3 cups of coffee / day, (839 coffees a year, according to consultancy Euromonitor).
But problems with insomnia or gastritis can lead the consumer to a change of habit.
In this scenario, decaf versions appear as an option.
The Brazilian version, natural, still promises to keep the aroma of the drink.
