Caffeine yes

or

no?

Or what is the same: is it good to drink coffee?

The question has controversial answers, depending on who answers it.

For some it is unthinkable to start the day without a generous

cup of

well-charged coffee, the basic formula to activate the brain and clear up when the alarm clock forces you to leave bed.

For others, nothing worse due to

caffeine , a

demonized

substance

for considering it addictive and related to sleep disturbances,

hypertension

and even stomach problems.

But what does

science

say about it?

Very different things.

In 2021, what was the largest

study

to date on the subject claimed that

three cups

of coffee a day was associated with a lower risk of stroke and fatal heart disease.

''Regular coffee consumption is

safe

, as even a

high daily intake

has not been associated with adverse cardiovascular outcomes after 10 to 15 years of follow-up,'' explained Judit Simon, MD, of the Heart and Vascular Center, Semmelweis. University of Budapest (Hungary) at the European Society of Cardiology Congress that year.

When to drink coffee

Now, another

scientific study

points out when is the time of day when taking it will bring more

benefits

and less of its possible negative effects.

This is research published in the scientific journal British Journal of Nutrition, which has analyzed what happens in the body when we drink strong coffee in the morning as soon as we get

up

and then

have breakfast

to recharge our batteries.

According to the lead

researcher

of this study, Harry Smith, from the Department of Health at the University of Bath, starting the day after a poor night's sleep

with

strong

coffee

had a

negative

effect on glucose metabolism for half of the patients. trial participants.

After a sleepless night or in which little sleep has been received, this habitual gesture, far from helping the body, puts it in trouble because that cup of coffee shoots up blood

glucose

levels by up to 50% compared to those who

avoid

that freshly woken coffee or

postpone

it for a while until after

breakfast

.

"Blood sugar

control

is affected when the first thing our bodies come in contact with is coffee

,

especially after a

disrupted night's sleep

," said James Betts, co-director of the Center for Nutrition, Exercise and Metabolism at the

University of Bath

during the presentation of the study.

According to these experts, different

investigations

have already shown the relationship between

caffeine and

insulin

resistance

, a link that would explain the results of their trial.

And that is even greater when you have not slept well.

"We still have a lot to learn about the effects of

sleep

on our

metabolism

," says

Harrys

, but the truth, according to his report, is that the combination of coffee and insomnia causes the body to

not be able to process the

sugar

present in the food that is ingested.

So how do we reap the benefits of coffee?

Easy, clarifies James Betts: "

Eating breakfast

first and drinking coffee later, later, if we feel we still need it."

And how long do you have to

wait

?

It is something that the study does not reveal, and that will depend on the

metabolism

of each person.

5 myths of a good coffee

SHUTTERSTOCK

True or false?

There are many myths around coffee, some completely far from reality.

An expert in the field,

Adelino Cardoso,

Roasting

Coordinator

of one of the main coffee companies, Delta, analyzes the five most widespread.

  • Coffee is addictive.

    How many times have we heard someone say that they cannot function without coffee?

    It's understandable: caffeine is a stimulant that causes the brain to release dopamine, a neurotransmitter that helps improve mood and concentration, as well as reduce fatigue.

    But unlike other stimulants, caffeine, when consumed in moderate doses, does not produce a surge of dopamine sufficient to activate the brain's reward circuitry or the sensations of pleasure necessary to create an addiction, which is known as associative learning and that is at the base of chemical dependency.

    Coffee may be habit forming, but it can hardly be considered addictive.

  • Drinking coffee prevents sleep.

    Suppose we are talking about the recommended dose of caffeine for adults, about 400 mg/day or three coffees a day, since caffeine is also present in other products such as tea (theine), chocolate, soft drinks, and energy drinks. .

    When you drink coffee, the body quickly absorbs the caffeine.

    Upon entering the bloodstream, it blocks adenosine receptors, a chemical produced by the brain when we are awake and responsible for making us sleepy when our body calls for rest.

    This lock is what allows coffee drinkers to be more alert and vigilant.

    The time it takes for caffeine to leave the body varies from person to person, which is why some can drink coffee after dinner and sleep peacefully.

    But, on average, its effect lasts between 4 and 6 hours,

  • Children are not allowed to drink coffee.

    It is much easier to find someone who is willing to give a child sugary and processed items than coffee.

    To say the least, it's a controversial choice, because in addition to the harmful effects of sugar, many soft drinks and chocolates contain caffeine in their composition.

    There is also the old myth that coffee affects the growth of children, which has no scientific support.

    Should children be allowed to drink coffee?

    No. But it is possible to give it to them.

    According to the European Food Safety Authority, children and adolescents can consume about 3 mg of caffeine per kilo of weight.

    This means that a 10-year-old with an average weight (around 30 kilos) is capable of consuming the equivalent of a cup of coffee a day.

    With or without milk, but always, preferably, without sugar.

  • 'Unbeginning' coffee is cleaner.

    Americano, short, with cold milk, cut, double, alone, with hot milk, bonbon..., there are many ways to order coffee.

    Also the so-called 'without beginning', when it is allowed to run for a few seconds before putting the cup in to avoid possible remains of the machine.

    With a well tuned and in good condition it is impossible for it to happen.

    The reason to ask for a coffee without ground is another: the grounds contain the highest concentration of caffeine;

    By placing the cup under the spout only after the initial flow of coffee, the barista ensures that a weaker one will be served.

  • Long coffee is weaker.

    Although a short coffee has, on average, about 10 milligrams less caffeine than a long one, it contains more concentrated caffeine in relation to the total volume.

    This happens because in the coffee extraction process and the caffeine concentration is not linear.

    When the water begins to pass under pressure through the ground coffee, it initially picks up the highest concentration of flavors and caffeine.

    As more water passes through, these features are diluted.
