Recent scientific research is changing the perception of coffee, one of the most popular beverages in the world.Although it was once viewed with caution because of the risk of cardiovascular disease, today moderate alcohol consumption is associated with greater protection of the cardiovascular system.Evidence shows that regular drinking reduces the risk of heart disease, stroke and heart failure.
This paradigm shift is the result of large studies that have developed the consumption habits of hundreds of thousands of people over several years.The results challenge the long-standing stigma and position of coffee not only as a stimulant, but also as a rich source of beneficial bioactive compounds.The key to their usefulness, according to experts, is the amount and time of consumption.
More than just a drink, coffee contains over a thousand chemicals that interact with the body in complex ways.Caffeine is only one of these components, and science is now delving deeper into the effects of other ingredients such as antioxidants and polyphenols, which play an important role in protecting cells and improving vascular function, contributing to a more robust cardiovascular health.
The science of legumes and how caffeine works in the body
Coffee's reputation as a heart supporter is based on its complex chemical structure, which goes beyond caffeine.The drink is one of the main sources of antioxidants in the Western diet, especially compounds known as polyphenols such as chlorogenic acid.Essas ingredients play an important role in combating oxidative stress, a cellular process that contributes to the development of chronic diseases, including aging and heart disease.Oxidative stress damages the artery walls, making them harder and There is a risk of the formation of atherosclerotic plaques, which can lead to heart attacks and strokes.By neutralizing free radicals, coffee's antioxidants help maintain the integrity and flexibility of blood vessels, improve blood circulation and reduce the burden on the heart.Alem In addition, coffee has anti-inflammatory properties that are important for vascular health, since chronic inflammation is a known risk factor for heart disease.The combination of these effects is good Contributing to endothelial function, which is the ability of the inner layer of vessels to properly contract and relax, to regulate blood flow and blood pressure.
New discoveries about an old acquaintance
The idea that coffee harms the heart has been the consensus view for decades, with medical advice focused on limiting coffee consumption to prevent arrhythmias or spikes in blood pressure.Hey, science offers a more nuanced and positive perspective.Estudos' solid studies show that in moderate doses the drink is not only safe but may also be beneficial for most people.
Research published in internationally renowned cardiology journalsIt analyzed data from thousands of individuals.And they found a clear association between moderate coffee consumption and a reduction in serious cardiovascular events.One study found that people who drank coffee in the morning had a significantly lower risk of dying from heart disease.and challenge enduring stigmas
The benefits extend beyond caffeine, including more than a thousand biotic compounds with anti-inflammatory and antioxidant properties.SES elements help improve artery health and may reduce the build-up of fatty plaque, reducing the risk of heart attack and stroke.
Why will your coffee time change?
The moment you drink coffee can directly affect its effect on the body.A recent study by Pesquisas shows that drinking coffee in the early hours of the day is more consistent with the circadian cycle, the body clock that controls many body functions, including sleep and wakefulness.
Drinking in the morning takes advantage of the body's natural alertness without significantly interfering with production of the nighttime sleep hormone melatonin.Caffeine consumption in the late afternoon or at night can disrupt this cycle, impairing the quality of rest.
Inadequate sleep is an independent risk factor for cardiovascular problems, as it can lead to high blood pressure, systemic inflammation, and hormonal imbalance.In order to maximize the benefits of coffee and minimize the possible harms, it is recommended to concentrate coffee consumption in the morning.
Therefore, the strategy is not only how much you drink, but also when.Priorizar's morning coffee allows the bioactive compounds to act positively while the body prepares for the day's activity, without compromising the nightly recovery necessary for heart health.
Care and recommendations for safe consumption
Despite the promising benefits, experts say moderation is the most important factor.Excessive consumption, generally defined as more than five cups a day, can negate the positive effects and even create risks such as anxiety, insomnia and palpitations, especially in people who are more sensitive to caffeine.
People with pre-existing conditions, such as uncontrolled hypertension, complex cardiac arrhythmias or gastritis, should seek medical advice before incorporating coffee into their routine or increasing consumption.The response to caffeine is individual and can vary genetically, making professional advice essential for these groups.
The effect of the type of preparation on health
The way coffee is prepared also affects its effects on cardiovascular health.Studies show that filtered coffee, whether through a paper or cloth filter, is the safest choice, as the filter retains compounds like cafestol and cahoots.Essences, which are found in large amounts in unfiltered coffee, such as French press or Turkish coffee, can raise levels of harmful cholesterol (LDL).
Additionally, it is important to pay attention to supplements.Filled with processed foods, sugar, syrups and ice cream, coffee shops turn healthful drinks into sources of empty calories and saturated fat, completely neutralizing the benefits of probiotic compounds in grains and contributing to increased cardiovascular risk.
Alliance for a Balanced Lifestyle
New scientific discoveries are encouraging more people to strategically incorporate coffee into their daily routine, always following recommendations for quantity and timing.However, it is important to understand that the drink does not act as a stand-alone or magic solution for heart health.
The greatest benefits of coffee consumption are observed when it is placed in a context of healthy habits.Isso involves a balanced diet, rich in fruit, vegetables and whole grains, regular physical activity and abstention from smoking.Coffee serves as a valid complement to this lifestyle, improving cardiovascular health, but it does not replace the fundamental pillars of well-being.
A promising future for research
Science continues to explore the various mechanisms by which coffee affects health.Current research is investigating how its compounds influence the gut microbiome and how genetic factors determine individual responses to caffeine, paving the way for increasingly personalized and effective consumption advice.
