Moderate coffee consumption promotes communication between neurons
Coffee goes far beyond just a social habit to cultivate and science has shown that the way the drink is consumed can completely change its effects on the body, especially when it arrives in the cup without sugar or sweeteners.
A recent study from Johns Hopkins University, published in the scientific journal Nature Neuroscience, investigated how black coffee affects the body and brain. The results indicate that regular consumption of this drink, in its most natural form, is associated with cellular protection mechanisms and important stimuli for neuronal functioning.
The research, carried out in Baltimore, USA, analyzed the relationship between caffeine and cognitive performance. According to scientists, moderate coffee consumption promotes communication between neurons, strengthening the brain networks responsible for attention, reasoning and mental agility.
More than a resource to fight against sleep, coffee appears to be an ally for brain health. Researchers observed positive effects on the hippocampus, an area directly linked to memory and learning, suggesting that this habit can help keep the mind active over time.
Impact on metabolism and body weight
From a metabolic point of view, sugar-free coffee stands out for being a drink with very low caloric value and no fat, characteristics that promote weight control.
The study highlights two main effects: the increase in thermogenesis, a process that increases the body’s energy expenditure, and the acceleration of basal metabolism, allowing the body to use energy more efficiently.
Rich in antioxidants, coffee also plays an important role in protecting cells. These compounds help fight free radicals, reducing oxidative stress and contributing to tissue preservation.
In addition, the analyzed data indicate benefits for the cardiovascular system. Regular consumption of this drink can help prevent plaque buildup in the arteries, an essential factor in reducing the risk of heart disease and circulatory problems.
Oral health ally
The drink also contains substances that can help inhibit the occurrence of cavities. This effect, however, only occurs when coffee is ingested pure. The addition of sugar or artificial sweeteners cancels the protective action and promotes damage to tooth enamel.
