JVTech News Water is a very healthy drink. But Harvard researchers have discovered another that’s just as important: coffee

Coffee, a real surprising alternative to water?

Water is undoubtedly an essential beverage, often considered the healthiest.

However, Harvard researchers believe there are other equally beneficial alternatives. Nutrition Source, a site of the Harvard University School of Public Health’s Department of Nutrition dedicated to providing quality information on diet and nutrition, offers two surprising options: coffee and tea.

Coffee, often associated with prejudices about its effects on health, is the subject of a nice re-evaluation.

According to researchers, consumption of 3 to 5 standard cups of coffee per day is consistently associated with a reduced risk of several chronic diseases.

. Contrary to popular belief, caffeine does not increase the risk of cardiovascular disease or cancer. In fact, coffee offers many benefits.

In addition to stimulating the brain and fighting drowsiness by blocking the action of adenosine, a neuromodulator with sedative effects, coffee improves executive memory, focus and concentration. It promotes planning and monitoring of actions, while speeding up reaction time. In essence, coffee is not just a beverage, it is a veritable source of possibilities for mental and cognitive well-being.

However, it is important to note that coffee is not a panacea for everyone. Some individuals may be sensitive to caffeine, experiencing symptoms such as nervousness, anxiety or insomnia. Likewise, it is not recommended for those who have difficulty controlling their blood pressure. Despite these reservations, coffee is a surprisingly healthy option, providing a great alternative to water.

And then tea?

Besides coffee, tea is emerging as an alternative to be seriously considered. Although tea has sometimes been criticized, most notably by the WHO in 2016 which linked tea consumption to an increased risk of cancer, it is important to clarify that this warning was linked to the practice of drinking tea at extremely high temperatures.

So the problem lies more in the temperature of the tea than the drink itself. Whether black, green, oolong or white tea, as well as caffeine-free herbal infusions, tea offers a range of health benefits.

Observational studies have shown that drinking 2 to 3 cups of tea reduces the risk of “premature death, heart disease, stroke, or type 2 diabetes.” Although not necessarily a correlation, these results provide an interesting indication of the positive effects of tea on health.

What makes these two drinks particularly beneficial is not only their intrinsic value, but also what they replace.. By promoting better hydration and reducing thirst, regular consumption of water, tea or coffee may encourage people to choose other less healthy beverages, whether due to sugar or mineral content. Alcohol.
