Below we list the advantages and disadvantages of coffee, according to the latest scientific data. Meanwhile, it should be highlighted that the opinions of different scientists often contradict each other, and it can be reasoned by the fact that different people react differently to the same factor.

Harms of coffee
Coffee overuse causes depression
You know how easy it is to wake up after having some sips of coffee, as the coffee is able to “awaken’ the nervous system and promote the work of our brain. In spite of the fact that this feature of coffee seems to be positive, it should be noted, in case of overusing, coffee can negatively affect the nervous system. So when overused, coffee can provoke insomnia, exhaustion, irritability, tachycardia, aggression and psychosis.
Coffee may harm pregnant women
The harm of coffee for pregnant women has been scientifically proven. The fact is, caffeine may pass through the placenta to the baby and has the same impacts as on mother. Thus, in case a pregnant woman drinks more than 4 cups of coffee a day, the risk of abortion increases by 30 percent. With more moderate dose of coffee consumption, the percentage of risk is rapidly falling.
Coffee harms the cardiovascular system.
Consumption of caffeine causes increase of blood pressure and heartbeat and such an effect can be rather dangerous for those who suffer from hypertension. To prevent coffee damage to the heart and blood vessels, people with cardiovascular diseases are generally not recommended to drink coffee.
Damage to micronutrients of the body
Coffee washes away a number of microelements and vitamins from the body, including, but not limited to calcium, magnesium, and sodium. This negative impact is even increased in case coffee is consumed immediately after eating.

Its influence depends on the characteristics of the body and the amount of coffee consumed. A healthy person should drink 2 to 3 cups of coffee per day and there will be no harm. But those who have a hypertension disease of blood vessels, various diseases of gastrointestinal tract or insomnia should restrict their coffee consumption.
