In the case of coffee, scientific evidence has shown its protective effect, putting an end to numerous hoaxes that questioned the benefits of this substance. Of course, Drinking too many cups can lead to a caffeine overdose and breach, therefore, the rule of just measure.

“Caffeine is a component that produces a stimulating effect on the nervous system because blocks the receptors of the molecules that induce us to a state of sleep“, Explain paula hinke, member of the Food Education Commission of the Official College of Dietitians-Nutritionists of the Valencian Community (CODiNuCoVa). For this reason, the specialist points out that, in the event of an excess of this substance, it produces “a state of nervous agitation that our brain cannot regulate as it normally would”.

As to the specific amount of caffeine that defines an overdose, it will depend on individual tolerance. However, as he points out Naiara Carreteropresident of the Professional Association of Dietitians-Nutritionists of Castilla y León (CODINUCyL), the European Food Safety Authority (EFSA) has established some references on the safe intake of caffeine.

Regarding repeated vomiting, the nutritionist indicates that “an electrolyte imbalance may occur, since a significant amount of water and minerals are lost, such as potassium, which are essential for the functioning of our body.” At this point, she emphasizes that “the only thing we can do in a serious case is try to alleviate the symptoms until our body metabolizes the excess caffeine.”

Stopping caffeine suddenly is not recommended because, as already indicated, it can trigger withdrawal symptoms. “If we are used to drinking caffeinated drinks every day, the ideal is always to gradually reduce. Opting for decaffeinated versions also helps,” Hinke says, though he reminds that these drinks actually contain caffeine, too, just less.
