When talking about the benefits of coffee, they first begin to consider the positive effect on the body of caffeine, the main component of the product. Scientists confirm following data:

  • prevents the removal of potassium from the body;
  • reduces the occurrence of allergic reactions;
  • protects against the effects of radiation.

  • Vidvar_z_lystja_brusnyci should limit coffee consumption to people with diagnosed cardiovascular diseases;
  • to those who have a history of hypertension, coffee is almost contraindicated;

  • the drink in question can cause physical dependence - in the event of complete refusal of its use, a person will experience headaches, weakness, fatigue and drowsiness.But this in no way equates coffee to drugs!

There are many disputes about the use of coffee by pregnant women - it used to be believed that this drink can even provoke a miscarriage.But recent studies have shown that coffee does not have any effect on the development of the fetus, it is just necessary to take into account the condition of the woman - with increased blood pressure, diagnosed kidney diseases, problems in the work of the gastrointestinal tract, it is better to refuse coffee.
