Caution does not hurt
Be that as it may, in the case of coffee, the rule of the golden mean applies: you should not consume more than two or three cups a day. And, despite the fact that scientists from different countries are still debating the recommended dose of the drink, special attention should be paid to the amount of coffee consumed by those who suffer from hypertension. Caffeine in beans can increase blood pressure.
If two cups of coffee can help you concentrate and invigorate, then an excess of caffeine will cause increased irritability and nervousness, reduce the elasticity of blood vessels and even increase the risk of stroke, heart attack and hypertension. For a long time it was believed that pregnant women should completely abandon coffee, but now scientists have come to the conclusion that there is no reason for this.
