Apart from advantages there are some disadvantages also.
Teeth staining occur if not brush properly after drinking tea or coffee. Constipation is also thought to be another side effect but there is no such prove . Previous researches states that high blood pressure is also associated with caffeine consumption but still not so sure about it. The high consumption of coffee is not good during pregnancy . But still there is no proof or evidence to support the hypothesis. Thanks for sharing anyway. Good Day to you!
