My doctor advised me to avoid caffeine because I have heart palpitations. Caffeine is a stimulant that is found naturally in certain plants, and it can be synthetically produced. It promotes wakefulness and increases mental activity. It also acts as a diuretic, increasing urination.
Caffeine is consumed in large quantities around the world.
The most reliable way to find out if something contains caffeine is to read the nutritional label. If you have any doubts about what foods to avoid, talk to your doctor to find out what is right for you. Always consult your own doctor about any opinions or recommendations with respect to your symptoms or medical condition. Beth Israel Deaconess Medical Center .
