It really depends on the quantity of caffeine you ingest, and whether it interacts with other substances such as drugs and alcohol. It also depends on your pre-existing heart conditions.
The recent claims about a few teenagers who died after drinking a large quantity of Energy Drinks loaded with caffeine may make people think that caffeine is a killer. If you have been reading my articles, “no caffeine” is one of my “Eight Commandments” in my anti-yeast nutritional program (see my yeast-free cookbook: Healthy and Tasty: Dr. J’s Anti-Yeast Cooking).
Caffeine is a stimulant. A large quantity of caffeine interacting with drugs, and/or alcohol, and pre-existing heart conditions, can cause arrhythmia (irregular heart bits), and possible death.
