Caffeine is a stimulant that can be mildly addictive. Caffeine is found in the seeds, nuts or leaves of some plants in South America and East Asia. The most common source of caffeine is the coffee bean, which is actually a seed.
Products like coffee and chocolate naturally have high caffeine content. Other popular products, however, require the caffeine to be extracted from the plant by steeping in water. This process is called infusion.
Caffeine is officially categorized by the Food and Drug Administration as a stimulant that is "generally recognized as safe," or GRAS. However, there have been a number of studies that have revealed probable connections between caffeine consumption and negative health effects, especially cardiovascular health.
However, negative impacts on health typically only occur from high dosages of the stimulant. For example, one study found that consuming three cups of coffee per day made cardiovascular diseases, such as coronary artery disease and strokes, less likely, while consuming more than five cups of coffee per day made them more likely to occur.Learn more about Nutritional Content
