Caffeine and Your Body

By Dr. Beth Quintana, N.D.
Throughout the world, caffeine is the most widely consumed legal psychoactive stimulant. It’s estimated that about 90 percent of adults consume caffeine daily. Here in the Pacific Northwest, caffeine consumption can be a religious experience. But have you ever wondered how much is too much? And what effects does it have on the body anyway?
The amount of caffeine an individual can tolerate varies. Body weight, metabolism and level of sensitivity will impact how your body reacts to caffeine. Moderation is the key. For some, too much caffeine can cause sleeplessness, anxiety, upset stomach, and headaches.
It’s also been found that caffeine can provide numerous health benefits as well. Studies have shown that caffeine increases alertness, metabolism and athletic endurance, and that it improves mood. Other studies have shown moderate amounts of caffeine to be safe and help to prevent some diseases, including cancer.
So just how much is a moderate amount of caffeine? About 200 to 300 mg per day, or about two to three cups of coffee, says the U.S. Food Administration and the American Medical. This amount has been determined to be to be generally safe for most adults.
Levels of Intake:
Low intake is 100 to 200 mg per day
Moderate is 200 to 300 mg per day
High intake is above 400 mg per day
Extremely high amounts such as 80 to 100 cups of coffee can be toxic
