Here are the most common sources of caffeine for Americans:
- Coffee - Contains about 100mg per 8-ounce cup though most coffee drinkers will use a larger cup (12-16 ounces) for their daily brew.
- Black Tea - Contains 50mg per 8-ounce cup. Green Tea contains 25mg.
- Caffeinated Sodas - Coke, Pepsi, and others contain 40-50mg per 12-ounce can.
- Super-Caffeinated Colas - Jolt contains 70mg per 12-ounce can.
- Energy Drinks - Red Bull and RockStar contain about 80mg per 8 ounce can.
- Milk Chocolate - Contains 6 mg/ounce.
- OTC Medications - Anacin contains 32mg/tablet. Extra Strength Excedrin contains 65mg/tablet. NoDoz and Vivarin each contain 200mg/tablet.
Caffeine has long been considered an unhealthy lifestyle choice. Caffeine's negative effects on the nervous system and how it increases anxiety, heart rate and sleepless nights have always been a concern. But recently coffee and caffeine have been shown to have some significant medical benefits.
After more than 10,000 scientific studies over the past 30 years the findings indicate that people who drink one to three cups of coffee a day are less likely to contract diabetes, develop Parkinson's disease, or have gallstones. Additionally, coffee reduces the risk of colon cancer and cirrhosis of the liver. Some of these findings may be due to the health benefits of the coffee bean itself, but most can be linked directly to caffeine. Coffee has also been shown to be beneficial in asthma (caffeine is a bronchodilator), stopping headaches (a vasoconstrictor) and improving mood (releases dopamine), all due to the systemic actions of caffeine.
In spite of these beneficial effects, it is still recommended to consume caffeine in moderation. Enjoy your day cup(s) of joe - or my favorite, Diet Pepsi® - but remember that too much of a good thing is not always better. Everything in moderation, nothing to excess.
