I prefer tea to coffee, but I've heard that tea has as much caffeine as coffee. Is that true? I make about two cups of tea from one tea bag. I've been reading a lot about caffeine lately. The caffeine content of a tea bag brewed for five minutes is about 47 milligrams for...

I am going to be in a 100-mile bike race in July and have heard that some caffeine may help me last longer and go faster. Is that true? If so, how much caffeine should I take? Sports researchers have studied the positive effects of small amounts of caffeine on athletes by reducing fatigue. Caffeine-containing...

In your section on caffeine, you recommend that to reduce intake to limit a cup of coffee to one a meal. Does caffeine affect the absorption of certain vitamins or minerals like iron? I could be way off, but I thought that it was better not to have caffeine with meals. Please set me straight...

I've recently been diagnosed with a mild case of mitral valve prolapse. My doctor prescribed 50 milligrams of beta-blockers and a caffeine-free diet. The only things she mentioned to avoid were coffee, tea, caffeinated sodas and anything containing chocolate. Are there other foods that contain caffeine or is my list above complete? Thank you....
