The New York Times has a study by the Center for Science in the Public Interest on the health effects of caffeine. The study analyzes various claims made about caffeine, and it also offers a useful chart listing the caffeine content in typical drinks and foods. For instance, at 320 milligrams per 16 ounces, a Starbucks grande coffee has over four times the 80 milligrams of caffeine of a Red Bull.
Other findings by the Times and CSPI:
- Unless you consume more than 575 milligrams, caffeinated drinks don’t actually make you pee more.
- Coffee does not increase the risk of heart disease or cancer
- Even though it stimulates the metabolism, caffeine does not increase weight loss. It does aid exercise, however, by dulling pain and stimulating the body to burn fat instead of carbohydrates.
