The Fun Guy writes "The Institute of Food Technologists summarizes some recent research on food. All things considering, it should settle some arguments among geeks about the caffination of beverages. 'Caffeine is a well-known stimulant added as an ingredient to various carbonated soft drinks, but which drink contains the most, and how can consumers know? A study in the Journal of Food Science used high-performance liquid chromatography to analyze the caffeine contents of 56 national-brand and 75 private-label store brand carbonated beverages. Caffeine contents ranged from 4.9 mg/12 oz (IGA Cola) to 74 mg/12 oz (Vault Zero). Some of the more common national-brand carbonated beverages analyzed in this study were Coca-Cola (33.9 mg/12 oz), Diet Coke (46.3 mg/12 oz), Pepsi (38.9 mg/12 oz), Diet Pepsi (36.7 mg/12 oz), Dr Pepper (42.6 mg/12 oz), Diet Dr Pepper (44.1 mg/12 oz), Mountain Dew (54.8 mg/12 oz), and Diet Mountain Dew (55.2 mg/12 oz). The authors found that store-brand beverages generally contained less caffeine, and they also suggest that consumers would benefit from having the actual caffeine content labeled on the beverage.'"
