Comparing Caffeine In Soda

Count this among the questions that I never thought to ask: does house brand soda - Publix Cola, Sam's Cola, Diet Dr. Thunder, and the like - have different caffeine levels than name brands?  I'd long assumed that coffees were dosed very differently - and my assumption was correct.    One study showed that Starbucks coffee contains 56% more caffeine than the drink you buy at a local gas station or donuteria.   But it turns out that the same is true - indeed more so - when you compare name-brands like Coke to house brands.  According to Caffeine Content of Prepackaged National-Brand and Private-Label Carbonated Beverages, some house brand sodas have less than half the caffeine of name brand products.  Others have far more.  IGA Cola came in at less than 5mg of caffeine in a 12 ounce serving; Big Fizz Cola, from Rite Aid, contained 46mg.  The big names?  Coke had 33 mg, Pepsi had 39 mg, and RC had 45 mg.  The Diet versions can be quite different from their parent product; Diet Coke, for example, has 46mg.  And yes, Mountain Dew really is stronger, coming in at 55mg per can. 

If you're a caffeine addict, these small differences could matter.  A person who drinks 4 Pepsis per day taps 156 mg of caffeine.  If you're in a cash crunch and go with Piggly Wiggly Cola, you'll only rack up about 50 mg.  Your punishment for poverty?  A whopping caffeine withdrawl headache. 

For coffee drinkers, this is all child's play.  One tall cup of Starbucks drip coffee will earn you 260mg of caffeine.   Indeed, one cup of Seattle's Best decaf tested by Consumer Reports contained 29 mg of caffeine - almost the same as a Coke.

The big names? Coke had 33 mg, Pepsi had 39 mg, and RC had 45 mg

That goes a long way to explaining my preference for RC on the exceedingly rare occasions when I drink cola at all.

I would have liked a table of substances and their caffeine contents per 12 oz. And the linked reference for the sodas is just an abstract, to get any useful information you have to sign up (maybe pay something, I didn't investigate).

Caffeine is an alkaloid xanthines group, crystalline solid, white and bitter taste, which acts as a psychoactive drug and stimulating. Caffeine was discovered in 1819 by German chemist Friedrich Ferdinand Runge: it was he who coined the term Koffein, a chemical compound in coffee, which would subsequently into Spanish as caffeine. Caffeine is also part of the complex chemical mixtures and insoluble guaranine (found in the guarana), mateína (found in the material) and protein (found in tea), all of which also contain some additional alkaloids as cardiac stimulants theophylline and theobromine, and often other chemical compounds such as polyphenols, which can form insoluble complexes with caffeine.

I don't know if some sodas have more or less caffeine than other ones the point is that's very harmful for our health, I've read books which says that those beverages can distroy a tack in just two hours, that's something that makes us think about it.
