Chocolate and Caffiene - Part II
Last time we started our discussion about chocolate and caffiene, after a couple of friends told me they'd heard that chocolate had caffiene.
In my scholarly way, I told them that chocolate's theobromine is more like a precursor to caffiene, but that's not actually accurate either.
I also said that the differences between caffiene and theobromine is like two different kinds of races - one a sprint, one a marathon.
This time, we'll get into a little bit more detail. So...let's get technical.
In an article entitled "Chemistry of Theobromine: Chocolate's Caffiene Relative" published on About.com, they state "Theobromine belongs to a class of alkaloid molecules knowns as methylxantines. Methylxanthines naturally occur in as many as 60 different plant species and include caffeine (the primary methylxanthine in coffee) and theophylline (the primary methylxanthine in tea)."
Let's look at some caffeine levels in some popular drinks. Information gathered is from a table put together by Clark Goble Categories.
Coming at #1 is 8 oz. of drip coffee with 145 mg or 18.13 mg/oz.
#2 - 8 oz. of brewed coffee at 107.5 mg or 13.44 mg/oz.
Others include: 8 oz. of brewed tea at 47 mg or 5.88 mg/oz.; Coca Cola Classic - 12 oz. serving at 34.5 mg or 2.83 mg/oz.
I could list more but, you can access this information online.

Chocolate and Caffiene - Part I
Recently, I had a couple of friends say they wouldn't eat chocolate in the evening because of the caffiene in it.
I snickered and said, "But there's no caffiene in chocolate!"
"There isn't?" My friend replied. A couple more friends joined in the conversation.
"I'd always heard there was!" "Yeah, I heard that too!" They said.
I said, "Theobromine is like a precursor to caffiene, but it is not caffiene!"
If you look at the chemical make-up of a caffiene molecule and a theobromine molecule, they are very similar, and they are both classified as alkaloids which have a somewhat 'stimulating' effect on the body, but the way they do that is different.
Think of the two like a race. One, caffiene, is a sprint...it's quick, and it's over. Theobromine's effect is more like a marathon - what you need over a longer period of time.
In an article posted on About.com Chemistry, "Different types of chocolate contain different amounts of theobromine. In general, theobromine levels are higher in dark chocolate (approximately 10 g/kg) than in milk chocolates (1-5 g/kg). Higher quality chocolate tends to contain more theobromine than lower quality chocolate."
Next time...more particulars...but just remember - there is no caffiene in chocolate! So don't worry about it!
