Tea? Coffee?

Recent research shows that
(i) caffeine prevents and even reverses the effects of Alzheimers, and
(ii) tea consumption reduces the risk of Parkinsons

So do I drink coffee and get Parkinsons or tea and get Alzheimers?

I guess tea has a little caffeine, so I could drink like 15 cups a day.

Who knows - if I stop putting milk in it, all that peeing might even help with kidney stones. Or then again, maybe it will power my car.

It is fairly simple, a cappuccino in the morning and after lunch, and the rest of the day drink tea.

Tea can have more caffeine than you think, depending on the brand and how it's prepared. A cup of brewed, non-decaffeinated tea can have more caffeine per drop than cola, and a significant percentage of the caffeine of coffee.

It's a little hard to quantify because tea and coffee aren't standardized, but here are some figures:
- Coke Classic has 2.88 mg of caffeine per ounce
- Regular Pepsi has 3.17 mg/oz
- Diet Pepsi has 3 mg/oz
- Diet Coke has 3.75 mg/oz
- Red Bull has 9.64 mg/oz
- Coffee depends on what type, what brand, and how it is brewed. (Instant is less caffeinated than drip-brewed, and so on.) Starbucks provides a good baseline: in general, non-decaffeinated Starbucks coffees range from 6 to 22 mg/oz, depending on the drink; their bottled frappucinos (which are a convenient reference point for coffee because the bottles are widely available and reasonably uniform) have 9.47 mg/oz
- Tea, like coffee, varies by how it is prepared (how long it steeps, for tea) and what sort of tea it is; green tea generally has less than black tea, and the tea in American tea bags tends to be less caffeinated than imported varieties, but the range is something like 1.5 to 7 mg/oz. Snapple Tea (to take another standardized reference point) is 2.62 mg/oz

So a very strong tea -- up in the 7 mg/oz range -- could have more caffeine than a weak (but still caffeinated) coffee from Starbucks. It looks like most of the commercial bottled tea sold in the U.S. is between 2 and 3 mg/oz

There are lots of sources for this information online if you look around. The one I took these specific numbers from is at

It seems my attempt at humor didn't come over. Oh well.

I don't think it can be the caffeine that has the anti-Parkinson's effect. This is only anecdotal, but my father was told by his doctor to cut back on his coffee drinking, as it was causing tremors due to the amount he used. Now he is well into his 3rd decade of Parkinson's. Mind you, who knows what would have happened if he had kept drinking the coffee.
