Are coffee grounds a safe fiber to add to recipes? I enjoy the taste.

How is Caffeine measured generally in lets say a cup of coffee, is it the weight of beans, or is it the diluted volume of liquid?

I had a small stroke 2-1/2 yrs ago and the Dr.'s say a migraine caused it. The caffeine I drank for years caused me migraines throughout my life in hindsight. In years past Dr.'s just put me on large dose Tylenol and Ibuprofen taken together. Since the stroke I have cut out most of my caffeine and take prescribed drugs in combination to hopefully prevent future strokes.
I've worked with other people that drink WAY to much caffeine and I hope they don't have the problems I have to deal with the rest of my life.
One person I know would brew a pot of coffee in the morning then let it stay on the machine all day until it looked like tar then reheat it the next day.

Does your ethnicity (genetic background), height or weight make a difference on how caffeine affects us?

tea definitely does not affect me the same way as coffee, and some teas can have more caffeine depending on how long and strong you brew -- but i'm pretty sure that coffee is digested differently in my digestive system, more like solid food than liquid. pretty sure most people experience this.

Tea has less caffeine than coffee, except for Celestial Seasonings' Morning Thunder, which has more caffeine & less tannins than coffee. I can testify from experience that it's really strong.

Chocolate has a small amount of Cannabinoid. It also slows the degradation of naturally occurring Cannabinoid in the brain.
So Chocolate gives a marijuana-like high.

Is the stimulant in yerba mate (called "mateine" on the package) related to caffeine, & how? Some people say it causes wakefulness just as well as caffeine w/more focus & less jitteriness.

I recently cut my coffee amount in half two weeks ago. Not going cold turkey, but greatly reduced, yet Ive had a back ache ever since which seems related. Is this possible?

decaf has small amounts of caffeine

Mar. 21 2014 12:09 PM

espresso has less caffeine because of the volume. i shot is less volume of liquid than a normal cup of coffee

Mar. 21 2014 12:09 PM
Bill from UWS

I've heard that a shot of espresso has less caffeine than a typical cup of brewed coffee, perhaps because the pressurized steam used to make espresso doesn't extract as much caffeine. Is this true?

Also, is there any caffeine in Decaf? If so, how much?
