No. See post #12, above.

It talks about slow metabolizer but not fast metabolizer. Did I miss something? I would equate this to alcohol metabolic rate. Some drinkers metabolize it faster than others (gender dependent as well). Those with faster rate would sober up faster too.

Based on my own experience and that of people I personally know who get different reaction from coffee, I don't think the effects of caffeine linger on for the "same" duration between slow vs fast caffeine metabolizers.

...there's currently no link in terms of those types of physiological responses to caffeine and speed of metabolism."
Caffeine doesn't work like alcohol. False analogy.

Thanks for the summary. I just could not get through that video with the weird phrasing of the narrator.

He has an irritating manner of speaking, doesn't he? Probably he should get Peter Coyote to do the narrating. But the content is worth putting up with him.

I watched another of his videos, about blueberries. My wife figures they have to have value since they are so *purple*. What other foods are like that? Not very scientific (she is a scientist) but I sort of had to agree with her, conditionally. Anyway, it was nice to hear some of the evidence. It's not easy scouring the web and reading journal articles, assuming you even have access to them. And can understand them. Neither are low bars. Anyway, I've got this guy's channel bookmarked now.

Just note that he is very anti-meat. Very.

Thanks for the warning. Although it wouldn't surprise me that if one looked carefully at the evidence it would turn out that meat really isn't all that great for human health or the environment, never mind the question of animal cruelty.

I'm more interested in coffee. Should I have that third cup?

As a carnivore I very strongly disagree with that opinion! (grin) Plants have lots of toxins that want to kill you since they cant run away and don't want to be eaten. You can be very healthy, eliminate many health issues on meat and saturated fat - no plants, no carbs, no fiber!

Back on topic I have the slow caffeine metabolizing gene so am down to under 10g regular beans/day. Beware of studies - even RCT's that have small sample sizes and short duration. P-values near 0.05 also indicate weak or no statistical significance. I have heard that some people have a 1/2 life for caffeine that is days, not hours.

I had coffee made from 54g of beans yesterday. Today it's 36g but I'm thinking about another cup. It will feel fine today if I drink another but maybe it's a bad idea. Humans aren't well wired for avoiding long term issues that don't bite us in the short term.



I think I'm going to pull another shot.

Do you get jitters from drinking more than usual, say 2 cups or more of coffee in a hour?
