Java alertness a myth ?
So say British researchers:
That morning latte or espresso may not be the pick-me-up people think it is, a study has revealed. University of Bristol researchers say the caffeine eases withdrawal symptoms which build up overnight, but does not make people more alert than normal.
The work, presented to the British Nutrition Foundation conference, showed only people who have avoided coffee for a while will get a buzz from caffeine.
Professor Peter Rogers, a biological psychologist who led the research, told the BBC: "We do feel a boost from caffeine in the morning, but that’s probably due to a reversal of the withdrawal symptoms.
"That alertness you feel is you getting back to normal, rather than to an above normal level.
"That morning boost is what people think is useful about caffeine, but if that doesn’t happen, maybe it’s not that useful after all."
This is something I have suspected for a while, even though I am one those who needs a cup every weekday morning. However, I enjoy the morning brew more for the flavor of recently roasted, freshly ground, black drip/french press coffee (the best way to consume the stuff). Also it counterbalances nicely the breakfast milk and cereal .
Of course, the people who sell the stuff aren’t buying into this research:
Zoe Wheeldon, of the British Coffee Association, said the research was interesting.
But she added: "There are two sides to the debate and a wealth of scientific evidence suggests that moderate coffee consumption of four to five cups per day is perfectly safe for the general population and does have a beneficial effect on alertness and performance even in regular coffee drinkers."
Ok, I like coffee – but four to five cups is "moderate" !?
