Waiting outside the doctor's surgery yesterday and trying not to breathe in all the coughs and sneezes, I scanned the leaflet rack in search of some amusement. Amongst all the breastfeeding stuff and the many NHS Stop Smoking pamphlets, my eyes alighted on an ochre-hued A5 foldout entitled "Coffee And Your Health". Now, I'm very fond of a black coffee with my smoke and have been for as long as I can remember. Further, the prospect of getting up at the crack of noon without the dark aroma of something Columbian to stir me into consciousness remains unthinkable. This caffeine fix though, is one addiction I've been forced to keep in check of late...
A few years back, I had cause to be ambulanced into hospital a number of times, suffering unbearable abdominal pains. These turned out to be caused by nothing more serious than gallstones but, even so, these episodes showed me some of the worst physical pain I've ever endured: a cramping, doubled-up agony of knife-twisting, nerve-jangling, screaming pain [oh, yes!] with severe nausea and vomiting and spread over ten hours or more each time. One year, two C.T. scans and an endoscopy* later, I was given the all-clear with regard to the scary stuff but warned that I have a predisposition for building up these mineral deposits around the kidneys and that each time they cause a blockage, there is risk of kidney damage. My lifestyle was analysed and the culprits soon identified, in that caffeinated coffee and Coca-Cola were forming over two-thirds of my daily fluid intake. In particular, I was advised to cap my caffeinated drink consumption at less than 50% of my overall fluid intake. Sticking to this advice, I weaned myself off Coca Cola [harder than you may think, but worth it] and substituted orange juice for some of the coffee. Five years later, I'm happy to report that I'm fighting fit and pissing like a horse. [Oh, and the ear-infection's clearing up nicely, thanks.]
So what did I expect from an NHS leaflet about coffee? To be honest, I think I wanted a nostalgia trip and a bit of flattery. A restatement of the risks of over-consumption, a warning about the addictiveness of caffeine, a description in print of the pain I had suffered to back up one very sympathetic doctor's assessment of the mobile gallstone as being "one of the most acute pains it is possible to experience".
What I did not expect to be reading in the section "Facts About Coffee" were a load of industry statistics about it taking 42 beans to make an espresso and about the 85% of UK consumers' preference for adding milk.
"The aim of this leaflet
" runs the introduction "is to provide factual information about coffee, caffeine and your health." "... there can often be confusion about whether coffee and caffeine is healthy and people sometimes worry about how many cups can be drunk a day and how it affects the body. In fact, there is no need to worry about drinking coffee, as long as you stick to the daily amounts recommended by
experts." [my emphasis] "It may even have some benefits on your health." We are informed that, "for the majority of people", this safe moderate consumption is 4 to 5 cups per day. Beyond pregnant women or "those trying to conceive" being advised to cut this back to "3 or 4 cups per day", there is no mention of who else may belong to that minority for whom a daily 400mg of caffeine could cause problems and not the tinkliest inkling of just what these problems may actually entail.
Reading on, I find that the British Dietetic Association and the British Nutritional Foundation both agree coffee can count towards the "6 to 8 cups of assorted fluids you should drink every day to keep your body hydrated". Oh, really? A 75% intake of caffeinated fluid's okay then, is it? "Although caffeine is a mild diuretic..." I looked up, wondering if there was anyone in the waiting room likely to know what "diuretic" meant. Hazarding the correct guess of "it makes you go", I carried on: "Although caffeine is a mild diuretic, drinking a moderate amount of coffee daily is unlikely to have a diuretic effect on the body." Oh, that's cool then.
Smelling a starbuck, I went to the small print and found this leaflet to be the work of the "British Coffee Association". So no surprise then, that the penultimate pane is entitled "Coffee and Health Benefits". It comprises such gems as "Studies have implied that coffee contains high levels of antioxidants..." Studies have
implied, indeed! Oh, and "Some research has suggested..." [two walloping great caveats for the price of none] that regular coffee consumption "...could help protect against diseases including liver cancer, type 11 [two?] diabetes, Alzheimer's disease and Parkinson's disease."
Alzheimer's and Parkinson's? Surely not, for these are the very two deadly degenerative diseases which
some studies have suggested are considerably rarer in smokers than in non-smokers. Actually, the evidence here is stronger than just a suggestion of a protective effect; some studies
demonstrated a 50% lowering of risk for smokers. And some
suggestion of knock-on benefits for their passive-smoking dependents as well, but I won't dwell on those.
It would be interesting to know which studies are being quoted and interpreted by the B.C.A., but they're not telling. I'd like to know if the studies' methodology checked the smoking habits of the sample and how the stats stack up when tobacco consumption is excluded. You know, credit where credit's due and all that, an' I don't think it's
moral for the burgeoning coffee capitalists to steal health-benefits from an increasingly hard-pressed tobacco industry.
Is it right for the NHS to take money from and promote the products of a not-exactly-blameless industry selling an addictive product at a high price and where habitual consumption of the product has, at best, mixed health implications?
*endoscopy A visual examination probing the innards of the bladder. The bad news for a chap is that the roving camera's port of entry has to be the penile tube. What's more, the bladder must be kept inflated during the examination and this is achieved by forcing water out of the hose carrying the camera. Not to worry, I thought, in the weeks preceding the event; the white heat of technology will have created something of such fibre-optically filigree'd slenderness, I'll barely notice it going in. Look at the flashing lights and white coats instead and don't think about what may or may not be going on, you know, ...
down there. Think of England.
"This might sting a bit".
I was quite calm until I saw it. Fibre-optics? Try garage-airline with a mini-maglite on the end. And it's foaming.
But it went in okay with a dab of gel.
Ladies!
