Excellent Journalism.
It's a delight to come across some decent journalism. Sadly it's a rare thing these days, but I really welcome somebody taking along, hard view at what passes for policy making in this country. Much of what comes out from politicians and journalists (plus not a few comedians) is pre-digested views based on dubious research of the worst order.
Whilst on the subject of ridiculous use of statistics in the name of fashionable policies, one might want to look at what the FSA and Ofcom are up to on food and dietary standards. Recently Chris Hoy has been lambasted by some self-appointed outfit called "The Food Commission" as one of a number of sportsman promoting what they call "junk food". His crime? Well he's been putting his name to what the FSA and Food Commission define as a "high sugar" foods in the shape of Kellogs Bran Flakes. This story was picked up by Ben Goldacre's usually excellent Bad Science blog (in the microblogs) where he joined in the condemnation.
Well the facts are these - the FSA defines any food as "high sugar" if it contains more than 15gm of Sugar per 100gm in weight. Ofcom use this to ban the advertising of so-called "junk foods" on children's TV (not that there is much of that, partly because there's not much left to advertise). The FSA use these percentage figures for various evil ingredients (in their view) without any consideration to the actual amount eaten. So Marmite is really bad for the salt contents - but then who eats 100gm at a go. For that matter who eats 100gm of dry Bran Flakes? According to Kellogs, a portion of Branflakes is 30gm (which would be about 7gm of sugar - even if the average portion is a bit bigger, then actual amount isn't that high). Of course the percentage of sugar is even lower when the milk is taken into account (albeit he total amount is a bit higher).
Now compare this with orange juice. That passed the "high sugar" tests as it is only about 12% sugars. However, if we take an average (not very large) portion of orange juice as 200gm then that's about 24gm of sugar from that source, or over three times that from a portion of bran flakes.
The FSA has been promoting it's ridiculously simplistic "traffic light" labeling system on the basis that it is "clear". However, it is technically vastly inferior to the GDA system - the latter actually takes into account portion sizes, it allows you to plan a diet (there are no bad foods - just bad diets) and allows you to take into account the various ingredients that go to make up a meal (your bran-flakes and orange juice breakfast is high in sugar; but primarily due to the "green light" orange juice). But no, we have to go along with this infantilised FSA traffic light scheme that is fundamentally based on the idea that people are children.
Of course, the real thing the health food lobby don't want people to realise is just what huge levels of uncertainty there are in things like "safe drinking limits" - essentially much of the science is contradictory and changing. Take the fiasco of eggs being blamed for high cholesterol. None of this stops politicians and pressure groups acting as if it is certain.
Incidentally, for those (including the BBC) that think that "natural" sugar in foods) including honey) is fine and added sugar is "bad" then think again. The body doesn't much care - essentially all carbohydrates get broken down into sugars before they are absorbed. It's just that dissolved sugar is more immediately available, and the actual differences between glucose, sucrose, fructose, lactose and so on as far as the effect on the body are concerned are not that important (produce a fruit smoothy or orange juice and you've already made the sugar more readily available by breaking up the plant cellular structure). Also, contrary to much of what is said, the "evidence" that sugar gives you type II diabetes is minimal (being fat, not taking exercise does - and sugar will help rot the teeth). So keep the weight down, and make sure you eat all the nutrients, but don't think there is some magic level of sugars that will keep you healthy.
Nb. I emailed Ben Goldacre about the inadvisability of just quoting pre-digested (pun unintended) stories like the one he picked up vilifying Chris Hoy, but he too has a habit of ignoring things which don't suit his thinking (which also has blind spots). He recently posted another one about the PRS spat with YouTube/Google where he characterised it as "good news for independent musicians" as the commercial music industry was committing suicide (equating the PRS with record companies - far, far from the case). One of his blind spots is dislike for big companies (especially pharmaceutical ones).
