Biting the bitter bullet

The other day we took a short trip around obesity (Obesity and Cancer) in the course of which we noted that the former is a bad thing. So, you might say, they make a good pair – indeed they quite often come hand-in-hand, as obesity significantly increases the risk of quite a lot of cancers as well as other unpleasant conditions. The nasty effects include heart diseases and diabetes, a collection of problems often referred to as metabolic syndrome.

Fed up?

Obesity is usually caused by eating too much of the wrong stuff whilst parked on your rear end. True enough, but folk sometimes get a bit cheesed off by repeatedly being told to do something about it. As it happens, turning to Cheddar, if you can face the stuff, may actually help weight loss as cheese is high in protein and fills you up. And you might just go for that escape route when you’ve been leaned on by a recent article that, in effect, calls for draconian measures to limit the amount of sugar we eat. To be slightly more precise, the target is the USA because, as is well known, Americans lead the world in pretty well everything, including bad eating habits. The scientific dynamite propelling the charge is that sugar consumption worldwide has gone up three-fold in the last 50 years. The average American now eats over 600 grams of the stuff every day, a feat that leaves the rest of the world scarcely within range of a podium spot. It may seem a bit odd to be left trailing at anything by the most obese nation in the world (let’s leave Nauru –pop. 9265 – and a few other South Sea islands out of it)  but the link here is, of course, that sugar is a great source of calories and that the more calories you shovel down – in whatever form – the bigger you tend to become. But don’t get too cheeky about Yankee obesity as us Brits aren’t in great shape either.

Condensed facts

Very roughly an ‘average’ person needs about 2,100 calories a day. 600 grams of sugar would give between one third and one quarter of that total requirement. For an historical perspective that’s about 14 times as much sugar as the denizens of Great Britain were allowed during the second world war under rationing – a period when our diet is generally considered to have made us healthier than we’ve ever been. So you could say an element of control has been lost.

Calorific confusion

The ‘2,100 calories’ above are ‘food calories’, the unit sometimes used in nutritional contexts. It’s 1000 times bigger than ‘scientific’ calories, or gram calories (cal). Scientifically therefore, we mean 2,100 kilocalories (kcal). Which is why your fruit juice carton may tell you one glass contains 50 kcal. And, just to stop you asking, 1 calorie is the heat (energy) you need to raise the temperature of 1 gram of water from 14.5oC to 15.5oC.

An all-round view of the problem

Sugar consumption has ski-rocketed, eating too much of it unbalances your diet and bad eating habits can cause obesity and metabolic syndrome. But these things aren’t black and white: 20% of obese people have normal metabolism and a normal lifespan whilst 40% of those of normal weight will get metabolic syndrome diseases. So, whilst obesity indicates metabolic abnormality, it is not per se the cause.

The underlying science remains a matter of debate – a story well summarized by Gary Taubes. What is not in question is that we eat more sugar than we need and the real crunch is that sugar is like tobacco and alcohol – no, it doesn’t make you smelly or do Sinatra impressions – but it is addictive. It actually manipulates your pathetic brain cells so you keep asking for more.

On your Marx

So we’re seduced into eating more and more of something that can help us get fat and ill. What’s to be done? Lenin, who was fond of asking this question, would have dealt with it in a trice by limiting sugar supplies to one tenth of the dietary minimum and seeing who survived. Ah! The good old days. But the authors of the recent article had to come up with a pc 21st century equivalent. Of course! Taxation. And they’ve a point – you can tell people that smoking will give them lung cancer til you’re blue in the face but the only thing that stops them committing suicide is jacking the price up. Don’t ask me. Something to do with human nature. So it sounds like a good idea – but to have an effect on sugar you’d need a huge increase across a vast range of foods – fruit juice, ‘sports’ drinks, chocolates, sweets, cakes – forget it.

Do I have a solution? Of course! Bring back rationing. For all foods. Set at the UK second world war levels. Now we’d think about what we eat – carbohydrate, protein and fat – reverse obesity trends, solve world food problem, slash health service costs, cut queues at supermarkets (so they’d be normarkets). And we’d be rid of most of those damned cheffy t.v. programmes. Vote for me!!
