Academic science: not fit for purpose

Richard Smith has another fascinating article about the way science has been practised in universities in recent decades, focusing particularly on The Big Fat Surprise, a book about the purported links between diet and health. It's full of quotable stuff; so much so that I barely know where to begin, but this, almost at random, gives a flavour of the thing.

[Ancel Benjamin Keys, a biologist at the University of Minnesota] studied few men and did not have a reliable way of measuring diets, and in the case of the Japanese and Italians he studied them soon after the second world war, when there were food shortages. Keys could have gathered data from many more countries and people (women as well as men) and used more careful methods, but, suggests Teicholz, he found what he wanted to find. A subsequent study by other researchers of 22 countries found little correlation between death rates from heart disease and fat consumption, and these authors suggested that there could be other causes, including tobacco and sugar consumption

Great stuff. The wider point though is how this mirrors stories familiar to BH readers: how challenges to the dodgy science were dealt with

Keys dismissed [the counterhypothesis] as a “mountain of nonsense” and a “discredited tune.”

...how politicians took it in unquestioningly

One congressional staffer, Nick Mottern, wrote a report recommending that fat be reduced from 40% to 30% of energy intake, saturated fat capped at 10%, and carbohydrate increased to 55-60%.

...how corporate interests took advantage:

It might be expected that the powerful US meat and dairy lobbies would oppose these guidelines, and they did, but they couldn’t counter the big food manufacturers such as General Foods, Quaker Oats, Heinz, the National Biscuit Company, and the Corn Products Refining Corporation, which were both more powerful and more subtle.

and how the consequences were less than benign:

The successful attempt to reduce fat in the diet of Americans and others around the world has been a global, uncontrolled experiment, which like all experiments may well have led to bad outcomes. What’s more, it has initiated a further set of uncontrolled global experiments that are continuing.

This all sounds very familiar. What you can see here is yet another example of academic science proving inadequate for informing public policy, serving up results that are half-baked, half-tested, and often already half refuted. When will politicians learn?

vegetables and fruits are really DANGEROUS when not processed

all the output of a chemical industry plus asbestos and radiation it is in it

we need to make soups not eat salds
eat very conformists fruit properly cultivated for centuries to which we have grown accustomed not any mango thrown at us from the turd world. apples pears and berries, preferably in compotes and stews.

the only safe food which can be eaten raw is meat actually: just 2 proteins stacked trillion times over

The cholesterol-sceptic community can be found here: http://www.thincs.org

The whole cholesterol heart-diet scam has been second only to the AGW debacle. Dodgy data, fiddled graphics, career scientists, government policies and advice, a falsely demonised product, cholesterol, (CO2). The whole thing is starting to fall apart, as with AGW, but it takes years and so much damage is done in the meantime.

There is a difference though. In the case of the man-made global warming fraud it seems to me that the politicians are the main driving force and all the hangers-on, scientists and the rest simply enthusiastically follow the money. When that money, extracted by force from taxpayers amounted originally to perhaps a hundred billion, their dedication to the cause is hardly surprising. Those billions then acted as seed corn resulting in something between one and two trillion more to be thrown away on this sad and corrupt fiasco. There is still no sign at the moment it's going to get better with the main culprits hell bent on bullying the laggards into submission if they show signs of revolt as Tony Abbott did.

In the early 1990s, the FDA came up with the concept of the food pyramids that was based on a high grain diet. Within a couple of years, low fat versions of just about every packaged and processed food product was on store shelves. To improve flavor, sugar, salt and other additives soared. The result was a doubling of type II diabetes in about a decade's time.

Weight loss is all about the magic number 3500. For any combination totaling 3500 from calorie reduction or increase of exercise and you'll lose one pound. For one pound week, that's 500 calories per day. Run, walk, lift weights, do the Ironman, toss the bun off the burger, eat lettuce all day -- just so the combination is 500 calories per day. Can't do 500? Then 250 calories will yield 1 pound per fortnight; 125 will mean 1 pound a month. It all depends what effort you're willing to make.

The problem with diet/economics/climate is that all the variables are interdependent which makes imputing causality of a single variable ie fat/oil price/CO2 pretty well impossible. That is not to say the variables are unimportant just that the outcome of their interplay is essentially difficult to model.

My story began about 2 years ago, arising from my research interests and becoming conscious of weight gain. My experiences parallel Maurizio's. If anything he's only slightly older than me. It took about 4-6 months to throw the metabolic switch, so to speak - you avoid bread and carbohydrates - fully. Obviously this is not a practical or easy option, which is probably why it takes so long. But I did lose weight. Absolutely no exercise whatsoever. I fit into my old clothes - suits and pants - a major plus point and motivation. Eat all the meat, egg, fat and butter you want - you will be fine. Buy the burger, throw away the bread, eat the veggies and the meat.

You'll also realize how hard it is to find the food required to satisfy such a diet. Junk food and carbs are everywhere, protein is hard to find.

I have read Teicholz's book and Gary Taubes. I would encourage anyone interested in good science and good food to read Taubes and follow his work.

Im like Omnologos, I removed starch (bread, potatoes, flour), processed foods, sugars from my diet while slowly increasing exercise and over the course of the last 12 months have lost 31kg.

Im now regularly running 10k in the same amount of time as it used to take me to run 5k when I first started running and am absolutely loving being fit and active (whereas before I was also active BUT just wasn't all that fit!).

What I haven't done is cut my fat intake. I absolutely CANNOT stand green top milk simply because its tastes like nothing more than diluted water and utterly love meat with fat and dont even get me started on the benefits of butter over processed margarines! Rather counter intuitively fat acts as a natural appetite suppressant and well tastes just so god damn good! :)

Pretty much the ONLY non-fat product I touch is Weight Watchers fruit yoghurt simply because of all the yoghurt out there it has the lowest sugars and rather bizarrely very little in the way of additives (ie. there is nothing being added to increase taste because the fat has been removed). Otherwise I avoid low fat food like a fat chick avoids exercise that doesn't involve being on her back with her legs up in the air.

I feel vindicated, Entropic man said this You've even got SandyS talking conspiracy, someone I had thought more sensible. (not that anything EM says should bother anyone), when I suggested Ancel Keys and his followers were no better than CliScientists except he got away with it. Original discussion.


I don't want to divert this into a discussion on diet, as I think there are problems with what we eat in the Industrialised nations, however life expectancy in the UK is still increasing.

I've been aware of Ancel Keys for a long time, I suggest you do a bit of research and then think about plans to put the entire nation on to statins. Pharmacy, low fat yogurt and butter replacement companies just love the fear of cholesterol. It's quite possible that it wasn't him who exploited his research for financial gain but fortunes have been made on the back of it and a lot of bad advice has been handed out. It will take another generation before the truth comes out on dietary fats.

Funnily enough it was through an item on the old BBC that made me aware of Keys' cherry picking.

There was a thread on this topic at Jo Nova's site a while back. The parallels between CAGW and anti-fat are startling. Substitute cholesterol for CO2, saturated fat for fossil fuel, George McGovern for Al Gore, fishermen in Norway(sic) for that tree in Yamal, ignoring anecdotal evidence (e.g. pre-refrigeration diets), discarding inconvenient facts (e.g. the Inuit), the failure of models to predict,etc. When I read this book all I could think was " climate change scam". Somebody could write an interesting paper comparing the two.

What is scary: Keys started this in the 50's and it is still going strong. You have 3rd generation "scientists" who don't question this.

What is scary #2: the low-fat "science" was largely based on middle-aged men without concern for the impact on women and children. The latter are being denied the foods that help their development. I particularly worry about low-income children who rely on the school lunches for quality food and they are getting politically correct tasteless food instead. I don't have the data to back this up but it would be really interesting to plot IQ scores against percentage dietary fat.

Well worth reading if you have an interest in the subject.

Keys once said :

"The evidence—both from experiments and from field surveys—indicates that the cholesterol content, per se, of all natural diets has no significant effect on either the serum cholesterol level or the development of atherosclerosis in man."

So like I said, it is a complex story.

The reality about dieting and weight loss that has been proved in numerous trials from the 1950s on is that it is caloric intake that counts not the source of the calories such that allowing for changes in water balance the results are similar for either high fat or high carbohydrate diets. The important factor is how readily the needed restricted intake is achieved and can it be done without lowering metabolic rate. This involves appetite control and it has been shown that both high fat diets and carbohydrate diets high in fibre will achieve similar results, as will diets with a low glycemic value that restricts the rate of uptake of glucose; if the rate of uptake is too fast the brain does not have time to react and limit intake through satiety but high fibre diets fill the stomach and restrict intake and high fat diets give a more rapid hormonal feedback that achieves similar ends. What is more important is the effects of these diets on health and there is good evidence that a high carbohydrate diet supplying around 35 - 50 grams of fibre per day is most effective in limiting the potential for the onset of the metabolic syndrome that is associated with obesity, diabetes, heart disease and cancer. As in all things a little knowledge is a dangerous thing and claiming large benefits for weight loss from high fat and protein diets in the short term can lead to more serious health problems in the longer term. Ideally one needs a diet that matches daily needs for energy, fibre, amino acids and fatty acids, as well as minerals and vitamins. In addition a certain level of activity is needed to maintain metabolic rate and especially muscle mass and activity. I have consumed a 65% high fibre carbohydrate diet for over 50 years and am the same weight as I was at age 20 with an 'ideal' BMI of 22, but then as a nutritionist I practice what I preach.

Sean,

"The result was a doubling of type II diabetes in about a decade's time."

Actually, the doubling of Type II diabetes was the result of re-defining what normal blood glucose levels should be. This happened at the same time as the re-classification of BMI classes, hypertension (blood pressure) levels and cholesterol levels in the late 1990's.

These re-definitions have resulted in about 50% of adults in the US being diagnosed with a 'disease' which previously did not even exist. This was predicted in a paper in 1999 (Schwartz LM, Woloshin S. Changing disease definitions: implications for disease prevalence: analysis of the Third National Health and Nutrition Examination Survey, 1988-1994. Eff Clin Pract. 1999; 2(2):76-85) and has since been noted in a number of Cochrane reviews of the separate 'diseases'.

Our diets have changed a great deal in the past 50 years, but the in the last 15-20 years the cause of (supposed) ill-health has been the health industry not our behaviour.

The knock-on effect comes with getting insurance. One company asked me if I suffered with high BP; I said, no. They countered by asking if I took BP pills. 'Yes', I said, 'and I don't suffer high BP as a result'. But they wouldn't accept that. It's like saying a broken leg that has been healed by treatment is still broken.

Further to my post @ 4:04... I had a big argument with my Doctor about my diet. "You must take more carbs...etc. I quietly told him that my qualification were higher than his and my whole life had been spent in research and development, then surely my several months of reading scientific papers enabled me to judge what science was correct.

Great to meet fellow dieters and some with my experience. I believe some of us are genetically very good at converting excess carbs into fat. That's why Fatso is our natural condition.

There are also different ways to lose weight at different ages . When 30 caloric control is enough. Not at 47 when it's a metabolic war.

of course carbs will come back in my diet as soon as I reach my target. Maybe they'll be high carbs and low carbs days, alternatively. Haven't discovered the magic mix and will try Peter's suggestion.

My previous GP had some very sage advice about diagnosing hypertension "never believe a blood pressure reading unless your patient has been seated and relaxed for at least 30 minutes before taking it". Try it yourself if you've got a home BP monitor, do before and after relaxing readings.

There's definitely a link between processed food and diabetes, some cardiovascular diseases and cancers, but I believe it's got more to do with the crap that's added to them as 'healthy' alternatives to natural fats and sugars. As for the current rises in food intolerances and allergies, I think a lot of these are either self-diagnosed or diagnosed by unqualified 'dietary consultants'.

The dieting and dietary supplement industries are still very poorly regulated compared to the pharmaceutical industry, or even the main food industry - and there's a lot of gold in them thar diets and imagined ailments.

Having hit the giddy heights of 18 stone following years of on/off low-fat hi-carb diets I thought I'd give it a go. After a year I am down to 13 stone, I no longer need hypertension medication, my blood chemistry is excellent... but best of all I never had hunger pangs once, and I enjoyed the food.

Unfortunately, if the green blob and the renewables parasites get their way they will have a significant effect on all our diets. My recollection from my working days was the 75% of the UK landmass is agricultural. Of this; about 26% is permanent downland pasture (dairy, beef finishers, sheep, outdoor pigs and poultry), 37% is arable and 37% upland grazing (sheep and beef starters).

Up to 5% of UK agricultural land (mostly downland/arable) is now being used, or intended to be used for biomass/solar, so with a growing population we're either going have import more food, or going back to foraging to make up the deficit (hardly a realistic option).

I was always fit and active until six years ago when I developed a chronic cough sometimes so bad that I would be coughing literally a thousand times/day..many many tests including scoping, biopsy, stress tests, allergy, cat scans on heart throat sinuses and four specialists proved little except that I didn't have cancer or a bad heart or a lung disease. So they said I was asthmatic and puffers of all kinds were prescribed most of which did little good..occasionally antibiotics helped for a span of weeks to as long as six months. I also got fat adding 35lbs to the 215 I already had.
After reading about the benefits of fasting for as little as three days in helping "reorganize" my immune system I tried it a few times in conjunction with the LCHF diet. I was surprised how easy the weight came off and my breathing seemed better also. Now 35 lbs lighter in eight weeks and eating only once/day between 5-9pm I've gone from a donut lover (grew up in a bakeshop) to a satiated happy consumer of veggies, fat and protein. As an aside won $100 in my weeight loss bet!

So happy to read this! We've been conned for so long on dietary advice.

Like many here I'm on a high fat / no carb diet. Started 4 months ago and am now back to the 32" waist I had at 18 years old - I'm 45. Never had to feel hungry - the reverse.

Try the Bulletproof protocol. It works for me. Coffee with butter (I know sounds strange) in the morning, gives you energy the whole morning. Instead of the "brand name" bulletproof coffee, I do regular coffee with 1g activated charcoal to absorb mycotoxins.

For fat - think coal - long burning energy.

For carbs - think a handful of twigs - burns bright, but you have to reload every few minutes.

Such an important part of it is the gut bacteria. Some convert fats into energy, and some convert carbs. If one wants to promote the fat burning ones - just eat more fat...

The issues are undoubtedly complex. Unlike climate where you are told of a certain reality and no self-experience or experimentation is possible, the question is that of food and all of us have our own experiences to form opinions. Self-experimentation is possible with food. You may or may not believe in esoteric diets and fad diets, and I certainly don't, but look up Seth Roberts and his method of self-experimentation.

Teicholz and Taubes, as journalists, trace the history of the evolution of thinking about cholesterol, fat, and carbohydrate in the Western diet. The problem, at the least in the US, as Mike W and several others have pointed out, is while governmental dietary advice is likely only minimally related to individuals diet habits, it has an enormous indirect impact.

Dec 16, 2014 at 10:15 PM | Registered CommenterSalopian

Salopian, I don't know what you got from my advocacy of 'self-experimentation'. I was not clear enough. I say 'self-experimentation' in the most benign possible way. Roberts became known for experimenting with weird foods and strange practices. What I took away from what I learned about him was just the willingness to change dietary habits, stick to a plan long enough to see effects. My baseline habits were eat thrice a day, all carbohydrate rich, meat-lean food with junk food ad libitum. Whatever meat there was, was mainly chicken. There was not a package of snacks - be it chips, cookies or any crumbly stuff that I would not open and eat the whole of. If I tried curbing, I would tell myself how girly I was - being conscious of my diet. Even with all I did not become 'fat', but definitely overweight.

My 'self-experimentation' consisted of trying and avoiding different food options available to me, both at home and at work, until I found something that worked. This included such ignorant moves as trying pita bread and hummus on a regular basis (because I believed the caloric content label and the 'Healthy' tag) for a long time. This was considering I was attempting to start work in a related area of research! I learned of the Atkins diet only much later. A variant of Atkins - which is what a low-carb/high fat diet mentioned by many here is - is ultimately what is practicable and what works to lose weight. You get leaner, don't lose muscle mass and don't go hungry all the time. In any case total carbohydrate avoidance is near-impossible - possible only if your full-time job is to be messing with your diet and exercising as celebrities can.

So self-experimentation simply refers to tweaking your diet to achieve a certain goal. In my view, that eating and eating habits should be natural is a given. The question therefore becomes - 'what can be done, within these limits, to avoid the slow onset of weight gain and other manifestations of the metabolic syndrome?' I am still amazed by the fact that it is possible and I figured out the answer by myself.

My experience re weight loss by cutting carbohydrates, mostly bread in my case, is parallel to those of the other posters above with a slow sustained loss of around 20 kgs of weight over a couple of years.
One slice of bread particularly after about midday seems to be worth about a half kilogram increase in weight at the following morning's weighing session.

One very interesting personal experience was the recent purchasing of small deep fryer which led to the consumption of quite a lot of rather tasty deep fried tucker which I had never really ever had a great deal of previously being a rural person far from town and only an irregular patron of the fast food establishments.

A few months later I received a very hard rap over the knuckles from my Doc on my rapidly rising blood sugar levels which had reached the diabetes thresh hold point.
At 76 years of age until that point, my blood sugar levels had always been quite some distance below the diabetes thresh hold levels.
So some deep thinking about what had changed in my personal living and eating habits to account for that sudden increase in my blood sugar levels
And the answer appeared to be closely related in timing to the purchase of that deep fryer.
So out the deep fryer went for a few months, sadly never to return as that deep fried tucker tasted real good..

Within weeks down came my blood sugar levels to the previous long established personal level and all is again well with any fear of a diabetes onset dispensed with or at the very least delayed into the future or whats left of it for myself...

All of which raises in my mind the possibility that a high percentage of the current diabetes epidemic being primarily associated with excessive consumption of deep fried type processed fast foods, the rapid spread of which is only a fairly recent development.

On a related note and especially relevant given the season, bear in mind that the UK recommended units of alcohol consumption for males and females have long been acknowledged as having been plucked out of the sky with no scientific or medical evidence, but the meme sails on serenely with self-reinforcing constant and mostly unquestioning repetition.

Now for another of my "five a day"... vodka counts, right?

Cheers!

@ptw
"vegetables and fruits are really DANGEROUS when not processed
all the output of a chemical industry plus asbestos and radiation it is in it"
Sorry, but your advice is not even based on scientific evidence. Show me the clinical effects. Radiation: ever heard of radon? Asbestos: how would that get into vegetables?

Here we talk shoddy science and even comments are full of it!
Radioactivity is ubiquitous, water and soil emit radioactivity. Bananas are naturally radioactive, they contain potassium, but you couldn't eat enough bananas in 100 years to produce a clinically notable effect.

/sarc By the way, apes mutated to humans because of the radiation from bananas /sarc
