Junk food addiction

Posted by Colin Rose on October 28, 2009

The type of reactions Kessler describes when some people are presented with junk food is classical addictive behaviour. Why doesn’t Kessler like to call junk food obsession an addiction? My guess is that as a former FDA Commissioner he would like to think that the problem can be solved just by banning junk food. If he admits the existence of  junk food addiction he has to face the reality that all attempts to ban addictive substances of any sort have been disastrous; people will satisfy their addictions at any cost to themselves and their society. Whether we like it or not, we are all affected by the consequences of addiction; if you have any kind of disease insurance, public or private, you are paying much more than you would if there were no alcohol, tobacco or junk food addictions, all legal. Illegal cocaine and heroin addictions only increase your share of police and military costs. So, collectively, we have to put a  major effort into preventing and treating addiction, a medical problem so intractable that we pay police rather than doctors to deal with it.

You can say no

Posted by Colin Rose on October 27, 2009

A great book, but Kessler calls everything that can be digested “food”. Artificial concoctions formulated to appeal to addictions to sugar, fat and salt are junk food and have no more reason for existence than cocaine or tobacco. It is impossible to eat too much of unrefined cereals, vegetables, fruit, legumes, low-fat dairy products or lean meat with no added butter, margarine or oil.

To understand how eating promotes more eating, we must first understand the concept of “palatability” as the term is used scientifically. In everyday language, we call food palatable if it has an agreeable taste. But when scientists say a food is…read more…

Weight gain destroys body and mind

Posted by Colin Rose on September 30, 2009

Being obese in middle age lowers a woman’s chance of being alive and free of chronic diseases after age 70 by nearly 80 per cent, according to new data from the landmark U.S. Nurses’ Health Study. The findings suggest every bit of weight gain between ages 18 and 50 lowers a woman’s odds of being a “healthy survivor” – living to age 70 or older, free from 11 major chronic diseases as well as physical, cognitive and mental impairment. For every one kilogram of weight gain since age 18, the odds of healthy survival decreased by five per cent, the study found. The worst odds for a long and healthy life were among women who were overweight at 18 – with a body mass index greater than 25 – and who gained 10 kilograms or more by mid-life. But even a higher BMI at 18 alone was associated with “moderately, albeit significantly” reduced odds of healthy survival at much older ages.

“When diet doesn’t work”

Posted by Colin Rose on September 21, 2009

Here is a graphic illustration of the concept of moral hazard as applied to the drug treatment of lifestyle diseases.

—————————————————————-

Reprinted from AdWatch

LescolItaly2008-04

Many studies confirm that doctors’ behaviour can be influenced by drug advertising, but many of them are unaware of this.
Not only the advertising text, but also the images play an important part.
See below, for instance, the image in the Lescol advertisement published in the April 2008 issue of Rivista SIMG (Journal of the Italian Society of General Practitioners).

Lescol (fluvastatin sodium) is one of the statin class of drugs used to treat of high cholesterol when diet and other lifestyle changes don’t work.
The Summary of Product Characteristics states “for best results in lowering cholesterol, it is important that you closely follow the diet suggested by your doctor”.

What kind of advice could the doctor have given the two people on the beach?

They seem to be really happy and relaxed. The pastel colours, the calm sea and the blue sky in the background convey the impression that all is going well and no changes are needed.

The designer must have been influenced by the Colombian painter Fernando Botero, famous for his fat men and women, who generally emanate a sense of calmness and satisfaction.

What I can understand, as a doctor, after looking at this image?
“It doesn’t matter what I advise my patients to eat; it isn’t worth them trying to change their lifestyle behaviours.
Only the pill can make the difference!”

Low fat diet trumps junk food gene

Posted by Colin Rose on September 19, 2009

ScienceDaily (Sep. 14, 2009) — The risk of becoming obese is 2.5 times higher for those who have double copies of the best known risk gene for overweight and obesity. However, this is only true if the fat consumption is high. A low fat diet neutralizes the harmful effects of the gene.

“This means that the critical factor is what you eat. At least in the case of the FTO gene, the most important obesity gene identified so far,” says Emily Sonestedt, member of Marju Orho-Melanders research group at Lund University Diabetes Centre.

She is the main author of a study that is currently being published in the American Journal of Clinical Nutrition. Several studies have found that exercise diminishes the effect of the risk gene but this is the first study where the effect of the gene has been studied in relation to food habits. The risk variant of the FTO gene (fat mass and obesity associated) is common in the general population. 17 percent have double copies, meaning they have inherited it from both parents. Another 40 percent have a single copy.

“It is difficult to calculate how much people eat with any certainty, which is one of the reasons why no one has done this before. But we have good data” says Emily Sonestedt.

The information comes from the large Malmö Diet and Cancer study where food habits were carefully documented using, among other things, an extensive questionnaire, a long interview and a food diaries kept by the participants themselves. When the eating habits of the carriers of the double risk variant for obesity was analyzed the pattern was clear. The risk of obesity was dramatically increased only in the case of high fat consumption.

“Yes, for those who had a diet where less than 41 percent of the energy consumed came from fat, obesity was not more common, in spite of the inherited risk” says Emily Sonestedt.

The FTO genes acts in the hypothalamus, the part of the brain that regulates appetite and satiety, and the risk variant has been connected to an increased energy intake, especially in the form of fat.

“It could be that the carriers of the risk gene don’t feel as full from eating fat and therefore consume more and gain weight” says Emily Sonestedt.

The finding that the harmful effects of the gene can be cancelled by changing eating habits could, combined with mapping of the effects of other obesity genes, lead to better and more individualized nutritional counseling for those that want to avoid gaining weight.

“This shows that we are not slaves to our genes. Even if we are born with an inherited predisposition to obesity, life style is important” says Emily Sonestedt.

WHAT YOU EAT MAKES YOU FAT

Posted by Colin Rose on September 13, 2009

Great article, Joe. We appreciate there are those that are confused. But there are also large numbers who know what is healthy to eat, but easily blind themselves to reality; they are junk food addicts. That “food” they are piling on their plates is specifically formulated to appeal to addictions to sugar, salt and the mouth feel of fat. Extensive advertising of these high calorie density, low nutrient density foods, “junk food,” reinforces this desire, and gives legitimacy to guiltlessly indulge the addiction. That “food”  that the cruise passengers are piling on their plates is specifically formulated to appeal to addictions to sugar, salt and the mouth feel of fat. Unfortunately, treating junk food addiction is just as hard as treating addictions to tobacco, cocaine or heroin. Doctors are not trained to and not paid to treat addictions. They are paid to “treat” the symptoms of junk food addiction, like hypertension, Type 2 diabetes and “cholesterol” and do futile gastric bypasses. “Treatment” of these symptoms deceives the addict into believing that s/he can avoid the consequences of the addiction and makes the addiction worse. Americans are inundated with direct-to-consumer (DTC) drug advertising, claimed to be a First Amendment right by corporations with $billion ad budgets, promoting this deception and doctors are paid to prescribe those drugs.  Canada is catching up fast. Obesity rates are rising and there is pressure from the media to allow DTC in Canada, presumably guaranteed by the Bill of Rights.

The solution? Each individual has to balance the transient pleasure of addiction against the long term disastrous consequences of the addiction. In our society this is the hardest thing most people have to do 24/7/52 for a lifetime and doctors must avoid aggravating addictive behaviour.

Advice from the Government of Canada – Put more pork on your fork

Posted by Colin Rose on July 18, 2009

Here is another great example of the Canadian Government’s concern about the health of the population and the environment. Industrial production of high-fat content, nutritionally unnecessary pork is one of the most environmentally destructive of agricultural activities. So when the pig feeders scream about H1N1, the high cost of corn and protectionism in the US does the government dare say that it takes about 6 pounds of corn to produce one pound of pork, so eat the corn instead, which is healthier too. That would be political suicide; hundred of porkers would block highways with their tractors. No Gerry Ritz, Minister of Agriculture says we should ruin our health and the environment by eating MORE pork. That keeps the porkers happy and keeps him in his job and encourages even more people, with limited entrepreneurial creativity, to take up pig feeding.

Of course, if all domestic swine were eliminated world-wide, there would be no more reservoir to generate nasty influenza viruses which have killed millions of people in the past and will probably do so in the near future. Billions of people with dietary rules forbidding pork manage to live quite normally without any pork. The rest of the world would be better off without any domestic swine, too.

Ottawa considers culling hogs

H1N1, feed prices add to industry’s decline

PATRICK WHITE

Globe and Mail

Saturday, July 18 2009

The federal government is poised to trim the fat out of Canada’s hog industry and is considering culling the entire sector by up to 20 per cent to do it.

The move would respond to pleas from a struggling pork industry that has found itself overextended in recent years as flagging demand and high feed prices have sheared profits down to nothing.

‘We can’t continue on like this,’ said Jurgen Preugschas, an Alberta hog farmer and president of the Canadian Pork Council. ‘I can’t pay my bills right now. That’s why we need the government to step in and assist producers so that the industry can stay in the game. Otherwise, a meltdown would jeopardize about 42,000 jobs.’

In past years, the council has urged the federal government to assist tapped-out hog producers with loans and advances that would keep their operations afloat until favourable markets returned.

But the lobby group now seems resigned to the prospect that the high times are gone for good.

In its recently released Strategic Transition Plan, the pork council calls on the federal government to buy out the worst-off producers at $500 per sow, plus the market value of the animal. By 2014, the plan foresees an 18-per-cent drop in Canadian pork production, from 31 million pigs in 2008, down to 25.5 million. That would follow on a 13-per-cent contraction over the past three years, according to Statistics Canada figures. ‘We are having day-to-day discussions with Canadian Pork Council,’ Agriculture Minister Gerry Ritz said yesterday, ‘reviewing their proposal, and working together to find a solution that will help hog producers in this difficult economic climate.’

The brunt of those difficulties comes from a dismal bit of math: producers need more than $150 per pig to break even, but they’re only getting around $120.

‘Usually the summer brings a rise to about $170,’ said Mr. Preugschas. ‘But we just haven’t seen the increase this year.’

A battery of events have contributed to the shortfall. The H1N1 outbreak, also called swine flu, closed off a number of international markets and weakened North American demand. The recession has also severely cut down protein consumption in all forms. And new Country of Origin Labelling requirements in the United States have severely interrupted cross-border shipments.

‘Before the COOL laws, the business model between Canada and the U.S. worked very well,’ said Mr. Preugschas. ‘The U.S. government wrecked a very good business model.’

But the biggest hit of all has come in the from of skyrocketing feed prices. Corn that once went for $2 a bushel now hovers around $3 – with no drop in sight.

‘I think that this shift in prices is set for the long term,’ said Derek Brewin, agricultural economics professor at the University of Manitoba. ‘The ethanol programs in the U.S. have pushed corn higher, and that will likely remain that way.’

The Department of Agriculture will be announcing some manner of assistance package in the coming weeks. So far, Mr. Ritz is only offering a verbal boost to the industry: ‘Canadians can help tremendously by putting more pork on their fork and their barbecues this summer.’

Obese dying awaiting operations

Posted by Colin Rose on June 3, 2009

Dr Nicholas Christou, a bariatric surgeon, claims that obese people are dying for lack of bariatric surgery. Do you ask a barber if you need a haircut? There is not a single randomized, sham-operated, controlled trial proving that gastric bypass or banding has saved even one life. Morbidly obese people are not dying from lack of bariatric surgery but from junk food addiction . Before the discovery of drugs for reducing stomach acid, many thousands of gastric bypasses were done to treat peptic ulcer disease but they were never associated with major weight loss. But now stomach surgery is touted to be the cure for obesity. If “diet and exercise” don’t work then why do patients after bariatric surgery still have to “stay on their diets”? Quite likely, bariatric surgery “works” only because patients are convinced that they must control their addiction or suffer abdominal pain. Eventually they discover they can eat as before and, if they haven’t mastered their addiction, regain the weight. Before we spend many billions of dollars on this unproven “treatment” a controlled trial is essential.
