Would you have thought a can of Coke and a "97% fat-free" yoghurt had the same amount of sugar in them? If you didn't, well that's OK - you're not alone. This article looks at how "healthy" diets and "healthy" foods can be doing us more harm than good!

"Michael Pollan is desperate to end our addiction to processed food. Jon Henley hears why

Michael Pollan, tall, fit, not quite skinny but very definitely lean, is holding a fruit yoghurt in one hand and a Coca-Cola in the other.

"So," he says, "which do you think, per 100 grams, contains more sugar?"

The Coke, I reply. Duh.

"Wrong," he says. "The yoghurt. And look, it's low-fat. Isn't that great? We're getting fat on low-fat food."

It's a nice illustration of Rule Nine in Pollan's magnificently sensible new book, Food Rules.

Along with such gems as "Don't eat anything your great-grandmother wouldn't recognise as food" and "Don't get your fuel from the same place your car does", Pollan recommends that you "Avoid food products with 'lite' or 'low-fat' or 'non-fat' in their names."

His reasoning: if you remove the fat from a foodstuff, it doesn't necessarily make it non-fattening.

Certainly not if the producer ratchets up the sugar content to compensate.

In fact, Pollan notes, since Americans began producing low-fat food products, they have been consuming up to 500 extra calories a day. Brilliant.

Pollan, an award-winning author, journalist and campaigner, is on a mission.

Food Rules is, in effect, a condensation of his previous work: much of the science behind these 64 deliberately catchy injunctions towards a healthier diet ("The whiter the bread, the sooner you're dead") has already been expertly dissected in his earlier books The Omnivore's Dilemma and the US bestseller In Defence of Food.

The rules spring from two facts.

The first is that people who eat what Pollan defines as a western diet ("lots of everything except vegetables, fruits and whole grains") tend to suffer from western ailments: obesity, type 2 diabetes, cardiovascular disease and cancer.

The second is that people who eat more traditional diets - including those of certain indigenous peoples - that, by the lights of western food science, might be considered way too high-fat, high-carb or high-protein, do not tend to suffer from these diseases.

In other words, people can thrive on a wide variety of foods and diets, with one major exception: the diet most of us in the west are now eating.

So why are we eating our way to death?

Because for big food manufacturers, the western diet is payday, every day.

"The more a food is processed, the more profitable it gets," says Pollan, who refers to these products as "edible food-like substances".

And that status quo is not challenged by modern food science, which is all about identifying the "good" and "bad" nutrients in processed foods and tinkering with them - by lowering the fat, for example, or fortifying the vitamins - rather than questioning the value of processed food products in the first place.

"We don't talk about food any more," says Pollan.

"We talk about nutrients, omega-3, antioxidants, saturated fats, polyphenols. And so we play into the hands of the food marketers."

This all has the crushing logic of truth.

But can we do anything about it?

Pollan has little faith that Big Food will change voluntarily: legislation will be needed, he fears, although he takes heart from the Obama administration's victory on healthcare reform in the US.

"Pretty soon," he explains, "the insurance industry is going to realise that we have to tackle obesity and type 2 diabetes.

"They might even come out in favour of taxes on soft drinks. And once we see one powerful industry pitted against another, then we might see progress."

The complication of food has been under way for a long time now.

After agriculture became more productive following the second world war, "corn and soy and wheat and rice got cheaper - and the only way to make money out of them was to process them.

"A sort of arms race started to make food more complicated: don't buy flour, buy cake-mix; don't buy cake-mix, buy cakes.

"Don't buy oats, buy Cheerios; not Cheerios, cereal bars."

Is that process reversible?

It may have to be, Pollan argues, as we start running out of fossil fuels.

Big Food as it exists today is, patently, not sustainable.

Pollan is sure we can produce enough real food, but fossil fuels will have to be replaced by manpower.

"Organic farms are wildly productive," he says, "but a lot more labour-intensive.

So convincing is Pollan's logic that you wonder where it all came from.

He started out, he says, as more of a naturalist than a foodie, but was gradually won over by the notion that "what happens on our plate represents our most powerful engagement with the natural world".

He no longer eats junk food (though his teenage son does).

He acknowledges, though, that many of the exchanges he has about this issue "are with skinny people".

An interest in good food is, still, something of a middle-class preoccupation.

"But abolition, women's suffrage, those movements began as elitist too," Pollan says. "I won't be discouraged."

Will free Lap-band surgery fix the obesity or diabetes epidemic?

Will free Lap-band surgery fix the obesity or diabetes epidemic?

Posted by Christine Armarego AEP

Yesterday the media headlines were “Free Fat Surgery”! It related to a story about a government report which makes recommendations to the Australian Government on how to tackle the obesity crisis that costs $58 billion last year.  

One of the recommendations is for gym memberships to be subsidized.  Now this is certainly a step in the right direction especially with the GFC forcing people to make decisions based on money in the short term rather than the cost to their health in the long term.  However for many of the clients we see in “The Glucose Club” they get greater benefit from more individualized sessions rather than simply purchasing a gym membership, as this doesn’t guarantee attendance or weight loss.  Having caring, supportive and educated Allied Health professionals available who understand behavior change and are experienced in designing individualized programs, specifically if the person has injuries or a chronic health condition will make weight loss more likely.  Also not every one is interested in going to a gym – what about out-door training or a pool membership?  The government could also consider increasing the number of Enhanced Primary Care plan sessions available from 5 to 10 per year, allowing for more personalized care of those at greatest risk of developing morbid obesity.

They also recommend that Bariatric or Lap-banding surgery be subsidized by the government.  While this type of surgery is beneficial to those who are morbidly obese and who cannot exercise, there still needs to be education on nutrition and exercise and assistance in how to change these lifestyle habits to prevent the person falling into old habits. Surgery is only half the battle and it’s surgery plus support through lifestyle changes that is successful.  And bear in mind surgery has it’s own risks, including unsuccessful or procedures that need to be repeated.

I think the main problem is that the report is looking at ways to reduce weight – but have forgotten that the science shows that being fit is more important than being thin – and that is where their focus should be!  Being fit improves your glucose and insulin interaction and prevents metabolic health problems such as diabetes.

Fructose-sweetened Drinks Increase Nonfasting Triglycerides In Obese Adults

Fructose-sweetened Drinks Increase Nonfasting Triglycerides In Obese Adults


ScienceDaily (Feb. 12, 2009) — Obese people who drink fructose-sweetened beverages with their meals have an increased rise of triglycerides following the meal, according to new research from the Monell Center.
"Increased triglycerides after a meal are known predictors of cardiovascular disease," says Monell Member and study lead author Karen L. Teff, PhD, a metabolic physiologist. "Our findings show that fructose-sweetened beverages raise triglyceride levels in obese people, who already are at risk for metabolic disorders such as cardiovascular disease and diabetes."

Triglycerides are manufactured by the body from dietary fat and are the most common form of fat transported in blood. Although normal levels of triglycerides are essential for good health, high levels are associated with increased risk for atherosclerosis and other predictors of cardiovascular disease.

In the study, published online by the Journal of Clinical Endocrinology and Metabolism, Teff and her collaborators studied 17 obese men and women. Each was admitted two times to the Clinical and Translational Research Center at the University of Pennsylvania. On each admission, the subjects were given identical meals and blood was collected from an intravenous catheter over a 24-hour period. The only difference was the sweetener used in the beverages that accompanied the meals; beverages were sweetened with glucose during one admission and with fructose during the other.

Blood triglyceride levels were higher when subjects drank fructose-sweetened beverages with their meals compared to when they drank glucose-sweetened beverages. The total amount of triglycerides over a 24-hour period was almost 200 percent higher when the subjects drank fructose-sweetened beverages.

Although fructose increased triglyceride levels in all of the subjects, this effect was especially pronounced in insulin-resistant subjects, who already had increased triglyceride levels. Insulin resistance is a pre-diabetic condition often associated with obesity.

"Fructose can cause even greater elevations of triglyceride levels in obese insulin-resistant individuals, worsening their metabolic profiles and further increasing their risk for diabetes and heart disease," said Teff.

Fructose and glucose are forms of sugar found in both table sugar (sucrose) and high fructose corn syrup. Both fructose and glucose are present in lower concentrations in many fruits and vegetables. Although fructose tastes much sweeter than either glucose or sucrose, it typically is not used alone as a sweetener.

Future work will seek to determine how much fructose is needed to cause an increase of triglyceride levels when it is combined with glucose in beverages. Additional studies will explore the metabolic and health effects of long-term fructose intake.

In addition to her appointment at Monell, Teff serves as Associate Director for Translational Research at the Institute for Diabetes, Obesity & Metabolism, University of Pennsylvania School of Medicine.

Also contributing to the study were Peter Havel from the University of California, Davis and his colleagues Kimber Stanhope, Nancy Keim, and Bethany Cummings; Sean Adams, Ryan Grant, and Tamara Dunn from the USDA Western Human Nutrition Center; Joanne Grudziak from Monell; and Raymond R. Townsend from the University of Pennsylvania.
