Oil price makes biodiesel competitive

Leichhardt Council in Sydney is taking the opportunity of high fuel prices to respond meaningfully to the threat of global warming by fully converting its fleet of 59 street-cleaning and council vehicles to use biodiesel. :::[Video].

Nick Dyer, the mayor for Leichhardt described the biodiesel as a carbon neutral fuel, "What is grown this year is used as fuel the next."

Other councils in Sydney have plans to go green, and Sydney Ferries is also said to have a biodiesel trial project underway. Because spilt biodiesel decomposes rapidly it is ideal for water transport.

You can fight cancer with exercise

Dr Andrew M M Haydon and colleagues at Monash Medical School in Melbourne have looked at baseline body mass index and levels of physical activity for subjects in the Melbourne Collaborative Cohort Study, a prospective study of 41,528 adults recruited between 1990 and 1994, and compared baseline levels of IGF-1or IGFBP-3 with those measurements. Insulin-like binding protein-3 (IGFBP-3) is a protein that inhibits another protein called insulin-like growth factor-1 (IGF-1) and in this way blocks IGF-1's proliferative effect on cell growth. Cancer is uncontrolled cell growth.

The researchers have identified new cases of colorectal cancer in this way as they analysed 443 colon cancer patients followed over more than five years: :::[SMH]

Among subjects who were physically active, an increase in
IGFBP-3 was associated with a 48 per cent reduction in colon
cancer-specific deaths. No association was apparent for IGF-1.

For the physically inactive, there was no association between
IGF-1 or IGFBP-3 and colon cancer survival.

Haydon said that "physical activity can increase IGFBP-3 levels,
which, in turn, reduces the amount of free IGF-1". IGF-1 has been
shown to stimulate cell growth, inhibit cell death, and promote
angiogenesis - the formation of new blood vessels, which tumours
need to grow.

This is not the first time a link between reduced cancer risk and exercise has been found:

"Other studies that have looked at this have shown a
dose-effect, meaning the more exercise the lower the risk, however
our study did not try to address this issue. We were examining the
effect of physical activity on one's prognosis following a
diagnosis of bowel cancer and the possible mechanisms behind this
effect."

Poor diet as bad as smoking.

A Dutch public health agency (RIVM) has concluded that eating too little fish, fruit and vegetables is as bad for human health as smoking in a new report by the Dutch public health agency that will be used in an upcoming European Food Safety Authority analysis of food and diet risks. :::[SMH]

Each year in the Netherlands, poor diet causes about 13,000 deaths due to diabetes, cardiovascular disease and cancer, while obesity claims 7,000 lives by causing heart disease and cancer, it said.

The Dutch researchers also say that about 25 per cent of deaths and serious illness caused by overweight and obesity would be avoided if all adults shed 3 kg.

"In particular, attempts at reducing saturated and trans fatty acid uptake and increasing fish, fruit and vegetables consumption could save many lives," the report said.

Hip to Tony Abbott's sleight of waist.

How is this guy, Tony Abbott, he who should never walk into a wind tunnel?

The story so far is that Tony Abbott wants to avoid regulating the food industry advertising their goodies to children and has come up with a proposal to supposedly address the grotesque childhood obesity figures Australia sees in the national mirror. He is happy for them to keep advertising to kids but wants to 'force' advertisers to prominently display percentage of the recommended daily intake of their product on their packaging.

Good job Tony. You are the Australian federal Health Minister; in today's upside down world your new job is not to protect the health of Australians from predatory food practices like pushing carbohydrate tolerance by calorie cramming or Little MacAthletics sponsorship programmes. Your job is to protect fast food, advertising and media companies and their constituent shareholders from skinny returns.

And like a mad monk of mammon you seem to have perfected the bald-faced lie to protect these profits:

The minister, who has refused to ban the advertising of food during children's television viewing hours, said that Sweden and Quebec had had bans for more than a decade "with no discernible impact on childhood obesity".

It does not take much research to check that Quebec has the lowest childhood obesity rates in Canada; a recent study by the Canadian Institute for Health Information (CIHI) has determined an unholy correlation between hip and knee replacements and obesity: Source: :::[CNW Group]

The provincial rates for obesity are generally in alignment with varying rates for joint replacement surgery. The provinces that reported the highest rates for hip replacements (Saskatchewan and Alberta) and for knee replacements (Manitoba and Nova Scotia) also have reported obesity rates that are higher than the national average of 23%. Mirroring the same relationship between BMI and joint replacement surgery, British Columbia and Quebec consistently had among the lowest rates for both surgeries and similarly have reported obesity rates that are lower than the national average.

That's because the kneebone is connected to the hip bone and the hip bone is connected to the tummy bone. A July, 2005 study confirms that childhood obesity in Quebec is well below national levels: Source: :::[Statistique Canada]

In 2004, the combined overweight/obesity rate of young people aged 2 to 17 was significantly above the national level in Newfoundland and Labrador, New Brunswick, Nova Scotia and Manitoba. The combined rate was significantly below the national level in Quebec and Alberta

Tony never had a childhood and doesn't have children. It's the only explanation for his seemingly blatant lie about his purported children's television food advertising restriction not working in Sweden: Source: :::[Swedish National Institute of Public Health]

11.2% of the girls and 14.5% of the boys were found to be overweight, and 3.3% of girls and 3.7% of boys were obese.

In Australia the proportion of overweight and obese children is 21% for boys and 23% for girls. With those jumbo ears Tony Abbott has, he needs a growing nose as much as our children need growing waists. Ok, I needn't be so harsh, I have checked my facts and he indeed does have children, but at least I do minimal fact checking; it seems Tony doesn't, or he does and is a liar. As it is rumoured he once wanted to be pope I am giving him the benefit of the doubt.

Not that I am against his basic concept for food packaging RDI labeling. Who could be? But it is no substitute to not creating the demand for excessive calories in the first place. Children get their calorie requirement messages from their bodies and it's worked fine for us throughout evolution. They don't need these naturally regulated messages overridden by increasingly sophisticated television advertising. Three other things strike me about the clear RDI labeling proposal if you are targeting children in the hope that they can control their calorie intake:

• once the Mars Bar is in the kid's hand it seems a measure too late to put a warming on the package - wouldn't banning Mars from advertising to children in the first place be smarter?
• you are going to need a RDI for each age-group, from tots to tweens to teens and twenty-somethings. Is this a plot to upsize products to accommodate a table on the label?
• you hope the kid can read at minimum, then understand the concepts of recommended daily intake, body mass index, so have basic biological and nutritional knowledge as well as the ability to calculate the accumulated daily intake adjusted to the child's age group.

How many of us adults can do that? It's much easier to teach your children that if the food that has no packaging it is far more likely to be healthier for them. And their children when they have them, because the carbon footprint of unprocessed and unpackaged foodstuffs is minimised.
