the "soda rivers


NEW YORK: A New York judge blocked mayor Michael Bloomberg's planned ban on giant sodas, dealing a setback to his public health agenda just hours before curbs on selling such drinks were due to begin.

Judge Milton Tingling ruled that measures to restrict soda servings to a maximum of 16 ounces (470 millilitres) in restaurants and other venues, were "arbitrary and capricious," and he was barring the plan "permanently."

Bloomberg has made health issues a key plank of his administration, banning smoking in restaurants, bars and other public places. He quickly denounced the judge's decision on sodas as "clearly wrong," and said the city would appeal.

"I am trying to do what is right to save lives. Obesity kills," a visibly angry Bloomberg told reporters, noting that 5,000 New Yorkers and 70,000 US citizens would fall victim to the disease this year.

"Sugary drinks are a leading cause of obesity. We have a responsibility as human beings to do something, to save each other," he added.

But Bloomberg's super-sized soda ban, which would have been a first for a US city, sparked frenzied debate, with petitions and media campaigns from both sides.

Some supported Bloomberg's arguments, emphasizing that 30 years ago the average soda serving was just six ounces, but that these days, it's not rare to see young Americans with giant fizzy drinks of more than a liter (33 ounces).

Opinion polls over the summer indicated that a majority of New Yorkers opposed the limited ban, with some suggesting the mayor was impinging on civil liberties and others arguing the rules would not be effective.

Industry lobby groups led by the American Beverage Association (ABA) and the National Restaurant Association took the court action that led to Monday's judgment, and they praised the decision.

"The court ruling provides a sigh of relief to New Yorkers and thousands of small businesses in New York City that would have been harmed by this arbitrary and unpopular ban," the ABA said in a statement.

As well as the thousands who die each year from obesity-linked problems, one in eight adult New Yorkers has diabetes, which can be aggravated by sugar consumption, and studies have shown that sodas, which often cost less than bottled water, are a contributing factor.

"Remember, for many years, the standard soda size was six ounces -- not 16, it was six, then it was 12 ounces -- and people thought that was huge. Then it became 16, then 20 ounces," Bloomberg said.

"We believe it's reasonable to draw a line -- and it's responsible to draw a line right now," he added.

The New York Board of Health approved the measures last September and they were due to come into force on Tuesday in restaurants and places of public entertainment, such as stadiums.

In a boost for the soda limits, the newly-built basketball stadium for the Brooklyn Nets had said it would immediately adopt the rules.

But under the measures put forward by the city there was nothing to stop people from buying as much soda as they like by refilling smaller containers.

Also, the ban did not extend to drinks sold in supermarkets or any dairy or fruit drinks, many of which also contain huge quantities of sugar.

Diet and alcoholic drinks were also exempted under the city's plan.

"The exclusion of all alcoholic beverages from the ban is completely irrational. Beer and soda have nearly the same calories per ounce," the legal complaint said.

And "the application of the ban to some business establishments but not others is arbitrary and capricious," it argued.

Bloomberg previously acknowledged that the plan would fall short of ending over-consumption of sugary drinks, but he said the disappearance of mega-sized cups would at least make people more aware of what they were consuming. (AFP)

Less sleep leads to more eating, weight gain


WASHINGTON: Sleeping a mere five hours a night during a work week with unlimited access to snacks isn't good for your waistline.

A study, led by the University of Colorado at Boulder, found that participants gained nearly one kilogram when put in such a situation.

Previous studies have shown that a lack of shut-eye can lead to the packing on of kilos but the reasons for the extra weight were unclear, according to the authors of the latest research.

Published in the Proceedings of the National Academy of Sciences, the newest findings show that, while staying awake longer did indeed require more energy, the extra calories burned were more than offset by the amount of food the study participants consumed.

"Just getting less sleep, by itself, is not going to lead to weight gain," said Kenneth Wright, director of CU-Boulder's Sleep and Chronobiology Laboratory that lead the study. "But when people get insufficient sleep, it leads them to eat more than they actually need."

The researchers monitored 16 young, lean and healthy men and women who lived for two weeks at the University of Colorado Hospital, which has a "sleep suite."

They measured how much energy participants used by keeping tabs on the amount of oxygen they breathed in and the amount of carbon dioxide they exhaled.

After all participants spent the first three days with the opportunity to sleep nine hours a night and eating controlled meals meant to maintain their weight, they were split into two groups.

The first group then spent five days with only five hours during which to sleep, while the other group spent those days with nine hours during which to rest.

After the first five days, the groups switched. In both groups, participants were offered larger meals and access to snacks that included ice cream and potato chips but also healthier options such as fruit and yoghurt.

On average, those who slept for up to five hours a night burned five per cent more energy than those who snoozed up to nine hours. However, those with less shut-eye also consumed six per cent more calories.

Those getting less rest tended to eat smaller breakfasts but binged on after-dinner snacks, according to the researchers.

In fact, the late-night food intake totaled more in calories than individual meals, they said.

The authors of the study also found that men and women responded differently to having access to unrestricted amounts of food.

While both males and females put on weight when only allowed to sleep five hours, men gained - even with "adequate" rest - when they could eat as much as they desired. Women, however, maintained their weight when they had "adequate" sleep, no matter how much food was at their disposal.

A separate study out last month said sleep deficit - even just a week's worth -- can have damaging effects on our genes.

Lack of adequate shut-eye had already been linked to conditions from heart disease and cognitive impairment to obesity. (AFP)

Breast milk delivery launched by Midland blood bikes


A charity motorbike breast milk delivery service has been launched to help premature babies.
Midland Freewheelers Emergency Rider Voluntary Service began transporting donated breast milk for babies at Birmingham Women's Hospital on Monday.
The milk is given to sick or premature babies when breast milk cannot be provided by their mother.
The service has about 25 volunteer bikers who transport blood and medical supplies free of charge to hospitals.
It is the first time the charity has delivered milk.

Milk banks

  • The Birmingham Milk Bank was developed by Dr Mary Crosse at Sorrento Hospital, Moseley
  • It celebrated its 60th anniversary in 2010
  • Donor mothers give surplus milk, which is screened and pasteurised
  • There are 17 human milk banks in the UK
Dr Gemma Holder, of Birmingham Women's Hospital, said illness, insufficient supply or separation from the baby could affect a mother's ability to supply breast milk.
Breast milk from a network of donors is used instead as it helps improve the immune system and fight off infections.
She said the milk was "vital to help save the lives of sick or premature babies".
Dr Holder added: "Now we're in partnership with the blood bike charity it means we are able to rely on a swift and constant delivery of the much-needed milk."
Ray Hart, of Midland Freewheelers Blood Bikes, said: "It is vitally important that sick and premature babies get the best possible start in life; our service will enable us to deliver supplies of life-saving breast milk from mother to hospital quickly and efficiently."
He said the charity was appealing for more business sponsors to keep the service free of charge "to help the cash-strapped NHS save money".

threats from Europe's alien invasion


Invasive alien species pose a greater risk to Europe's biodiversity, economy and human health than previously thought, a report has concluded.
The European Environment Agency (EEA) has compiled a list of 28 invaders that highlight the range of threats facing ecosystems in the continent.
Non-native species, such as food crops, can also be beneficial, the study adds.
The reports have been published ahead of a high-level meeting at the European Parliament to discuss the issue.
It is estimated that there are more than 10,000 non-native species in Europe, of which at least 15% are deemed to be "invasive", which are organisms that are known to have negative ecological or economic impacts.
Invasive alien species (IAS) are considered to be one of the main threats to biodiversity, explains EEA executive director Prof Jacqueline McGlade.
"In many areas, ecosystems are weakened by pollution, climate change and [habitat] fragmentation," she says.
"Alien species invasions are a growing pressure on the natural world, which are extremely difficult to reverse."

The report, The Impact of Invasive Alien Species in Europe, lists the various impacts.

"Competition, predation and transmission of diseases between alien and native species are frequent and can pose a major threat to native species," the authors observe.
"Alien species may also affect ecosystem services, which in turn can have an impact on human wellbeing."
One species whose spread and impact has been well documented is Japanese knotweed (Fallopia japonica).
It can reach 4m in height, growing up to 30cm in a day. Its powerful root system can reach depths of three metres into the soil and spread up to 20m, making it almost impossible to eradicate once it becomes established.
The report says the plant forms dense stands and squeezes out other plant species and outcompetes native plants, resulting in a botanical "monoculture".
The publication adds: "The rhizome system of knotweeds can seriously damage infrastructure, such as buildings, river bank stabilisations and water channels, railway tracks and roads, and construction land.
"By disrupting the integrity of flood defence structures, the risk of flooding is increased."
Asian tiger mosquitoThe Asian tiger mosquito is a more direct threat
An IAS that poses a direct threat to human health is the Asian tiger mosquito (Aedes albopictus), which has been linked to the transmission of more than 20 human pathogens, including yellow fever and dengue.
The species is an "aggressive daytime‑biting insect" and its distribution has spread rapidly in western and southern Europe over the past two decades.
On Thursday, Czech MEP Pavel Poc is hosting an event at the European Parliament in Brussels that will look at ways to tackle the threat posed by IAS.
Organised by conservation groups IUCN and Birdlife, the high-level debate at the European Parliament in Brussels will consider measures that could be taken within the EU policy framework to mitigate the present and future threats from invasive alien species.
The EEA report warns that, given the increase in both goods and people moving around the globe, the "number and impact of harmful IAS in Europe may grow significantly in the future".
It adds that changes to the climate may provide opportunities for IAS to proliferate and spread.
"In this situation, some IAS might initiate complex, unpredictable cascades of effects," it warns.
The EEA suggests that the best way to tackle the threats posed by invasive species was through a "combination of preventative measures, early detection and rapid response to incursions, with permanent management only as the last option".
