Kiwifruit better than vitamin C tablets

The Press
28/05/2011














Kiwifruit is a much better source of vitamin C than supplements, Christchurch researchers have found. Otago University Christchurch investigated kiwifruit as a source of vitamin C and found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplements form.

The study has been published in The American Journal for Clinical Nutrition, the highest-ranking journal for human nutrition research. Lead researcher Associate Professor Margreet Vissers said people needed vitamin C in all body tissues and organs. Because people's bodies could not make the vitamin, they had to get it from food. Vitamin C is also available in purified form and is one of the most commonly consumed vitamin supplements.

Mice fed kiwifruit absorbed vitamin C much more efficiently than those given the purified supplement form, and retained it for longer. Vissers said this suggested that there was something in the fruit that improved absorption and retention. "The findings of the mouse trial have important implications for human nutrition," she said. A human trial was under way. "The question that has often been asked is whether a supplement is as good a source of vitamin C as whole foods, but few studies have addressed this issue," Vissers said.

The mouse study was funded by Zespri and Otago University.

Ai Weiwei: the reasons behind his arrest?

On a clear and bright day last November, a few hundred of Ai Weiwei’s fans gathered on the outskirts of Shanghai for a party. A flash mob, they came from all over China after Ai issued an invitation over the internet to mock the local government. They feasted on crabs at long trestle tables, sang protest songs and felt they had scored a point against the Communist party officials that had solicited Ai, as a famous artist, to build a new studio in Shanghai and then turned around and ordered him to knock it down when his activism burned too brightly.

It was a happy day, but there was a price to pay. A few days later, the police knocked on the door of Ai’s Beijing home. They told him he was “very close to going to jail”. The response was characteristic of an artist who has increasingly incorporated activism into his art. “I hope it doesn’t come to that. But I’m ready for it, because I believe the core value of an artist must be to express yourself freely and fight for the freedom of others.”


Unlike many of China’s other activists, who have never been heard of inside China because of the country’s pervasive censorship, Ai Weiwei is a celebrity. The son of a revered poet, Ai Qing, Ai comes from the Communist party’s equivalent of the aristocracy.

For years, he has been shielded by his fame and by his family connections. His father was standing next to Chairman Mao on the podium in Tiananmen Square when the People’s Republic of China was founded in 1949.

Wen Jiabao, the Chinese premier, quoted Ai Qing’s poetry at a press conference four years ago when he was asked how China would make its people happy. “You may ask: what do you mean by being happy?” Wen said. “Let me quote a line from Ai Qing: ‘Go and ask the thawing land, go and ask the thawing river’.”

Since China emerged from isolation 30 years ago, there has been a continual and lasting thaw. But in the last few years, since the Beijing Olympics, the mood has become less optimistic. Encouraged and empowered by their success in delivering a smooth Olympic games, China’s security apparatus has steadily expanded. The budget for security is more than 50 per cent higher than it was during 2008, the year of the games, and has now even outstripped the budget of the People’s Liberation Army.

As China’s current leaders prepare to hand over power to their successors in 2012, the hardliners within the Communist party seem to have moved decisively to the forefront. Over the past few months, perhaps unnerved by popular revolts elsewhere, Chinese security officials have detained or threatened scores of activists, Christians and lawyers.

At times it has appeared to be a carousel of intimidation, with lawyers being dragged in, threatened and released only for others to take their place in the cells. Against this backdrop, Ai Weiwei is perhaps the party’s biggest scalp. While his protests have become steadily more electric over the past few years, few expected that any action would be taken against him.

There are echoes of history in his detention, however. His father, Ai Qing, said in 1946: "I believe that art and the revolution must go together; they can never be separated. We are political animals, and sometimes we write as political animals. If the revolution fails, the art will fail, but in as far as is possible the artist must be a revolutionary. As a revolutionary and as an artist he must represent his times.”

Partly because of his strong opinions, Ai Qing was exiled in 1958, when his son was just a year old, to the Gobi desert in the far west province of Xinjiang. In the madness of the Cultural Revolution, Ai Qing was forced to clean public toilets while his son worked in the fields. Only after Chairman Mao died was he rehabilitated. In a letter from 1978 that Ai’s elder sister recently released, the artist described those early days.

"We drifted on a small boat for 20 years," Ai wrote. "If I say the past time left me with some memorable things, it has no mystical and magnificent sky, no beautiful and moving fairy tales, no endless warmth of home, no colourful flower, no graceful music."

"What is deeply imprinted on my mind is: on the smoking dried land the slim and weak child carried heavy firewood; the zigzag footprints left in the cold wind and the blind nights; the sound of smashing furniture and people begging for mercy; the cat being hanged till it was dead and mudfish heads reaching out from the pond; the bullying and cursing in front of people. We were so young but we had to bear all the crimes," Ai wrote.

"If I can say I have some valuable things, those are my memories. Memories of the endless muddy road, the wild Gobi Desert without any sign of people. The bottomless memory poisoned our young souls like snakes, but we didn't die in it. On the contrary, I want a better life for myself to control my own destiny.”

For Ai, his detention is the price of his artistic endeavour and his determination to take action. “I do not believe in so-called intellectuals,” he wrote in 2009. “I disdain the fact that they only think rather than turning their thoughts into action.”

For the government, it is unclear why they have chosen to act now, after years of tolerating Ai’s dissent. While Chinese officials talk of wanting to use “soft power” to show China’s progress, the hardliners who appear to be in the ascendancy have perhaps underestimated the global power of Ai’s art.

Brain scans reveal the power of art

Works of art can give as much joy as being head over heels in love, according to a new scientific study. Human guinea pigs underwent brain scans while being shown a series of 30 paintings by some of the world's greatest artists. The artworks they considered most beautiful increased blood flow in a certain part of the brain by as much as 10 per cent – the equivalent to gazing at a loved one.

Paintings by John Constable, Ingres, the French neoclassical painter, and Guido Reni, the 17th century Italian artist, produced the most powerful 'pleasure' response in those taking part in the experiment. Works by Hieronymus Bosch, Honore Damier and the Flemish artist Massys – the 'ugliest' art used in the experiment – led to the smallest increases in blood flow. Other paintings shown were by artists such as Monet, Rembrandt, Leonardo da Vinci and Cezanne.

Professor Semir Zeki, chair in neuroaesthetics at University College London, who conducted the experiment, said: "We wanted to see what happens in the brain when you look at beautiful paintings. "What we found is when you look at art – whether it is a landscape, a still life, an abstract or a portrait – there is strong activity in that part of the brain related to pleasure. We put people in a scanner and showed them a series of paintings every ten seconds. We then measured the change in blood flow in one part of the brain. The reaction was immediate. What we found was the increase in blood flow was in proportion to how much the painting was liked. The blood flow increased for a beautiful painting just as it increases when you look at somebody you love. It tells us art induces a feel good sensation direct to the brain."

The test was carried out on dozens of people, who were picked at random but who had little prior knowledge of art and therefore would not be unduly influenced by current tastes and the fashionability of the artist. The magnetic resonance imaging (MRI) scan measured blood flow in the medial orbitofrontal cortex, part of the brain associated with pleasure and desire. The study, which is currently being peer reviewed, is likely to be published in an academic journal later this year. Professor Zeki added: "What we are doing is giving scientific truth to what has been known for a long time – that beautiful paintings makes us feel much better. But what we didn't realise until we did these studies is just how powerful the effect on the brain is."

The study is being seized upon as proof of the need for art to be made as widely available to the general public as possible. There is currently concern in the arts world that widespread budget cuts could affect accessibility while also slashing acquisition budgets. "I have always believed art matters so it is exciting to see some scientific evidence to support the view life is enhanced by instantaneous contact with works of art," said Dr Stephen Deuchar, director of the Art Fund, the national fund-raising charity which has spent £24 million over the last five years helping to buy art for galleries and museums.

Last month, the organisation launched a National Art Pass giving free entry to more than 200 museums and galleries and 50 per cent off entry to major exhibitions. The Art Fund has pledged to increase its funding by 50 per cent to £7 million a year by 2014 to make up for widespread budget cuts in the arts world. The charity has been praised by Culture Secretary Jeremy Hunt for showing that "philanthropy can be about small as well as large donations".

YikeBike pedalling new product

Peter Higgins and Lincoln Sell from YikeBike with their hi-tech award for the best hardware product they earned at the NZ Hi-Tech Awards. The Christchurch company that developed the electric folding YikeBike has just launched a new Fusion model.

The Christchurch company that developed the electric folding YikeBike has just launched a new Fusion model – a slightly heavier version of the original carbon fibre bike but a bit lighter on the pocket.

Chief technology officer Peter Higgins said the Fusion model would be a standard version for distributors, while the carbon fibre bike would be the high end version, sold online via YikeBike's website. The main difference is the Fusion frame and structural parts are made from alloy and reinforced polymer composite, while the original is made from carbon fibre. "So you will end up with a bike that looks very similar at a lower price point, 3kg heavier," Higgins said. The Fusion weighs about 14kg compared to the 10.8kg of the carbon fibre bike. The Fusion will cost just under US$2000 (NZ$2500), cheaper than the carbon fibre version at around US$3000.

The company developed the Fusion model because there was strong interest in the original YikeBike but at a lower price point, and people wanted to be able to buy the bike through a distributor so they could go and see the product and test it, Higgins said. The Fusion model would meet that demand. The company had not been too hard hit by the February 22 earthquake which struck Christchurch, Higgins said, and staff had been able to zip around the city's streets more easily on their YikeBikes than in their cars due to damaged roads and traffic congestion.

The first version had been bought by "early adopters" – people who like to have the latest in cool new stuff. The bikes were first sold in August and September last year and since then the company has sold about 250 carbon fibre YikeBikes, including to local software company Hairy Lemon. Other customers include Google and Jackie Chan.

The company, founded by serial entrepreneur Grant Ryan, has recently picked up the Dell Innovative Hi-Tech Hardware Product Award at the NZ Hi-Tech Awards. The judges said the YikeBike was innovative at both a concept and execution level, with a market driven approach to product development, with sound plans to drive mass market adoption. The more affordable Fusion model may be part of the mass marketplans. The bike was ranked 15th in Time magazine's top 50 inventions of 2009 and while the United States is currently the biggest market for the bike its customers span the globe – from New Zealand to Finland, Abu Dhabi, Singapore and Brazil.
