Women's nutritional habits better for the environment

03.04.2012
When it comes to the question of which eating styles are kinder on the environment, women come off far better. This has been shown by studies carried out by scientists at the Martin Luther University Halle-Wittenberg, Germany.

Based on representative food consumption and production data, they compared the environmental impacts of various eating styles.

They took results from the last National Nutrition Survey, which in 2005 and 2006 saw around 20,000 people in Germany interviewed in great detail with regard to their eating habits, and evaluated these from a nutritional ecology perspective.

In terms of impacts on the greenhouse effect, ammonia emissions (by way of fertilizers) and the amount of land required, it was the average nutritional pattern of women which demonstrated clear advantages, resulting from lower proportions of those foods whose production is more of a burden on the environment. These mostly include animal products, in particular beef and veal as well as butter and pork.

“If all the men in Germany were to adopt the typical consumption profile of women, whereby their consumption of meat and sausage products would be reduced by around a half and these would be replaced by higher levels of vegetables, fruit and cereal products, this would free up an area at home and abroad of approximately 15,000 square kilometres.
That's slightly larger than Northern Ireland ” explains study leader Toni Meier of the Department of Agronomy and Organic Farming at the Martin Luther University. “What’s more, greenhouse gas and ammonia emissions would be cut by about 15 million and 60,000 tonnes respectively.”

In Germany, food is estimated to be responsible for about 20 per cent of the overall greenhouse effect. “With regard to ammonia, food consumption is actually responsible for 95 per cent of all emissions,” points out Toni Meier. “Our results make it clear that, depending on the proportion of the overall effect, the potential impact had by dietary shifts could vary considerably. Women’s nutritional habits may serve as a good example.”
The researchers from Halle have published their findings in the “International Journal of Life Cycle Assessment”:

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
