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: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
