New studies on goat milk show it is more beneficial to health than cow milk

31.07.2007
Research carried out at the Department of Physiology of the University of Granada (Universidad de Granada [http://www.ugr.es]) has revealed that goat milk has more beneficial properties to health than cow milk. Among these properties it helps to prevent ferropenic anaemia (iron deficiency) and bone demineralisation (softening of the bones).

This project, conducted by Doctor Javier Díaz Castro and directed by professors Margarita Sánchez Campos, Mª Inmaculada López Aliaga and Mª José Muñoz Alférez, focuses on the comparison between the nutritional properties of goat milk and cow milk, both with normal calcium content and calcium enriched, against the bioavailability of iron, calcium, phosphorus and magnesium. To carry out this study, the metabolic balance technique has been used both in rats with experimentally induced nutritional ferropenic anaemia and in a control group of rats.

In order to know how the nutritive utilisation of these minerals may affect their metabolic distribution and destination, the UGR researcher has determined the concentration of these minerals in the different organs involved in their homeostatic regulation and different haematological parameters in relation to the metabolism of the minerals.

Better results with goat milk

Results obtained in the study reveal that ferropenic anaemia and bone demineralisation caused by this pathology have a better recovery with goat milk. Due to the higher bioavailability of iron, calcium, phosphorus and magnesium, the restoration of altered haematological parameters and the better levels of parathyroid hormone (PTH), a hormone that regulates the calcium balance in the organism was found in the rats that consumed this food.

Javier Díaz Castro points out that the inclusion of goat milk with normal or double calcium content in the diet “favours digestive and metabolic utilisation of iron, calcium and phosphorus and their deposit in target organs - parts of the organism to which these minerals are preferably sent - involved in their homeostatic regulation”.

According to this researcher, all these conclusions reveal that regular consumption of goats’ milk – a natural food with highly beneficial nutritional characteristics - “has positive effects on mineral metabolism, recovery from ferropenic anaemia and bone mineralisation in rats. In addition, and unlike observations in cow milk, its calcium enrichment does not interfere in the bioavailability of the minerals studied”.

Although there is no doubt that these findings may be a base for further in depth study of the multiple health benefits of goat milk, the UGR [http://www.ugr.es] researcher warns that “studies in humans are still required in order to confirm the findings obtained in rats and to promote goats’ milk consumption both in the general population and in the population affected by nutritional ferropenic anaemia and pathologies related to bone demineralisation”. Part of the results of this research has been published in the prestigious scientific journals International Dairy Journal and Journal Dairy Science.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
