Effect of prebiotic and probiotic foods on health

19.08.2004


A group of researchers at the Public University of Navarre, led by Senior Lecturer in Zoology, Elena Urdaneta Artola, have studied both the mechanisms whereby foodstuffs known as functional act at a gastrointestinal level as well as their possible beneficial effects on the health of individuals.

The study, which will continue until 2006, has received the Ortiz de Landazuri Scholarship for 2004. This is an annual award by the Department of Health of the Navarre Government in recognition of the best project in basic research.

For a number of years now the team has been following a line of investigation on the nutritional modulation of neoplasic and allergic illnesses by means of probiotic and prebiotic foods. Prior to this, they carried out a study on kefir where it was shown that this enhances the digestion of nutrients and their absorption through the digestive tract.



The study is aimed at assessing the physiological, morphological and immunological effects observed in healthy and transgenic experimental animales, produced by various probiotic and prebiotic substances contained in experimental diets.

Amongst the prebiotics being used are quercetine and sphyngolipids. The first is a flavonoid found in most vegetables while sphyngomyelin is found in the cellular membranes of vegetables. With probiotics we find two types of bacteria, Lactobacillus casei and Bifidobacterium bifidum which are present in yoghourts and milk products that are partially fermented.

One of the primary aims of the study is to find out if the probiotic and prebiotic foods have a beneficial effect on healthy persons using the latest techniques in molecular biology and cellular growths.

The second phase consists of growing human cells from biopsies from patients who have undergone gastroscopy – after prior informed permission being requested and granted and prior authorisation of the Committee of Bioethics. The final stage will use highly advanced techniques such as immunohistochemistry.

Moreover, the researchers try to pinpoint the effects these foods have on the prevention of important illnesses such as neoplasic illness, allergies and nutritional intolerance and ailments that have an autoimmune component at a gastrointestinal level.

One of these is cancer of the colon. It has been observed that “the diarrhoeas suffered by cancer of the colon patients diminish on taking probiotics. What they want to study is if these products can also be used to actually prevent the disease.

Finally, another aim of the study is to investigate the immunomodulation through the action of these factors as well as the new lines of biotherapies in order to stimulate the anaerobic flora and lymphatic tissue associated with the intestine and, in this way, stimulate the intestinal immune activity against pathogens.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
