Experts Demonstrate That Eating Leguminous Plants Reduces The Risk Of Suffering Cancer Of The Colon

27.04.2006


A research group of the Animal Nutrition Unit at Zaidín Experimental Station, which is owned by the Higher Board of Scientific Research, located in Armilla (Granada), have demonstrated that leguminous plants can have beneficial effects on the body. Amongst others, eating these foods can reduce the probability of suffering cancer of the colon, as they reduce the replication ratio of tumour cells.



In collaboration with scientists at Milan University, who had already demonstrated the beneficial effects of soybean proteins for cholesterolemia, the Granada researchers have found that incorporating pulse proteins in the diet of rats reduces the relative weight of the large intestine. This reduction has been associated by other authors with reduced cell proliferation and prevention of cancer of the colon.

On the other hand, the experts have studied the effects of "protease inhibitors", which are present in leguminous plants. These substances inhibit the activity of the enzymes produced by the body to facilitate digestion. Although it could be thought that these might be damaging, according to observations, in normal amounts they have no negative effect on the digestive process. Furthermore, they have been found to have a beneficial effect in respect of certain tumours. These studies will be carried out through an excellence project called Propiedades funcionales y nutricionales de los inhibidores de proteasas de la familia de Bowman-Birk en leguminosas (Functional and Nutritional Properties of Protease Inhibitors of the Bowman-Birk Family in Leguminous plants)
The Granada scientists have demonstrated, in vitro, that the protease inhibitors inhibit tumour cell growth. Other researchers have observed positive effects of these substances in relation to digestive system and mammary gland tumours. These substances have no nutritional effect on the body, but they can prevent cancer, acting as a functional food.



To obtain these results, the scientists separated, by chemical means, the main components (proteins, carbohydrates, fibre) of various leguminous plants, such as broad beans, chickpeas or peas. This separation into food fractions makes it possible to assign a particular effect to an adequately specified food component. The experts give one group of animals a control ration, that is, one for which the nutritional value and its effects are known. At the same time, another group of rodents are offered a ration equivalent to the former, which includes purified fractions. In this way, the substance that has been incorporated into the diet can be linked to the effect produced in the animals.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
