Science Daily (November 24, 2009): Polyphenols and Polyunsaturated Fatty Acids Boost the Birth of New Neurons, Study Finds
Universitat Autonoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps to boost the production of the brain's stem cells - neurogenesis - and strengthens their differentiation in different types of neuron cells.
The research revealed that mice fed an LMN diet, when compared to those fed a control diet, have more cell proliferation in the two areas of the brain where neurogenesis is produced, the olfactory bulb and the hippocampus, both of which are greatly damaged in patients with Alzheimer's disease. These results give support to the hypothesis that a diet made up of foods rich in these antioxidant substances could delay the onset of this disease or even slow down its evolution.
The study will be published in the December issue of the Journal of Alzheimer's Disease and was directed by Mercedes Unzeta, professor of the UAB Department of Biochemistry and Molecular Biology. Participating in the study were researchers from this department and from the departments of Cell Biology, Physiology and Immunology, and of Psychiatry and Legal Medicine, all of which are affiliated centres of the Institute of Neuroscience of Universitat Autonoma de Barcelona.
