It has long been known that the Mediterranean diet is excellent for our health, especially olive oil. Scientists in the new study have discovered another property of olive oil that has a beneficial effect on health. It is about preserving memory and its ability to protect the brain from Alzheimer’s disease.
Scientists at Lewis Katz School of Medicine at Temple University have published their study in the journal Annals of Clinical and Translational Neurology. They came to the conclusion that cold-pressed olive oil reduces the production of beta-amyloidal plaque and neurofibrillator nodes, which are classic indicators of Alzheimer’s disease.
Professor Domenico Pratico and his team discovered mechanisms behind the protective properties of olive oil. The oil reduces the inflammatory processes in the brain and activates the process of autophagia. In the autophagy process, cells clean up intracellular waste and toxins such as amyloid plaque and tau-poisonous protein that forms nodes in the brain. Mice, which were given cold pressed olive oil, had an increased level of autophagy in the brain cells and a reduced level of amyloid plaque and hyperphosphorylary tau protein, which is responsible for neurofibrillary nodes. Such nodes lead to dysfunction of the nerve cells responsible for the occurrence of Alzheimer’s disease.
The researchers divided animals into two groups. There are huge differences in the appearance and function of brain cells. The connections between neurons “the so-called” – The synapses were better preserved in mice to which olive oil was given, and there was an increase in the process of autophagia. They also showed better memory
This discovery is of great importance because scientists believe reduced autophagy marks the onset of Alzheimer’s disease. They want to continue research and discover if olive oil can really help treat and prevent this disease, even though it has already occurred in the body.and learning ability.
