American scientists from the University of Texas at El Paso have found substances in coffee grounds that can prevent neurodegenerative changes in the brain, including Alzheimer’s disease and Parkinson’s disease. The study was published in the scientific journal magazine Environmental Research (ER).
Experts have found that caffeic acid from waste ground coffee beans can be used to create so-called carbon quantum dots.
“Caffeic acid-based carbon quantum dots could transform treatments for neurodegenerative diseases. Our goal is to find a treatment by targeting the atomic and molecular bases that drive these conditions,” said Jyotish Kumar, lead author of the study.
Neurodegenerative diseases are primarily characterized by the loss of neurons (brain cells). This suppresses not only a person’s cognitive abilities but also basic functions, including the ability to speak and move.
Neurodegenerative disorders in the early stages and those caused by lifestyle or environmental factors have many features in common. These include increased levels of free radicals and particles containing one or more unpaired electrons. They damage healthy cells by robbing them of electrons and triggering an oxidative reaction.
The team found that carbon quantum dots from coffee protected tissue by scavenging free radicals or preventing oxidation without any significant side effects.
Caffeic acid belongs to a family of compounds called polyphenols. These are plant-derived compounds known for their antioxidant properties. Scientists said caffeic acid is unique because it can penetrate the blood-brain barrier and therefore affect cells within the brain.
