Researchers at the University of Lleida (UdL) have discovered that red-fleshed apples improve endothelial function, which regulates blood flow, reduces inflammation, and modulates the immune system in people with high cholesterol.
Laura Rubió, one of the project’s lead researchers, highlighted that the benefits of red-fleshed apples are “superior” due to the significant improvement in inflammation markers. This variety is not grown in Spain, and now researchers are looking for ways to process and commercialize it so consumers can benefit.
The ‘AppleCOR’ project emerged from a collaboration with IRTA, which was testing a red-fleshed apple grown and sold in northern European countries but not in Spain.
This is because red-fleshed apples contain “anthocyanic phenolic” compounds, which are also found in fruits like blueberries and black grapes. These compounds had never been studied at such levels in apples before, and since they are known to have health benefits, the researchers decided to investigate if the same effects occurred in this apple variety.
