As a coffee lover and someone with a family history of cardiovascular disease, this research article immediately caught my attention. We all know that according to the CDC, heart disease is the number one killer of Americans. Elevated low-density lipoprotein (LDL), the bad cholesterol, is a major cause of heart disease. LDL causes the build-up of fatty deposits within arteries, reducing and sometimes eventually blocking the flow of blood and oxygen needed by our hearts. This can cause a heart attack. Several foods have been shown to modify LDL cholesterol levels which is what excites me about good nutrition. This particular research study, a new meta-analysis, compiled evidence from serval studies. The findings were that the brewing method of coffee has an influence on LDL levels! Just like a good friend filtered is good, unfiltered is not.
What does this boil down to? Drinking unfiltered coffee is not recommended for your cardiovascular health. Unfiltered coffee contains high levels of chemicals that impede lipid-protein metabolism. This means coffee preparations like the French press and fancy coffee machines at cafes and restaurants that don’t use filters have a high number of these chemicals in their cups of Joe. Luckily, for coffee lovers like me, these chemicals called diterpenes are easily removed from our favorite brew by using a paper filter, so enjoy your Americano filtered.
My other takeaway? In looking at the study’s picture graph (above) I can continue to enjoy my avocados in everything, keep added sugars to a minimum, and continue to avoid saturated fats to take care of my heart.
