They protect the endothelium, which is the thin layer of cells that lines the arteries, from damage caused by free radicals and inflammation. This ensures the smooth flow of blood throughout the body, reducing the risk of blood clots. Hence, including purple onions in one’s diet can promote heart health and reduce the risk of various cardiovascular diseases.

Moreover, purple onions do not require many pesticides, contributing to a healthy ecosystem and reducing the number of chemicals used in farming. Purple onions also have a long shelf life compared to other vegetables, which reduces food waste and encourages more sustainable agricultural practices. Therefore, purple onions play a vital role in creating a more eco-friendly and sustainable food system.
