Mayo
“With processed refined soybean oil as the main ingredient in most mayos, there’s nothing healthy about mayonnaise,” says registered dietitian Asvini Mashru, RD, of Wellness Nutrition Concepts in Malvern, Pennsylvania. “Tartar sauce has the same issues as mayo. If you can find a mayo made with 100 percent olive oil instead of soybean oil, this would actually be a healthy choice.” Or make your own mayonnaise for a healthier option.
