While the Real Mayonnaise uses soybean oil, Duke's also offers a variety of products with different formulations. This is important for consumers looking for alternative fat sources or reduced-fat options.

Duke's Light Mayonnaise: This version also lists soybean oil as a main ingredient. To achieve its "light" status (half the fat and calories of the regular version), it incorporates modified food starch.
Duke's Light Mayonnaise with Olive Oil: This product blends oils to achieve its profile. Its ingredient list specifies "Olive Oil, Canola Oil, Soybean Oil". This means it still contains soybean oil, but in combination with other oils.

However, those with specific dietary restrictions or preferences, such as following a paleo or Whole30 diet, often opt for alternatives made with avocado oil.
