Duke’s Mayonnaise On Keto Diet: What You Need To Know

Mayonnaise is a stable emulsion that is made with egg yolk, an acid- such as vinegar or lemon juice and oil. Sometimes other seasonings are added to create a unique product. It is used as a base for other sauces, as well as on sandwiches, salads and other dishes. 

Every brand has its own type of mayonnaise that can vary in consistency and color. The color of mayo can vary from near-white to pale-yellow and the texture can be from a light cream to a thick gel-like consistency.

Duke’s Mayonnaise is one of my favorite mayos on the market and the third-largest brand of mayo in the US. It is known as the mayo that contains more egg yolks than any other on the market. But, does that mean that it is keto-friendly? Keep on reading to find out.

What is Duke’s Mayonnaise?

Duke’s Mayonnaise is a brand that produces condiments and it was created in 1917 by Eugenia Duke in Greenville, South Carolina when she started selling sandwiches with her homemade mayo to soldiers. In 1923 they started selling the mayonnaise as a separate product.  

On February 29th, 1929, Eugenia decided to sell their products to C.F. Sauer Company. And the Duke’s products became their signature and most famous product. 

Even though it is the third-largest mayonnaise brand in the United States, it was first largely sold mainly throughout the South. In 2017, 100 years after its creation it became available throughout the United States, and Australia, New Zealand, and the Middle East.

In 2019, after 132 of private ownership, Duke’s Mayonnaise was bought by Falfurrias Capital Partners of Charlotte, North Carolina.

All Duke’s products are GMO-free, gluten-free and kosher. 

How many products does Duke’s have?

There are 5 different condiments created by this brand and those are Real Mayonnaise, Light Mayonnaise, Light Mayonnaise with Olive Oil, Tartar Sauce and Sandwich Relish.

Can You Eat Duke’s Mayonnaise On The Strict Keto Diet?

Duke’s products are low-carb, gluten-free, GMO-free and kosher, and they are known to be somewhat healthier than others on the market. If you look at the table of nutritional facts per serving, all Duke’s products have minimal carbs or even 0 carbs.

While that may seem like a great thing for people who are following a keto diet, if you look in the ingredients list, you’ll notice ingredients like sugar, modified food starch, soybean oil and corn sweeteners which are things that are usually avoided on a (strict) keto diet.

Therefore, Duke’s products are not a great option if you are on a strict keto diet, but they can be consumed by those on a low-carb diet, regular diet or those looking to just reach daily carb limits.

We’re hoping for Duke’s to produce a keto mayo line which includes strict keto ingredients such as avocado oil.

Where To Buy?

You can find Duke’s Mayonnaise and other Duke’s products in common grocery stores and you can also find them online on sites like Amazon.com. You use the store locator in the “Where to buy” section on their site if you want to know where you can find it near you. 

Bottom Line

Is Duke’s mayo strictly keto-friendly?

No, Duke’s Mayo is not strictly keto-friendly as it contains non-strict ketogenic ingredients such as starch, sugar, soybean oil and canola oil. However, it can be incorporated into a low-carb diet. 

How many net carbs does Duke’s Real Mayo have?

Duke’s Real Mayonnaise doesn’t have any net carbs. 


If you are not on a strict keto diet and you are okay with consuming highly-processed food with some ingredients that are not keto-friendly, then you can fit Duke’s products in your daily calories. They are a great choice if you want to add additional flavor to add to any of your dishes.
