Is Mayo with Avocado Oil Keto?

The Ingredient Breakdown

As a food scientist, I look past the front-of-package claims to the actual formulation. The primary issue with this product for Keto dieters isn't just the oil blend—it's the hidden thickeners.

The first red flag is the inclusion of modified food starch and mustard flour. In standard mayonnaise, the emulsion is stabilized by the egg yolk and vinegar. Adding starch is a cost-saving measure to create thickness without using expensive, high-quality oils or eggs. For a Keto dieter, modified food starch is a source of concentrated carbohydrates that adds up quickly in a serving size.

Furthermore, the oil profile is deceptive. While it contains avocado oil, it is listed alongside canola oil and soybean oil. These are highly processed seed oils that many health-conscious consumers try to avoid. A true 'Avocado Oil Mayo' should ideally list avocado oil as the sole or dominant fat source.

Finally, ingredients like phosphoric acid and calcium disodium edta are used as preservatives and flavor stabilizers. While generally recognized as safe, they indicate a highly processed product rather than a clean, homemade-style condiment.

Nutritional Value

From a macronutrient perspective, this mayo is high in fat, which fits the Keto profile, but the quality of that fat is questionable due to the blend of soybean and canola oils. The real dealbreaker is the carbohydrate count. Because of the added starch and the sugar listed in the ingredients, the net carbs per tablespoon are higher than they would be in a pure avocado oil or homemade version.

For strict Keto, where daily carb limits are often 20g or less, even a small serving of a condiment containing starch can consume a significant portion of your allowance. While it is lower in sugar than sweetened sandwich spreads, the presence of starch makes it a 'dirty Keto' option at best, and a risk for breaking ketosis at worst.
