Is Mayonnaise Black Truffle Infused Keto?

The Ingredient Breakdown

As a food scientist, I look at the chemistry of a product to determine its dietary fit. The formula for this mayonnaise is surprisingly clean, particularly for a flavored product. The primary ingredient is mid oleic sunflower oil. This is a heart-healthy fat source that is very low in polyunsaturated fats compared to standard vegetable oils, which is beneficial for reducing inflammation—a key goal for many keto dieters.

The emulsion is created using organic egg yolks and organic whole eggs. Eggs are the gold standard for keto; they provide binding power and fat without any glycemic impact. The acidity comes from organic distilled white vinegar and organic lemon juice concentrate. Both of these are negligible in terms of carbohydrates and are used purely for flavor balance and preservation.

The star flavorings—black truffle oil concentrate and black truffle (tuber melanosporum)—are purely aromatic compounds. Truffles are fungi, not starches, so they contribute savory umami flavor without adding sugar. Finally, the inclusion of organic mustard and organic rosemary extract adds complexity and natural antioxidant properties. There are no hidden starches, thickeners like xanthan gum, or sweeteners in this list.

Nutritional Value

From a macronutrient perspective, this product is a powerhouse for the ketogenic diet. The standard keto macro split requires high fat, moderate protein, and very low carbohydrates. Because this is a pure oil-and-egg emulsion, the fat content is naturally high, providing the fuel your body needs for ketosis.

Crucially, the carbohydrate count is effectively zero. Without added sugars or starchy fillers, the glycemic load of this condiment is negligible. It will not spike your insulin levels or kick you out of ketosis. It is also calorie-dense, which is something to watch if you are strictly counting intake for weight loss, but the satiety provided by the fats can actually help curb cravings for other high-carb snacks.
