Navigating the Mayo Aisle on a Keto Diet
For many following a ketogenic diet, the creamy, rich texture of mayonnaise is a cherished staple. It's a key ingredient in everything from salads to dips, and its high-fat, low-carb nature aligns perfectly with keto macros. However, the modern grocery store offers a vast and confusing array of mayonnaise products, and not all of them are created equal. Many are filled with cheap, inflammatory oils and hidden sugars that can disrupt ketosis and undermine health goals. Understanding how to read labels is the key to successfully finding a truly keto-friendly option.
The Problem with Conventional Mayonnaise
Traditional mayonnaise is a simple emulsification of egg yolks, oil, and an acidic ingredient like vinegar or lemon juice. The core ingredients are perfectly fine for a keto diet. The problem arises when manufacturers prioritize cost and shelf-life over ingredient quality. Here are some of the ingredients to be wary of:
- Unhealthy Vegetable Oils: The most common oils in conventional mayonnaise are soybean oil and canola oil. These oils are often highly processed and rich in omega-6 fatty acids, which can contribute to inflammation when consumed in excess.
- Added Sugars and Sweeteners: To enhance flavor and appeal, many popular brands add high-fructose corn syrup or other sugars. Even if the nutrition label shows 0g of sugar per serving, a quick glance at the ingredients list can reveal hidden carbs.
- Artificial Preservatives and Additives: Ingredients like calcium disodium EDTA and potassium sorbate are used to extend shelf life but offer no nutritional benefit and are best avoided.
- Blended Oils: Some products are deceptively labeled, claiming to be 'avocado oil mayo' but are actually blended with a larger proportion of cheaper oils like canola or soybean oil.
How to Choose a Keto-Friendly Store-Bought Mayonnaise
Finding a suitable mayo requires becoming a detective in the grocery store aisle. The first rule is to always check the ingredients list, not just the front label. Here are some guidelines:
- Prioritize Healthy Fats: Look for mayos made with oils high in monounsaturated fats, such as 100% avocado oil or high-oleic sunflower oil. Extra virgin olive oil is also an option but can have a strong, sometimes bitter, flavor.
- Ensure Zero Sugar: The ingredients list should not contain any form of added sugar, high-fructose corn syrup, or coconut palm sugar. Many dedicated keto brands proudly advertise their zero-sugar formulas.
- Check for Preservatives: Aim for a simple, clean ingredients list. Preservatives and artificial flavors should be minimal or absent. A shorter, more recognizable ingredient list is always a good sign.
- Confirm the Oil Source: Be wary of misleading labels. A brand might advertise 'made with avocado oil,' but you should confirm that avocado oil is the primary oil used, or that no cheaper vegetable oils are included in the blend.

Making Your Own Keto Mayonnaise
The ultimate way to ensure your mayonnaise is truly keto-friendly is to make it yourself. With just a few simple ingredients, you can create a fresh, delicious, and additive-free condiment in minutes.
A Basic Homemade Keto Mayo Recipe:
- Ingredients: 1 large egg (at room temperature), 1 tbsp lemon juice or apple cider vinegar, ½ tsp Dijon mustard, ¾ cup avocado oil, and salt to taste.
- Instructions: Combine the egg, acid, and mustard in a tall, narrow jar. Using an immersion blender, start blending at the bottom of the jar. Slowly drizzle in the oil until the mixture begins to emulsify and thicken. Once thick, move the blender up and down to fully combine. Season with salt. Store in an airtight container in the fridge for up to a week.
Conclusion
Ultimately, whether store-bought mayonnaise is keto-friendly depends entirely on the brand and ingredients. While the basic composition of mayo is keto-compliant, the addition of cheap vegetable oils, sugars, and preservatives in many commercial products makes them unsuitable for a strict keto diet. Smart shoppers should prioritize brands that use healthy oils like avocado and contain no added sugars. For the utmost control over ingredients, making homemade mayo is a simple and rewarding alternative. Always read the label carefully to protect your health and stay in ketosis.
