Buying Guide: Key Factors For Keto Mayo Choices
- Oil base matters: Avocado oil and olive oil bases are typically preferred for keto diets due to healthy fats and zero net carbs. Avoid mayo with seed oils like canola or soybean if possible.
- Carbs and sweeteners: Confirm there are no added sugars or high-fructose corn syrup. Most keto-friendly mayos emphasize zero carbs per serving.
- Egg quality: Cage-free eggs are common in premium keto mayos and reflect cleaner ingredient sourcing.
- Storage and shelf life: Large-format jars save money but may require refrigeration after opening. Cold-weather shipping can cause separation; plan accordingly.
- Flavor and texture: Avocado oil mayos tend to be creamier and light in flavor; olive oil may carry a distinct, olive-like finish. Consider how you’ll use them (sandwiches, dressings, sauces).
- Allergen considerations: Gluten-free, dairy-free, and non-GMO claims help with dietary restrictions. Check labels if you have specific allergies or sensitivities.
