When talking about this common condiment, many people note the fat content found in mayo as the main reason why they think it's unhealthy. Mayo is usually made up of eggs, vinegar or lemon juice, oil, and mustard (via Verywell Fit). While it is true that one tablespoon of mayonnaise contains 10 grams of fat and 94 calories, it is primarily composed of unsaturated fat, a type of healthy fat. Unsaturated fats have been found to lower inflammation and cholesterol as well as support steady heart rhythms (via Harvard School of Public Health).

Of course, consuming a high amount of fat on a regular basis is never a good idea. There are versions of mayo available that contain avocado or olive oil instead of the typical soybean oil it usually contains and that improves the nutritional component a bit.

When enjoyed in moderation, you can safely consume regular mayo during pregnancy as long as you follow some simple rules.
