Last post I mentioned that I’d show the nutritional difference between regular mayonnaise and non-fat Greek yogurt. Before showing that difference, though, I will say that I’ve used non-fat Greek yogurt not only as a more nutritious substitute but also as a fresh and lively flavor-enhancing alternative to mayonnaise.

Most importantly, when making this comparison – as with any other nutrition label comparison, make sure to check the serving size as circled below.

The serving size listed on the mayonnaise label is 1 tablespoon, or about 1/2 ounce. The serving size for the non-fat Greek yogurt is 1 cup, or 8 ounces. That means you either have to multiply the nutritional values on the mayonnaise label by 16 (there are 16 tablespoons in 1 cup/8ounces) or divide what you see on the non-fat Greek yogurt label below by the same 16 (1 cup = 16 tablespoons).

Below is a table comparing the nutritional values of 1 tablespoon of mayonnaise to 1 tablespoon of non-fat Greek yogurt. The difference is significant!
