Mayonnaise does not have any protein due to the fact that while it has eggs in it, only the egg whites are used. All of the protein in eggs comes from the yolks which are not used in the making of mayonnaise whatsoever.
Protein is very important for us to get enough of on a regular basis, so you will definitely want to make sure to eat foods that are high in it. This way you will be able to ensure that you stay healthy as a whole. Eating eggs is a great way to get your daily dose of protein, so make sure you think about including them in your diet a little bit more.
Whoever wrote this is an idiot. Egg whites have a shit-ton of protein, mayo is simply just like 80% oil.
Thank you, Johann. Ridiculous that this is top result on Google. Both egg whites and yolks have protein, but as mentioned, mayo is mostly oil. An entire jar of mayo probably has just 1 or 2 eggs in it, so each serving of mayo has very little of that protein.
