How the hell do these go together?

That is not mayo ......see that "olive oil" disclaimer on the jar ....

translation: This is some nasty ***, greasy stuff that is packaged to appear like and fool some into thinking its mayo, but its NOT

if it were real mayo, I would be on board, but the olive oil makes me freak out and put up defense.

Actually, "real Mayo" is made with olive oil. The truth is that the type of oil doesn't really matter. Hellman's uses soy bean oil but true homemade mayo served in fine restaurants uses extra virgin olive oil. The "Light" part is what really makes the difference in composition.

Believe it or not, there's a standard of identity for mayo. Mayonnaise, as defined by the U.S. Food and Drug Administration must contain vinegar, egg or egg yolks, and at least 65% oil by weight. It may contain spices and natural seasonings except turmeric and saffron, since yellow color might suggest added egg yolk.

Therefore, anything that does not meet this requirement cannot be marketed in the US as real "mayonnaise".

Reduced fat mayos (called 'dressings'), do not have the same amount of oil (necesary to meet the standard). Since they reduce the amount of oil to reduce the calories, they replace it with extra water emulsified in using food grade stabilizers to mimic the oil. These stabilizers are just the same natural stabilizers (surfactants) contained in an egg that stabilizes the 'real' mayo. The just add it by itself without adding more eggs. People just don't recognize the chemical names or descriptions and think they are evil lab-created chemical monstrosities...but they aren't. It's just more of the same stuff that's already in an egg.

It's kinda like how some people would never drink from a bottle of liquid labeled "Di-hydrogen oxide distillate" but wouldn't have any issue if it's labeled with the more common name of..."water".
