  2. It has high levels of sodium (a little more than 150 milligrams per tablespoon). This can be problematic if you have heart disease or hypertension, among other health conditions.

So should you avoid all types of mayonnaise? No. Just make sure to choose lower-fat varieties as they’ll still provide the same nutrition benefits but contain fewer calories and less sodium per serving size.
