Butter

Butter is nearly pure fat — over 700 kcal per 100g, with the majority as saturated fat. It provides vitamin A and small amounts of vitamins E, D, and K2. Used sparingly for flavor, it is generally compatible with a balanced diet; large daily quantities raise LDL cholesterol for many people.

Mayonnaise

Mayonnaise is an emulsion of oil and egg yolk, so it is almost entirely fat and very calorie-dense. The type of oil determines its fat quality; light and olive-oil versions cut calories, and a single tablespoon adds up fast on sandwiches and salads.
