Root Explanation

Olestra is a coined term derived from the combination of 'oleo-' (from Latin 'oleum', meaning oil) and 'estra' (a suffix suggesting a chemical compound). The word refers to a synthetic fat substitute that mimics the properties of fat without the calories, thus combining the essence of oil with a chemical structure.

Memory Tip

Think of 'oleo' meaning oil, which helps you remember that olestra is related to a fat substitute that acts like oil but has fewer calories.
