Margarine is high in fat and doesn't contain sugars.
Remember that fat affects gut motility and can be an additional flareup trigger in some people.
Margarine is a spread used for flavoring, baking, and cooking that was first made in France in 1869. It was created by Hippolyte Mège-Mouriès in response to a challenge by Emperor Napoleon III to create a butter substitute from beef tallow for the armed forces and lower classes. It was named oleomargarine from Latin for oleum (olive oil) and Greek margarite (pearl indicating luster) but was later named margarine.
