## Abstract

The present invention relates to an oil or fat composition containing the following components (A) and (B): (A) from 80 to 99.9 wt. % of a monoglyceride containing 20 to 75 wt. % of docosahexaenoic acid (DHA) and 0.1 to 25 wt. % of icosapentaenoic acid (IPA), as the constituent fatty acids thereof, wherein the weight ratio of DHA/IPA being 2 or more; and (B) from 0.1 to 20 wt. % of a diglyceride.
