The present invention addresses the problem of providing, from among components recognized as safe on the basis of food-usage experiences, a composition having an anti-inflammatory effect. Based on the fact that soybean protein isolates have an anti-inflammatory effect in some cases, phospholipids that act as the action bodies, which are obtained from the soybean protein isolates by means of alcohol extraction, were found. Through more detailed investigations, among the phospholipids, one that has PI as an essential component, that additionally contains another phospholipid, and for which the "[sum of PC, PE, and PS]/[amount of PI]" ranges from 0.05 to 2.6 was found to have an IL-1β-production suppressing effect. Such a composition is recognized as safe on the basis of abundant food-usage experiences, and thus, the problem of the present invention was solved. |
