Linoleic Acid News and Research

RSS

Linoleic acid (LA) is an unsaturated omega-6 fatty acid used in the biosynthesis of arachidonic acid (AA) and some prostaglandins. It is found in the lipids of cell membranes. It is abundant in many vegetable oils, especially safflower and sunflower oils. It is a colorless liquid.

Compound-level diet analysis sheds light on hidden triggers in IBD

Dutch researchers identified specific food compounds that influence remission and flare risk in patients with inflammatory bowel disease. The study shows compound-level dietary analysis could help personalize IBD management and clarify conflicting advice about diet.
