Natural sources
Palmitoleic acid is found in trace amounts in most foods except for sardine oil, which contains 15% of this acid as a component of triglycerides.[1]
Other dietary sources of palmitoleic acid include breast milk,[2] a variety of animal fats, vegetable oils, and marine oils. Avocado oil, Macadamia oil (Macadamia integrifolia), and sea buckthorn oil (Hippophae rhamnoides) are botanical sources with high concentrations, containing 7-12%, 17% and 19-29% palmitoleic acid, respectively.[citation needed].[3][4]
Mink oil is also a source of palmitoleic acid.
