Several types of unsaturated fatty acids are the dominant component in pumpkin seeds which can play a role in the disease prevention and promote health. Pumpkin seeds also contain the important phytoestrogen compounds, i.e., secoisolariciresinol and lariciresinol that have estrogenic-like effect such as preventing hyperlipidemia and osteoporosis for menopausal women.
