The Prophet said
كلوا الزيت وادهنوا به
In this hadith narrated by at-Tirmidhiyy, the Prophet urged us to eat olive oil and anoint our bodies with it.
Some of olive oil's health benefits:
- Regular consumption helps lower both systolic and diastolic blood pressure (as shown in recent studies)
- Lowers the level of total blood cholesterol, LDL-cholestrol, and triglyecrides
- Rich in antioxidants, especially Vitamin E (long thought to minimize the risk of cancer)
