Key Findings: -Roasted peanuts contain 61-114 mg phytosterols (PS)/100g, 78-83% of which is B-sitosterol. Unrefined peanut oil: 207 mgPS/100g (more than unrefined olive oil, which has 145 mgPS/100g). Although refining the oils results in a loss of PS, this loss is greater in olive oil than in peanut oil. Peanut butter: 144-157 mg PS/100g; Peanut flour: 55-60 mg PS/100g
