Nocellara del Belice table olives: A 30-day intervention study on the effects of MUFA-rich green table olives

BMC Complementary and Alternative Medicine.

2016

Study Details:

• Daily table olive consumption (12 MUFA-rich green table olives - Nocellara del Belice variety)

• 30-day intervention period

• Participants: Healthy adults

• Measured: Oxidative stress markers, inflammation markers, liver function, kidney function, lipid values

Key Findings:

• Antioxidant Effects: Significant reduction in malondialdehyde (oxidative stress marker)

• Anti-inflammatory Effects: Significant decrease in interleukin-6 (IL-6), a key inflammation marker

• Safety: No detrimental effects on liver function, kidney function, or lipid values

• Nutritional Benefits: Effects attributed to monounsaturated fatty acids (oleic acid) and phenolic compounds (oleuropein, hydroxytyrosol, tyrosol)
