[Olive oil, immune system and infection]

Area of Science:

• Immunonutrition
• Dietary impact on immune function
• Mediterranean diet

Background:

• Polyunsaturated fatty acids, like n-3, can suppress immune function, aiding inflammation resolution but potentially reducing infection defense.
• Olive oil, a dietary staple, modulates immune responses but preserves host resistance to pathogens.
• Limited research exists on olive oil's role in immunonutrition.

Purpose of the Study:

• To review the immunomodulatory effects of olive oil.
• To clarify olive oil's impact on immune system function, particularly in relation to inflammation and infection resistance.
• To assess olive oil's potential benefits in clinical nutrition for immunocompromised individuals.

Main Methods:

• Literature review on olive oil's effects on immune modulation.
• Analysis of studies investigating olive oil's impact on inflammatory and infectious conditions.
• Synthesis of evidence regarding olive oil's role in immunonutrition.

Main Results:

• Olive oil modulates immune functions beneficially.
• It reduces inflammatory activity associated with autoimmune disorders.
• Crucially, olive oil does not diminish immune protection against infectious agents.

Conclusions:

• Olive oil administration offers health benefits, particularly for the immune system.
• It is a valuable component in clinical nutrition, especially for immunocompromised patients.
• Olive oil supports immune health by reducing inflammation without increasing infection susceptibility.
