Mango Consumption and Infection Resistance
Based on the available evidence, mango consumption does not confer resistance to any specific infectious illness in humans. The provided research focuses on mango's metabolic benefits (reducing insulin resistance, hepatic fat accumulation, and oxidative stress) and agricultural disease resistance in mango plants themselves, not human infectious disease resistance 1, 2, 3, 4, 5.
What the Evidence Actually Shows
Human Health Benefits (Not Infection-Related)
The research demonstrates that mango consumption provides:
- Cardiometabolic improvements: Reduced VCAM-1 (vascular adhesion molecule), improved insulin sensitivity, and decreased hepatic fat accumulation 3, 4
- Antioxidant effects: Increased superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) 3
- Intestinal microbiota modulation: Altered gut flora composition in alcoholic liver injury models 1
None of these effects translate to resistance against bacterial, viral, or fungal infections in humans.
Plant Disease Resistance (Not Applicable to Humans)
The agricultural studies show:
- Certain Mangifera species (M. casturi, variety 'Sunny') exhibit resistance to anthracnose fungal disease caused by Colletotrichum species 6
- Bacterial treatments can enhance mango fruit resistance to post-harvest fungal infections 7, 8
These findings relate to plant pathology, not human infectious disease.
Important Clarification
The single reference in the nutrition guideline 9 stating that vitamin A deficiency causes "impaired resistance to infection" refers to the micronutrient vitamin A itself—not mangos specifically. While mangos contain carotenoid precursors to vitamin A, this is a general nutritional principle applicable to any vitamin A source, not a unique property of mangos.
There is no credible scientific evidence that mango consumption confers resistance to any human infectious illness. Claims suggesting otherwise lack support in the medical literature.
