Hypothesis
Do common dietary flavonoids inhibit the growth of malaria parasites?
Conclusion
Certain common dietary flavonoids inhibit the intraerythrocytic growth of the 3D7 and 7G8 strains of P. falciparum.
Supporting Evidence
- Eight out of eleven flavonoids tested showed antiplasmodial activity against the 3D7 strain.
- All flavonoids tested showed activity against the chloroquine-resistant 7G8 strain.
- Luteolin was the most active compound against both strains.
- Flavonoid combinations produced an additive antiplasmodial effect.
Takeaway
Some foods like fruits and vegetables contain special compounds called flavonoids that can help stop malaria germs from growing.
Methodology
Flavonoids were tested for their ability to inhibit the growth of two strains of P. falciparum using a [3H]hypoxanthine incorporation assay over 96 hours.
Limitations
The concentrations of diet-derived individual flavonoids in plasma are unlikely to reach those required for complete parasite killing.
