Dietary intake of antioxidants (strawberries, spinach, red wine, vitamin C) significantly increases serum total antioxidant capacity (ORAC, TEAC, FRAP) within 4 hours of consumption.

Consuming antioxidant-rich foods like strawberries, spinach, or red wine can boost your blood's antioxidant capacity for a few hours. However, this is an acute effect and does not replace the need for long-term healthy habits.
