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.

The results showed that the total antioxidant capacity of serum determined as ORAC, trolox equivalent antioxidant capacity (TEAC) and FRAP... increased significantly by 7–25% during the 4 h period following consumption of red wine, strawberries, vitamin C or spinach.

- Human aging is characterized by a progressive increase in oxidative stress, evidenced by decreased plasma antioxidant capacity and increased lipid peroxidation (MDA) and protein oxidation (carbonyls) in erythrocytes.Moderate
- Erythrocyte Plasma Membrane Redox System (PMRS) and Ascorbate Free Radical (AFR) reductase activity increase with age as a compensatory mechanism to maintain plasma ascorbic acid levels and minimize oxidative stress.Moderate
