Background: Adipokines secreted from adipose tissue in obese individuals

increase oxidative stress in the body and sufficient antioxidant consumption is

recommended to reduce the effects of this stress. Consumption of foods rich in

antioxidants is thought to be related to serum total antioxidant capacity (TAC) but

the effect of dietary antioxidant amount on serum antioxidant capacity is not yet

clear. Objective: The aim of this study was to investigate the relationship between

dietary antioxidant intake and serum TAC in obese and normal‑weight individuals.

Methods: Around 36 obese and 24 normal weighted volunteers participated

in this study. Demographic characteristics, anthropometric measurements, and

antioxidant food consumption from frequency questionnaires (questionnaire TAC)

of individuals were recorded. The amount of antioxidant intake from diet (dietary

TAC) was calculated from food consumption records. Serum TAC values

were measured calorimetrically according to the Trolox equivalent antioxidant

capacity (TEAC). Results: The dietary TAC levels of the experimental group were

higher than the control group (5.45 ± 6.15 mmol/day vs. 3.20 ± 7.27 mmol/day,

P = 0.006); whereas, the ratio of serum TAC per body weight was significantly

lower in obese participants (0.013 ± 0.0134 mmol/L vs. 0.017 ± 0.003 mmol/L,

P < 0.001). However, a positive relation (r = 0.339, P = 0.008) was observed

between dietary TAC and serum TAC. Moreover, a positive correlation between

the serum TAC levels of the individuals and the weight in both groups (r = 0.335,

P = 0.046 in obese participants, and r = 0.523, P = 0.009 in control group), and

the BMI in the experimental group (r = 0.384, P = 0.021). Likewise, there is

an association between the diet TAC level and the diet protein ratio (r = 0.478,

P = 0.018) in obese participants. Conclusıon: Dietary TAC intake was significantly

higher and the TAC/weight lower in the experimental group. Moreover, the

relationship between diet TAC and serum TAC was significant.
