Purpose: To determine the effect of Mediterranean-type diet and close dietetic supervision on dietary antioxidant intake and plasma total antioxidant capacity (TAC) in patients with abdominal obesity. Methods: Ninety subjects with abdominal obesity, 46 in intervention group, 44 in control group, participated in a 2-month, randomized, parallel dietary intervention. All participants were counseled on Greek Mediterranean diet. The intervention group was under close dietetic supervision, followed a specific relevant daily and weekly food plan consuming antioxidant-rich foods and food products. Total dietary antioxidant intake was calculated from the volunteers' food diaries, and plasma TAC using plasma ORAC assay and plasma ferric-reducing antioxidant power (FRAP) assay, both at baseline and at 2 months. Results: Following the 2-month period, total dietary antioxidant intake was increased in the intervention group compared to the control group (P = 0.000). In addition, increased intake of total fat, due to higher consumption of monounsaturated fatty acids, as well as increased intakes of dietary fiber, vitamin C and alcohol was also observed in the intervention group compared to the control group (P < 0.05). Plasma TAC was increased in the intervention group compared to the control group (P = 0.039) using the ORAC assay, while there was a trend toward a TAC increase (P = 0.077) using the FRAP assay. Conclusion: Adherence to a Mediterranean-type diet, with emphasis on an increase in foods rich in antioxidants and close dietetic supervision, can increase total dietary antioxidant intake and plasma TAC in patients with abdominal obesity. © 2012 Springer-Verlag.
