TI  - Development and validation of a food frequency questionnaire for the assessment 
      of dietary total antioxidant capacity.

AB  - The total antioxidant capacity (TAC) of the diet may be an important tool to 
      monitor the protective effect of plant foods in epidemiological studies. We 
      developed a semi-quantitative FFQ for the assessment of dietary TAC by 3 
      different assays, i.e., Trolox equivalent antioxidant capacity (TEAC), total 
      radical-trapping antioxidant parameter (TRAP) and ferric reducing-antioxidant 
      power (FRAP). The FFQ consists of 53 questions about the major sources of dietary 
      TAC in Northern Italy and was validated against a 3-d weighed food record (3D-WR) 
      in 285 individuals (159 males and 126 females) aged 35-88 y and living in the 
      province of Parma (Italy). Plasma TAC was also evaluated in a subgroup of 
      subjects using the TEAC and FRAP assays. The FFQ was associated with 3D-WR 
      (quadratic-weighted kappa = 0.49 for TEAC, 0.53 for TRAP, and 0.49 for FRAP; P < 
      0.0001) and proved reasonably accurate to classify individuals into quartiles of 
      TAC intake. The FFQ had a good repeatability when readministered after 1 y in 55 
      subjects (quadratic-weighted kappa for intertertile agreement = 0.66 for TEAC, 
      0.70 for TRAP and 0.68 for FRAP; P < 0.0001). With both dietary instruments, the 
      main contributors to TAC intake were coffee and tea in women and alcoholic 
      beverages in men, followed by fruits and vegetables in both sexes. Plasma TAC and 
      dietary TAC were not associated. In conclusion, our FFQ has the potential for 
      being used to rank subjects on the basis of their antioxidant intake as 
      determined by dietary TAC in large epidemiological studies. The FFQ should be 
      validated in external populations before being used for research purposes.
