“…We summed all FRAP values of foods reported in the FFQ to estimate the total dTAC of each participant. In order to perform a sensitivity analysis, we also calculated dTAC values, excluding coffee values, as this is a beverage that greatly contributes to dTAC values in our population (13) . We also calculated fgTAC values according to food groups (fruits, vegetables, beans and lentils, oilseeds, dairy products, meats and eggs, pasta, breads and cereals, oils and fats, junk food, natural juices, teas and coffees, artificial juices and sodas, and alcoholic beverages) (online Supplementary Table 1).…”

“…Despite the results obtained so far between nutrient intake and the occurrence of depression, the isolated assessment of antioxidants may not be as effective as the assessment of the interaction of different dietary antioxidants (11) . Therefore, the Dietary Total Antioxidant Capacity (dTAC), an index capable of measuring the global content of dietary antioxidants (12) , has proved to be a helpful tool for investigating the interaction between dietary antioxidants and health outcomes (13)(14)(15) . However, investigations into the relationship between dTAC and depression are still limited, mostly being cross-sectional studies with the Iranian population (16)(17)(18)(19) .…”

This study aims to evaluate the association between Total Dietary Antioxidant Capacity (dTAC) and Total Antioxidant Capacity of food groups (fgTAC) with the incidence of depression in Brazilian graduates participating in the Cohort of Universities of Minas Gerais (CUME Study). The sample consisted of 2,572 participants without a medical diagnosis of depression at baseline who responded to at least one follow-up questionnaire from the CUME project. The Ferric Reducing Antioxidant Power (FRAP) assay was used to determine dTAC. Incidence of depression was estimated by self-reported medical diagnosis of depression during the years of cohort follow-up. Cox regression models were used to relate dTAC and fgTAC to the incidence of depression. The mean follow-up time was 2.96 (1.00) years and 246 cases of depression were observed (32.3/1,000 person years). The mean dTAC was 11.03 (4.84) mmol/d. We found no associations between higher dTAC and lower risk of developing depression after adjusting for possible confounders. The incidence of depression was inversely associated with fgTAC of the beans and lentils group (HR: 0.61; IC0.41 - 0.90). The fgTAC of the Junk food group was positively associated with higher incidence of depression after all adjustments (HR:1.57; IC:1.08-2.26). Our findings do not support an association between dTAC and the incidence of depression in a highly educated Brazilian population. However, associations of fgTAC show the importance of analyzing the food matrix in which these antioxidants are inserted. We highlight the need for more prospective studies with different nationalities to confirm these results.

Dietary total antioxidant capacity and the risk of developing asthenozoospermia: a hospital-based case–control study in China

STUDY QUESTION Is dietary total antioxidant capacity (DTAC) associated with the odds of developing asthenozoospermia in Chinese men? SUMMARY ANSWER There is no statistically significant association between DTAC indices and the odds of developing asthenozoospermia. WHAT IS KNOWN ALREADY Both diet and oxidative stress may be related to sperm quality; however, few studies have investigated the association between DTAC and sperm quality. STUDY DESIGN, SIZE, DURATION This case–control study was conducted from June 2020 to December 2020. Those diagnosed with asthenozoospermia were assigned to the case group, whereas those with normal sperm parameters were assigned to the control group. Data from a total of 553 cases and 586 controls were included in the final analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Men who had been referred to the infertility clinic of Shengjing Hospital of China Medical University were enrolled. Dietary intake was assessed using a validated food frequency questionnaire. DTAC was based on ferric-reducing ability of plasma (FRAP), total oxygen radical absorbance capacity (T-ORAC), hydrophilic oxygen radical absorbance capacity (H-ORAC), lipophilic oxygen radical absorbance capacity (L-ORAC), total phenolics (TP), total radical-trapping antioxidant parameter (TRAP), and Trolox equivalent antioxidant capacity (TEAC). Asthenozoospermia was defined according to the criteria published in the fifth edition of the World Health Organization laboratory manual for the examination and processing of human semen. MAIN RESULTS AND THE ROLE OF CHANCE No significant association was observed between the DTAC indices and the odds of asthenozoospermia after multivariable adjustment (T3 vs T1, odds ratio (OR) = 0.99, 95% CI: 0.73–1.33 for FRAP; OR = 1.05, 95% CI: 0.77–1.42 for T-ORAC; OR = 0.88, 95% CI: 0.65–1.18 for H-ORAC; OR = 0.98, 95% CI: 0.71–1.34 for L-ORAC; OR = 1.03, 95% CI: 0.76–1.39 for TP; OR = 1.18, 95% CI: 0.87–1.59 for TRAP; and OR = 1.15, 95% CI: 0.85–1.55 for TEAC). Both additive and multiplicative interaction analyses suggested that smoking might modify the association of T-ORAC with the odds of developing asthenozoospermia (relative excess risk due to interaction = 0.45, 95% CI: 0.07–0.83, attributable proportion due to interaction = 0.46, 95% CI: 0.07–0.84 for additive interaction; P = 0.033 for multiplicative interaction). LIMITATIONS, REASONS FOR CAUTION Recall bias and protopathic bias were inevitable in this retrospective case–control study. The estimation accuracy of the DTAC indices may have also affected the findings. WIDER IMPLICATIONS OF THE FINDINGS To the best of our knowledge, this is the first study to specifically investigate whether an association exists between DTAC and the odds of developing asthenozoospermia. Although no significant association was found, this study provides novel information pertaining to the fields of nutrition and human reproduction.
