“…Tsang et al (2012) announced the elevation in plasma, but not urinary FRAP levels following fruit juice intake. Urinary TAC was also unaltered post 3 weeks consuming of a antioxidants fortified dried fruit and vegetable (Stewart et al, 2002). Vitamin C and magnesium reduce NADPH oxidase as a superoxide‐producing enzyme, which supports that increasing antioxidant capacity can lead to the attenuation of ROS (Lopes et al, 2003, Chen et al, 2001).…”

“…Diet quality has the potential to decrease oxidative stress and inflammation that may be beneficial (Kim et al, 2011; Bärebring et al, 2018). For instance, the consumption of various fruits and vegetables elevated the antioxidant capacity (TAC) of serum, saliva, and urine (Hassimotto et al, 2008; Cao et al, 1998; Jacob et al, 2008; Stewart et al, 2002). However, another study reported that there was no significant effect of following a specific dietary pattern on oxidative stress markers in healthy individuals (Miller III et al, 2005).…”

Diet has the potential to decrease oxidative stress and inflammation and this may be beneficial in several diseases. This study investigated the association between food quality score (FQS) with antioxidant and inflammatory properties in 171 apparently healthy young women. This cross‐sectional study was conducted using a validated food frequency questionnaire to determine the dietary intake of participants. FQS was calculated by summing all the scores obtained from healthy and unhealthy food groups. The total antioxidant capacity and free radical scavenging activity of serum and urine were quantified using the ferric reducing/antioxidant power (FRAP) and α, α‐diphenyl‐β‐picrylhydrazyl (DPPH) methods, respectively. Malondialdehyde (MDA) was measured using the formation of thiobarbituric acid reactive substances (TBARS). White blood cell (WBC) and neutrophil counts, mean platelet volume (MPV) and red blood cell distribution width (RDW), were measured. Neutrophil: lymphocyte ratio (NLR), platelet: lymphocyte ratio (PLR), and RDW: platelet ratio (RPR) were also calculated. A high food quality (rich in fruit and vegetables, nuts, whole grain, and low intake of sweetened beverage, potato chips and fried food from outside the home) was related to lower hematological inflammatory biomarkers including WBC count, RDW, NLR, and PLR. Multivariable‐adjusted odds ratios (95% CIs) demonstrated that higher FQS group (third tertile vs. first tertile) was associated with a significant lower levels of urinary FRAP (ORadj = 0.82; 95%CI: 0.70 to 0.97), and DPPH. High food quality was associated with reduced of markers of inflammation and oxidative stress in Iranian young girl.

“…Helbig et al [ 159 ] reported the same increase in urinary TAC versus baseline with both control bread and bread enriched with black currant press residue (4 weeks). Besides, urinary TAC was unchanged after 21 days consumption of a dried fruit and vegetable extracts fortified with antioxidants [ 176 ], after 2 weeks of Pycnogenol (200 mg/day) supplementation [ 175 ] and after 24 days of administration of an antioxidant mixture containing vitamin E, beta-carotene, ascorbic acid, selenium, alpha-lipoic acid, N-acetyl 1-cysteine, catechin, lutein, and lycopene [ 171 ]. On the contrary, ganoderma lucidum (Lingzhi, woody mushroom) supplements increased urinary TAC both in bolus and in repeated administration [ 177 , 178 ].…”

Total Antioxidant Capacity (TAC) is a biomarker often used in order to investigate oxidative stress in many pathological conditions. Saliva and urine can be collected noninvasively and represent attractive diagnostic fluids for detecting biomarkers of various pathological conditions. The reviewed case-control and intervention studies that measured salivary or urinary TAC revealed that diseases, antioxidant foods, or supplements and age, gender, and lifestyle factors influenced salivary or urinary TAC. Salivary and urinary TAC were particularly affected by oral or renal status, respectively, as well as by infection; therefore these factors must be taken into account in both case-control and intervention studies. Furthermore, some considerations on sample collection and normalization strategies could be made. In particular, unstimulated saliva could be the better approach to measure salivary TAC, whereas 24 h or spontaneous urine collection should be chosen on the basis of the study outcome and of the creatinine clearance. Finally, the uric acid-independent TAC could be the better approach to evaluate red-ox status of body, in particular after nutritional interventions and in diseases associated with hyperuricaemia.
