Introduction : This study aimed to investigate the relationship between Med-Diet adherence with sustainable nutrition and environmental footprints in academicians. Methods : The study involved 153 academicians aged 23-64 working in a university in Turkey. Data were collected through a questionnaire including socio-demographic characteristics, anthropometric measurements, Mediterranean Diet Adherence Scale (MEDAS) and Sustainable and Healthy Eating Behaviours Scale (SHEBS). Carbon and water footprints were calculated. Results : All sub-scales of SHEBS were higher in individuals who adhered to Med-Diet than those who did not (p<0.05). The carbon and water footprints of individuals with high adherence to the Med-Diet were lower than those of no adherence (p<0.05). Each 1-point increase in MEDAS score was associated with a 1-point increase in SHEBS score, a 0.15 CO2 eq/kg and a 0.001 m3/year decrease in the amount of carbon and water footprint of food. Conclusion : Higher adherence to the Med-Diet was associated with higher sustainable nutrition behaviours, and lower environmental footprints.

This study aimed to examine dietary antioxidant and serum antioxidant capacity in patients with knee osteoarthritis (OA). This case-control study consisted of 47 patients with OA (case group) and 30 healthy subjects (control group). The control and case group were matched age, gender, and body mass index (p > 0.05). A food frequency questionnaire was administered to participants, and dietary total antioxidant capacity (DTAC) was estimated using the ferric reducing antioxidant power method (FRAP). Participants' serum total antioxidant capacity (TAC) and total oxidant capacity (TOC) measurements were performed, and the oxidative stress index (OSI) was calculated. DTAC of case group was found to be lower than the control group (p < 0.05). The daily consumption of red meat and butter of the individuals in the case group was higher than that of the control group, and their fish consumption, dietary vitamin A and carotene intakes were found to be lower (p < 0.05). In addition, OA patients have TAC and OSI was also found to be significantly higher than in control group (p = 0.001 and p < 0.001). Since low dietary total antioxidant capacity and high serum total oxidant capacity, individuals with OA should pay more attention to their diet to increase serum antioxidant status., (© 2024.

Objectives: This study aims to investigate the relationship between disease activity, dietary phytochemical index (DPI), and serum total oxidant status (TOS) and total antioxidant status (TAS) in patients with ankylosing spondylitis (AS)., Patients and Methods: Between August 2020 and January 2021, a total of 37 patients (23 males, 14 females; mean age: 39.3±9.4 years; range, 21 to 61 years) with AS and 36 age-, sex-, and body mass index-matched healthy individuals (24 males, 12 females; mean age: 37.9±8.9 years; range, 20 to 60 years) were included. Serum TAS (μmoLTroloxEq/L) and TOS (μmoL H2O2Eq/L) measurements were performed and the oxidative stress index (OSI) was calculated. Dietary evaluation was made from a one-day dietary record and DPI was calculated., Results: Serum TAS level in AS patients was significantly lower than the healthy group (p=0.003). Serum TOS level was similar in both groups. The OSI of patients was significantly higher than the controls (p=0.035). The mean DPI, polyunsaturated fatty acid, n-3 fatty acid, and vitamin C intake of patients were significantly lower than controls (p=0.042, p=0.033, and p=0.022, respectively). A moderate positive correlation was found between the TAS level and DPI of the control group (r=0.352, p=0.035). According to medications, no significant difference was seen between the groups in terms of patients' characteristics, DPI, and laboratory tests and there was no correlation between DPI, TAS, TOS, and OSI., Conclusion: Lower DPI and lower n-3 fatty acid and vitamin C intake in patient group demonstrated that patients with AS should pay more attention to their diet to increase serum antioxidant status., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2022, Turkish League Against Rheumatism.)
