Food consumption based on the nutrient profile system underlying the Nutri-Score and renal function in older adults.

BACKGROUND: The impact of the Nutri-Score labelling system on renal function is unknown. OBJECTIVE: To assess the association between food consumption based on the nutrient profile system underlying the Nutri-Score and renal function decline in older adults. METHODS: We used data from the Spain-based Seniors-ENRICA cohort, a study with 1312 community-dwelling adults aged ≥60 years recruited during 2008-2010 and followed up to December 2015. At baseline, a validated dietary history was obtained. Based on their nutritional quality, foods consumed were categorized into five labels (A/Green-best quality, B, C, D, E/Red-worst quality) using the established Nutri-Score algorithm. For each participant, a Nutri-Score dietary index (DI) was calculated in g/day/kg of weight. At baseline and at follow-up, measured serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) levels were obtained, and time changes were calculated. A combined outcome for renal decline was defined as: any increase in SCr or any decrease in eGFR beyond expected-for-age. Statistical analyses were performed with logistic regression adjusting for socioeconomic, lifestyle, total energy intake, fresh foods, and comorbidity confounders. RESULTS: A total of 183 cases of renal-function decline occurred over a mean 6-year follow-up. Participants with a higher (less favorable) Nutri-Score DI (interquartile range (IQR)13.2-17.7 (g/day/kg of weight); 46 cases) had higher probability of renal decline than those with a lower Nutri-Score DI (IQR 36.6-46.2; 44 cases); the corresponding odds ratios (95% confidence interval) across increasing quartiles of Nutri-Score DI were 1 (reference), 1.26 (0.78-2.04), 1.55 (0.92-2.62), and 1.82 (1.01-3.30), P-trend = 0.045. Per each 10-point increase in the Nutri-Score DI the odds of renal decline increased by 27% (6%-52%). CONCLUSIONS: Higher Nutri-Score DI, reflecting the consumption of foods with less favourable Nutri-Score rating, was associated with higher kidney function decline in older adults. Consequently, Nutri-Score labeling might be a useful policy tool for preventing kidney function decline, adding to the potential health benefits of this front-of-pack labelling system.

High consumption of ultra-processed food may double the risk of subclinical coronary atherosclerosis: the Aragon Workers' Health Study (AWHS).

BACKGROUND: Ultra-processed food (UPF) consumption, which is increasing worldwide, has recently been associated with an increased risk of death and cardiovascular disease. We aimed to assess whether consumption of UPF is directly associated with subclinical coronary atherosclerosis in middle-aged men. METHODS: A computed tomography scan was performed on 1876 men from the Aragon Workers' Health Study, recruited from January 2011 to December 2014, to assess coronary calcium. All participants were free of coronary heart disease. Dietary intake was collected by a validated 136-item semi-quantitative food frequency questionnaire. UPF was defined according to the NOVA classification. Associations between consumption of total energy-adjusted UPF and Coronary Calcium Agatston Score (CACS)-categorized into CACS of 0, > 0 and < 100, and ≥ 100-were cross-sectionally assessed by generalized ordered logistic regression adjusted for main confounders. RESULTS: No coronary calcium was detected in 60.2% of the participants, whereas 10.2% had a CACS ≥ 100. A significant dose-response association was observed between energy-adjusted UPF consumption and the risk of having a CACS ≥ 100, when compared with those in the lowest CACS categories (CACS of 0 together with CACS > 0 and < 100). The fully adjusted ORs (95% CI) of having a CACS ≥ 100 across quartiles of energy-adjusted UPF consumption (approximately 100 g/day in the lowest quartile (ref.) and 500 g/day in the highest) were 1.00 (ref.), 1.50 (0.93, 2.42), 1.56 (0.96, 2.52), and 2.00 (1.26, 3.16), p trend .005. CONCLUSION: In this middle-aged worker's sample, approximately 500 g/day of UPF consumption was associated with a 2-fold greater prevalence of subclinical coronary atherosclerosis than consuming only 100 g/day, independently of total energy intake and other well-established cardiovascular risk factors.
