Twelve-Week Daily Consumption Of Ad Hoc Fortified Milk With Omega-3, D, And Group B Vitamins Has A Positive Impact On Inflammaging Parameters: A Randomized Cross-Over Trial
NUTRIENTS(2020)
摘要
Background and Aim: A state of chronic, subclinical inflammation known as inflammaging is present in elderly people and represents a risk factor for all age-related diseases. Dietary supplementation with ad hoc fortified foods seems an appealing strategy to counteract inflammaging. The purpose of this study was to test the efficacy of elderly-tailored fortified milk on inflammaging and different health parameters. Methods: A double-blind randomized cross-over study was performed on forty-eight volunteers aged 63-80 years. The fortified milk was enriched with omega-3 polyunsaturated fatty acids (eicosapentaenoic acid, EPA; docosahexaenoic acid, DHA), vitamins (25-hydroxyvitamin D, E, C, B6, B9, B12), and trace elements (zinc, selenium). The two intervention periods lasted for 12 weeks, with a 16-week washout intermission. Results: Compared to placebo, the consumption of fortified milk increased the circulating levels of different micronutrients, including vitamins and the omega-3 index of erythrocyte membranes. Conversely, it reduced the amount of arachidonic acid, homocysteine, and omega-6/omega-3 ratio. Conclusion: Twelve-week daily consumption of ad hoc fortified milk has an overall positive impact on different health parameters related to inflammaging in the elderly.
