Here's the actual study:
Association Between Consumption of Ultraprocessed Foods and Cognitive DeclinePublished online December 5, 2022"In the last 40 years, the food supply industries have increased the commercialization of ultraprocessed foods (UPFs).13 Such UPFs are formulations of processed food substances (oils, fats, sugars, starch, and protein isolates) that contain little or no whole foods and typically include flavorings, colorings, emulsifiers, and other cosmetic additives.14
Examples of UPFs are sweet and savory snacks, confectionery, breakfast cereals, ice cream, sugar-sweetened beverages, processed meats, and ready-to-eat frozen meals. Fifty-eight percent of the calories consumed by US citizens, 57% of the calories consumed by British citizens, and 48% of the calories consumed by Canadian citizens come from UPFs.15-17 In Brazil, this group of foods contributes to 30% of total calorie intake.18 Consumption of UPFs has been linked to an increased risk of cardiovascular disease, metabolic syndrome, and obesity.19,20 However, few studies have investigated the association between UPF and cognitive decline in samples from high-income countries.21-23 Therefore, we aimed to prospectively investigate the association between UPF consumption at baseline and cognitive decline in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).
In this large cohort study, a higher percentage of daily energy from UPF was associated with cognitive decline during 8 years of follow-up. Intact cognitive function is key to successful aging. Therefore, despite the small effect size of the association between UPF consumption and cognitive decline, our findings are meaningful to cognitive health. Limiting UPF consumption, particularly in middle-aged adults, may be an efficient form to prevent cognitive decline."
