“…We conducted binary logistic regression analyses to examine the association of total coffee consumption, caffeinated coffee consumption, decaffeinated coffee consumption and caffeine intake from coffee with cognitive performance. Based on prior studies and theoretical considerations [40,49,50], we selected established risk factors for cognitive performance, which were also known to be associated with coffee intake. Model 1 did not adjust any confounders.…”

The aim of this study was to examine the association of coffee, caffeinated coffee, decaffeinated coffee and caffeine intake from coffee with cognitive performance in older adults. we used data from the National Health and Nutrition Examination Survey (NHANES) 2011–2014. Coffee and caffeine intake were obtained through two 24-hour dietary recalls. Cognitive performance was evaluated by the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) test, Animal Fluency test and Digit Symbol Substitution Test (DSST). Binary logistic regression and restricted cubic spline models were applied to evaluate the association of coffee and caffeine intake with cognitive performance. A total of 2513 participants aged 60 years or older were included. In the fully adjusted model, compared to those reporting no coffee consumption, those who reported 266.4–495 (g/day) had a multivariate adjusted odd ratio (OR) with 95% confidence interval (CI) of 0.56(0.35–0.89) for DSST test score, compared to those reporting no caffeinated coffee consumption, those who reported ≥384.8 (g/day) had a multivariate-adjusted OR (95% CI) of 0.68(0.48–0.97) for DSST test score, compared to the lowest quartile of caffeine intake from coffee, the multivariate adjusted OR (95% CI) of the quartile (Q) three was 0.62(0.38–0.98) for the CERAD test score. L-shaped associations were apparent for coffee, caffeinated coffee and caffeine from coffee with the DSST test score and CERAD test score. No significant association was observed between decaffeinated coffee and different dimensions of cognitive performance. Our study suggests that coffee, caffeinated coffee and caffeine from coffee were associated with cognitive performance, while decaffeinated coffee was not associated with cognitive performance.

“…Evidence related to cognitive function is lacking; however, cross-sectional [132] and prospective studies [133] indicate a positive association between protein intake and cognitive function. Therefore, future investigation is warranted to elucidate the potential association of energy intake with cognitive and physical function in patients with diabetes.…”

Nutrition Management in Older Adults with Diabetes: A Review on the Importance of Shifting Prevention Strategies from Metabolic Syndrome to Frailty

et al. 2020

The increasing prevalence of older adults with diabetes has become a major social burden. Diabetes, frailty, and cognitive dysfunction are closely related to the mechanisms of aging. Insulin resistance, arteriosclerosis, chronic inflammation, oxidative stress, and mitochondrial dysfunction may be common mechanisms shared by frailty and cognitive impairment. Hyperglycemia, hypoglycemia, obesity, vascular factors, physical inactivity, and malnutrition are important risk factors for cognitive impairment and frailty in older adults with diabetes. The impact of nutrients on health outcomes varies with age; thus, shifting diet therapy strategies from the treatment of obesity/metabolic syndrome to frailty prevention may be necessary in patients with diabetes who are over 75 years of age, have frailty or sarcopenia, and experience malnutrition. For the prevention of frailty, optimal energy intake, sufficient protein and vitamin intake, and healthy dietary patterns should be recommended. The treatment of diabetes after middle age should include the awareness of proper glycemic control aimed at extending healthy life expectancy with proper nutrition, exercise, and social connectivity. Nutritional therapy in combination with exercise, optimal glycemic and metabolic control, and social participation/support for frailty prevention can extend healthy life expectancy and maintain quality of life in older adults with diabetes mellitus.

“…However, cognitive performance is a highly fluid and complex measurement that is affected by physical, mental, and emotional aspects of one's life. The authors have incorporated several of the above covariates in their other studies using NHANES [5,8] and thus are available and should be included in future studies.…”

“…While the authors have appropriately controlled for demographic, socioeconomic, physical activity, and cardiometabolic comorbidity factors, there are several other covariates that need to be accounted for, including 1) vitamin and mineral consumption (as authors have mentioned, vitamin Bs [ 2 ], vitamin D [ 3 ], folate [ 4 ], among others, have all shown protective effects on cognitive function), 2) other dietary consumption (protein intake [ 5 ] has been shown to be protective whereas saturated fats and refined sugars [ 6 ] have been associated with cognitive decline), 3) source of fatty acid (plant-based vs. animal-based [ 7 ]), 4) mental health status (e.g. depression [ 8 ] using the nine-item Patient Health Questionnaire), 5) other non-cardiometabolic comorbidities such as liver disease, pre-diabetes, and gastrointestinal disorders [ 9 ] that alter the gut microbiome, 6) behavioral factors such as smoking status [ 10 ], 7) day-to-day activities (e.g.…”

Over the past decade, there have been many studies determining the effect of dietary ω-3 and ω-6 fatty acids intake on cognitive performance; however, they have largely been inconsistent in their conclusions. In this letter, we provide context to the article by Dong et al., titled “Association of dietary ω-3 and ω-6 fatty acids intake with cognitive performance in older adults: National Health and nutrition examination Survey (NHANES) 2011–2014” and provide methodological considerations with regards to covariate measurement and inclusion that can be generalized to future cross-sectional studies. In particular, delineating 1) the type and source of fatty acid, in context of an individual’s overall dietary patterns, 2) sociobehavioral risk factors and physical & mental comorbidities, 3) and daily cognitive activity are important to adequately control for covariates.
