Diet sodas and artificially sweetened soft drinks linked to brain damage

Diet drinks TRIPLE your risk of stroke and dementia – and are FAR more dangerous than drinks sweetened with sugar

Two new studies from the same research group have found that those who consume one or more sugary drinks per day showed more brain shrinkage on MRI scans and performed more poorly on memory tests.

The researchers also said these diet drink consumers were twice as likely to have Alzheimer’s dementia.

2017 Study Abstract

Background and Purpose
Sugar- and artificially-sweetened beverage intake have been linked to cardiometabolic risk factors, which increase the risk of cerebrovascular disease and dementia. We examined whether sugar- or artificially sweetened beverage consumption was associated with the prospective risks of incident stroke or dementia in the community-based Framingham Heart Study Offspring cohort.

Methods
We studied 2888 participants aged >45 years for incident stroke (mean age 62 [SD, 9] years; 45% men) and 1484 participants aged >60 years for incident dementia (mean age 69 [SD, 6] years; 46% men). Beverage intake was quantified using a food-frequency questionnaire at cohort examinations 5 (1991–1995), 6 (1995–1998), and 7 (1998–2001). We quantified recent consumption at examination 7 and cumulative consumption by averaging across examinations. Surveillance for incident events commenced at examination 7 and continued for 10 years. We observed 97 cases of incident stroke (82 ischemic) and 81 cases of incident dementia (63 consistent with Alzheimer’s disease).

Results
After adjustments for age, sex, education (for analysis of dementia), caloric intake, diet quality, physical activity, and smoking, higher recent and higher cumulative intake of artificially sweetened soft drinks were associated with an increased risk of ischemic stroke, all-cause dementia, and Alzheimer’s disease dementia. When comparing daily cumulative intake to 0 per week (reference), the hazard ratios were 2.96 (95% confidence interval, 1.26–6.97) for ischemic stroke and 2.89 (95% confidence interval, 1.18–7.07) for Alzheimer’s disease. Sugar-sweetened beverages were not associated with stroke or dementia.

Conclusions
Artificially sweetened soft drink consumption was associated with a higher risk of stroke and dementia.

Sugary beverage intake and preclinical Alzheimer’s disease in the community, alzheimersanddementia, dx.doi.org/10.1016/j.jalz.2017.01.024, March 05, 2017.

Introduction
Excess sugar consumption has been linked with Alzheimer’s disease (AD) pathology in animal models.

Methods
We examined the cross-sectional association of sugary beverage consumption with neuropsychological (N = 4276) and magnetic resonance imaging (N = 3846) markers of preclinical Alzheimer’s disease and vascular brain injury (VBI) in the community-based Framingham Heart Study. Intake of sugary beverages was estimated using a food frequency questionnaire.

Results
Relative to consuming less than one sugary beverage per day, higher intake of sugary beverages was associated with lower total brain volume (1–2/day, β ± standard error [SE] = −0.55 ± 0.14 mean percent difference, P = .0002; >2/day, β ± SE = −0.68 ± 0.18, P < .0001), and poorer performance on tests of episodic memory (all P < .01). Daily fruit juice intake was associated with lower total brain volume, hippocampal volume, and poorer episodic memory (all P < .05). Sugary beverage intake was not associated with VBI in a consistent manner across outcomes.

Discussion
Higher intake of sugary beverages was associated cross-sectionally with markers of preclinical AD.
