Mediterranean #diet adherence and rate of cerebral Aβ- #amyloid accumulation: Data from the Australian Imaging, Biomarkers and Lifestyle Study of Ageing
https://www.nature.com/articles/s41398-018-0293-5
The relationship between MeDi adherence, MeDi components, and change in cerebral Aβ load (baseline to 36 months) was evaluated using Generalised Linear Modelling, accounting for age, gender, education, Apolipoprotein E ε4 allele status, body mass index and total energy intake. Higher MeDi score was associated with less Aβ accumulation in our cohort (β = −0.01 ± 0.004, p = 0.0070). Of the individual MeDi score components, a high intake of fruit was associated with less accumulation of Aβ (β = −0.04 ± 0.01, p = 0.00036).
Our results suggest MeDi adherence is associated with reduced cerebral AD pathology accumulation over time. When our results are considered collectively with previous data linking the MeDi to slower cognitive decline, it is apparent that MeDi adherence warrants further investigation in the quest to delay AD onset.

Association of Midlife #Diet With Subsequent Risk for #Dementia
https://jamanetwork.com/journals/jama/article-abstract/2727449
Alternate Healthy Eating Index (AHEI)
Observational studies suggest that diet is linked to cognitive health. However, the duration of follow-up in many studies is not sufficient to take into account the long preclinical phase of dementia, and the evidence from interventional studies is not conclusive.
Compared with the worst AHEI tertile in 1997-1999 (incidence rate for dementia, 2.06 [95% CI, 1.62 to 2.61] per 1000 person-years), the absolute rate difference for the intermediate AHEI tertile was 0.14 (95% CI, −0.58 to 0.86) per 1000 person-years and for the best AHEI tertile was 0.14 (95% CI, −0.58 to 0.85) per 1000 person-years. Compared with the worst AHEI tertile in 2002-2004 (incidence rate for dementia, 3.12 [95% CI, 2.49 to 3.92] per 1000 person-years), the absolute rate difference for the intermediate AHEI tertile was −0.61 (95% CI, −1.56 to 0.33) per 1000 person-years and for the best AHEI tertile was −0.73 (95% CI, −1.67 to 0.22) per 1000 person-years. In the multivariable analysis, the adjusted hazard ratios (HRs) for dementia per 1-SD (10-point) AHEI increment were not significant as assessed in 1991-1993 (adjusted HR, 0.97 [95% CI, 0.87 to 1.08]), in 1997-1999 (adjusted HR, 0.97 [95% CI, 0.83 to 1.12]), or in 2002-2004 (adjusted HR, 0.87 [95% CI, 0.75 to 1.00]).
Conclusions and Relevance In this long-term prospective cohort study, diet quality assessed during midlife was not significantly associated with subsequent risk for dementia.

Population Impact Attributable to Modifiable Risk Factors for #Hyperuricemia
#BMI, #alcohol intake, adherence to a DASH‐style #diet, and diuretic use were all associated with serum urate levels and the presence of hyperuricemia in a dose‐response manner. The corresponding PARs of hyperuricemia cases for overweight/obesity (prevalence, 60%), non‐adherence to a DASH‐style diet (prevalence, 82%), alcohol use (prevalence, 48%), and diuretic use (prevalence, 8%) were 44% (95% CI, 41 to 48%), 9% (3% to 16%), 8% (5% to 11%), and 12% (11% to 14%), respectively, whereas the corresponding variances explained were 8.9%, 0.1%, 0.5%, and 5.0%. Our simulation study showed the variance nearing zero with exposure prevalence's nearing 100%.
Conclusion
In these nationally representative US adults, four modifiable risk factors (BMI, the DASH diet, alcohol use, and diuretic use) could individually account for a notable proportion of hyperuricemia cases. However, the corresponding serum urate variance explained by these risk factors was very small and paradoxically masked their high prevalences, providing real‐life empirical evidence for its limitations in assessing common risk factors.

A brief #diet intervention can reduce symptoms of #depression in young adults – A randomised controlled trial
There is strong epidemiological evidence that poor diet is associated with depression. The reverse has also been shown, namely that eating a healthy diet rich in fruit, vegetables, fish and lean meat, is associated with reduced risk of depression
No such RCTs have been performed in young adults. Young adults with elevated levels of depression symptoms and who habitually consume a poor diet were randomly allocated to a brief 3-week diet intervention (Diet Group) or a habitual diet control group (Control Group).
..The Diet group had significantly lower self-reported depression symptoms than the Control Group on the CESD-R (p = 0.007, Cohen’s d = 0.65) and DASS-21 depression subscale (p = 0.002, Cohen’s d = 0.75) controlling for baseline scores on these scales. Reduced DASS-21 depression subscale scores were maintained on follow up phone call 3 months later (p = .009). These results are the first to show that young adults with elevated depression symptoms can engage in and adhere to a diet intervention, and that this can reduce symptoms of depression.
The findings provide justification for future research into the duration of these benefits, the impacts of varying diet composition, and their biological basis.
