file this under the obvious for must of here but a shocker for the mainstream. high saturated fat creates the cholesterol building blocks for a healthy brain
"Consumption of ≥50 g/d of high-fat cheese (>20% fat) was associated with a reduced risk of all-cause dementia (HR 0.87; 95% CI, 0.78–0.97) and VaD (HR 0.71, 95% CI 0.52–0.96) compared with lower intake (<15 g/d). An inverse association between high-fat cheese and AD was found among APOE ε4 noncarriers (HR 0.87, 95% CI 0.76–0.99, p-interaction = 0.014). Compared with no consumption, individuals consuming ≥20 g/d of high-fat cream (>30% fat) had a 16% lower risk of all-cause dementia (HR 0.84, 95% CI 0.72–0.98). High-fat cream consumption was inversely associated with the risk of AD and VaD. "
