Macro partitioning
Fish consumption, a source of n-3 polyunsaturated fatty acids, is associated with a reduced risk of incident dementia, particularly Alzheimer's disease.
Include fish in your diet regularly to potentially lower your risk of dementia, especially Alzheimer's disease. Even modest consumption levels were associated with significant benefits in this study.
GoodSupportsHIGH confidence
Fish consumption, an important source of n-3 polyunsaturated fatty acids, was inversely related to incident dementia (RR = 0.4 [0.2-0.9]), and in particular to Alzheimer's disease (RR = 0.3 [0.1-0.9]).
Why this rating
Prospective population-based cohort study with large sample size and rigorous case-finding protocol.

- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
