Macro partitioning
Maintaining linoleic acid (LA) intake at 5-8% of energy is critical for cardiovascular health because it sets a threshold that mitigates the cholesterol-raising effects of saturated fats and cholesterol.
Aim to get 5-8% of your daily calories from linoleic acid (found in vegetable oils like soybean, corn, and sunflower oil). This amount acts as a buffer, preventing saturated fats and dietary cholesterol from raising your bad cholesterol (LDL) levels. Simply reducing total fat without ensuring adequate LA intake may not protect your heart.
If LA intake falls below the 'threshold' requirement... the hyperlipemic effects of other dietary stressors, including SFA, trans fatty acids, and cholesterol, will be greatly exaggerated.
Why this rating
Supported by multiple animal studies, meta-analyses, and epidemiological data, though the paper notes confounding in some human trials.

- The absolute mass of n-6 and n-3 fatty acids consumed is more important for cardiovascular health than the n-6/n-3 ratio.Strong
- Consuming 0.25-0.5% of energy as EPA and DHA (approx. 500-1000 mg/day) reduces cardiovascular disease risk, primarily by lowering triglycerides and acting as antiarrhythmic agents.Good

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- 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
