Macro partitioning
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.
Stop obsessing over the ratio of your vegetable oils to fish oils. Instead, ensure you are eating enough linoleic acid (5-8% of calories) and enough EPA/DHA (500-1000 mg/day). If you meet these absolute targets, the ratio will naturally fall into a healthy range (~6:1).
StrongQualifiesVERY_HIGH confidence
the absolute mass of essential fatty acids consumed, rather than their n-6/n-3 ratio, should be the first consideration when contemplating lifelong dietary habits affecting cardiovascular benefit from their intake.
Why this rating
This is a central thesis of the review, supported by extensive discussion of threshold effects and clinical outcomes.

More from this paper
- 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.Good
- 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
