Switching from saturated and trans fats to unsaturated fats (MUFAs and PUFAs) in the diet causally reduces plasma LDL particle concentration, thereby reducing the risk of atherosclerotic cardiovascular disease (ASCVD).
To lower your risk of heart disease, focus on swapping the types of fat you eat. Replace saturated fats (found in butter, fatty meats, full-fat dairy) and trans fats with unsaturated fats (found in olive oil, nuts, seeds, and fatty fish). This substitution lowers LDL cholesterol, which is a primary driver of heart disease. You don't need to eliminate fat; just choose higher-quality sources.
Importantly, the evidence suggests that dietary fat quality causally affects the risk of ASCVD via modulation of the plasma concentration of atherogenic apolipoprotein B (apoB)-containing lipoprotein particles.
Why this rating
Supported by genetic studies, Mendelian randomization, metabolic ward studies, and clinical trials showing consistent causal links.

- 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
