High intake of total dietary fats, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA) is not significantly associated with the incidence risk of cardiovascular disease (CVD).
Current guidelines often recommend limiting total fat and saturated fat intake to prevent heart disease. However, this large, long-term study found no significant link between the amount of total fat, saturated fat, or unsaturated fats consumed and the risk of developing cardiovascular disease. This suggests that strictly limiting fat intake may not be necessary for CVD prevention, and attention might be better placed on the quality of fats and the overall dietary pattern.
Total fat, animal and plant sources of fats were not associated with risk of CVD events. No significant associations were found between total SFA, lauric acid, myristic acid, stearic acid, palmitic acid as well as MUFA and PUFA and CVD incidence.
Why this rating
Large prospective cohort study (n=2809) with long follow-up (median 10.6 years) and rigorous adjustment for confounders.

- 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
