Adherence to a Mediterranean dietary pattern (defined by at least two components such as high monounsaturated/saturated fat ratio, high fruit/vegetable intake, etc.) produces small but statistically significant reductions in total cholesterol and LDL cholesterol in adults, though it does not significantly reduce clinical cardiovascular events in primary prevention settings based on current trial data.
Adopting a Mediterranean-style diet, defined by incorporating at least two key components like using olive oil as your main fat and eating plenty of fruits and vegetables, leads to small but measurable improvements in cholesterol levels (specifically total and LDL cholesterol). While this pattern may not directly prevent heart attacks or strokes in the short term based on current trials, it effectively modifies key cardiovascular risk factors. Focus on these two core changes rather than trying to replicate every aspect of the traditional diet perfectly.
Small reductions in total cholesterol (-0.16 mmol/L... ) and low-density lipoprotein (LDL) cholesterol (-0.07 mmol/L... ) were seen with the intervention... Clinical events were reported in only one trial... where no statistically significant effects of the intervention were seen on fatal and non-fatal endpoints at eight years.
Why this rating
Based on 11 RCTs with 52,044 participants, but significant heterogeneity in intervention definitions and lack of clinical event data in most trials limits certainty.

- 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
