Macro partitioning
High intake of saturated fatty acids from modern diets is linked to endotoxemia and inflammation, whereas unsaturated fatty acids do not produce this response.
Be aware that high-fat meals, particularly those high in saturated fat, can trigger an inflammatory response (endotoxemia). Choosing unsaturated fats helps avoid this inflammatory spike.
GoodSupportsHIGH confidence
Repeated experiments, with different designs and food products, have linked high SFA intakes with endotoxemia and inflammation... A single high-SFA meal elicits a response, with significantly elevated endotoxin levels. UFAs (particularly PUFAs) do not produce the same result
Why this rating
Supported by multiple experiments with different designs, though the paper notes the consistency of the pattern without detailing specific study limitations in depth.
