fedtbelastning

Fedtbelastning refers to the body's exposure to dietary fat, including the amount of fat consumed and the metabolic handling of fat after ingestion. In nutrition science it captures both external load (grams or percentage of energy from fat) and the internal physiological response, notably postprandial lipemia, the rise in blood triglycerides after a fat-containing meal.

Assessment combines dietary assessment to estimate fat intake with laboratory measures of fat metabolism. Fasting lipid panels and postprandial triglyceride tests after a standardized meal are used, and in research settings imaging can assess ectopic fat such as fatty liver.

Health implications: a high fettbelastning—especially when dominated by saturated or trans fats—has been linked to increased risk of cardiovascular disease, insulin resistance, and non-alcoholic fatty liver disease. The pattern of fat intake and clearance matters for risk.

Reduction and management include replacing saturated and trans fats with unsaturated fats, increasing fiber, and maintaining physical activity to improve fat clearance and reduce body fat.

Notes: fettbelastning is a conceptual measure that combines intake with metabolic response; individual differences in genetics, age, and health status influence it, and no single universal metric applies in all circumstances.
