Conventional LDL Cholesterol

The cholesterol-centered model is criticized as financially reinforced by the pharmaceutical industry. Conventional LDL cholesterol is a calculated indirect number, not a direct measurement of LDL particles, derived from the Friedewald equation developed in the 1950s and 1960s. Cholesterol was adopted as a crude gauge of lipoprotein number and behavior because researchers at the time could not directly quantify lipoproteins. The dietary interpretation linking high LDL to saturated fat intake is criticized as having steered people toward low-fat, high-carbohydrate eating patterns over the past 50 to 60 years. Cholesterol content does not directly describe particle count, particle size, surface characteristics, oxidation, glycation, inflammatory behavior, or clearance from the bloodstream. Lowering LDL cholesterol with statins is considered an inadequate strategy because LDL cholesterol is only a crude indirect marker that does not capture the full metabolic pattern.
