The Claim

In healthy adults, dietary saturated fat increases LDL cholesterol by 4.1% and monounsaturated fat decreases it by 5.2% over a 3-month period, indicating that the quality of dietary fat has a differential effect on LDL cholesterol, a key cardiovascular risk marker, even in metabolically healthy individuals.
