Blood lipid profile
Research suggests dairy fat raises LDL cholesterol relative to unsaturated plant oils in controlled feeding trials. That is a statement of direction rather than a benefit, and it is one of the better-replicated findings in diet and lipid research.
What may be going on: Saturated fatty acids, particularly palmitic and myristic acid, reduce hepatic LDL receptor activity and slow LDL clearance from the blood.
Moderate evidence. Several human studies point the same way, with real caveats.
