Which has less cholesterol, mustardoil or sunflower oil?

It's a toss-up: Mustard oil has no cholesterol but is 100% fat, 14% of which is saturated fat, 59% monounsaturated. Sunflower oil also has no cholesterol and is 100% fat but 11% is saturated, 57% monounsat. Both have the same number of calories (120 per 15 gram serving). Monounsat fats are good when substituted for the small amt of fat included in a healthy diet.

LDL, not Cholesterol: Cholesterol is a fat molecule manufactured by every animal cell, a building block of each cell membrane (enables membrane fluidity/movement without tearing), is fundamental to the survival of every animal cell. Lipoproteins (proteins which transport all fats in the water outside cells) is the correct issue for artery disease (e.g. Ldl ≤700 nmol/l, HDL ≥45 µmol/l). Cholesterol ↓$, but misleading.
