Can adding olive oil or safflower oil to your diet lower your cholesterol level?

Absolutely: The substitution of unsaturated fats and oils in dietary management will contribute to better cholesterol profiles.

Perhaps: This will only be helpful if you use these healthy oils to replace unhealthy oils/fats in your diet.

Dieters Beware, Pt.3: FAT BLOCKERS (Guar gum, Hydroxycitrate, Chitosan) Claim: You won't absorb as much dietary fat from your food. Science: There isn't strong evidence that these work without a lower-calorie diet. Risks: Some cause diarrhea and inhibit vitamin absorption, while others made from shellfish may trigger allergic reactions. (Ref. Time,7/14)
