Such an effect is not commonly seen as even the most healthy oils have a strong lowering effect on cholesterol but only mild effect on triglycerides. In the study, walnut oil, given in capsule form 3 gm per day for 45 days. The blood triglycerides (TG) decreased by as much as 33% , which is tremendous improvement.
One can make use of this fact and use walnut oil in dishes without heating it. When walnut oil is heated, it loses much of its nutritional value and antioxidant power when heated.
