While vegetable oil has been shown to lower cholesterol, it may not help extend your lifespan. Most advice in recent years has been to reduce saturated fat intake and replace it with unsaturated fats like vegetable oils in order to boost heart health. “The new report, which analyzed 40-year-old data from the Minnesota Coronary Experiment, found no association between lower cholesterol levels and longer life, suggesting that reducing the amount of saturated fat in the diet isn’t enough to reduce risk of death from heart disease. While the diet rich in vegetable oil did lower cholesterol levels over the 4-5 year study period, compared to a control group (who continued to eat saturated fat daily), the researchers found no change in the rate of death from heart-related ailments.”  Even though this particular study did not indicate that cholesterol and longevity are linked, “many studies show the benefit of statin medications to lower blood cholesterol, that are highly associated with a reduced risk of death.”
