Over 125,000 male and female health professionals free of CVD, cancer, and diabetes were followed for about 30 years. Saturated fat when replacing carbohydrates raised mortality rates by 8%. A high intake of trans fats was associated with a 13% increase in mortality. On the other hand, higher intakes of polyunsaturated fats (most vegetable oils) and monounsaturated fats (olive oil) reduced mortality rates 19% and 11%, respectively.
PositiveTip: Focus on reducing saturated and trans fats in your diet, while increasing polyunsaturated and monounsaturated choices.
