Despite the commonly held impression that fats are bad for you, fat isn’t always the villain in our diets. Some fats, such as trans fats and saturated fats, do indeed contribute to weight gain and clogged arteries. However, good fats such as monounsaturated and polyunsaturated fats have the opposite effect. They are in fact helping to build a strong and resilient mind and body, fight fatigue and even control weight. The key issue is not cutting out all fat, it is instead learning to make healthy choices by replacing bad fats with good ones. The information in Comparison of Dietary Fats provides and excellent explanation and visual comparison of the fats in edible oils.
