Saturated fats are from animal products. Be moderate with unsaturated fats, especially monounsaturated fats. Research has shown that monounsaturated fats are healthy and beneficial. Olive oil is the most well known. I use this as my oil of choice in recipes.
Monounsaturated fats can lower cholesterol and the bad fats and the incidence of heart disease.
The Mediterranean diet has been studied extensively and it has shown reduced incidence of coronary heart disease. We need to consider incorporating the strategies of this diet into our own diet. Consider using olive oil as your fat of choice. When using olive oil, it has more flavor than the others, so you will wind up using less of it. It is a multi-beneficial approach to incorporating fat into our diets.
