The Two Types of Fat
Fat is a concentrated source of energy. / It can be divided into two main groups—saturated and unsaturated. / Saturated fat is generally solid at room temperature and is usually from animal sources. / It’s found in butter, hard margarine, cheese, whole milk and anything that contains these ingredients, / such as cakes, chocolate, biscuits, pies and pastries. / It’s also the white fat you can see on red meat and underneath poultry skin. / Unsaturated fat is usually liquid at room temperature / and generally comes from vegetable sources. / Unsaturated vegetable oils are generally a healthier alternative to saturated fat / and can be found in sesame, sunflower, soya, olive oil, soft margarine / and in foods such as oily fish, including sardines and salmon. /
The value of saturated and unsaturated fat in our diets isn’t fully understood yet, / but generally, eating too much saturated fat / is associated with an increased risk of heart disease. / Where possible, you should ensure that the fat you eat is unsaturated. /
