Palm olein is a type of vegetable oil that is made from the liquid fraction of palm oil. It is commonly used as a cooking oil, as well as in a variety of food products, such as margarine and mayonnaise. Palm olein is high in saturated fats, which have been the subject of controversy in terms of their effect on health. Some studies suggest that palm olein may raise LDL (bad) cholesterol levels, while other studies have found that it may have health benefits, such as reducing the risk of heart disease. The American Heart Association recommends limiting intake of saturated fats, including palm olein, to no more than 6% of total daily calories. Palm olein has a relatively high smoke point, making it suitable for high-heat cooking methods such as frying and saut�©ing. It is also relatively inexpensive and widely available. Some people may be allergic to palm olein, so it is always a good idea to check with a doctor or allergist before using it.
