The name Becel originates from the three letter acronym BCL (Blood Cholesterol Lowering). When introduced, the blood cholesterol lowering effect was achieved by modifying the triacylglycerol (TAG) profile of the fat used in the margarine: an increased level of poly-unsaturated fatty acids (PUFA) reduces the blood cholesterol level. More recently, products were introduced under the "Pro-activ" sub-brand. These products are based on the effects of plant sterols and sterol esters on blood cholesterol lowering. In recent years the Becel/Flora brand has added cooking oil, pot yogurt and yogurt drinks to the non-margarine products, all of which are designed to help lower blood cholesterol level. This is achieved by a highly increased resorption of beta-sitosterol and other phytosterols which accumulate especially in the intima of blood vessels and may cause arteriosclerotic plaques. In consequence, consumption of Becel products does not lower the risk for coronary diseases such as arteriosclerosis and therefore does not inherit any medical benefits.
