Promise, Benecol, Becel and Smart Balance are some brands of margarine that contain plant sterols as of 2015. Plant sterols are alternatively known as phytosterols and stanols.
Promise Activ Light Spread is the Promise margarine product with plant sterols. A single tablespoon supplies omega fatty acids and less than 0.5 grams of saturated fat. Benecol regular and light spreads contain plant sterol esters derived from natural plant sources. A single tablespoon contains 0.5 grams of plant sterols. Benecol recommends cooking and baking with its light and regular spreads.
