Pure soy. Supportive but not conclusive scientific evidence suggests that eating about 1-1/2 tablespoons (20.5 grams) daily of soybean oil, which contains unsaturated fat, may reduce the risk of coronary heart disease. To achieve this possible benefit, soybean oil is to replace saturated fat and does not increase the total number of calories you eat in a day. One serving of this product is 14 grams (15 mL) of soybean oil.
