Some people also take them as supplements, and they can come in capsules, liquid, or granules.In the food industry, lecithin is used as an additive to combine foods, the medical center added. One example is salad dressing.Soy lecithin emulsifies ingredients, such as oil and water, to blend the salad dressing into a smooth consistency, Judy Simon, a clinical dietitian nutritionist at the University of Washington, previously told USA TODAY.
