Lecithin

Lecithin is a natural fat-like substance found in many plants and animal tissues, especially in eggs, soybeans, and sunflower seeds. It acts as an emulsifier, helping fats mix evenly with water, which is important in cooking and food manufacturing. In the body, lecithin is a key component of cell membranes, supporting healthy cell structure and function. It also supplies choline, a nutrient vital for brain health and nerve signaling. Commonly used as a supplement or food additive, lecithin can improve texture and extend shelf life in processed foods.
