What is Lecithin?

Lecithin is a fatty substance that occurs naturally in plant and animal tissues and is commonly used in the food industry as an emulsifier to help blend ingredients that typically do not mix well, such as oil and water. It is often derived from sources such as soybeans, sunflower seeds, and eggs, but can also be extracted from corn, rapeseed, and animal tissues. Its versatility and ability to improve texture and extend shelf life make it a popular additive in a wide range of food products.

Why People Avoid Lecithin

People may avoid lecithin if they have allergies or sensitivities to its source ingredients, such as soy, eggs, or corn. Additionally, those following a corn-free diet need to be cautious because lecithin can sometimes be derived from corn. Without clear labeling, it can be difficult to determine the exact source of lecithin in a product, so contacting the manufacturer for confirmation is recommended for strict dietary adherence.
