Have you ever wondered why pre-grated cheese doesn’t stick together in the bag? It turns out that the secret ingredient behind this is an added substance called cellulose. …A natural substance found in plants and trees, cellulose is commonly used in the food industry as a food additive. Even though it is considered safe for consumption, many have still questioned its health implications and the safe amounts that should be consumed. …“Cellulose is generally recognised as safe by the FDA when used in food,” Ipsita Chakraborty, senior nutritionist at Hungry Koala remarks. It is a non-digestible plant fibre – which means it passes through the human digestive system without being broken down. It can aid in digestion by contributing to bulk in the diet.
