E517 is a food additive, also known as aluminum oxide.
It is widely used in the food industry as a stabilizer, anti-caking agent, and thickener.
From a keto diet perspective, the E517 additive is not an optimal choice due to its potentially negative impact on the body.
Aluminum oxide can cause irritation of the gastrointestinal tract in some individuals, leading to dysbiosis and other digestive issues.
Most commonly, the E517 additive is found in the production of baking, confectionery products, dry breakfast cereals, chewing gum, and other products where texture improvement and composition stabilization are required.
