E506, or sodium hexametaphosphate, is an additive used in the food industry as a stabilizer, emulsifier, and acidity regulator.
Using E506 in products is not recommended on a keto diet for several reasons.
Firstly, sodium hexametaphosphate can disrupt the acid-base balance in the body, which can slow down the fat-burning process.
Additionally, E506 can cause allergic reactions in some individuals.
Products where E506 is most commonly found include carbonated beverages, various types of preserves, ice cream, and even some types of meat products.
