E425, also known as glycerol and glycerin, is an additive widely used in the food industry. Glycerin is often used in baking, confectionery, sweets, chewing gum, caramel, and other high-sugar products.
Glycerin has moisture-retaining properties and helps to preserve the texture and moisture of products.
It can be of vegetable or synthetic origin.
Although it usually does not cause a carbohydrate spike, some studies show that glycerin may increase blood sugar levels in some people.
Overall, moderate consumption of glycerin in products will not disrupt your keto diet, but it is important to remember that individual reactions to this additive may vary.
