E526, or calcium hydroxide, is a food additive widely used in the food industry as a stabilizer, acidity regulator, and antioxidant.
Calcium hydroxide can be found in various products such as canned goods, juices, dairy products, and some types of bakery products. It can also be used in keto desserts, for example, in carb-free puddings or jams.
Calcium hydroxide does not contain carbohydrates and does not directly affect blood glucose levels. However, excess calcium can lead to the formation of kidney stones, so it is important not to consume it in excess.
Overall, calcium hydroxide can be considered a relatively safe additive if consumed in moderate amounts.
