E442, also known as ammonium phosphatides, is an additive that is typically produced from phosphatidylcholine. This, in turn, can be derived from soy.
This means that when using products with E442, it is important to consider its source, especially if you are following a keto diet and prefer to avoid soy.
From a keto diet perspective, E442 itself contains no carbohydrates and should not significantly affect blood sugar levels.
E442 is commonly used in dairy products, pies, ice cream, cream candies, and other confectionery items.
