Lactose is a natural sugar found in dairy products.
It contains a high amount of carbohydrates. Therefore, on a keto diet, it is often recommended to limit the consumption of dairy products rich in lactose and prefer options with lower lactose content, such as cottage cheese or hard cheeses, which contain fewer carbohydrates.
Lactose is broken down into glucose and galactose thanks to the enzyme lactase. Therefore, people with lactase deficiency may experience problems digesting lactose, leading to unpleasant symptoms such as bloating and diarrhea.
