What is lactose?
Lactose is a natural sugar found in milk and dairy products, which is formed after joining two sugars - glucose and galactose (yes, that's what it's called).
In order for our body to process it in time, it uses a natural enzyme - lactase, which splits lactose into the two sugars already mentioned. When not enough of the enzyme is produced, the human body may no longer be able to break down or fully absorb lactose, which then leads to symptoms.
Sometimes the level of this enzyme is low and the body still manages to digest dairy products. But when the level drops too much after consuming dairy products, various symptoms begin - abdominal pain, bloating, diarrhea.
Often this condition can be managed without giving up dairy products. But when that doesn't work, then you'll need lactose-free foods - lactose-free milk, cheese, etc. Add to your diet.
Lactose intolerance is different from milk allergy and the two should not be confused. We have already mentioned that intolerance to this sugar occurs due to lack of enzyme, and allergy is a reaction to milk protein.
