How did we get to this value? Well, we already know that milk contains lactose which is a sugar naturally occurring in this food and which is part of the carbohydrates family. Thus, 1 liter of milk contains 48 g of sugars, primarily lactose. Therefore, a glass of milk contains between 12 g and 15 g of carbohydrates (lactose), i.e. the equivalent of around 3 sugar cubes.
Moreover, let’s recall that milk is an excellent source of calcium and its consumption together with other dairy products plays an essential role in the health of the bones and teeth. Milk also constitutes a source of protein, of fat (in variable quantity based on it being skimmed, semi-skimmed or full-fat) and a multitude of vitamins and minerals.
Given its health benefits, it is advisable therefore to include milk, like other various dairy products, in our daily food plan unless otherwise advised by our doctor. And such a lactose intake should not prevent us from consuming it (except if suffering from lactose intolerance or from an allergy to cow milk proteins or other illnesses or health problems).
Finally, we should note that this information is useful for taking into consideration the quantity of sugar contained in milk so that we succeed in meeting our needs in sugars or in calculating our consumption of carbohydrates.
