Maldigestion du lactose : formes cliniques et solutions thérapeutiques

The lactose of dairy products is digested in the small intestine thanks to a membrane enzyme named lactase. For a large part of the world adult population, there is a decline in lactase activity and this leads to a partial malabsorption of the ingested lactose. In order to continue to consume dairy products and to avoid deficiency in calcium and vitamin D, several solutions can be considered. This is the case of yogurt that contains bacteria which have proven effective in lactose digestion. There are also processing aids that allow lactose hydrolysation or lactose remove from food products. Finally, dietary supplements can have a positive effect on lactose digestion if they are consumed at the same time of food products that contain lactose. All of these solutions are therefore intended to maintain the consumption of dairy products in people with lactose maldigestion.
