L'intolérance au lactose

Many adults consider themselves as “intolerant to milk and lactose”. Consequently they consume less dairy product and less calcium and are exposed to an increased risk of osteoporosis. This review considers the definition of lactose intolerance, its mechanisms and the dietetic management. Many subjects diagnose themselves erroneously as lactose intolerant as shown in randomised placebo controlled studies (especially for lactose doses below 7 g). Irritable bowel syndrome is a frequent explanation for this error in diagnosis. Maintaining lactose in diet is possible in the majority of cases when simple dietary advice are explained, understood and followed.
