In a cohort study[1] of 37,689 participants from the U.S. Women’s Health Initiative — Dietary Modification Trial (WHI-DM), lactose was the only sugar out of six subtypes that was significantly associated with AD risk. This suggests that dairy intake may increase AD risk, but other studies have found the opposite[2] or no effect[3].
