Most people focus on what they eat, but new research suggests that when you eat may be just as important—especially for brain health. A growing body of evidence links late-night eating and blood sugar spikes after meals to cognitive decline and even Alzheimer’s disease. In fact, one recent study found that people with elevated blood sugar after eating had a 69% higher risk of developing Alzheimer’s.
That statistic alone is enough to make anyone rethink their dinner routine. The concerning part is that this isn’t about rare behavior—it’s incredibly common, especially among busy adults and retirees who eat later in the evening. If your dinner habits include late meals or heavy nighttime eating, it may be time to take a closer look.
