A recent large genetic study found that higher blood sugar levels after meals, not just fasting glucose, may increase the risk of Alzheimer's disease later in life. This suggests that repeated post-meal spikes could play a role in long-term brain aging.
Why does this matter? It shifts the focus from average blood sugar to how the body handles glucose challenges over time. Small daily choices that support steadier blood sugar may matter for more than metabolic health, they may matter for cognitive health, too.
