What glucose has to do with your mood

How do glucose levels relate to depression and anxiety?

Depression is roughly twice as common in people with Type 2 diabetes, and anxiety diagnoses run about 20 percent higher too. That's not just the psychological weight of managing a diagnosis. A growing body of research points to a real biological connection between blood sugar dysregulation and mood. Insulin resistance appears to affect the brain's emotional regulation centers directly, and researchers have identified several possible mechanisms behind it. Here's what the science currently understands, and why it might be worth paying attention to glucose as part of supporting your mental health.

Five Key Takeaways

1. Diabetes roughly doubles the odds of depression.

People with Type 2 diabetes are about twice as likely to experience depression, and roughly 20 percent more likely to have an anxiety diagnosis.

2. Insulin resistance may affect the brain directly, not just indirectly.

Insulin receptors sit throughout the brain's emotional regulation centers, and impaired signaling there is linked to mood and stress-response changes.

3. High-sugar diets are tied to higher depression risk.

A study of nearly 70,000 women found that diets high in added sugar and blood-sugar-spiking foods were associated with increased odds of depression.
