About two months ago, grad student Azure Grant began wearing a glucose monitor every day.
These devices track glucose, also called blood sugar, which comes from food and which the body subsequently uses for fuel. Diabetics have trouble regulating their glucose levels, and thus must track them closely.
Here’s the catch: Grant doesn’t have diabetes. But she began to be more curious about glucose after working with a group of diabetic individuals. She wondered: how reliably can it be measured? How did it change over time? What factors affect it, and what might it have to say about human health?
