potatoes (mashed, boiled, baked)
What this could lead to
If it works, this could show that eating potatoes instead of refined starches like white rice or pasta may improve sleep and blood sugar control.
What could go wrong
This is a small, completed trial with only 71 healthy adults, so results may not apply to everyone. Dietary studies are hard to control, and findings may not be conclusive.
