Diet is part of the picture, not all of it
For most people the body makes the majority of its own uric acid. Food contributes the smaller share. Eating well lowers your risk and helps you feel in control, but for many people diet alone does not bring uric acid down enough to stop flares. Medication often does the heavy lifting. Use these grades to make easier daily choices, and work with your doctor on the full plan.
