A low sodium diet is crucial for you because excess sodium raises blood pressure and increases protein spillage in urine, both major concerns with IGAN. Aim for under 2,300mg sodium daily. Quick tips:

Fresh foods over processed
Read labels carefully
Use herbs/spices instead of salt
Cook at home more often
Watch for hidden sodium in:
Bread
Canned foods
Deli meats
Restaurant meals
Always discuss specific dietary changes with your healthcare team, as individual needs vary based on medications and other factors.
