Proteinuria: Good foods and bad foods

Proteinuria was detected in the school examination.

Even after retesting at the local hospital, proteinuria was detected.

I went to a large hospital and had another test.

Half-glucose test chin-up... check every 6 months

They say to receive it, whether you're tired or eating salty food.

Then I suppose that's possible... but it's been multiple times.

I only ate meat.

What kind of eating habits are necessary?
