Practical tips

Read the daily-limit percentages rather than raw numbers — a food at 18% of the potassium limit is different from one at 8%. Check the full food page before adding something new to the routine — it shows all three minerals plus purine and oxalate where available.

Frequently asked questions

How much phosphorus can a CKD patient have per day?

For the rating basis used on this site, the daily limit is 1,000 mg of phosphorus at CKD stage 3-4. Individual targets depend on your labs and should be confirmed with your healthcare team.

What foods should I avoid on a stage 4 plan?

The caution list on this page shows the highest-load foods in the database. The top item on the caution list is Rice bran, crude at 1677 mg of phosphorus per 100 g — 168% of the daily limit. Each food page shows the exact percentage of the daily limit for all three minerals.

Are these recommendations right for everyone on a stage 4 plan?

No list can replace individual advice. This page covers 20 lower-risk foods and 12 caution items, rated per 100 g against the 1,000 mg phosphorus limit — your stage, blood results and medications all matter, so treat this as data, not a prescription.
