📊 How Bread white Compares

Among grains & pasta, Bread white sits well below the category average of 14 mg. For context, 170 out of 201 grains & pasta (84%) are rated 🟢 Safe (under 25 mg oxalate/serving). The average grains & pasta in our database has 14 mg oxalate per serving — which means Bread white is 93% below the category norm. Within its specific category, Bread white ranks among the lower-oxalate options. This context matters because two 'Safe' foods can have very different oxalate levels — one might have 5 mg while another has 24 mg. Both are Safe, but the first gives you more dietary flexibility.

❓ Related Questions

Why does the safe threshold matter?

The 25 mg cutoff comes from clinical guidance for stone formers. Below it, a food's oxalate contribution is small enough not to move the needle for most patients. Harvard's 2024 lab data sits behind these figures — direct measurements, not estimates. Bread white comes in at 1 mg oxalate per 1 slice (Safe) in the measured database.

Can I eat this food every day?

For Safe foods (under 25 mg/serving), daily use is generally fine. Caution and Avoid foods work better as occasional items — rotate them with safer options so no single high-oxalate food becomes a habit. For context, Bread white measures 1 mg per 1 slice, rated Safe.

Where does the oxalate data come from?

Harvard T.H. Chan School of Public Health (2024) via the OHF database. These are direct laboratory measurements — the most reliable oxalate data available for food. Bread white comes in at 1 mg oxalate per 1 slice (Safe) in the measured database.

Should I also check sodium and calcium?

Definitely. Oxalate is only part of the story — high sodium raises calcium in urine, and dietary calcium (from food, not pills) binds oxalate in the gut. The food's main page lists both, so it's worth checking before you plan around it. For context, Bread white measures 1 mg per 1 slice, rated Safe.
