Is Macadamia Milk Safe for Kidney Stones? (Safe)
mg oxalate
per serving
Serving: 1 cup (242 g)
Verdict: 🟢 Safe
Per 100g: 1 mg
Data: Harvard T.H. Chan SPH (2024)
The bottom line for Macadamia Milk: Safe (🟢), with 1 mg oxalate per serving — comfortably below the 25 mg safe cutoff. There's no need to limit it. Just keep your usual kidney stone basics in place: water throughout the day and calcium-rich foods at meals.
Putting Macadamia Milk in context: it lands well below the category average of 3 mg. In the database, 95% of dairy & eggs (87 of 91) fall in the 🟢 Safe group (under 25 mg oxalate/serving). The typical dairy & eggs here averages 3 mg oxalate per serving, so Macadamia Milk runs 70% below that baseline. That places it among the lower-oxalate options in its category. Why this matters: the gap between two Safe foods can be wide — one may hold 5 mg oxalate while another sits at 24 mg. The lower one leaves more room in your day.

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. Macadamia Milk comes in at 1 mg oxalate per 1 cup (Safe) in the measured database.
Can I eat this food every day?
Daily eating is fine for Safe foods (under 25 mg/serving). For Caution or Avoid foods, spread them out and alternate with low-oxalate picks. The idea is keeping your weekly oxalate load manageable, not eliminating any single food. Macadamia Milk comes in at 1 mg oxalate per 1 cup (Safe) in the measured database.
Where does the oxalate data come from?
Every oxalate figure is sourced from Harvard T.H. Chan SPH (2024), distributed via the OHF database. The values come from actual lab measurements of the foods — not from database averages or estimates. For Macadamia Milk, the measured oxalate value is 1 mg per 1 cup (Safe).
Should I also check sodium and calcium?
Yes — oxalate alone doesn't decide stone risk. Sodium pushes more calcium into urine, and calcium from food (not supplements) helps bind oxalate during digestion. The main food page covers sodium and calcium alongside oxalate. For Macadamia Milk, the measured oxalate value is 1 mg per 1 cup (Safe).
