Are Navy Beans High in Oxalates?

If you’re wondering “are navy beans high in oxalates,” here’s the short answer.

Navy Beans contains about 96mg of oxalates per 1/2 cup cooked (91g). That is considered very high compared to other foods. Navy beans have about 96mg of oxalates per half cup cooked. That nearly fills the entire 100mg daily budget from one serving.

To put that in perspective, most kidney stone dietitians recommend staying under 100mg of oxalates per day. A single serving of navy beans uses 96% of that budget.

How Does This Compare?

Among legumes, navy beans are one of the highest. Soybeans have 48mg, black beans 32mg, kidney beans just 10mg. Navy beans are a hidden oxalate trap.

Who Should Watch Their Intake?

Navy beans are common in baked beans, soups, and casseroles. People managing kidney stones should choose kidney beans, lentils, or chickpeas instead.

Lower-Oxalate Alternatives

  • Kidney beans (10mg/half cup)
  • Lentils (8mg/half cup)
  • Chickpeas (16mg/half cup)
  • Cannellini beans (moderate)

What Are Oxalates?

Oxalates (oxalic acid) are natural compounds found in many plants. Your body also produces them as a metabolic byproduct. In small amounts, they pass through your system without issues.

The problem starts when oxalate intake is high and calcium intake is low. Oxalates bind to calcium in the kidneys and form calcium oxalate crystals, the most common type of kidney stone. About 80% of kidney stones are calcium oxalate.

How to Reduce Oxalate Absorption

  • Pair high-oxalate foods with calcium. Eating calcium-rich foods (like cheese or yogurt) at the same meal binds oxalates in the gut before they reach the kidneys.
  • Cook your vegetables. Boiling reduces oxalate content by 30-50% because oxalates leach into the water. Steaming helps less.
  • Drink plenty of water. Staying hydrated dilutes oxalate concentration in urine, reducing crystal formation.
  • Spread intake across meals. A moderate-oxalate food at each meal is better than a high-oxalate food all at once.

The Bottom Line

Navy Beans is very high in oxalates. If you have a history of kidney stones or are on a low-oxalate diet, limit or avoid it. There are good alternatives that give you similar nutrition without the oxalate load.
