Low-Oxalate, High-Calcium Vegetables: Cooking Broccoli, Napa Cabbage, and Gai Lan

Recommended List (Calcium Content and Absorption per 100 Grams)

• Broccoli: About 47 mg calcium, high absorption, and notably high in vitamin C too.
• Gai lan (Chinese kale): About 150 mg calcium, a standout among dark leafy greens.
• Napa cabbage, bok choy: About 90 to 105 mg calcium, and among the easiest to find in everyday shopping.
• Kale: About 150 mg calcium, increasingly common in salads in recent years.
• Okra: About 80 mg calcium, plus rich in dietary fiber and mucilage.

Simple Home Cooking Ideas

• Garlic broccoli: Blanch, then stir-fry quickly to keep the crisp-tender bite.
• Blanched gai lan: Quick and simple — finish with a touch of vegetarian oyster sauce substitute or soy sauce.
• Napa cabbage and tofu soup: Calcium from two sources at once, a good one to make often in autumn and winter.
• Kale salad: Massaging the raw leaves by hand briefly before eating softens them up.
• Dressed okra: Blanch, then top with crushed garlic and a drizzle of sesame oil for a refreshing side.

One Thing to Keep in Mind

These vegetables are low in oxalate with relatively good calcium absorption, but that doesn't mean you need to avoid high-oxalate vegetables like spinach entirely. A varied diet is the real foundation of balanced nutrition, and high-oxalate vegetables can still be eaten in moderation after blanching. Treat this list as a go-to reference for everyday meal planning rather than a strict rule.
