Each 100g provides 105mg of calcium (8% DV). Daily consumption contributes to your calcium pool, supporting bone density. However, the oxalates in leafy greens can bind some calcium, reducing absorption—so pair with vitamin D or dairy for better uptake.
With 252mg potassium (5% DV) and 65mg sodium (3% DV), the potassium-to-sodium ratio favors vasodilation. Potassium relaxes blood vessel walls and helps excrete excess sodium via urine, which can lower blood pressure over time.
At 55 calories per 100g and 95% water, pak-choi fills your stomach without energy surplus. The 1g fiber (4% DV) slows gastric emptying, prolonging fullness. This can aid weight management if it replaces higher-calorie sides.
The 0.8mg iron (4% DV) is non-heme, which is less absorbable. But the vitamin C in pak-choi (not listed, but typical) enhances conversion to absorbable ferrous iron. Daily consumption may help maintain iron stores, especially if paired with vitamin C-rich foods.
Verdict
Daily pak-choi is a low-calorie, nutrient-dense addition that supports bone and heart health. Just watch your total sodium intake and ensure you get enough calories and protein elsewhere.
⚠️ Who Should Avoid
- People on potassium-restricted diets (e.g., chronic kidney disease)
- Those taking blood thinners (vitamin K content may interfere)
