I. Incompatible Foods

1. Spinach: Both are high-oxalate vegetables; consuming them together in large quantities may increase the risk of calcium oxalate crystallization, triggering symptoms of kidney or urinary stones.

2. Dairy Products: Calcium ions in milk combine with oxalic acid in shepherd's purse to form insoluble precipitates; long-term co-consumption may reduce calcium absorption efficiency.

3. Seafood: Seafood is rich in purines, and oxalic acid in shepherd's purse may inhibit uric acid excretion; co-consumption by gout patients can easily induce joint inflammation.

4. Persimmons: Unripe persimmons contain large amounts of tannic acid; when consumed with shepherd's purse, this may cause gastric bezoar formation and abdominal distension.

5. Strong Tea: Caffeine in tea combines with polyphenols in shepherd's purse, potentially affecting intestinal iron absorption and worsening anemia tendencies.

II. Compatible Foods

1. Citrus Fruits: Vitamin C in citrus fruits can reduce ferric iron in shepherd's purse to ferrous iron, increasing non-heme iron absorption rates by 2-3 times.

2. Tofu: Soy isoflavones work synergistically with shepherd's purse saponins to enhance bone metabolism, making it suitable for menopausal women.

3. Brown Rice: Its B-vitamin complex can break down oxalic acid in shepherd's purse, reducing its antagonistic effects on minerals and improving overall nutrient absorption.

4. Bananas: Potassium can neutralize electrolyte imbalances caused by oxalic acid in shepherd's purse, alleviating muscle cramps, particularly suitable for post-exercise recovery.

5. Eggs: High-quality protein complements dietary fiber in shepherd's purse, enhancing satiety while maintaining stable blood glucose levels.
