護理師教導病人維生素與礦物質需求，下列哪些食物富含鈣質？（選所有適合的）
A nurse is teaching a client about vitamin and mineral needs. Which source is rich in calcium? (Select all that apply.)
- AYogurt✓ 正解優格
- BSpinach✓ 正解菠菜
- CFortified almond milk✓ 正解強化杏仁奶
- DWhite bread白麵包
- ESardines (with bones)✓ 正解沙丁魚（帶骨）
鈣質是維持骨骼健康與肌肉收縮的重要礦物質。在臨床飲食衛教中，護理師應引導病人攝取高生物利用率的鈣質來源。優格、強化植物奶及帶骨沙丁魚皆為極佳來源。菠菜雖含有鈣質，但因含有草酸（oxalate），會與鈣結合影響吸收率，不過在廣義分類中仍被視為含鈣食物。白麵包屬於精緻碳水化合物，鈣含量極低，不適合作為鈣質主要攝取來源。
Calcium is an important mineral for maintaining bone health and muscle contraction. In clinical dietary teaching, the nurse should guide clients to consume calcium sources with high bioavailability. Yogurt, fortified plant milks, and sardines with bones are all excellent sources. Spinach contains calcium, but its oxalate content binds with calcium and reduces absorption; nevertheless, it is still classified broadly as a calcium-containing food. White bread is a refined carbohydrate with very little calcium and is not appropriate as a primary source of dietary calcium.
