Which foods are good calcium sources?

• A. Dairy products and leafy greens
• B. Red meats and fish without bones
• C. Whole grains and corn syrup
• D. Oils and fats

Answer: (A)

Calcium in the diet comes from foods that provide substantial amounts in a form the body can use. Dairy products—milk, yogurt, and cheese—supply calcium in a highly bioavailable form, aided by lactose and certain proteins that help absorption. Leafy greens such as kale and collard greens also contribute calcium, though absorption varies by type; some greens (like spinach) have calcium that the body can’t absorb as well due to oxalates, while others are excellent sources. In contrast, red meats and fish without bones contain little calcium; whole grains and corn syrup may contain some calcium but not in meaningful amounts and can include compounds that reduce absorption; oils and fats do not provide calcium. So pairing dairy products with leafy greens aligns with typical, well-absorbed calcium sources.
