Which one among the following is not a good source of nutritional calcium?

Result
Your answer: —  Â·  Correct: A
Explanation

Polished white rice is a very poor source of dietary calcium compared with the other options: studies and food analyses show polished white rice preparations contain only about 1–10 mg Ca/100 g, i.e. negligible amounts for meeting calcium needs [2]. In contrast, finger millet (ragi) is a well-recognized calcium-rich cereal (reported values ~364 mg/100 g for some varieties) and millets are promoted for their high mineral content [2]. Milk and low-fat/skimmed milk are established dietary sources of calcium and are recommended as calcium-rich foods in dietary guidance [3]. Eggs contain some calcium but not nearly as little as polished white rice; therefore rice is not a good source of nutritional calcium.
