A nurse is teaching a patient at high risk for osteoporosis about dietary measures they can take to increase their calcium level.
Which of the following foods should the nurse advise the patient to increase in their diet?

Choice A rationale

Cabbage contains some calcium, but its bioavailability is lower compared to other sources due to the presence of oxalates, which can bind to calcium and inhibit its absorption in the small intestine. While vegetables are important for overall health, cabbage is not a primary food source recommended for significantly increasing calcium levels.

Choice B rationale

Carrots are a good source of beta-carotene and fiber but are not particularly high in calcium content. Their primary nutritional benefits lie in providing vitamin A precursors and supporting digestive health. Therefore, increasing carrot intake would not significantly impact calcium levels.

Choice C rationale

Potatoes contain minimal amounts of calcium. They are primarily a source of carbohydrates, potassium, and vitamin C. While part of a balanced diet, they are not a recommended food for specifically increasing calcium intake to prevent or manage osteoporosis.

Choice D rationale

Broccoli is a good source of non-dairy calcium, and its bioavailability is relatively high. Additionally, broccoli provides other essential nutrients like vitamin K, which plays a role in bone health. Increasing the consumption of cruciferous vegetables like broccoli can contribute to improved calcium intake and support bone density.
