Which of the following are common food sources of phosphorus?

Phosphorus is an essential mineral that plays a variety of roles in the body, particularly in bone formation, energy metabolism, and cell function. Each of the mentioned food sources contributes to the overall dietary intake of phosphorus.

Milk and chocolate are significant sources of phosphorus, primarily due to the high content found in dairy products. Dairy foods contribute to bone health because they provide not only phosphorus but also calcium.

Nuts and legumes are also rich in phosphorus. Foods like almonds, walnuts, and beans contain considerable amounts of this mineral, making them an important part of a balanced diet, particularly for individuals who may not consume animal products.

Whole grains are another common source of phosphorus. Whole grain products, such as brown rice and oats, contain phosphorus as part of their nutrient profile. Cola beverages often contain phosphoric acid, which is a source of phosphorus as well. Although the health effects of consuming cola should be considered, it is indeed a source of phosphorus.

Since all of these food sources provide phosphorus, the answer that encompasses all options as common sources is correct. Thus, the inclusion of diverse food sources helps ensure adequate phosphorus intake, which supports various bodily functions, especially in the elderly population where nutritional needs can vary substantially.
