Final answer:
The foods highest in phosphorus, as per the options given, are dairy products. Dairy along with meat and beans are particularly good sources, essential for bone strength and cellular functions.
Step-by-step explanation:
The foods highest in phosphorus are dairy products, cereals, egg yolk, meat, beans, and nuts. These sources are known to be rich in phosphorus. Considering the choices provided: fruits and vegetables, dairy products, lean meats, and grains and nuts, the correct answer would be dairy products, although lean meats and grains and nuts are also good sources.
Phosphorus is an essential mineral that plays a key role in bone strength, energy processing, pH regulation, and is a component of cell membrane phospholipids. Foods like milk and meat are noted as particularly good sources of phosphorus. On an average daily intake, an individual consumes about 800-1000 mg of phosphorus, which is typically double the intake of calcium.
