Final answer:
The best source of dietary calcium is milk, yogurt, and ice milk, which are part of the milk/yogurt/cheese group. These items are rich in calcium, essential for bone strength and overall health, and are best consumed in low-fat or nonfat options for the same benefits with fewer calories.
Step-by-step explanation:
Best Sources of Dietary Calcium
The group of food items that provides the best source of calcium in the diet is a) Milk, yogurt, and ice milk. These items belong to the milk/yogurt/cheese group, which is recommended to be consumed two to three times daily to ensure adequate intake of calcium. This nutrient is essential for bone strength and plays a vital role in other bodily functions like neutralizing acidity in the digestive tract, and nerve and cell membrane functions.
While dairy products such as milk, yogurt, and cheese are recognized for being rich in calcium, it is also important to note that there are non-dairy sources. For those looking for alternative sources of calcium, green leafy vegetables, broccoli, nuts like almonds, beans, seeds, and fortified foods and beverages also contribute to the body's calcium needs. Nonetheless, dairy products typically contain higher levels of calcium which are readily absorbed by the body.
Individuals who prefer low-fat or nonfat dairy options can still receive the same amount of calcium as found in whole-milk products but with less fat and calories. For example, a single cup of low-fat milk provides about 300 mg of calcium, contributing substantially towards the recommended daily intake. To further prevent conditions such as osteoporosis, it's also advised to pair calcium-rich foods with vitamin D and engage in weight-bearing exercises.
