Which statement regarding dairy products and vitamin D content is true?

The statement regarding dairy products and vitamin D content that is accurate focuses on cup equivalents being based on vitamin D content. Dairy products are a significant source of vitamin D, which is essential for calcium absorption and bone health. The establishment of cup equivalents recognizes the role that vitamin D plays in overall nutrition.

This means that when determining how many servings of dairy a person should consume, the vitamin D content is considered, as it can influence dietary recommendations and dietary allowances. The goal is to ensure adequate intake of this critical nutrient, especially when it comes to assessing dietary needs for certain populations.

The other statements miss the mark as they do not accurately reflect how vitamin D is associated with dairy consumption. For example, the fat content can indeed affect the amount of vitamin D in a product, but it does not control the establishment of cup equivalents. Hence, not all dairy products have uniform vitamin D levels nor is vitamin D irrelevant in nutritional recommendations for dairy intake.
