Final answer:
A 53-year-old woman should consume approximately three servings of milk to meet her RDA for calcium, assuming each serving provides around 300 mg of calcium.
Step-by-step explanation:
A 53-year-old woman needs to meet the Recommended Dietary Allowance (RDA) for calcium, which is 800 mg/day after 18 years of age. Milk is an excellent source of calcium, providing approximately 300 mg of calcium per 8-ounce (about 237 ml) serving. Based on this information, to meet her RDA of calcium, a woman would need to consume approximately three servings of milk, as this would provide about 900 mg of calcium, slightly over the RDA. Therefore, the correct answer to the question 'Approximately how many servings of milk would a woman of 53 years of age need to consume to meet her RDA for calcium?' is B. 3.
