Answer:
- The Adequate Intake (AI) value for sodium for men and women ages 9-50 years: C. 1,500 mg
- The Tolerable Upper Intake Level (UL) for sodium per day: D. 2,300 mg
- The amount of sodium the Percent Daily Value (%DV) is based on: B. 2,400 mg
- The amount of sodium needed per day to maintain physiological function: A. 200 mg
Step-by-step explanation:
Sodium is a key dietary micronutrient that must be consumed daily in foods and beverages because the body is not able to generate sufficient quantities on its own. The World Health Organization (WHO) recommends a daily intake of 2 grams (2,000 mg) of sodium, whereas the American Heart Association (AHA) recommends 1,500 mg per day. Sodium is critical for regulating fluid levels in the body, muscle contraction, transmission of nerve impulses, and blood pressure. However, an excessive sodium intake can be harmful, because it holds extra fluid in the body, thereby creating an added burden on the heart and increasing blood pressure. In consequence, an excess of sodium in the diet may cause health problems such as heart diseases and stroke.
