Final answer:
Many meals served at fast-food restaurants are high in sodium and fat, which contributes to their high caloric content. They are not very nutrient-dense and frequently consuming these meals can have negative health effects.
Step-by-step explanation:
The majority of meals offered at fast-food restaurants are best described as high in sodium and fat. These meals are notorious for being calorie-dense yet not very nutrient-rich. They typically contain large amounts of saturated fat, contributing to a high daily value (DV) of total fat intake. This high-fat content is the main reason for the high caloric value of these meals. Additionally, fast-food items often contain a significant amount of sodium, which can exceed the recommended dietary limits when consumed frequently.
