Which of the following is a major food contributor of fat in the American diet?

Hamburgers are considered a major food contributor of fat in the American diet primarily due to their composition. A typical hamburger contains a significant amount of ground meat, which often includes higher-fat cuts. This meat is then cooked, frequently with added fats such as oil or butter, and served on a bun that may also contribute additional fats through mayonnaise, cheese, or other condiments.

Moreover, hamburgers are a common fast-food item and are often consumed during meals that are higher in overall fat content, such as at barbecues or during dining out. In contrast, salads, fruits, and vegetables typically contain lower fat content, especially when served without high-fat dressings or toppings.

While salads can be dressed with fatty ingredients, that fat content is usually far less than what is found in a hamburger. Likewise, both fruits and vegetables are generally low in fat, making hamburgers a more substantial source of dietary fat in the American diet.
