Which of the following foods has the highest number of grams of fat per 100 grams of food?

Vegetable oil contains a significantly high amount of fat, with nearly all of its caloric content coming from fats. In fact, most vegetable oils consist of about 100 grams of fat per 100 grams of oil, depending on the type of oil. This makes it one of the most concentrated sources of dietary fat available.

In contrast, chicken breast is a lean protein source, containing minimal fat, typically around 3-5 grams of fat per 100 grams. Avocado, while known for its healthy fats, provides about 15 grams of fat per 100 grams, mostly in the form of monounsaturated fats. Cheese varies widely in fat content depending on the type, but it usually contains fewer total grams of fat than vegetable oil, generally falling between 20 to 35 grams of fat per 100 grams.

Thus, when comparing these foods, vegetable oil clearly has the highest fat content per 100 grams, making it the correct answer.
