Which of the following is NOT a source of fats?

Fruits are primarily composed of carbohydrates, particularly natural sugars, and are a significant source of vitamins, minerals, and fiber. While some fruits may contain small amounts of fat, they are not considered a significant source of fats in the diet. For example, avocados and olives are exceptions where fruit contains higher fat content, but the majority of fruits, such as apples, oranges, and berries, do not.

In contrast, vegetable oils, nuts, and egg yolks are well-established sources of fats. Vegetable oils are predominantly made up of fatty acids, nuts are rich in healthy fats including monounsaturated and polyunsaturated fats, and egg yolks contain both fat and cholesterol. Each of these options contributes significantly to fat intake in diets, highlighting that they are true sources of dietary fats, while fruits as a whole do not fulfill this role to the same extent.
