Questions: Leanora is a 22-year-old college student who plays on her school's soccer team. Her coach invited a registered dietitian nutritionist to talk to the team about sports nutrition. The RDN recommended minimizing trans fatty acids from processed and packaged foods, but she explained that some trans fats do occur naturally. What foods have naturally occurring trans fatty acids? Multiple Choice Pastries, pies, and cookies None of the choices contain naturally occurring trans fatty acids. Beef, whole milk, and butter Nuts, seeds, and avocados

The answer is the third one (or C): Beef, whole milk, and butter.

Explanation for each option:

1. Pastries, pies, and cookies: These foods typically contain trans fatty acids that are artificially created through the process of hydrogenation, which is used to increase shelf life and stability of the fats in these products. They do not naturally contain trans fats.

2. None of the choices contain naturally occurring trans fatty acids: This statement is incorrect because there are foods that naturally contain trans fatty acids.

3. Beef, whole milk, and butter: These foods do contain naturally occurring trans fatty acids. Ruminant animals like cows produce trans fats in their stomachs through the action of bacteria, and these fats are then found in their meat and dairy products.

4. Nuts, seeds, and avocados: These foods are rich in healthy fats, such as monounsaturated and polyunsaturated fats, but they do not contain naturally occurring trans fatty acids.

Summary: Naturally occurring trans fatty acids are found in products derived from ruminant animals, such as beef, whole milk, and butter. These trans fats are different from the industrial trans fats found in processed foods like pastries, pies, and cookies.
