Which of the following may contain trans fatty acids?

A.

Butter

B.

Olive oil

C.

Store bought cake

D.

Avocado pit

Answer and Explanation

The Correct Answer is C

A. Butter:

Butter contains saturated fats, but naturally occurring trans fats are minimal. Most concerns about trans fats focus on artificial trans fats, not the tiny amounts in butter.

B. Olive oil:

Olive oil is mostly monounsaturated fat and does not contain trans fats. It is considered a heart-healthy fat.

C. Store bought cake:

Processed baked goods like store-bought cake may contain artificial trans fats (partially hydrogenated oils) to extend shelf life and texture.

D. Avocado pit:

The pit (seed) of an avocado is not typically consumed and is not a source of dietary fat. Even the avocado flesh, while high in fat, contains monounsaturated fats, not trans fats.

Explanation

A. “If we could just eliminate cholesterol from the body it would help to solve the problem of heart disease.”

Cholesterol has important functions (e.g., hormone production, cell membranes). The body needs some cholesterol to function properly.

B. “So, if I eat healthy, I don't really need to worry about exercising.”

Exercise is an important lifestyle factor that works together with healthy eating to reduce cardiac risk.

While cholesterol is necessary, the body makes enough on its own. It’s not essential to consume dietary cholesterol.

D. “If I decrease my fat intake, especially saturated fats, and watch my portion size, this will be a start to improving my health.”
