What is a beneficial Trans fat?

• A. Conjugated linoleic acid (CLA) found in milk and butter
• B. Hydrogenated vegetable oils
• C. Short-chain fatty acids from refined sugar
• D. Trans fats from grilled vegetables

Answer: (A)

Some trans fats can be beneficial; the best example is conjugated linoleic acid, which is found naturally in milk and butter. CLA is a trans fat, but unlike the industrial trans fats created by hydrogenation, it has been linked in some studies to favorable effects such as improved body composition and potential anti-inflammatory or anti-carcinogenic properties. However, the evidence isn’t definitive, and intake should still be moderate.

The other options don’t fit because hydrogenated vegetable oils contain industrial trans fats associated with negative cardiovascular effects; short-chain fatty acids from refined sugar aren’t trans fats; and trans fats from grilled vegetables aren’t an established or meaningful source.
