Man-made trans fats and natural trans fats in dairy and meat are made of different chemical parts, and these differences might affect your health in different ways.

Trans fats in food come from two places: factories that process oils, and the stomachs of cows and other grazing animals.

A type of fat found in milk and meat turns into another fat called conjugated linoleic acid in the body, and that second fat might be good for your health.

Some studies suggest that the natural trans fats found in milk and meat might not raise heart disease risk the same way that artificial trans fats in fried and baked foods do.

Not all trans fats are the same — some might be more harmful, and others might be less harmful, depending on where they come from.

Trans fats from dairy and meat don’t seem to harm cholesterol or cause inflammation like the ones made in factories — some might even be a little good for you.
