Trans Fatty Acids

Meaning

Trans Fatty Acids (TFAs) are a specific type of unsaturated fatty acid characterized by a double bond in the trans configuration, which imparts a straight molecular shape similar to saturated fats, making them solid or semi-solid at room temperature. These fats are primarily created through the industrial process of partial hydrogenation of vegetable oils, although small amounts occur naturally in meat and dairy. Clinically, high intake of artificial TFAs is strongly associated with adverse cardiovascular outcomes, making their reduction a key public health and nutritional strategy for longevity and metabolic health. They represent a significant dietary risk factor.
