Fat is flavor. It’s such an important component of our diet because it carries many of the aroma compounds that make food flavorful and delicious. Fat is also important nutritionally. We need fat to make cell membranes and important signaling molecules like steroid hormones and prostaglandins.

Most of us are familiar with how dietary fat is divided into saturated, monounsaturated, and polyunsaturated fats. But in each of these classes exist several individual species of fatty acids. For example, palmitic acid is a saturated fatty acid with 16 carbon atoms and stearic acid is a saturated fatty acid with 18 carbon atoms. Stearic acid may be particularly important for maintaining healthy body composition. It has been shown to be beneficial in regulating energy metabolism in fat tissue in both human and rodent studies.

Stearic acid

Stearic acid (C18:0) is a saturated fatty acid found at high concentrations in animal fats and cocoa. This particular saturated fatty acid has been studied a lot over the last decade because it seems to have biochemical properties unique from similar types of fatty acids.
