GLOSSARY

Gamma-Linolenic Acid (GLA) is 18:3 n-6, in a different omega family from ALA despite similar bond count, and occurs in evening-primrose and borage oils.

In fatty-acid notation, the number before the colon usually gives carbon count and the next number gives double-bond count. An omega family or bond position may follow. This is not an intake weight or recommended dose. Distinguishing some isomers also requires specifying bond positions and spatial geometry beyond the basic code.

The omega number locates the first double bond from the methyl end, which differs from the carboxyl end. Total carbon number and total double bonds are separate information. Omega therefore names a structural family rather than a quality score or speed of action; members can differ in length, food sources and function.

Omega-6 includes essential dietary fatty acids and should not be labelled uniformly inflammatory or harmful. Fatty-acid-derived mediators have diverse, tissue-dependent actions. Replacing saturated fat with suitable unsaturated sources differs from adding unlimited oil. Interpretation should therefore reflect the food pattern and actual intake rather than treating an entire family as a toxin.
