Essential Fatty Acids
(must come from food)

Superunsatruated Omega-3 Family (W3)

  • Alpha linolenic Acid (LNA)
  • Stearidonic Acid (SDA)
  • Eicosapetaenoic Acid (EPA)
  • Docosahexaenoic Acid (DHA)

Polyunsaturated Omega-6 Family (W6)

  • Linoleic Acid (LA)
  • Gamma linolenic Acid (GLA)
    • inhibitors include:
      • "high levels of carbohydrates in the bloodstream, which slow down delta-6-desaturase activity and decrease GLA production;
      • trans fatty acids which inhibit delta-6-desaturase;
      • viral disease;
      • elevated adrenaline (decreases delta-6-desaturase) and cortisol (due to stress) levels which increase insulin levels and lead to excess arachidonic acid production via activation of delta-5-desaturase enzyme. Since activation of delta-5-desaturase depends on insulin, and insulin is balanced by glucogon (which inhibits delta-5-desaturase), it is critical that insulin/glucogon levels are kept in balance." —Breast Milk, Infections, Iron, GLA, EPA, and Asthma
      • "trans-fatty acids from margarine, vegetable shortening and commercially processed vegetable oils hinder D6D (Delta-6-Desaturase) and its vital co-workers-vitamin C, vitamin B6, vitamin B3, zinc and magnesium." (From GLA: The "good" omega-6, by Ann Louise Gittleman, Total Health for Longevity magazine, September 2000. Gittleman recommends Borage Oil (ignoring the problems with it that make Evening Primrose better for some people).
    • Sources:
      • Borage oil contains GLA but in some people's metabolisms (especially those with high insulin, see above) the long-chain fats in it are converted to arachidonic acid.
      • Better: evening primrose oil, no long-chain fats
  • Dihomogamma-linolenic Acid (DGLA)
  • Arachidonic Acid (AA)
Monounsaturated Omega-7 Family(W7)
Palmitoleic Acid (POA)
Monounsaturated Omega-9 Family (W9)
Oleic Acid (OA)
Saturated Family (W9)
  • Stearic Acid (SA)
  • Palmitic Acid (PA)
  • Butyric Acid (BA)
  • Arachidic Acid
