Linoleic acid is found primarily in seeds, nuts, grains and legumes. Alpha-linolenic acid muscle pain is found in muscle pain the green leaves of plants, including phytoplankton and algae, and in selected seeds, nuts and legumes (flax, canola, walnuts and soy). Arachidonic acid (AA) and docosahexaenoic (DHA) acid muscle pain are obtained directly from animal foods AA from meat and poultry and DHA and EPA from fish. When addressing the issue of essential fatty acids in vegetarian diets, three key questions arise: 1. How much omega-6 and omega-3 fatty acids do vegetarians need? 2. Do vegetarians convert alpha-linolenic acid to EPA and DHA in sufficient quantity? |

Humans have the ability to convert the linoleic and alpha-linolenic acid to longer chain fatty acids, which serve as precursors for eicosanoids. Eicosanoids formed from arachidonic acid (AA) (omega-6 family) have the potential to increase clogged arteries blood clogged arteries pressure, inflammation, clogged arteries platelet aggregation, thrombosis, vasospasm, allergic reactions and cell proliferation. Those formed from eicosapentanoic acid (EPA)(omega-3 family) have opposing affects (4,5). Omega-6 and omega-3 fatty acids are not interchangeable; we must consume both. These two families of essential fatty acids compete for enzymes involved in their desaturation, thus the excessive consumption of foods rich in omega-6 fatty acids may compromise the conversion of alpha-linolenic acid to EPA, with adverse affects for health and disease. Current research suggests that the levels of essential fatty acids and the balance between them may play a critical role not only in growth and development, but also in the prevention and treatment of chronic diseases including coronary artery disease, hypertension, type II diabetes, arthritis and other immune/inflammatory disorders, and cancer (6-11). |
