Side Effects of Omega6 fatty acids

Intake of excessive amounts of omega6 fatty acids may lead to unwanted side effects. Particularly, it is thought that the ratio of omega6 fatty acids relative to omega-3 fatty acids should not be too large. The suggested range is 4 of omega6 to 1 of omega3, or even lower. However, many Western diets have ratios beyond 10 to 1.

Some potential negative side effects of high levels or ratios of omega6 fatty acids may include: arthritis, cancer, cardiac arrhythmia (dysrhythmia), heart attack, inflammation, mood disorders, osteoporosis, and thrombotic stroke.
