Why are omega-6s bad for you if they're considered "essential"?
- First is simply that they're already overabundant. The ratio of omega-3 to -6 is the critical part, more so than the individual amounts of each. So too much of even a good thing (fresh and natural omega-6s) throws the body out of whack over time.
It only gets worse when they're NOT fresh and natural, as found in many commercial feeds that add abundant and inexpensive omega-6 sources such as corn oil to increase fat content. Unfortunately, during the refining process many of these oils are turned into molecular monsters. These trans-fats are often labeled as "partially hydrogenated vegetable oil" and they disrupt many cellular functions and wreak havoc in your horse's body.
So, although it's true that every horse needs the good version of omega-6s to be healthy, there is plenty available throughout natural grains and food sources to give him all that he needs. In contrast, today omega-3 is virtually absent from the food supply, and must be specifically supplemented.
