Interestingly, I've noticed some "low PUFA" poultry operations who have their outdoor chickens on dirt rather than pasture. I must suggest that there's more to health than PUFAs. Most things are a bit more complicated than single-item fads tend to admit.
We got a call a few weeks ago, for example, asking if we could grow hogs without feeding any grains. "Research" has convinced many folks that this was the only way to lower PUFAs. Yes, we can do that, but it would take perhaps 50 acres per hog to let it forage all it wanted. At that land use rate, we'd need to charge more than $10,000 per hog.
While the Omega 6 and 3 ratios have certainly changed in recent decades and are indicated in various chronic maladies including inflammation, all omnivores were eating grain long before recent days.
My collection of antique agriculture books from even the late 1800s show chickens and hogs eating corn, wheat, barley, and other common grains. But not canola. Ahh, there's the rub. Fads tend to throw out everything, the proverbial baby with the bathwater, but this is simply the pendulum overcorrecting.
What has thrown our Polyunsaturated Fatty Acids out of whack is commercially feeding seeds developed for lubricants and diesel fuel, confining animals to eliminate dietary salad from pasture, creating unimaginable stress in factory farms and constant inhaling of fecal particulate, and denying exercise and sunshine. All of these fundamentally altered the many threads weaving together the PUFA tapestry.
Many years ago a patron sent Polyface eggs to a lab for analysis and found a substantial balancing of Omega 6 and 3 when compared with industrial counterparts.
We have not recently gone to the expense (it's substantial) of testing for PUFAs, preferring to put our effort into taking care of you wonderful patrons, making sure the animals have sanitary, hygienic, no-stress lives, and moving them onto fresh ground - honoring their original design.
In an analysis conducted a decade ago, Polyface eggs had 1,038 micrograms of folic acid per egg compared to 48 on the conventional industrial egg label. Yes, food can be medicine.
PUFAs are something, but they aren't everything.
One-thread fads come unstitched over time, and at Polyface we take a holistic and broad approach for practical balance. Thank you for trusting us with these decisions and we look forward to many more years of service.
