Eating with the Season: Pastured Eggs

Eggs are most plentiful in the spring and summer. The days are longer, the temperature is warmer,

and hens lay more eggs when they have more sunlight and when it’s warm. Chickens are tropical

birds. Longer days and warmer weather agree with them. They are more comfortable in these

conditions. They are stressed when it’s cold and dark, so they produce fewer eggs in the fall and

winter. So you might say that eggs are a seasonal food, just like strawberries and tomatoes are.

Eggs are more nutritious in the spring and summer. The hens are eating grass, worms, and insects that

aren’t available to them in the colder months. The nourishment they receive from this diet can’t

compare with what’s available in the fall and winter. As a result, eggs laid during warm weather have

a much higher nutrient content. Two of the more important ones are conjugated linoleic acid (CLA)

and choline. CLA confers many health benefits such as protecting against cancer, type 2

diabetes and heart disease. Choline is essential for normal neurological function and a healthy brain,

and it’s not found in many other foods.

Eggs from hens raised on grassy pasture have the correct balance of omega-3 and omega-6 fatty

acids, which helps reduce inflammation and promote healing and regeneration. This balance is

shifted when the hens consume more grains after the grass stops growing and the insects are gone.

How can you tell if an egg is nutrient-dense? Crack it open and look at the yolk. If it’s deep golden-

orange, it’s loaded. Ever notice how the winter egg yolks are pale in comparison? In general, intense

color equals superior nutrition most of the time.


Polyface does not provide artificial light or heat in the hoop houses in the winter in order to keep the

hens laying year-round. Nor are they given hormones to stimulate egg production. Instead, they are

allowed to rest as part of their normal, natural life cycle. They molt and replace their feathers every

winter, too. The process takes about 6 weeks. They completely stop laying while all their energy

resources go into growing new feathers.

Over the past 12 years or so, I have noticed that Polyface customer demand for eggs reaches its zenith

in the fall and winter, and drops dramatically in the spring and summer. Every year, the trend seems

to be out of sync. Technology allows us the luxury of buying almost any food all year round. We’ve

become disconnected from the rhythm of the seasons.

Dr. Buck Levin writes in his book, Staying Healthy with Nutrition, “Nourishment is a connection

between our inward health and the most distant reaches of the Earth. We break with this connection

when we live in an isolationist, separatist, exclusionary, exploitative, and extractive way, and we

restore it by being inclusive, accommodating, integrative, and considerate. When all is said and done,

nourishment is about the connection, not the payoff.”

Instinctively we know that food is most delicious and nutritious when it is grown and harvested in

season. Take advantage of this principle. 

Polyface hens have emerged from their winter shelter, and are now on the pasture.

Reconnect.

May you be deeply nourished.

Food Shortages

I'm in Oregon today speaking at the Azure Harvest Festival and a question from the audience during a Q&A stimulated a lot of discussion:  "What do you think about the possibility and preparation surrounding food shortages?" David Stelzer, founder of Azure Standard, answered that the issue is not food volume, it's food nutrition.   That was an interesting answer that has a lot of merit.  As a nation, we are overfed and undernourished.  This is the crux of the MAHA movement and the epidemic diseases we see in our country. At Polyface, we know the pastured meat and poultry we produce is far superior in essential phytochemicals and other nutrients due to the carotenes, exercise, and stress-free habitat we offer.  You can taste the difference, feel the difference in texture, and measure it empirically. Perhaps my most poignant affirmation was our cat test.   We purchased meat from the supermarket and offered our own for the four cats.  They wouldn't touch the conventional meat (ground beef). Even though two plates and four cats would be much easier to accommodate if they spread out, all four crowded around the plate with our meat, eating it all and licking it up, before later sniffing and gingerly eating the supermarket counterpart. Since cats don't understand TV ads or USDA propaganda, they know what's good and what's not.   We encourage anyone dismissive of food differences to ask their pets:  you can trust them far more than doctors and experts. Yes, I get the nutrient deficiency angle on the shortage question.  But I'd like to explore it a bit further.   Right now, the world throws away more human-edible food, as a percentage of production, than at any time in human history.  The planet is awash in food.   Some 40 percent gets thrown away because it has a slight blemish, exceeds the sell-by date, or is tainted in some way.  We have a fundamentally segregated food supply rather than an integrated one, and that creates a lot of unusable waste. The vulnerabilities of our food system, I think, are much more subtle.  When I was in Uruguay two years ago, speaking at a conference, one of the other presenters was from Germany and showed a soil map of the globe.  Not a single commercial agricultural region had a stable or positive soil trajectory.  Every single area on the planet is losing soil; some faster than others, but globally our soil depletion continues without any sign of abatement. This is not a good trajectory.   As much as the technocrats promise food without soil, that's not the way to bet.  Soil is the skin of the earth.  When it goes, famine results.   The main difference now compared to centuries ago is that we have the capacity to move food around.   Nobody starves due to a lack of food on the planet; they starve due to socio-political unrest and dysfunction. But what happens when massive areas can't grow anything anymore?  Even being able to move food around doesn't help when there isn't enough.   The soil trajectory does not look good.  But at Polyface, we're building soil.  Areas covered with shale (layered rocks) half a century ago now have a foot of soil on them.  That's not the 3-5 feet that 150 years of inappropriate tillage eroded, but it's a build-back start. In addition to soil loss, as a planet we're seeing hydrologic decreases.   The Oglala aquifer, which undergirds the irrigated agriculture in five states, has dropped more than 100 feet in the last half-century.  At its current rate, it will be unpumpable in about 50 more years.  Imagine if all those circular irrigation pivots in Nebraska and Kansas shut down.  What then? At Polyface, we keep building ponds to inventory surface runoff.  By definition, surface runoff occurs when rains come too fast at once or too much at one time for the soil to absorb it.  Holding that and using it strategically in a drought is a way to reduce flooding during rain events and grow grass when it gets dry.  This is one of the most landscape resilient techniques we can implement. Finally, major animal and plant diseases threaten the world's food systems like never before.   African swine fever, hoof and mouth disease in cattle, and bird flu in poultry appear to be getting worse and covering larger areas.  Why?  We believe it's because chemicals and factory farming compromise the immunological systems in both plants and animals.  Monocrops and chemical fertilizers wreak havoc on immune systems, opening the planet's food systems to new levels of fragility. In contrast, at Polyface, we believe happy animals and biodiversity offer the best antidote to immunological deficiency.  Stress from unsanitary conditions, mono-species density, or dietary deficiency (rations or fertilizer) invites disease.  Nature uses disease to cull the weak.  Predators pick off the stragglers.  This is the way biology works. But at Polyface, we keep these vulnerabilities at bay with compost fertilization, pasture rotations, and lots of species diversity, including pollinators and wildlife. Here's the point:  the basic long-term vulnerabilities in the planet's food systems could all be reversed with practices Polyface uses every day.  Looked at another way, the entire food shortage question could be answered if eaters and farmers implemented these ecological and immunological protocols, working together to rather than completely separated.  We don't need to fall into an abyss of starvation. If we all simply began eating food from farms that build soil, increase water, and stimulate immunity, we could deliver a hospitable, abundant planet to our children.   Reversing these trajectories wouldn't take much time or money.  It takes intentionally-minded folks who connect the chain of sustenance from their plate to the planet. Polyface patrons do that.  Thank you.  Let's heal the land together. Joel
