The Poultry Paradox

Are your chickens truly grass-fed? Do you feed them any grains? These types of questions are plaguing pastured poultry producers around the country, and I wanted to get to the bottom of it to figure out why.  

It didn't take much Googling to stumble upon The Plant Paradox, a popular diet book, written by Dr. Steven Gundry, a well-respected cardiologist with many incredible professional accolades to his name, such as the largest number of Infant and Pediatric heart transplants to date, and the longest baboon to swine heart transplant, plus a host of medical device patents as well. He’s a well respected member of the medical community, so when it comes to hearts, it probably goes without saying, this guy probably knows a thing or two about hearts. Chickens, however, not so much.  

To summarize his dietary advice, he recommends avoiding all foods containing lectins. So, what are lectins, you might ask?  Lectins are protein molecules that bind to carbohydrates, and while there are dozens of different types of lectins that all behave differently biologically speaking, many act as anti-nutrients, like our old friend, raw soybeans. These proteins are found in many foods, especially legumes such as beans, and peas. They also lurk in whole grains such as lentils, corn, wheat, rice, barley, and many other commonly used grains. Lectins are also found in any fruits or vegetables containing seeds like apples, squash, nightshades, and many, many more. As you can see, the list of allowed foods is shrinking significantly when it comes to plant based ones.

Since lectins are protein, that should be a good thing, right? Well, the short answer is, maybe. Lectins primary function in plants are part of its natural defenses. Every living organism has at least one mechanism of self-defense, including the plants. Anyone who’s ever tried to grow tomatoes knows that bugs don’t show up until right when the fruit is ripening, and then seemingly overnight the damage is devastating. Even in The Plant Paradox, the author points out that prior to the introduction of the Granny Smith apple, it was known that eating green apples would produce very unwanted consequences. It’s really amazing how these systems are designed for the continued propagation of life!

For whole grains, those seeds are designed to fall from the plants and lay in wait until the time and conditions are right for germination. Meanwhile, others, like fruit & vegetable seeds and nuts are intended to be consumed and subsequently carried away. Only to be deposited elsewhere, far enough away from the parent plant or tree to not compete for nutrients, sunlight, or mere existence.  Can you think of a species more capable to carry away small seeds great distances than the avian species? The argument that nature wants these seeds to be eaten doesn’t fall on deaf ears, but who determines which species are the eaters and which of them aren’t?

For subscribers of the low lectin diet and advice given by Dr. Gundry, it is expected that poultry producers raise chickens not only physically on grass, but that we also do not provide them any sustenance outside what they would receive from foraging for plants and insects. Both in his book and on his blog, he has incorrectly labeled chickens as "insectivores" and makes the assumption this diet is obtainable and you simply need to make sure your provider of poultry follows his guidelines. Obviously as defined, chickens are omnivores and are not by nature solely insectivores, but rather they are opportunistic foragers. With highly acidic digestive systems, there is very little a chicken cannot eat making their diets very flexible based on their geographic location.

Before their domestication, chickens ultimately derived from jungle fowl, having a diet rich in seeds, insects, reptiles, tender green plants, small mammals, dead animal carcasses, fallen fruit, and most other opportunistic nutrition. This flexibility in diet allows jungle fowl to thrive in most environments. However, in those conditions, they do not reach maturity until 6 to 8 month of age and only reach live weights of approximately 2.5-4 lbs. Using even the most conservative calculations, these birds would have consumed over 25 lbs of foraged food during that time, and their resulting meat would possess a  tough/stringy and strong flavored quality. By and large, this is counterintuitive to what pastured poultry growers are trying to produce.

As prey animals, this also meant they spent the majority of their days under the protective covering of the tree canopy, and not out in open pasture for extended periods where they would be vulnerable to predation. It comes as no coincidence then, that chickens naturally lack the microflora to survive on plants and grass alone, making them unable to fully utilize their nutrients in the same capacity as herbivores.

Formulations for Low-Lectin/Lectin-Free?

It’s not uncommon for customers to regularly bring forth concerns regarding their personal diets and whether or not what the animals are fed is compatible with the resulting products we all raise, be it for meat or eggs. The organic and non-GMO choices aside, the largest specialty feed request to date, has been for chickens raised on feeds that do not contain soy.  Next in line, and increasingly more requested of late would be soy and corn free. Naturally, as you can see, more and more ingredient limitations are being placed on formulators of feed rations, such as Fertrell, to come up with solutions for these requests. Until now, most of these requests have been relatively achievable with reasonable effort and costs. However, with Dr. Gundry's dietary pillars of no or very little lectin fed poultry, most logic has left the equation on how to responsibly, sustainably, humanely, and cost-effectively formulate feed for chickens that meet the requirements of his diet program.

As pointed out, those pesky lectins are lurking around every corner, and unless poultry producers are willing to rip all their clover and alfalfa out of their fields, it would be impossible to remove all of the lectins from your chicken’s diet, since lectins have the highest concentrations in legumes. Meanwhile, you’ll still find those lectins present in other pasture grasses in varying amounts during their growing periods, especially leading up to their grain phases of development.

Contradictory Studies

The medical community is just like any other, it’s filled with many differing opinions. For every claim, there is a counter-claim, with both sides offering evidence to support their argument.

While there are claims backed by the numerous studies linked in the impressively long bibliography within The Plant Paradox, that removing lectins from your diet is good for prevention of cancer, there is research showing that those same lectins contain anti-tumor properties  (Gastroenterology. 2002 Jun;122(7):1784-92), and another that demonstrates lectins showing promise as a potential cancer treatment as they bind cancerous cell membranes causing inhibited cancer cell growth. (Crit Rev Food Sci Nutr. 2005;45(6):425-45.)

There was recently a study in Finland that concluded that there are “too many studies” for  scientists; that they “are unable to processed the information”. (https://arxiv.org/abs/1503.01881) It’s a never ending saga trying to keep up with the more than 2.5 million new studies across nearly 30,000 different journals annually.

So while Dr. Gundry may have been able to connect a few dots within his research and his patients, it goes without saying, that more studies are needed as they pertain to chicken.  

Due to the significant number of potential variables regarding the impacts of lectins on poultry, and the resulting effects on the consumer of those products, it hardly seems wise to up end your operation for what really may only account for a small percentage of your base until further research can be done.

Sorting through "USDA Organic" Deceptions..

From the Pastured Life April 28, 2021 Newsletter:Sorting through "Organic Chicken" Deception..In this newsletter, we are going to dive a little deeper than we normally do on issues very near and dear to our hearts. We have had many conversations with a lot of you out on our delivery routes, in email, and on the phone and normally the topics are the same regarding the differences in "Organic" products in the store and of course what we produce on our farm. Find reference links embedded below throughout. I would recommend going back to the links after reading the article fully.First, let us discuss the problem with "Organic" Pastured poultry products in the store.Under current USDA regulations, these are the three key criteria for all certified organic chickens:1. No antibiotics or drugs, ever2. Fed certified organic grains3. Access to pasture Seems easy enough, right?Guidelines for Organic Poultry:https://www.ams.usda.gov/.../Poultry%20-%20Guidelines.pdfI'd like to let you in on a few dirty little secrets of the organic poultry industry. Let's unpack these one at a time. First, let's tackle antibiotics & medications.Did you know that over 2/3 of the world's supply of antibiotics is used for livestock?!?! I think we can all agree that excessive use of antibiotics is bad for animals, consumers, and the environment, and it's no coincidence that we're seeing a large recurrence of antibiotic-resistant infections like MRSA and antibiotic resistance even in young children as a result. The organic rules clearly state that the birds can not be fed or administered any drugs, including antibiotics and antiparasitic medications, but in giant confined poultry houses things like coccidiosis run rampant in flocks of 30K+. The poultry industry and pharmaceutical companies have found a loophole - vaccination programs are allowed. Now hatcheries can spray chicks with coccidiosis medications and simply call it a vaccination program to be in organic rule compliance.That certainly doesn't sound like no drugs EVER to me. Chick spray cabinets used to skirt the rules: https://5mpublishing.sirv.com/.../contents/CF1Para.pdfSecond, and this is a BIG one.Nearly 80% of the organic grain used in livestock production in the US is imported, and half of that grain travels through Istanbul, a port that is rampant with fraud. The USDA has acknowledged the fraud risks only after the Cornucopia institute completed a multi-year investigation into imported organic grain fraud. To make matters worse, in several countries or origin, the amount of acreage under organic certification did not correlate to the amount of grains and legumes produced. In some cases, the exported crop(s) exceeded nearly TWO TIMES the amount of acreage to produce said crops. You can read more about this here: https://www.cornucopia.org/.../looking-at-fraud-industry.../These problems aren't limited to import grain markets either. They happen here and schemes like this one make the news every couple of years, so it's getting harder and harder to know who to trust and when you can trust them.https://www.kansascity.com/.../crime/article239079858.htmlIn this case, the USDA was completely unaware, and the situation only came to light after a competitor grew suspicious based on abnormal prices and volume of organic corn and soy that he was moving exceeded the supply in their region.This brings us to the third requirement: access to pasture. We've all seen the packages of chicken in the store, each with its own images of chickens roaming on picturesque green pastures. The sad truth is, NONE of those chickens ever saw a blade of grass or chased a bug; and for many, the first and only time they ever saw the sun was on their ride to the factory for harvest. Organic chicken houses have tiny doors that open to sun porches, but they are seldom open - and with nothing other than dirt outside, there's little reason for a chicken to ever venture out. The National Organic Standard Board (NOSB) serves as an advisory board to the National Organic Program (NOP) who is in charge of rulemaking for the USDA's Organic program and FORTY of the board members of the NOSB have recently penned a letter to the Secretary of Agriculture, and among their list of requests, is for the USDA's organic program to enforce the pasture rule for organic poultry. Stating that "public trust in the USDA organic seal is faltering due to highly public examples of poor enforcement of the pasture rule."  https://www.cornucopia.org/2021/04/letter-to-secretary-vilsack/This is why it's never been more important to know your farmer. This is why we choose to buy our non-gmo feed directly from the farm that grows it. This is why we buy our day-old broiler chicks from a small, local hatchery that we can visit and know exactly where our chicks come from. This is why we raise our birds on pasture. Why? Because our family deserves this, our patrons deserve this and if you're paying $8.50 lb for "Greenwise" chicken at Publix or $9.00 for organic chicken at Whole Foods, you should get what you are paying for. Inspect what you expect and don't fall for the marketing and misdirection.

The New Pan-Normic?

I can see it in everyone's eyes when I come to town every week, it's a feeling in the air, almost like everyone is holding their breath. What will our new world look like, what will we take forward from before and what will we change and make better?
