Before we jump in I'll give you my disclosures. I take no outside funding or sponsorships for this podcast or any of my work. The only thing supporting it is my company http://NoseToTail.org that I started well after I understood the health benefits of including quality animal foods in our diet. In other words I have no outside interests influencing the information I present and I am not creating this content to sell my products. My foundational belief is that animal foods are healthy so I connected with the best producers around the country to help people purchase them. We raise them humanely and sustainably. We don't use additives or curing agents. Everything is all natural. We use the animals nose to tail.

We have products such as primal ground beef that includes liver, heart, kidney, and spleen for all the amazing nutrients and none of the hassle or taste you may not be used to. That's at http://NoseToTail.org We ship boxes straight to you and have free shipping options. We also have biltong if you want grass finished meat on the go. This is a traditional South African meat snack that's air dried, soft, and delicious. We have body care products made from beef tallow and only a couple other natural ingredients. We also have seasonings to go along with these wonderful products and make cooking that much easier. Make a custom box today at http://NoseToTail.org and take advantage of the free shipping options.

That's how these interviews are all possible along with all the other content we produce on youtube and social media. Thanks for supporting the ranchers, my other producers, and my team. The other way you can take advantage of this win-win-win situation is at http://Sapien.org where we have the Sapien Tribe. It's a private members community where you get the extended show notes for these podcasts, discounts on NoseToTail products, zoom calls with Dr. Gary and myself, and a lot more.
