“I used to be the largest dairy consumer on the planet. I used to eat so much dairy and meat. The more that I looked into the dairy industry, the more that I saw that it was the singular, most inhumane industry on the planet, that we've all been lied to, including myself, for years. I always believed that the picture on the milk carton, the cow standing next to her calf in the green field with the red barn in the back was true. It’s certainly the complete opposite.” – Richard (Kudo) Couto Richard (Kudo) Couto is the founder of Animal Recovery Mission (ARM), an organization solely dedicated to investigating extreme animal cruelty cases. ARM has led high-risk undercover operations that have resulted in the shutdown of illegal slaughterhouses, animal fighting rings, and horse meat trafficking networks. Recently, they released a damning investigation into two industrial dairy farms outside of Phoenix, Arizona supplying milk to Coca-Cola’s Fairlife brand. What they uncovered was systemic animal abuse, environmental violations, and a devastating betrayal of consumer trust. While Fairlife markets its products as being sourced "humanely," ARM’s footage tells a very different story—one of suffering, abuse, and corporate complicity. Despite the evidence, this story has been largely ignored by mainstream media—likely due to Coca-Cola’s massive influence and advertising dollars.…

This podcast is Chapter 4 of my book Biology for Health Sciences. Life is based on chemistry and it helps to know a little to help us in our everyday lives, like why some fats are good while others are bad or why glucose and fructose are both real sugar. In this chapter, I cover metabolism, the four macromolecules (carbohydrates, proteins, nucleic acids, and lipids) and other vitamins and organic molecules Send us a text…

Where is every one? Why haven't we been visited by alien races, made contact with aliens, or even discovered a hint of an alien race? Ever since Fermi asked this simple question, people have been coming up with answers as to why we don't see aliens. Some solutions are scary, but I think a potential answer could be found by looking at our own solar system. Send us a text…
