Vitamin K is necessary for total health. It makes sure calcium gets to the right places in your body, and keeps calcium out of the wrong places (your arteries). Vitamin K is best in the long acting MK-7 form, and only comes from eating animals and their parts. Vitamin K allows your body to undo damage. It actually removes plaques from the arteries. It is necessary for proper jaw and skeletal formation in babies, and pelvic formation in women. If you don’t get enough of it, you are likely to see little Jimmy gorw up with breathing problems and crowded teeth.
It makes calcium re-calcify. That’s right, bones are not rocks, they are living growing parts of us they heal grow, and act as the store of calcum for the rest of the body. Do you ever see wild animlas suffering from cavities? NO! They eat whatever the hell they want to! Do you see any other predator animals dying of heart attacks? NO! I am an animal, so are you. It works fundamentally the same way. Our bodies require things from animals that you can not get in any other form. Complete protein only comes from animal sources, and if you do not get those things, your body will break down your muscles to get the amino acids it needs.
Eating animals also contributes to getting your vitamins A and D, because they all work in synergy. Moreover, it just makes sense from an evoltuinary perspective
