My five y/o daughter starts school today and I asked her, if there was anything in particular that she would like to learn and she said she wanted to know how horses could survive on grass? I actually always wanted to know that myself lol... now all I have to do is paraphrase everything to her and it'll make sense. Thanks for making this video.

we can't eat grass because we took the herbivore upgrade path but didn't get "Rear Gut Fermenter" because we took "Omnivore" and the two are exclusive. Also in the early game we made the mistake of not picking up "cellulase" when we had the chance because we jumped the gun and changed our class to "Vertebrate" too soon.

Love how they mentioned cows make short chain fatty acids, which is actually what makes up most of their calories. Also non-rumenants aka hind gut fermenting herbivores use their caecum for cellulose digestion. In humans it's atrophied to the appendix though, but is still a good reservoir for bacteria for reseeding after infections or antibiotics.

Also, does it provide any vitamins/minerals? (possible solution to eating grass would be to grow a suitable organ for the proper cellulase producing microbes to thrive in, inserting it above the stomach)

@lupuscorvus841 8 жыл бұрын

Well, considering the fact that our stomachs don't have the enzymes to digest cellulose AND the fact that humans have a simple digestive tract which most closely resembles that of Carnivores, I'd have to say that is complete and utter bullshit. There's also the fact that our bodies are highly dependent on saturated fats for many functions in the body (which mainly come from animal sources) as well as proteins. The protein synthesis that our bodies undergo are mostly compatible with animal proteins as those are the most easily digested and absorbed by the body. Now, if you wanted to argue that the chemicals and hormones that they pump into our meat sources are terrible for you, then I'd agree with you vehemently. I also think animals should be raised in a healthier manner than spending their entire existence cooped up in some industrialized building living off of nothing but unhealthy grains and formula. But ultimately, eating meat is better for you than living entirely off of vegetation as most of the nutrients in plants cannot be absorbed by the body again, due to our bodies' inability to break down cellulose.

@lazsatori 8 жыл бұрын

Thanks for your response and passion. Everything we need can be gotten from nuts and seeds far better than animal sources. The issue is not about cellulose, that is fiber to us, and there are plenty of easy tricks to exposing the food. Cellulose is not a factor in digesting nuts and seeds, which has your saturated fats too! Yes, the toxins from the meat are terrible, but the microbe and parasite risk is far worse. And to the sensitive individual, the one who can perceive life as consciousness, the vibe is poor. Yes, Poor. Death consciousness is furtive and negative. Where living food awakens and quickens the spirit and mind..

In Vietnam, they eat bamboo. Not kidding. Bamboo is a type of grass, unless I'm mistaken. I also had it often while I was there for three months, it tastes exactly like you'd expect, like wood...but edible wood, easily the weirdest thing I've ever eaten. How does bamboo differ from regular grasses? I mean, clearly there's something there that animals other than ruminants like pandas and Vietnamese people and myself can eat otherwise we'd all have some serious issues. I mean, yeah them pandas got issues but they're still here for now.

Actually grass is the main source of food in the world. All grains are types of grass, so wheat, corn, rice, bamboo, canesugar, barley, and many others are all grass.

@naverilllang 8 жыл бұрын

we eat the grass seed, or grain. cane needs to be processed to refine sugar, and is too woody to eat straight up. bamboo stems can only be harvested the day that they sprout, and must be boiled to be edible, and even then only the inside can be eaten. otherwise, it's far too woody. so yes, grass is very important to us, but i think he was talking about why we can't eat grass from a lawn.
