animal nutrition > plant nutrition. Gram for gram.
and there are essential nutrients in animals that you just cannot get, from plants.
1 cow can feed a whole person for a year.
Which is weird. I don't know how they even hold the fork.
Nice one, Doug
Well obviously it doesn't hand feed the human
It barfs pre-chewed grass into the humans mouth, much like a bird feeds its young
The first two statements are bold claims to make I'd like to see some credible sources on this.
The last one which I'm also not sure is true one could put in context. E.g. as a comparison how much acres of land/ water/ energy does it use compared to vegetables.

Basically it's harder to achieve all essential amino acids in a plant based diet. Animal protein is also linked to lower stroke risk and diabetes, but can lead to higher heart disease. Overall it's not absurd to say animal protein is better than plant protein.
On the last comment: https://rainbowrunfarm.com/how-many-people-can-a-cow-feed/
This source claims one cow can feed one person for 8 years, but that feels a bit absurd so I did my own math. 80% lean beef contains 1152 calories per pound. Meaning at 2000 calories a day one person eats 1.74 pounds per day.
https://beef.unl.edu/beefwatch/2020/how-many-pounds-meat-can-we-expect-beef-animal
This source claims about 880ibs of useful meat is available on the average cow, meaning one person can survive for 505 days on one cow, or 1.38 years.
The third source claims one acre per cow raised is the land needed for grazing. Checking other sources this seems to be the general consensus on cattle to acre ratio.
https://permaculturism.com/how-much-land-does-it-take-to-feed-one-person/
This source claims you need 1.69 acres of land to raise all the required plants in order to feed yourself for one year. Therefore raising the cow and eating it would be a more viable space.

And where do the animals get them from?
Omega 3 fatty acids, vitamin B12, vitamin D3, vitamin A, choline, etc...
Many animals are capable of synthesizing these compounds, but humans are not. Our bodies stopped producing them since we could get them through our omnivorous diet.
Vegans can of course take supplements for these, so you can get enough of them, but you do have to think about it and take the right supplements to prevent deficiencies.
Flax seeds, walnuts, seaweed, Canola/rapeseed oil, Hemp seeds, edamame/soybeans, and chia seeds to name a few.
Seaweed, tempeh, unspecified fermented vegetables, mushrooms, fermented tea, and of course, as with most animal carcass: artificially enriched foods
Allegedly lichen (that's the source for all the vegan supplements), and this study claims that there is evidence for d3 in other plants
"Vegetarian and vegan diets can provide sufficient vitamin A in the form of provitamin A carotenoids if the diet contains carrots, carrot juice, sweet potatoes, green leafy vegetables such as spinach and kale, and other carotenoid-rich foods"
Oat bran, Apples, Oats, Avocado, White Rice, Banana, brown rice, Blueberry, Wheat bran, Cantaloupe, Wheat germ, Grape, Grapefruit, Navy Bean, Orange, Peach, Olive oil, Pear, Peanut, Prune, Soybean, Strawberry, Tofu, Watermelon

This is a blanket truism for any diet. The average American diet, for example, shows a lack of Calcium, Iron, Potassium, Magnesium and Vitamins A, C, D and E
All those plant based alternatives are significantly lacking in most of those nutrients, and aren't readily absorbed from plant based sources. You have to eat a shitton of them to reach the levels easily attained by eating a few animal products. Most vegans are absolutely deficient in them.
And for more you have Iron and Zinc which our bodies don't readily absorb from plant based sources.
Calcium and cholesterol are signifantly lacking in vegan diets. Carnatine and carnosine. The other vitamin Bs.
Sure, but it's extra true for vegan diets due to our bodies inability to fully digest most plants, and readily absorb the necessary nutrients from them.
Source? For pretty much any claim you just made?
Search engines are your friend.
I'm glad I really enjoy meat and dairy because as much as I want to eat other stuff I get really sick especially with any grain or fruit.
🤔 Maybe you have a gluten sensitivity or allergies
