Grass feed cows therefore, can human feed on grass?

Question

Cows only feed on grass and they grow so big and healthy. Therefore, if human can eat cooked grass then there wont' be any more people died of hunger because grass are everywhere and its contain all the nutrition that mammal need just like the cows.

Answer 1

In fact, plant matter as food is not very nutritious.

- Cows and other herbivores have special symbiont bacteria in their digestive systems that help them to degrade (digest) cellulose, the main component of the wall of plant cells. We don't have such symbionts, and the parts of plants that we can actually digest and absorb are the ones that are softer and have higher content of other carbohydrates (starch, sugars, etc), or lipids and proteins (for instance, beans, dry fruits, etc.).

- Herbivores also have extremely long intestines for better absorption of this poor food. We don't.

- Grasses, during their long evolutionary history, evolved defenses against herbivores; they're not only fairly indigestible but also contain high amounts of silica (minute sand grains). That's why most specialized herbivores have ever-growing teeth to compensate the wear they sustain, another adaptation that we lack.

There are other technical problems with your proposal, including the fact that cooked grass would lose part of its nutritional value due to denaturalization of its molecules. The bottom line is that we are omnivores, not herbivores.

Answer 2

No, we need the actual meat from cows who can digest grass. Humans do not have the same enzymes that would extract all the nutrients and such from plants.

Answer 3

If humans could feed on grass it would destroy modern society. People would no longer need to work for money to buy food. If nobody is working society collapses. If someones hungry they simply have to go outside to their front lawns to eat or over to a large park area. Society charges you to eat so you will hold down a job. It's motivation.

Answer 4

Our human body cannot break down the cellulose found in grass.. that's probably one of the reason why we cannot feed on grass.. of course.. there might be exceptions too..

Answer 5

We do not have the digestive tract to handle raw grass like
cows do, but we ingest grasses like, lemon grass and the like
which are healthy for you. Ever have dandelion tea, or salad,
its very good.

Answer 6

That's a amazing. And grass gets its energy through photosynthesis of the sun's rays. So humans can perform photosynthesis, right?

Answer 7

No...cause our digestive system can't digest the cellulose contained in grass.

But in case you wanna cook it........well, you'd have to come up with a real good recipe to make it a popular dish!!!

Answer 8

Sure. But, would you want to? It's called wheatgrass and it's really good for you. One ounce is equal to two pounds of pure green veggies.

Answer 9

We could if we were herbivores but we are not and we need more protein sources than cows bcause our digestive system is different.

Answer 10

we cant digest grass
