The human body is that of a carnivorous animal,
it is evolutionarily designed to eat meat and gain nutrition from it, it is not prepared to be sustained solely by vegetables.
Several animoacids are not present in vegetable proteins,
... some vitamins are also predominantly present in meat, some vegetable components cannot be digested by our bodies
etc, etc, etc
Of course, there is nothing wrong in being a vegetarian
But you should always consult a nutritionist to make sure you are not damaging your health
I find my body has a tendency to tell me what it needs. A few weeks ago I suddenly wanted some BurgerKing really badly,
It seems to me that if I'm lacking something, my body will make it known.
If someone needs physical strength in their day to day lives, I just couldn't imagine them being able to have the energy and maintain their muscle without meat.
You can tell I'm not being very scientific about this.
All I know for sure is meat is delicious, and vegans are crazy.
The human is an omnivore.
The human is not 'designed'. The human body is adapted to be able to survive eating a both broad and limited diet. As long as you get all the stuff the human body needs to survive. Something which should be no problem for a vegetarian.
That's a stupid comment. There are only 20 different types. And just one protein may require up to 100,000 AAs. The basics of protein manifacture are the same in all life.
There's only B12 and that should be no problem for a vegetarian. Vegans should take suppliments. If they do the problem is eliminated and the fact their diet lacks B12 without the suppliments is meaningless.
You have only been able to name one problem, one that can be easily solved. You really have more?
Uuh, if a diet lacks specific amino acids and vitamins there is a lot wrong with having this diet.
Why should vegetarians do such a thing? And why shouldn't people that eat meat?
I suggest that all people that consume alcohol contact a nutritionist to make sure they don't damage their health.
The use of vitamin and other dietary supplements may change somewhat over the next few years, now that research is increasingly identifying that attempts to take in certain chemicals via dietary supplement medication rarely if ever succeed in providing the same levels of physical benefit that result from taking in the same chemicals from natural foodstuffs. This research is far from complete and, as yet, no firm conculsions have been drawn as to why this appears to be so (the fibre that is ingested as part of certain natural foodstuffs has been posited as affecting positively the length of time that the relevant nutrients remain within the system, as distinct from the pill-based ingestion where the beneficial chemicals may get flushed out of the system faster, or there could be other reasons).I mention this for a number of reasons, not least because the notion (as has been suggesed in this thread) that vegans should take artifical dietary supplements (containing vitamins and other things) specifically to make good the dietary deficiencies that result from their chosen régime is at worst potentially dangerous and even at best may be dubious in terms of general efficacy.
I won't expand on this too much here, preferring instead to cite just the single example of serotonin, found in far greater quantities in certain meats than in any vegetable products; serotonin, like many other chemicals present in foodstuffs, animal or vegetable, organically reared/grown or otherwise, is, to the human system, a drug capable of beneficial effects both psychological and physiological. When people tell me that they "don't do drugs" (in the sense of recreational, as distinct from medically prescribed, drugs), I understand and try to accept (as far as it goes) what they say but at the same time feel obliged to take it with abit of a "pinch of salt" (if you'll pardon the expression here!), since these people do actually eat, like the rest of us - ergo they "do drugs".
You are right. The stuff you say is just your meaningless opinion about how the reality should be.
What about human meat? I heard it is very delicious. Did you ever try it?
