Can anyone point me to some actual evidence that eating meat will make a long-time vegetarian ill?

Everyone always brings this up, but it strikes me as complete nonsense that people could completely lose the ability to eat animals in a single lifetime. So are there actually scientific studies documenting this, and if so, can you list a few?Can anyone point me to some actual evidence that eating meat will make a long-time vegetarian ill?
Actually, no, I cannot do that for you. I think it is a long-believed rumor.

After I had been a vegan for about 10 years, I decided to have a hamburger.. I chose a fancy sit-down hamburger restaurant with fancy hamburgers (this was about 30 years ago -- the hamburger cost me about $10 then). Many of my friends, even meat-eaters tried to discourage me, and told me I would get sick, but I would not be dissuaded.



I enjoyed my hamburger, and never felt any untoward symptoms.

Okay, perhaps I might have felt "heavier" afterwards, but, even if you only eat cooked vegetarian food, or even serious raw vegan food, you can feel "heavier" afterwards, particularly if you indulge in "special" restaurant dishes.



As a nutritionist, I do know that, if you eat meat, you do place a greater strain on your digestive system than if you only eat vegetarian dishes. At the same time, if you are not practicing proper food combining, even vegetarian or vegan food. and, yes, even raw vegan food can place a strain on the digestive system, and possibly cause indigestion of some sort.



So many people say that you might not feel well after you eat meat. I wonder why. It might be psychological. If you expect to feel bad, you probably will. If you don't expect to feel bad after dinner, you probably won't.



I know this all flies in the face of what vegetarians and vegans say, but it reflects my experience. (anyway, if it weren't so, all of those people who have gone back to eating meat after observing a vegetarian diet for six months or so would never go back to eating meat - the first try would convince them that they were doing something terribly wrong) This is not to say that I do not believe that being a vegetarian is a healthier choice. I am a raw vegan and have been so for many years. I think it is healthier for me. At this point, I cannot tell you that it makes me feel better simply because I have been doing it for so long that I don't have any good point of reference.
I'm not a vegetarian. I'm an omnivore, live on a permaculture farm, and we raise 90% of the food we eat (even meat and dairy). I also worked in the medical field for over 15 years.



People who make a lifestyle choice to cut out and not eat a certain type of food will indeed loose the ability to eat that food over the years. It doesn't matter what the food is. Meat, dairy, fruits, vegetables, whatever. If a person goes long enough without eating it, they will have lost the ability to digest it if they try it again years later.



The human body has enzymes to break down foods. If you are no longer eating a certain type of food, your body will decrease, and eventually stop producing that enzyme over time.



So years later a vegetarian eats meat, they become ill, because their body cannot digest the meat.



This however is not a permanent problem. Anyone can develop the proper enzymes again (as long as they do not have actual food allergies). They just have to start with very small amounts of the food, and allow their bodies to adjust, and begin to manufacture the enzymes again. It takes about three months to properly readjust your body, so it can once again deal with, and digest the food chosen to once again eat.



Remember it's with ANY food, not just meat.

physically our bodies are not meat -eating bodies.



Humans, as all plant eating animals, have long, twisting and quite comlicated intestines, full of nodules and holes and pockets, which hasve enzymes specifically designed to absorb water vitamins and mierals in the large intestine, which is the point where most of the water from the food is absorbed.

Meat eating animals have a smooth, short intestine, which is only designed for the absorbtion of fats and salts, not water, not vitamins or minerals.



These meat eating animals have fangs.

They have extremely packed muscles, fangs, and walk on all fours.





PLant eating animals have flat teeth, and need the water from the plant sources they eat, to flush the intestine out, and this is also the purpose of the fibre in the foods the eat- the gently sweep out the remnants of the waste food, and to clean out the intestine.



Human beings make their own cholesterol within their diet, and get sick when they eat animal cholesterol. Not immediately , but after time, when enough animal cholesterol builds up ion their arteries, they get sick, tired, and often die with the white gummy substance they are not naturally designed to eat.



Humans can eat animal meat, but after a long time, it makes the human body work far less well.

Arteries become thick with cholesterol, organs like the bladder, and stomach start to form cancer and the colon too, this is due to constant waste preduct from the meat allowing to sit and rot and leak its ensymes into the system.



WHen cooked meat is eaten, it is useless compared to the raw version. The meat is rubbery, and sold, and any nutrients inside it are solid and can't leek into the blood stream. You can't break down a lump of cooked meat, it won't leak protein or anything, even if you put it in vinegar.

S o it just sits in the intestine and is hard to shift, it leaks the rotting matter into the bloodstream and created build up of toxins.

THat is the start of disease and so anyoine eating this food can get ill from it.



It's not going to happen overnight.



Humans can eat paper too, and mud and it will sustain you for a bit, but after a while you'll get sick, i

ts all plant matter so it works for a short time.



A vegetarian who's eating meat for the first time won't get ill necessariily. Unless the pork is really rich, opr has worms and the vegetarian has a sensetive digestion.



If the vegetarian eats meat they're not going to fall over and die- if the fish or meat is loaded with mercury or hormones, they might get a headache or physical reaction like that- but that IS getting ill.



A headache from your food is illness from the food.

If you're waiting for a much heavier disease, they will go right into the poop if peaple eating cancer producing foods, and will start to feel constipated ( an illness), bloated and heavy and might sweat more acidic sweat ( an illness), unitl they mught develop cancer just the same as any other meat eater.



A lifetime of being vegetarian and eating loads more vitamins and fresh foods may help them of course, but food is a day to day thing. You don't just eat a salad one day and think' Phew, I'm thin for life:", you have to upkeep it.



No human is naturally a meat eater.

That doesn't mean, that when you eat sand ( my cousin does, she's three) you will die, or that if you eat ree bark you will die.
I don't believe that any actual study has been done to "prove" any of this. However, personal experience tells me that it does. I have been a vegetarian for 13 years. After eating what i thought was normal red beans and rice, I was violently ill, digestive-wise (we're talking gut-wrenching pain and diarhhea for 3 days straight). I found out several days later that "oh yeah, i guess I did put pork in there" from the cook. i was the only person affected by any sort of digestive issue, and i was the only long-time vegetarian to have eaten it. I was not sick beforehand, and had no other symptoms beyond the internal ones of any other illness. After 3 days of hell, I went back to feeling my healthy self.



All of this is anecdotal of course, and i'm sure that there are people who might not react so violently to re-introduction of animal products. But after some time with your body unfamiliar with digesting animal proteins and the like, sudden introduction would be a shock to anyone's system.Can anyone point me to some actual evidence that eating meat will make a long-time vegetarian ill?
this girl I used to go to school with has been a vegetarian all her life and now she can only eat really small amounts of certain types of meat because it made her anemic or something-I'm not entirely sure though because that's just what someone told me. It's something to do with her blood anyway

hope this helps
Yes there are studies saying that. It is because if you have been a vegetarian for a very long time, your body is not used to meats, and only plants. If a vegetarian ate meat after a very long time, they do get really sick.
after a while you lose the bacteria in your stomach to digest meat. if you start out slow and build up, your body will start making the bacteria again. if you have a regular meal of meat after being away so long ,you will get violently sick. ask your doctor
I have a good friend who is primarily a vegetarian, because he feels ill after eating meat. He does not know why this is.

Unlike most vegetarians, though, he does not criticize me for the fact that I hunt and eat meat.
If you don't eat meat for extended periods, specific bacteria in your digestive system are no longer present. Without that bacteria to help break down specific parts of meat, could in fact make you sick.
I fell off the vegetarian wagon for a bit over the summer and ate a shrimp. My stomach couldnt break it down for a few days. It was uncomfortable because it was just sort of "stuck".
I was born a vegetarian. Can't even stand the smell .

I am pushing 70 and my last medical tests shows everything normal.

Except a slight sugar problem and a little high blood pressure.
No. No one can provide you with this evidence. Your body doesn't lose the ability to digest meat. If one has a problem it's mostly psychological
Probably, yes.. Because your digestive system gets used only to veggies... but I'm not sure, ask your doctor.





Have fun ;)
