I agree with you completely, no sensible vegans can ever contest that we were deigned to eat meat. Even the most ardent vegan scientists agree that human's are designed to eat meat, that is not in question.
That we do not have claws, talons, or incisors to hunt proves nothing. When early hominids ate meat they scavenged it, as vultures do, using their fingers to get the sinews and meat other animals couldn't. It was only after that that they began to hunt the meat themselves, and only much later they began to cook it. It is interesting that even now if someone was brought up eating raw meat he would have no problem with it.
The last few million years of human evolution have revolved completely around tools. We used advanced stone tools long before we began to hunt our own meat, and as such there was no need for evolution to bestow us with large claws or teeth to kill prey.
Simple research into human biology reveals how we are meant to eat meat. For one thing, our body produces hydrochloric acid and meat splitting enzymes that herbivores don't produce and are solely used for the digestion of meat. There are adaptations to our teeth (not incisors, rather the size of the jaw), stomach and intestines which have made a human being very adept at meat digestion. There is nothing wrong with the way our body digests meat, and we are so adept at eating it no scientists are of any doubt we've evolved to eat it.
In contrast, there are many reasons we aren't naturally herbivores. We cannot naturally get all the nutrients we need without animal products naturally. Vitamin B12 cannot be got, even now, without animal products or supplements, and a lack of it can cause anaemia and impending death. 60% of vegans even now have some level of B12 deficiency, as opposed to no meat eaters, which says something about how well adapted we are to a vegan diet.
All other nutrients can be got naturally. That owes to that vegetables can now be sold all year round, even out of season, and can be flown into the country from all over the world. In bygone times people could only eat the relatively small range of plants that grew in their ecosystem, and only when they were in season. Thus many more nutrients would have been unavailable and still more unavailable for most of he year. Until very recently it would have been impossible for a vegan human to live naturally without dying very quickly.
Now, meat makes up for all these lost nutrients very nicely, and it really shows how we aren't naturally vegans, as until very recently it was impossible to live like that.
As for coronary diseases, I quote.
"Despite claims that primitive societies are/were largely vegetarian, diets of native peoples the world over are rich in saturated fats and animal foods (28) and, as noted above, heart disease and cancer are primarily modern diseases. Saturated fat consumption, therefore, cannot logically cause these diseases. As with the poorly done studies of the Inuit, modern-day researchers fail to take into account other dietary factors of people who have heart disease and cancer. As a result, the harmful effects of eating refined sugar, nutrient-poor "foods," trans-fats (found in margarine and hydrogenated oils) and vegetable oils get mixed up with animal fat consumption.
It is commonly believed that saturated fats and cholesterol "clog arteries", but such ideas have been shown to be false by such scientists as Linus Pauling, George Mann, John Yudkin, Abram Hoffer, Mary Enig and others (29). On the contrary, studies have shown that arterial plaque is primarily composed of UNsaturated fats, particularly polyunsaturated ones, and not the saturated fat of animals, palm or coconut (30).
Trans-fatty acids, as opposed to saturated fats, have been shown by researchers such as Enig, Mann and Fred Kummerow to be causative factors in atherosclerosis, coronary heart disease, cancer and other assorted diseases (31).
A recent study of thousands of Swedish women showed no correlation between saturated fat consumption and increased risk for breast cancer. However, the study did show a strong link between vegetable oil intake and higher breast cancer rates (32).
The Framingham Heart Study is often cited as proof that dietary cholesterol and saturated fat intake cause heart disease and ill health. Involving about 6,000 people, the study compared two groups over several years at five-year intervals. One group consumed little cholesterol and saturated fat, while the other consumed high amounts. Surprisingly, Dr William Castelli, the study's director, is quoted in the Archives of Internal Medicine (July 1992) as saying:
In Framingham, Mass., the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower the person's serum cholesterol ... we found that the people who ate the most cholesterol ate the most saturated fat, ate the most calories, weighed the least and were the most physically active.
It is true that the study did show that those who weighed more and had higher serum cholesterol levels were more at risk for heart disease, but weight gain and cholesterol levels had an inverse correlation with dietary fat and cholesterol intake. In other words, there was no correlation at all (33).
In a similar vein, the US Multiple Risk Factor Intervention Trial, sponsored by the National Heart and Lung Institute, compared mortality rates and eating habits of 12,000+ men. Those who ate less saturated fat and cholesterol showed a slightly reduced rate of coronary heart disease (CHD), but had an overall mortality rate much higher than the other men in the study (34).
The few studies that indicate a correlation between saturated fat reduction and a lower CHD rate also clearly document a sizeable increase in deaths from cancer, suicide, violence and brain haemorrhage (34). Like the bone density experiments, such things are not told to the public.
Low-fat/cholesterol diets, therefore, are decidedly not healthier for people. Studies have proven over and over that such diets are associated with depression, cancer, psychological problems, fatigue, violence and suicide (35).
Children on low-fat diets suffer from growth problems, failure to thrive, and learning disabilities (36). Despite this, sources from Dr. Benjamin Spock to the American Heart Association recommend low-fat diets for children! One can only lament the fate of those unfortunate youngsters who will be raised by unknowing parents taken in by such misinformation.
There are many health benefits to saturated fats, depending on the fat in question. Coconut oil, for example, is rich in lauric acid, a potent antifungal and antimicrobial substance. Coconut also contains appreciable amounts of caprylic acid, also an effective antifungal (37). Butter from free-range cows is rich in trace minerals, especially selenium, as well as all of the fat-soluble vitamins and beneficial fatty acids that protect against cancer and fungal infections (38).
In general, however, saturated fats provide a good energy source for the vital organs, protect arteries against damage by the atherogenic lipoprotein (a), are rich in fat-soluble vitamins, help raise HDL levels in the blood, and make possible the utilisation of essential fatty acids. They are excellent for cooking, as they are chemically stable and do not break down under heat, unlike polyunsaturated vegetable oils. Omitting them from one's diet, then, is ill-advised (39)."
Now, one can eat no saturated fat and still have very high blood levels of it. Humans make saturated (alias animal) fat naturally, out of any excess calories. For this reason there is no specific link between meat eating and blood levels of saturated fat, any more than a veggie diet. As pointed out in the above quote, some vegetable fats, like those in margarines, are much worse for healthy than naturally occurring saturated fats.
Similarly your body on average creates four to five times more cholesterol than the average person consumes, and compensates by creating more when less is consumed. Cholesterol isn't evil, it is essential; it makes up the waterproof linings of all our cells and without it we would die. Too much can be bad, but as with saturated fats there are more healthy ways of disposing of it, like regular exercise. Anyway, it isn't so much how much cholesterol you eat, but how well your body handles it. A person who eats loads of dietary cholesterol and leads an unhealthy lifestyle can still have low cholesterol, and vice versa. Most people's bodies are able to take a large amount of cholesterol without getting atherosclerosis. For this reason that eating meat gives you heart disease is very misleading, and for the most part untrue. Of course, if you do have a problem eating loads isn't a good idea, but for most people there is nothing at all to worry about.
Mimi, in actual fact our digestive systems are much more like a dogs than a sheep's, we split away from them evolutionarily later. But nonetheless, even if that weren't true it'd make no difference to how our guts are designed, and that is to eat meat.
Neither would vegetarianism lessen world hunger, as there is already more than enough food in the world and every day huge amounts go to waste. The problem is economic, they're too poor to afford to import food should their meagre harvests fail. We can't give them free food because that'd bankrupt their own food industries. (who'd buy their food if there's free stuff floating around) and lead to the countries being even poorer.
The videos on the web only show the very worst, not to mention illegal, cases of slaughter. To suggest that that is even close to the norm is complete fallacy.
Shell, the ground animals use for grain could rarely be used for growing crops. For a start animals can be grazed on land unsuitable for crops due to climate, relief or soil quality. Secondly animal farming is much less intensive, a field of cows can still support wildlife, mostly due to that inefficiency you mentioned, a field of wheat cannot as it is stuffed full of crop. The poisons crops are sprayed with is also very bad for wildlife all the way up the food chain, and hawks routinely die from eating contaminated prey, so don't preach to me about the failings of animal farming.
Annie M, 157 people have contracted CJD (human form of BSE (mad cow disease)) ever. I don't think it's something you need to worry about.
Similarly Bird flu cannot be contracted from eating infected meat, you have to live in close proximity with infected birds for there to be even a chance (ie, they live in your house), and it's not in the UK or USA anyway.
