The redneck strike again.

[Confused Ape]

Let me explain in simple terms.
When you get a real scare your blood build up a chemical reaction
creating toxins.
After the scare goes away your blood return normal however this
does not apply to animals that are going to be killed in abattoirs.
As the scare and the smell of death does not go away then the
toxins stay in the blood and the meat so when you eat meat you
also eat those toxins that are in the meat.

If you look in some medical info. you will find more about these
chemical reaction that build up toxins.
I just make it simple.

Can you provide links to reputable articles explaining these toxins, please. You know what you're looking for. What I did find, however, was this in an article about factory farming.

You Are What Your Food Eats

Scientists at the USDA Agricultural Research Service have found evidence linking animal stress to the production of lower quality food. [FN140] Additionally, studies show that when cattle are pasture-raised and grass-fed, their beef naturally has lower levels of total fat than feedlot-raised and corn-fed cattle. [FN141] This finding is important because research consistently shows a strong correlation between diets high in total fat and saturated fat and an elevated risk of heart disease. [FN142] Saturated fat in particular raises the level of low-density lipoprotein, the artery-clogging type of cholesterol, in the blood, which may lead to coronary heart disease. [FN143] Saturated fat is also linked to diabetes, cancer, and a host of other diseases. [FN144] The main sources of unhealthy saturated fats in the American diet are from beef, cheese, and milk.

On Page 3 of that Inuit Paradox article there's this -

A key difference in the typical Nunavik Inuit’s diet is that more than 50 percent of the calories in Inuit native foods come from fats. Much more important, the fats come from wild animals.

Wild-animal fats are different from both farm-animal fats and processed fats, says Dewailly. Farm animals, cooped up and stuffed with agricultural grains (carbohydrates) typically have lots of solid, highly saturated fat. Much of our processed food is also riddled with solid fats, or so-called trans fats, such as the reengineered vegetable oils and shortenings cached in baked goods and snacks. “A lot of the packaged food on supermarket shelves contains them. So do commercial french fries,” Dewailly adds.

Wild animals that range freely and eat what nature intended, says Dewailly, have fat that is far more healthful. Less of their fat is saturated, and more of it is in the monounsaturated form (like olive oil). What’s more, cold-water fishes and sea mammals are particularly rich in polyunsaturated fats called n-3 fatty acids or omega-3 fatty acids. These fats appear to benefit the heart and vascular system. But the polyunsaturated fats in most Americans’ diets are the omega-6 fatty acids supplied by vegetable oils. By contrast, whale blubber consists of 70 percent monounsaturated fat and close to 30 percent omega-3s, says Dewailly.

So, let's try putting everything together. Wild animals are going to be scared when they're attacked and killed but this didn't effect Inuits who were following their traditional diet. Their health deteriorated when they started eating fast food which includes meat from factory farmed animals who aren't living on a natural diet and who suffer stress every minute of their lives. Feeding farm animals on an unnatural diet can lead to disaster.

BSE - Epidemic In British Cattle

Cattle are naturally herbivores, eating grass. However in modern industrial cattle-farming, various commercial feeds are used, which may contain ingredients including antibiotics, hormones, pesticides, fertilizers, and protein supplements.[b] The use of meat and bone meal, produced from the ground and cooked leftovers of the slaughtering process, as well as from the carcasses of sick and injured animals such as cattle or sheep, as a protein supplement in cattle feed was widespread in Europe prior to about 1987.[3] Worldwide, soybean meal is the primary plant-based protein supplement fed to cattle. However, soybeans do not grow well in Europe, so cattle raisers throughout Europe turned to the cheaper animal byproduct feeds as an alternative. The British Inquiry dismissed suggestions that changes to processing might have increased the infectious agents in cattle feed, saying "changes in process could not have been solely responsible for the emergence of BSE, and changes in regulation were not a factor at all."[18] (The prion causing BSE is not destroyed by heat treatment.)

So, it looks like it isn't a case of humans not being designed to eat any meat at all. We're just not designed to eat meat from factory farmed animals raised on unnatural diets. We aren't designed to eat half the stuff that makes up modern Western diets, either. Why is this?

Convenience Foods - History

Modern convenience food saw its beginnings in the United States during the period that began after World War II.[7] Many of these products had their origins in military-developed foods designed for storage longevity and ease of preparation in the battle field.[citation needed] Following the war, several commercial food companies had leftover manufacturing facilities, and some of these companies created new freeze-dried and canned foods for home use.[8] Like many product introductions, not all were successful—convenience food staples such as fish sticks and canned peaches were counterbalanced by failures such as ham sticks and cheeseburgers-in-a-can.[9]

Intensive Animal Farming - History

According to the BBC, the era factory farming per se in Britain began in 1947 when a new Agriculture Act granted subsidies to farmers to encourage greater output by introducing new technology, in order to reduce Britain's reliance on imported meat. The United Nations writes that "intensification of animal production was seen as a way of providing food security."[17] In 1960s North America, pigs and cows began to be raised on factory farms.[18] From its American and West European heartland factory farming became globalised in the later years of the 20th century and is still expanding and replacing traditional practices of stock rearing in an increasing number of countries.[18] In 1990 factory farming accounted for 30% of world meat production and by 2005 this had risen to 40%.[18]

It makes sense to avoid eating meat in our modern world but vegetarians aren't going to be healthy if they eat a lot of other food items which are bad for us.
