Topic: What information is available that shows people must eat animal protein to be healthy?
June 17, 2019 / By Alpin Question:
First of all, I don't believe this assertion.
Is there anything other than masses of misinformed people, and the marketing departments of animal food businesses that shows any link between the two? There is no secret about the relationship between industry lobbyists and government agencies which have there be food groups such as "meat" and "dairy." Other countries in the world have food guides which are not centered around animal food like this.
I would honestly like to know if there is any solid credible information in favour of "animal protein being necessary."
Okay exsft. I am not talking about animal protein compared to no protein, (get real,) but to readily available sources of vegetable protein. I'm also not talking about poor people in the developing world here.
So back to my question.

Science has shown - based on the study of comparative dentition, anatomy, physiology, and biochemistry - that humans are an omnivorous species rather than herbivores as contested in many discourses on vegetarianism or purely carnivores as contested by those opposed to vegetarianism. That means humans can eat pretty anything, that doesn't actually kill them, no matter how poor in nutrition it is.
Like the carnivores, we have fairly simple digestive systems well suited to the consumption of animal protein, which breaks down quickly. The human small intestine, at 23 feet, is a little under eight times body length (assuming a mouth-to-anus "body length" of three feet). This is about midway between cats (three times body length), dogs (3-1/2 times), and other well-known meat eaters on the one hand and plant eaters such as cattle (20 to 1) and horses (12 to 1) on the other. This is not to say that we are meant to eat meat, just that we are capable of digesting it and making use of the proteins and other nutrients in it. This mid point supports the other evidence that we are omnivores.
Herbivores also have specialised digestive organs capable of breaking down cellulose, the main component of plant tissue. Humans find cellulose totally indigestible. Plant eaters have to take their time with it. If humans were ruminants (cud eater), for instance, they may have evolved a stomach with four compartments, enabling regurgitation to allow re-chewing of food. Or they may have evolved an enlarged cecum, a sac attached to the intestines where, like rabbits, food is stored until their intestinal bacteria can digest it. Digestion of this type takes place by a process of fermentation where the bacteria actually eat the cellulose and the host animal consumes what results.
The story is roughly the same with teeth. Humans are equipped with an all-purpose set of dentition equally suited to meat and plant matter. Humans' dentition evolved for processing starches, fruits, and vegetables, not tearing and masticating flesh. Our oft-cited "canine" teeth are not at all comparable to the sharp teeth of true carnivores. Other plant-eaters, like gorillas, horses, and hippos, have "canines", and chimps, who are almost exclusively vegan, have massive canines compared to ours.
This discourse could extend into the realms of binocular vision, sleep patterns, and many other of the cases brought by both sides of the debate but there is little point and it wouldn't answer the question.
There have been no studies, either scientific or otherwise, that have shown that humans must eat any animal products, protein or any thing else, to remain healthy or survive.
Just the reverse is true.
There have been countless papers from medical and scientific research and practise that has shown that the consumption of animal products leads to heart disease, cancer, diabetes, osteoporosis, and other degenerative disease - not to mention bacterial, viral, and prion based diseases. This has been exhaustively demonstrated beyond any doubt. If humans were natural carnivores then eating meat wouldn't cause these problems. The fact that health can be regained by laying off meat and dairy is powerful evidence that humans should not be eating those foods in the first place.
There are 22 standard amino acids, the building blocks of all proteins, that are required by all animal life, including humans. Of these there are 11, known as the essential amino acids. Essential amino acids are "essential" not because they are more important to life than the others, but because the body does not synthesize them, making it essential to include them in one's diet in order to obtain them. There are 8 essential amino acids required by all humans phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, and lysine, plus cysteine, tyrosine, histidine and arginine are required by infants and growing children. All of these essential amino acids, and the other 10, can be found in; and digested, absorbed, and metabolised from; plant matter.
This could also extend in to the environmental and ethical issues surrounding farming and slaughtering but I'll leave at that..

Hi Black Cards!
Probably a better way to think about the diet is LCHF - you will need the high fat for your new fuel source.
Carbs are in many foods, including wheat (bread, cereal, pasta), rice, fruits (sugar/fructose), milk (lactose), veggies (potatoes have high carb while spinach/broccoli is low).
It depends upon what method you are going with as to how many carbs you ingest. With Atkins, induction phase (losing weight) is under 20g/day. After that you can add more to get more variety in your diet (usually in terms of fruit/veggies). There is also the paleo method which I suppose I'm on in a varied sort of way. I generally have less than 60g/day.
Don't cheat - cheating is bad for your body. Basically, you need to get your body into a state of ketosis when you are using fat for fuel. If you cheat, even one it can take a week or longer to get back to that state. You'll be spinning your wheels. After you lose the weight you can cheat but I definitely don't as it is not good for my health.
1)"Low carb..no beans, grains, dairy, ceteal. Could cause gout. Not good. Balanced diet, better."
Gout is caused by increased uric acid in your system, a direct result of increased sugar/fructose ingestion. You. Idiot.
Full source, please. Complete nonsense.
Low-carbohydrate diet has a much greater sustained affect on weight loss than low-fat. And so my brain isn't functioning right now? I better eat some carbs! Your body actually uses fat for fuel. Carbohydrates get in the way.
"So you may notice you cannot focus and have headaches on that diet. It is your brain telling you that it is starving."
Completely ludicrous. Are you making this up as you go? Your focus actually is strengthened and headaches go way, as does indigestion, heartburn, constant hunger, weight, blood inflammation, cholesterol, uric acid, etc. Starvation and ketosis are two entirely different states.
Common Dumb Statement #12: "If you are really serious about weight loss, unfortunately the only way to lose weight is by burning off more energy (calories) than you take in."
This is a no-brainer but thank for sharing. Unfortunately it is very misleading. It treats all calories the same.
"The recommended intake for diet is 45-65% of your daily calories for carbs, while protein is only recommended to be 10-35%."
Sounds like a government spoken script. Always trust the government who came up with low-fat diet around 30 years ago. Due to the massive explosion of obesity and diabetes in this country, I'm glad you still spreading lies. Thank you.
"Katie+ High protein, low carb diets are also linked to the development of Cardiovascular Diseases."
Source? Pure unadulterated crap. Total blood inflammation due to decreased sugar intake is the norm. Also, compare any triglyceride or LDL level against a low-fat diet any you'll be blown away. Just because you lose weight, or are skinny eating low-fat does NOT mean you are healthy internally. Sorry to break the news.
"You also don't supply your body with the appropriate energy to function, which means you won't have the energy to say, work out efficiently."
Damn, I better stop weight lifting, I must be doing it wrong. I guess I'm inhaling carbohydrates from the air in the locker room prior to working out.
"High protein diets also usually go hand in hand with high fat diets (think atkins... nothing good
comes from atkins..)"
Not true. Most low-carbohydrate lifestyle individuals I know are LCHF (high fat). Too much protein is indeed an inflammatory but those actually versed in a wee bit of science and clinical (not meta data science) trials will know this.
"High fat diets raise your body's Fat Storage setpoint, meaning they cause you to store a higher percentage of energy as fat than you would on a balanced diet."
Um, no your body immediately burns the fat for fuel. Insulin is sleeping quietly while your body functions normally.
"High carb diets (complex carbs) lower your body's setpoint, causing the opposite effect. (refined/processed carbs do the same thing as high fat diets)"
Hate to inform you but putting the word "complex" before something else does not mean it is instantly healthy. All carbohydrates have an affect on human blood-glucose level, including "complex" carbohydrate.
"Keep in mind, a "diet" does not necessarily mean eating less, it means eating healthy. Make sure you are eating healthy. A healthy diet promotes a healthy body, and that's what you are going for (I hope)"
I would love to get your full lipid panel results for posting here.
There is no evidence, report or scientific data that concludes that animal protein is necessary. How could there be when over 7,000,000 Germans, 4,000,000 Brits, 1,000,000 Americans etc. walk, talk and breath every day to disprove it?
EDIT: In response to the assertion that you cannot get vitamin B12 from a non animal source......
What is B-12 derived from? Isn't it always from an animal product?
B-12, when used to fortify foods, is generally synthetic or fungal in origin. While it is commonly found in animal products, it is now more readily available in soy milks, meat analogues, and Vegetarian Support Formula (Red Star T-6635+) nutritional yeast.
So........better start finding a new definition of the word 'ziltch'.
don't read Good Calories,Bad Calories by Gary Taubes.
animal protein isn't necessary for survival but he pretty much provides scientific evidence that eating grains isn't healthy. and it's hard to get enough calories as a vegetarian/vegan without eating grains or products made from grains. feel free to believe vegetarian propaganda that disputes the claim.
While there are amino acids in vegetables, you need a wide variety of plants to get ALL the amino acids to create a complete protein. LOL! You are funny. Why not talk about poor people in the developing world? Does it not meet your criteria to prove your point. It is soooooo difficult when people actually have points that disprove yours, isn't.
Meat, by itself, is a complete protein. People who are not obsessed with their diet tend to eat it and not have to worry about which amino acid have I missed?
Here's another. With a lot of care, work, and a good bank account, you can get the protein you need from a plant based diet. But you do need Vitamin B12 and it's not available from any plant sources. None. Zilch.
--"Because the amino acids in whole plant foods are harder to extract due to the indigestibility of some plant cell walls, vegans need about 10% more protein than non-vegetarians. For that reason, I have inflated the RDA for vegans by 10%. The RDA for protein is supposed to cover the needs of 97.5% of the population, but the average adult between 19 and 50 years old needs only .66 g per kg of ideal body weight per day (the average vegan would therefore need .73 g per kg) (1)."--
For Lynn: I don't need a "new" definition for zilch. There is absolutely no plant source for B12. None, zilch. VeganHealth, the Vegan Society, VRG, any major veg*n website will tell you that you need to supplement your diet with B12. There are high processed foods fortified with B12, but it's not from plants. It's from a lab somewhere made from who knows what? My B12 comes from a natural source. The cows eat grass, they make B12 in their gut and store it in their flesh. I eat the flesh. It's how humans evolved and it's worked pretty darn well for millions of years.
i've never seen a study that specifies that animal proteins are required for a healthy diet. Not a one.
(Notice how some answers immediately change the topic to needing protein in general - and not specifically animal protein, which is actually what you are talking about. It is said people can't put down their own agendas long enough to actually answer the question)
Yes, people Living here in America (that have money) do NOT have to eat animal protein to be healthy. Happy? They have big supermarkets, time, and money. The majority of the worlds population does not as exsft explained.
