I don't know about Hindus or whatever, I'm guessing there's SOME animal element in their diets even if they don't know it.
Hindus traditionally don't eat beef, but they do eat dairy, which is a significant source.
Ah; but that high-meat diet is what is responsible for the fact that westerners are so large, tall and strong.
You forgot to mention the higher incidence of heart disease, cancer and obesity the western diet promotes.
Yeah; we're not designed to eat such a high volume of carbohydrates, particularly complex carbohydrates like starch.
Carbohydrates have a huge energy density; if you don't use that energy, it gets stored as fat, and too much fat is a very bad thing indeed.
So let me get this straight: Meat is good, because it has high energy density, but carbohydrates are bad because they have high energy density.
Also: The human body can digest starch just fine, and specific resistant starches (starches that have a bit of trouble being digested, such as in potatoes) actually have positive health benefits, similar to those afforded by fiber. Most starch, however, is digested plenty.
You're going to have to stop right here and provide a decent source, because my bullshit radar is going off like crazy.
A google search of 'protein diet children growth' threw up about half a dozen articles on the first page alone.
There are sources of protein that are not meat, and it is quite likely that the average American diet provides enough to begin with. If eating less meat would provide a problematically-lesser amount of protein, then, as I said, there are other sources.
I'm not going to argue that protein isn't important for growth. Of course it is. I just don't believe that eating less meat should lead to a deficiency of it, for the reasons stated.
And G-Flex; if you're worrying about Calories, then you're about 5 years behind modern dietary science.
I'm not. You're the one who brought up energy density as a point of contention by saying that meat had higher energy density than plants, and I refuted it.
Meat contains far more valuable nutrients, such as various important amino acids, vitamins and minerals. These high-density nutrients are what allow us to eat low-density nutrient plants like wheat and gain the carbohydrates in those plants without suffering severe malnutrition.
If you would do even the most cursory research, you would know that fruits and vegetables can be very, very, very dense in terms of vitamin and mineral content. Meat happens to provide certain things (e.g. iron) in higher density, but there are plants available for that as well. For amino acids, there are also whole proteins found in plants, not to mention that I'm not advocating for a meatless diet anyway.
You act like I'm talking about carbohydrate staple crops vs. meat here. I'm not. There are other, less calorie-dense plants available that are eaten primarily for their noncaloric nutritional content.
Meat also allows us to eat cyanogenic glycosides; this is vitally important as cyanogenic glycosides show up in a number of important plants, like, oh, wheat, rice, various types of bean, rye and so on. Without methionine and cystine, two sulfur-containing amino-acids present in meat (and usually not present in plants), cyanogenic glycosides turn into cyanide when digested.
Like I said, whole proteins are available in plant form. Soy is an example of one. In addition to those, methionine can be found in certain seeds/nuts.
I'm not sure why you even mention Cystine. It has the same biological use as Cysteine (in fact, Cysteine is its metabolite), which isn't even an essential amino acid; your body can produce it on its own. For what it's worth, Cysteine can also be found in certain peppers, onion, garlic, brussels sprouts, oats, and wheat germ. So it's not really a major concern.
Another reason it's not a major concern is because I'm
not advocating a meatless diet in the first place. Jeez. Even if you eat half the meat your average American eats, you're still going to be eating it likely every day, and in significant quantities. Amino acid consumption is hardly even a concern for vegans, who have quite good whole proteins available to them, never mind someone who actually does eat meat, just slightly less than your average American.
In 2000, total meat consumption (red meat, poultry, and fish) reached 195 pounds (boneless, trimmed-weight equivalent) per person, 57 pounds above average annual consumption in the 1950s (table 2-1). Each American consumed an average of 7 pounds more red meat than in the 1950s, 46 pounds more poultry, and 4 pounds more fish and shellfish.
Seriously, think about this for a second. Americans simply
eat way more meat than they possibly would need to.
And even if it's true, it doesn't necessarily say much.
It's quite possible the Japanese had a fairly limited diet, living on a rather isolated, mountainous island in a rather isolated culture to begin with. So even if we assume that the claim is true, and that the Japanese became healthier after eating more Western food, and even if we conclude that it's due to the presence of more meat, and even if we jump to FURTHER conclusions and say that the increase of height means they're healthier (ignoring other effects, like potentially higher incidence of heart disease), that still only applies as a comparison between the two cases of the Japanese diet, and says nothing of the, say, American diet, which is much more diverse in the first place.
The key here is variety. Americans have access to an extremely wide variety of plants, vegetables, and animal products, so our diets are less likely to be skewed by foreign influence or deficient in anything to begin with. Like I said, we tend to get too much of the stuff that you tend to find in meat and too little of the stuff that you tend to find in plants. Most nutritionists would agree that Americans simply eat too much meat, especially things like red meat and pork.
Eating 'more western food'? What the hell are you on about?
I'm talking about the same thing you were talking about when I said that: The Japanese eating different food post-WWII due to Western influence, such as different kinds of meat and dairy.
