Okay, lets take the real world .... supermarkets .... now lets assume you're a person who realises that benefits of homecooked meal. I can buy the same veggies that a vegetarian can buy, and I can have just the same variety in various metas, cuts of meat, seafood, etc.
Therefore if I were to take the real world market of the supermarket as the basis of one's dietary access ... then that would mean that my variety of food intake = more than a vegetarian.
It matters not the situation, nor the real world place you choose to select, an omnivore's diet is going to be more varied.
The only guarantee inherent to the idea of being an omnivore is the consumption of both meat and vegetable matter. There is no guarantee that an omnivore's diet
will be more varied than a vegetarian's; only that it will contain both meat and plants.
Even assuming the omnivore is quite selective, there is still a limit to the quantity of calories an individual is going to consume in a day. While meat is- without question- an excellent source of some forms of nutrition, its presence displaces other things the eater could be consuming.
Your argument seems to stem from an ideal that omnivores don't take care of thesmselves but I posit that the dietary supplements taken by vegetarians tend to outweigh the dietary supplements necessary for an omnivore that will spend just as much time sortig out their diet as a vegetarian.
Overall, there are things in an omnivore's diet that are not in a vegetarian's diet. Some of these things are good: it's much easier to get b-vitamins; iron is more readily digestable. Some of these things are not: much higher concentrations of omega-6 fatty acids (which have been implicated in heart disease and stroke when out of balance with omega-3s); a possible increase in some forms of cancer, and (in America, at least) a significantly higher chance of contracting foodborne illness.
It is arguable that a vegetarian maintaining a nutritionally balanced diet puts a similar amount of work into doing so as an omnivore attempting to maintain a healthy diet. What does not follow is that the omnivore's diet is superior.
If you can accept that meat/poultry/seafood have benefits, then you must also agree that they represent a useful source of goodness.
If you accept that premise, then you must also accept the hypothetical ... that the accessibility to meats, poultry and fish help benefit a person's diet.
Your argument is not unlike 'What the Tortoise said to Achilles' (Lewis Carroll) ... surely you understand what logic and deduction is?
I do; I'm rather tired of the presumption that they translate into accepting absolutes that don't exist. That fish is a source of omega-3 doesn't mean that walnuts are not, nor does it change that many fish are contaminated with mercury. That beef is a good source of iron doesn't mean that spinach is not, nor that grain-raised beef is high in saturated fat. There are benefits and detriments to both vegetarian and omnivorous diets, and what is ridiculous is this notion that some x=y equation inherently and consistently proves one's superiority to the other.
Your argument stems on the fact that omnivores ALL TEND TO BE LAZY ... surely the same can be said of ANY PERSON ... vegetarian or no ... which is evident in how vegetarians take dietary supplements.
No... My argument is that even the most careful omnivore (or, more to the point, one as careful as a nutritionally aware vegetarian) is displacing one set of benefits and risks for another.
One could argue that omnivorism by its nature
lends itself to being "lazy" far more easily than vegetarianism. The risks of an injudicious vegetarian diet mostly out themselves in what one might call the middle-term: anemia, muscular breakdown, etc., which will become evident after someone has been on such a diet for weeks or months (and hopefully be corrected.) "Injudicious" omnivorism, by contrast, won't necessarily show such signs as long as someone is genuinely consuming a variety of plant and animal foods. But they may suffer from food poisoning immediately, or a heart attack or stroke much down the line. Risks that strike out of the blue or much further down the line are easier to ignore.
Anyways, the basis of my argument is efficiency. What is the most efficient? What will cost the less, what will take the less time, what is best for the body? Surely if it is more efficient to eat red meat and fish, then surely it is superior.
But it
isn't necessarily more efficient. Most of the nutrition that comes from consuming animals comes from the plants they eat. There's a reason many cultures have taboos against eating carnivores. They're more likely to pass on diseases... And they're far less nutritious.
For iron, protein, and b-vitamins, meat does well. For almost every
other vitamin, green and orange plants provide superior nutrition.
As for costs... The prices of both industrial meat and industrial produce are artificial. Without significant subsidies, neither would exist in its present form. They strip the soil, drain and poison water supplies, and promote illnesses in crops, herds, and quite possibly people. But feed animals tend to be the bigger problem, and their relative
inefficency is part of that problem. Depending on how one calculates, between two and six pounds of grain goes into making one pound of beef.
if it takes an artist to create a masterpiece in half the tyime, using half the materials, at half teh cost, as it takes another artist to create the same level of masterpiece ... then surely the former artist is superior to the latter artist.
The phrase "caveat emptor" comes to mind. If it takes one artist half the time, half the materials, and half the cost... Look for cut corners.
Which is really what it comes down to.
I'm not saying that it isn't possible to be a very healthy omnivore. What I am saying is that even an "idealized" omnivore accepts certain detriments and risks as well as benefits to their diet. Just as a vegetarian, even an "idealized" vegetarian,
also accepts certain detrminets, risks, and benefits- but largely a different set. Not superior or inferior. Different.
The farther away you get from that ideal- when you get into the way people actually eat, the more glaring the risks and detriments of an omnivore's menu become, while vegetarians will usually either find their way around their diet's particular risks or detriments- or return to being omnivores.
(Oh, and I haven't got anything to say about pesticides and hormones ... personally I think it's a crock ... as the CSIRO and other scientific/regulatory bodies regularly monitor our induistries to make sure that the product we eat and ship overseas is of prime quality. I'm more worried what they do to veggies and grains then I am cattle ... atleast old-style animal husbandry that lent itself to the creation of cattle is less scary than GM foods .... and atleast fish are safe

)
"Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) delivers solutions for agribusiness, energy and transport..." ...Sounds rather like the USDA (United States Department of Agriculture.)
It's wise to read the words of any body simultaneously responsible for
oversight and
promotion of an industry with a grain of salt. Particularly when one of those functions tends to lead to financial gain and the other to financial loss.
And I'm sorry to say that Australia seems to warn against mercury in several species of fish, just like everyone else.
