Gabe said:Well
what I was wondering is -- is there a food out there that comes close
to perfection nutritionally wise, something that you could take out in
the woods and live on for a few months without problems?
Not a food, but hundreds of foods, since diversity is protective
and our proto-human ancestors and early man likely had access
to several hundred different types of wild plant foods, along with
modest quantities of animal foods, mostly invertebrates in the
earlier days. Mostly or all raw. Cooking tends to destroy the
protective phytochemicals of plant foods, and recent studies have
found that while raw vegetables are most protective for certain
types of cancers, cooked vegetables can yield a null effect.
But, if you seek the single cultivated plant food that has the
highest nutrient density (considering only vitamin and mineral
DRIS) the winner is Swiss chard. Not that you should eat it in
abundance, though, because it is also high in oxalic acid, which
will inhibit absorption of some of the minerals.
Quoted message said:Also, are
potatoes good or bad?
Regular potatoes are not as protective as non-starchy vegetables
or even other starchy vegetables such as the sweet potato or
winter squash. Some nutritionists think that regular potatoes
should be excluded from the recommended 5-7 servings of
fruits/vegetables per day.

You could do far worse. You could also do better.
Quoted message said:but this low carb
thing has really confused me.
It's an oversimplification. You shouldn't limit non-starchy
vegetables, eat as much as you can, different ones, preferrably
raw. For starchy vegetables, which are not as protective as
non-starchy ones but provide a more concentrated source of
calories, try to choose the more colorful ones. Some can be
eaten raw if shredded or grated. All diets, regardless of
macronutrient ratios, appear to be healthiest when the soluble
fiber fraction is high to very high, but this usually also means
a moderate to high total carbohydrate fraction. Depending on
how one defines high.
