Greef leafy vegetables have more calcium than milk, like cooked spinach, for example. Meat and Eggs can provide CLA. The human body was designed to function on meet and veggies. We have only been eating crap like dairy and grain for a small percentage of our time on Earth.
The body doesn't care where it gets it's nutrients from, as long as it can break down the food to to get to those nutrients. it doesn't matter how long it has been eating an edible.
All one has to do is look at your example of spinach and every other vegetable in reality. One needs gut flora to provide the enzymes to break them down soluble fiber precisely because the digestive system cannot break soluble fiber down on it's own. It is the same case with dairy, i.e. one needs the enzyme lactase to break down the lactose in milk.
