Nutritious vegetables/fruits or environmental-friendly?

The top 10 most nutritious vegetables in the world are:

1. Broccoli
2. Spinach
3. Brussels sprouts
4. Lima beans
5. Peas
6. Asparagus
7. Artichokes
8. Cauliflower
9. Sweet potatoes
10. Carrots

And the top 5 most nutritious fruits in the world are:

1. Blueberries
2. Kiwi fruit
3. Strawberries
4. Guava
5. Cranberries

At the meantime, during his search for the perfect apple, John Cloud asked the questions "What's the most efficient way to grow food? How do our food choices affect the environment? What tastes better?". According to Gussow, a reporter for TIME in the 50s, shipping a strawberry from California to New York requires 435 calories of fossil fuel but provides the eater with only 5 calories of nutrition.

So, should we eat the the most nutritious vegetables and fruits even though they are not grown locally, ignoring the environmental effect and the loss of nutrition during the transportation? Or should we eat whatever is available locally and missing out some of the so-called top nutritious ones?

A recent study by Choice magazine found that canned and frozen vegetables, such as frozen English spinach, canned tomatoes, canned greeen beans and canned carrots, can be more nutritious than their fresh counterparts, with the exception of broccoli.

I wonder what are the effects of eating canned vegetables and fruits on the environment, especially when they are shipped from somewhere else?
