But, since we do live on this planet, and since we do need to learn to deal with things the way they are right now, what can we actually do to improve our nutritional lives without breaking the bank?

I've come up with my own top-10 list. Some of the items on it are whimsical and philosophical, and some are concrete, but all are important.

1. "Shelf-life" is not synonymous with "your life." Realize that the biggest mistake we make as consumers is to assume that the companies producing food products have the slightest interest in our nutritional needs.

2. Whenever possible, buy fruits and vegetables that are locally grown and produced. If you live in a big city, try to visit the farmers' market. If you live in the country, try to find local suppliers.

3. Realize that food product "bargains" may not be bargains at all. Longer shelf life translates into lower prices, but at what cost?

4. Prepare in advance. When I say it costs more to eat healthily, I don't just mean money. Convenience and time saving is a big part of the equation. You can even the odds against you by preparing food in advance and taking it with you.

5. Shop more often for perishables. This costs you more time, true, but the payoff is a big one. The nutrition that's lost in fruits and vegetables just by sitting around would astonish you. It doesn't cost any more to buy this stuff fresh than it does old.
